The answer lies in how clearly you articulate the criteria for selecting data sources; (b) your ability to purposefully select cases; and (c) the extent to which those cases are “information-rich… for in-depth study” (Patton, 2015, p. 264) with respect to the purpose of the study.

As you prepare for this week’s Discussion, consider turning your attention to the variety of purposeful sampling strategies you may consider in developing your research plan. Also consider that qualitative researchers seek a threshold or cut-off point for when to stop collecting data. There is no magic number (although there are guidelines). Rather, saturation occurs as an interface between the researcher and the data and (b) between data collection and data analysis to determine when enough is enough.

For this Discussion, you will critique a sampling strategy used in a research article.

To prepare for this Discussion:

  • Review the Guest, Bunce, and Johnson article; the Yob and Brewer article; and the Learning Resources related to sampling and saturation for this week.

FIELD METHODS 10.1177/1525822X05279903 Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? How Many Interviews Are Enough? An Experiment with Data Saturation and Variability GREG GUEST ARWEN BUNCE LAURA JOHNSON Family Health International Guidelines for determining nonprobabilistic sample sizes are virtually nonexistent. Purposive samples are the most commonly used form of nonprobabilistic sampling, and their size typically relies on the concept of “saturation,” or the point at which no new information or themes are observed in the data. Although the idea of saturation is helpful at the conceptual level, it provides little practical guidance for estimating sample sizes, prior to data collection, necessary for conducting quality research. Using data from a study involving sixty in-depth interviews with women in two West African countries, the authors systematically document the degree of data saturation and variability over the course of thematic analysis. They operationalize saturation and make evidence-based recommendations regarding nonprobabilistic sample sizes for interviews. Based on the data set, they found that saturation occurred within the first twelve interviews, although basic elements for metathemes were present as early as six interviews. Variability within the data followed similar patterns. Keywords: interviewing; saturation; variability; nonprobability sampling; sample size; purposive While conducting a literature review of guidelines for qualitative research in the health sciences, we were struck by how often the term theoretical saturation arose. Article after article recommended that purposive sample sizes be determined by this milestone (e.g., Morse 1995; Sandelowski 1995; Bluff 1997; Byrne 2001; Fossey et al. 2002), and a good number of journals in the Financial support for this research was provided by the U.S. Agency for International Development through Family Health International, although the views expressed in this article do not necessarily reflect those of either organization. The authors thank Kerry McLoughlin (Family Health International), Betty Akumatey (University of Ghana, Legon), and Lawrence Adeokun, (Association for Reproductive and Family Health, Ibadan, Nigeria). Without their hard work, this article would not have been possible. Field Methods, Vol. 18, No. 1, February 2006 59–82 DOI: 10.1177/1525822X05279903 © 2006 Sage Publications 59 60 FIELD METHODS health sciences require that theoretical saturation be a criterion by which to justify adequate sample sizes in qualitative inquiry. Saturation has, in fact, become the gold standard by which purposive sample sizes are determined in health science research. Equally striking in our review was that the same literature did a poor job of operationalizing the concept of saturation, providing no description of how saturation might be determined and no practical guidelines for estimating sample sizes for purposively sampled interviews. This dearth led us to carry out another search through the social and behavioral science literature to see if, in fact, any generalizable recommendations exist regarding nonprobabilistic sample sizes. After reviewing twenty-four research methods books and seven databases, our suspicions were confirmed; very little headway has been made in this regard. Morse’s (1995:147) comments succinctly sum up the situation; she observed that “saturation is the key to excellent qualitative work,” but at the same time noted that “there are no published guidelines or tests of adequacy for estimating the sample size required to reach saturation.” Our experience, however, tells us that it is precisely a general, numerical guideline that is most needed, particularly in the applied research sector. Individuals designing research—lay and experts alike—need to know how many interviews they should budget for and write into their protocol, before they enter the field. This article is in response to this need, and we hope it provides an evidence-based foundation on which subsequent researchers can expand. Using data from a study involving sixty in-depth interviews with women in two West African countries, we systematically document the degree of data saturation and variability over the course of our analysis and make evidence-based recommendations regarding nonprobabilistic sample sizes. We stress here that we intentionally do not discuss the substantive findings from our research; they will be presented elsewhere. This is a methodological article, and we felt that including a discussion of our study findings would be more distracting than informative. We do provide some background for the study, but our focus is mainly on the development and structure of our codebook and its evolution across the analysis process. NONPROBABILISTIC AND PURPOSIVE SAMPLING Calculating the adequacy of probabilistic sample sizes is generally straightforward and can be estimated mathematically based on preselected parameters and objectives (i.e., x statistical power with y confidence intervals). In Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 61 theory, all research can (and should when possible) use probabilistic sampling methodology, but in practice, it is virtually impossible to do so in the field (Bernard 1995:94; Trotter and Schensul 1998:703). This is especially true for hard-to-reach, stigmatized, or hidden populations. Research that is field oriented in nature and not concerned with statistical generalizability often uses nonprobabilistic samples. The most commonly used samples, particularly in applied research, are purposive (Miles and Huberman 1994:27). Purposive samples can be of different varieties— Patton (2002), for example, outlined sixteen types of purposive samples— but the common element is that participants are selected according to predetermined criteria relevant to a particular research objective. The majority of articles and books we reviewed recommended that the size of purposive samples be established inductively and sampling continue until “theoretical saturation” (often vaguely defined) occurs. The problem with this approach, however, is that guidelines for research proposals and protocols often require stating up front the number of participants to be involved in a study (Cheek 2000). Waiting to reach saturation in the field is generally not an option. Applied researchers are often stuck with carrying out the number of interviews they prescribe in a proposal, for better or worse.1 A general yardstick is needed, therefore, to estimate the point at which saturation is likely to occur. Although numerous works we reviewed explain how to select participants (e.g., Johnson 1990; Trotter 1991) or provide readers with factors to consider when determining nonprobabilistic sample sizes (Miles and Huberman 1994; Bernard 1995; Morse 1995; Rubin and Rubin 1995; Flick 1998; LeCompte and Schensul 1999; Schensul, Schensul, and LeCompte 1999; Patton 2002), we found only seven sources that provided guidelines for actual sample sizes. Bernard (2000:178) observed that most ethnographic studies are based on thirty-sixty interviews, while Bertaux (1981) argued that fifteen is the smallest acceptable sample size in qualitative research. Morse (1994:225) outlined more detailed guidelines. She recommended at least six participants for phenomenological studies; approximately thirty-fifty participants for ethnographies, grounded theory studies, and ethnoscience studies; and one hundred to two hundred units of the item being studied in qualitative ethology. Creswell’s (1998) ranges are a little different. He recommended between five and twenty-five interviews for a phenomenological study and twenty-thirty for a grounded theory study. Kuzel (1992:41) tied his recommendations to sample heterogeneity and research objectives, recommending six to eight interviews for a homogeneous sample and twelve to twenty data sources “when looking for disconfirming evidence or trying to achieve maximum variation.” None of these works present evidence for their recommen- 62 FIELD METHODS dations. The remaining two references—Romney, Batchelder, and Weller (1986) and Graves (2002)—do provide rationale for their recommendations for quantitative data and are discussed later in the article. STUDY BACKGROUND The original study for which our data were collected examined perceptions of social desirability bias (SDB) and accuracy of self-reported behavior in the context of reproductive health research. Self-reports are the most commonly used measure of sexual behavior in the health sciences, and yet concern has been raised about the accuracy of these measures (Brody 1995; Zenilman et al. 1995; Weinhardt et al. 1998; Schwarz 1999; Weir et al. 1999; Crosby et al. 2002). One of the key factors identified as affecting report accuracy is a participant’s concern with providing socially desirable answers (Paulhus 1991; Geary et al. 2003). Our study was therefore designed to inform HIV research and intervention programs that rely on self-reported measures of sexual behavior. Using semistructured, open-ended interviews, we examined how women talk about sex and their perceptions of self-report accuracy in two West African countries—Nigeria and Ghana. We solicited suggestions for reducing SDB and improving self-report accuracy within various contexts. In addition, we asked participants to provide feedback regarding methods currently used to mitigate SDB within the context of HIV research and prevention, such as audio-computer-assisted self-interviews (ACASI) and manipulating various aspects of the interview. METHODS Sampling and Study Population A nonprobabilistic, purposive sampling approach was used. We wanted to interview participants at high risk for acquisition of HIV and who would be appropriate candidates for HIV prevention programs in the two study sites. We therefore interviewed women who met at least three basic criteria: (1) were eighteen years of age or older, (2) had vaginal sex with more than one male partner in the past three months, and (3) had vaginal sex three or more times in an average week. Women at the highest risk for HIV in Nigeria and Ghana tend to be engaged in some form of sex work (although not all selfidentify as sex workers), so fieldworkers recruited sex workers for our study. Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 63 TABLE 1 Sample Characteristics Ghana (n = 30) Age Mean Range Years of education Mean Range Number of ethnic groups Marital status Single Married Divorced/separated Widowed Previous research experience Nigeria (n = 30) Combined (N = 60) 26.3 20–35 32.0 1–53 29.1 19–53 6.8 0–12 12 10.3 0–17 3 8.5 0–17 15 20 (66.7%) 0 10 (33.3%) 0 13 (43.3%) 13 (43.3%) 1 (3.3%) 14 (46.7%) 2 (6.7%) 6 (20%) 33 (55%) 1 (1.7%) 24 (40%) 2 (3.3%) 19 (31.7%) In Nigeria, thirty high-risk women were recruited from three sites in the city of Ibadan, which correspond to different socioeconomic environments: brothels, a college campus, and known pick-up points for sex workers. The sampling process was similar in Ghana. Thirty high-risk women were recruited from greater Accra. Three high-risk sites were identified for recruitment and included a red light area, a hotel, and a hostel. Table 1 presents the sample characteristics for the two sites. Data Collection and Analysis The interview guide consisted of six structured demographically oriented questions, sixteen open-ended main questions, and fourteen open-ended subquestions. Subquestions were asked only if a participant’s response to the initial question did not cover certain topics of interest. All respondents were asked identical questions in the same sequence, but interviewers probed inductively on key responses. The guide was divided into the following six domains of inquiry: • • • • • • perceptions of sexually oriented research, discussion of sex and condoms within the community (i.e., among peers), discussion of sex and condoms within the research context, interviewer characteristics, remote interviewing techniques (ACASI, phone interviews), and manipulating the environment of an interview. 64 FIELD METHODS Data were collected between September 15 and December 12, 2003. Interviews were conducted in English, Twi, and Ga in Ghana and in English, Pidgin English, and Yoruba in Nigeria. All interviews were tape recorded, and verbatim responses to each question were translated and transcribed by local researchers, using a standardized transcription protocol (McLellan, MacQueen, and Niedig 2003). Transcripts were reviewed by the principal investigator at each site for translation accuracy and revised when necessary. Thematic analysis was performed on the translated transcripts using Analysis Software for Word-based Records (AnSWR; Centers for Disease Control and Prevention 2004). A codebook was developed by two data analysts, using a standard iterative process (MacQueen et al. 1998). In this process, each code definition has five parts: (1) a “brief definition” to jog the analyst’s memory; (2) a “full definition” that more fully explains the code; (3) a “when to use” section that gives specific instances, usually based on the data, in which the code should be applied; (4) a “when not to use” section that gives instances in which the code might be considered but should not be applied (often because another code would be more appropriate); and (5) an “example” section of quotes pulled from the data that are good examples of the code. In our analysis, the lead analyst created an initial content-based coding scheme for each set of six interviews. Intercoder agreement was assessed for every third interview using combined segment-based Kappa scores run on two double-coded transcripts (Carey, Morgan, and Oxtoby 1996). Coding discrepancies (individual codes receiving Kappa scores of 0.5 or less) were discussed and resolved by the analysis team, the codebook revised accordingly, and recoding performed when necessary to ensure consistent application of codes. The resulting overall Kappa score, by individual question, was 0.82. To identify key themes, we ran frequency reports in AnSWR. THE EXPERIMENT The Methods section refers to the procedures we used in our substantive analysis, yet these procedures did not provide us with the data we needed to determine thematic development and evolution over time and eventually the point at which saturation occurred in our data. We had to develop additional procedures and methods to operationalize and document data saturation. Saturation can be of various types, with the most commonly written about form being “theoretical saturation.” Glaser and Strauss (1967:65) first defined this milestone as the point at which “no additional data are being found whereby the (researcher) can develop properties of the category. As he Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 65 sees similar instances over and over again, the researcher becomes empirically confident that a category is saturated . . . when one category is saturated, nothing remains but to go on to new groups for data on other categories, and attempt to saturate these categories also.” For serious practitioners of the grounded theory approach, the term theoretical saturation refers specifically to the development of theory. Theoretical saturation occurs when all of the main variations of the phenomenon have been identified and incorporated into the emerging theory. In this approach, the researcher deliberately searches for extreme variations of each concept in the theory to exhaustion. Although theoretical saturation is the most commonly used term in published works, frequency of use within multiple bodies of literature has resulted in its meaning becoming diffuse and vague. To avoid propagating this transgression, we rely on a more general notion of data saturation and operationalize the concept as the point in data collection and analysis when new information produces little or no change to the codebook. We wanted to find out how many interviews were needed to get a reliable sense of thematic exhaustion and variability within our data set. Did six interviews, for example, render as much useful information as twelve, eighteen, twenty-four, or thirty interviews? Did any new themes, for example, emerge from the data gathered between interview thirteen and interview thirty? Did adding thirty more interviews from another country make any difference? To answer these questions, we documented the progression of theme identification—that is, the codebook structure—after each set of six interviews, for a total of ten analysis rounds.2 We monitored the code network and noted any newly created codes and changes to existing code definitions. We also documented frequency of code application after each set of six interviews was added. The reasoning behind this latter measure was to see if the relative prevalence of thematic expression across participants changed over time. It could be the case, to take a hypothetical example, that one code in the first round of analysis was applied to all six of the transcripts from one site, implying an initial high prevalence across participants. It could also be true that the same code was never applied in the remaining twenty-four transcripts and that another code emerged for the first time in the seventh transcript and was applied to the rest of the transcripts for a frequency of twentyfour. We needed to assess this variability. We created a cumulative audit trail, updating our records after analysis of each set of six transcripts. So, in our first analysis, we analyzed the first six transcripts, then added six more in our second analysis for an n of twelve, and so on. We started with the data from Ghana and kept adding six transcripts until we had completed all thirty interviews from this site. Six transcripts 66 FIELD METHODS from Nigeria were then added to the analysis for an n of 36, and the process was repeated until all sixty of the interviews from both sites had been analyzed and the code definitions finalized. In all, we completed ten successive and cumulative rounds of analysis on sets of six interviews. Internal codebook structure (conceptually relating codes to one another) was not manipulated until all of the base codes had been identified and all sixty transcripts coded. Below, we provide a summary of these data. Specifically, we present data illustrating the point in analysis when codes were created or definitions changed. We also examine frequency of code application across participants and estimate the point at which the distribution of code frequency stabilized. For all of our analyses, the unit of analysis is the individual participant (i.e., transcript) and data items the individual codes (i.e., expressions of themes). Code Development After analyzing all thirty interviews from Ghana, the codebook contained a total of 109 content-driven codes, all of which had been applied to at least one transcript. Of these codes, 80 (73%) were identified within the first six transcripts. An additional 20 codes were identified in the next six transcripts, for a cumulative total of 100, or 92% of all codes applied to the Ghana data. As one would expect, the remaining 9 codes were identified with progressively less frequency (see Figure 1, the five columns on the left, interviews 1– 30). Clearly, the full range of thematic discovery occurred almost completely within the first twelve interviews—at least based on the codebook we developed (more on this later). Surprisingly, not much happened to the number of codes once we started adding data from the other country. Only five new codes (out of a total of 114) had to be created to accommodate the Nigerian data (see Figure 1, the five columns on the right, interviews 31–60), one of which was new in substance. Four of the five codes were nonsubstantive in nature but were created to capture nuances in the Nigerian data. Two of these four new codes were needed for the unique subgroup of campus-based sex workers in Nigeria who typically do not refer to themselves or their friends as sex workers or to their sexual partners as clients. We therefore needed new codes that were the equivalent of codes used in other transcripts for talk among sex worker friends and talk about sex worker clients, but without the reference to sex workers. The result was two codes that were not new in substance but rather variations of the original codes tailored to the specific situation of the campus-based women. The two other codes were related to researcher qualities. One covered nonspecific statements that researchers’ behavior and attitudes Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 67 FIGURE 1 Code Creation over the Course of Data Analysis Number of New Codes 80 20 5 1-6 7-12 2 2 2 0 1 1 1 13-18 19-24 25-30 31-36 37-42 43-48 49-54 55-60 Ghana Nigeria Interviews were important. The other code was akin to an “other” category and captured infrequently mentioned interviewer qualities. Code Definition Changes Creating a team-based codebook undoubtedly requires making changes to code definitions as data analysis progresses (MacQueen et al. 1998). Since this process itself will ultimately affect the absolute range of thematic expression identified in the data (e.g., if a code is augmented to be more inclusive of certain concepts), we documented all code definition changes throughout the analysis. Table 2 illustrates the progression of definition changes throughout the analysis process. A total of thirty-six code revisions occurred throughout the entire analysis. The majority of changes (seventeen) occurred during the second round of analysis, and after analyzing only twelve interviews, 58% of the total number of changes had been made. Twenty-two of the thirty-six changes were singular in nature; definitions were revised twice for seven of the codes. No definitions were revised more than twice throughout the entire analysis. 68 FIELD METHODS TABLE 2 Code Definition Changes by Round of Analysis Analysis Interviews Round Analyzed Definition Changes in Round Percentage Cumulative Frequency Cumulative Percentage Ghana data 1 2 3 4 5 6 6 12 18 24 30 36 4 17 7 3 2 3 11 47 20 8 6 8 4 21 28 31 33 36 11 58 78 86 92 100 7 8 9 10 42 48 54 60 0 0 0 0 0 0 0 0 36 36 36 36 100 100 100 100 Nigeria data As with the code creation data, adding the Nigerian data to the mix rendered little change to the codebook structure, with only three definition changes across thirty interviews, and these three changes occurred within the first six transcripts from this country. It appears that by the time we began looking at the Nigeria data, the structure of the codebook had been relatively well established, and incoming data offered few novel insights. Codebook definitions also did not change much from a qualitative perspective. Of the thirty-six total code revisions, twenty-eight (78%) were made only to the “when to use” section of the definition, indicating that the substance of the code definition itself did not really change. Rather, clarifications and instructions for application were made more explicit. Of the ten codes whose actual definition changed over the course of the project, seven of the changes made the code more inclusive, thus expanding the conceptual scope of the definition. For example, the code “religion,” which refers to “statements of a religious imperative to tell the truth,” was changed to include both the positive and negative effects of religion on the veracity of self-reported behavior after analyzing the first set of transcripts from Nigeria (see Table 3). Three of the ten definition revisions narrowed the scope of the definition. In Table 3, we present the definitions and subsequent revisions for the seven codes that were revised twice to provide examples of how codes were changed.

Percentages in parentheses under the code name indicate the proportion of the sixty transcripts to which the code was applied. Thematic Prevalence Another critical dimension we needed to address was the overall relative importance of codes, for if codes developed in the early stages turned out to be the most important, doing additional interviews would tend to seriously diminish returns on time (and money) invested in additional interviews. Here, we define the importance of a code as the proportion of individual interviews to which a code is applied. We make the assumption that the number of individuals independently expressing the same idea is a better indicator of thematic importance than the absolute number of times a theme is expressed and coded. After all, one talkative participant could express the same idea in twenty of her responses and increase the overall absolute frequency of a code application significantly. The first question we asked with respect to code frequency was at what point did relative frequency of code application stabilize, if at all? To assess this, we used Cronbach’s alpha to measure the reliability of code frequency distribution as the analysis progressed. We present alpha values between each successive round of analysis, with each round containing an additional set of six interviews (see Table 4). The data transition point from one country to the next is also noted. For the Cronbach’s alpha, .70 or higher is generally considered an acceptable degree of internal consistency (Nunnally and Bernstein 1994). The data in Table 4 show that the alpha value is above .70 between the first two sets of interviews and that reliability of code frequency distribution increases as the analysis progresses, with the greatest increase occurring when the third group of interviews (interviews 13–18) are added. The consistency of application frequency appears to hold even when adding the interviews from Nigeria. In fact, internal consistency is higher for all ten rounds (i.e., both sites) combined (.9260) than for either of the five rounds of data analysis exclusive to each site (Ghana = .8766, Nigeria = .9173). Also, when we average code frequencies for each site and compare the two distributions, reliability between the two data sets remains high with an alpha of .8267. Another question we had concerned the frequency dynamics associated with high prevalence codes, that is, codes applied to many transcripts. Did, Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 73 TABLE 4 Internal Consistency of Code Frequencies Rounds Interviews Cronbach’s Alpha Ghana only 1–2 1–3 1–4 1–5 1–12 1–18 1–24 1–30 .7048 .7906 .8458 .8766 1–6 1–7 1–8 1–9 1–10 1–36 1–42 1–48 1–54 1–60 .8774 .8935 .9018 .9137 .9260 Ghana and Nigeria µGhana, µNigeria 1–30, 31–60 .8267 for example, themes that appeared to be important after six or twelve interviews remain important after analyzing all sixty interviews? Using the categorize function in SPSS, we transformed code frequencies into three groups: low, medium, and high. Based on these data, we found that the majority of codes that were important in the early stages of analysis remained so throughout. Of the twenty codes that were applied with a high frequency in round 1 of the analysis, fifteen (75%) remained in this category throughout the analysis. Similarly, twenty-six of the thirty-one high-frequency codes (84%) in the second round of analysis (i.e., after twelve transcripts) remained in this category during the entire analysis. We showed above that high-frequency codes in the early stages of our analysis tended to retain their relative prevalence over time. But were there any high-frequency codes that emerged later in the analysis and that we would have missed had we only six or twelve interviews to analyze? The data in Table 5 address this question. After analyzing all sixty interviews, a total of thirty-six codes were applied with a high frequency to the transcripts. Of these, thirty-four (94%) had already been identified within the first six interviews, and thirty-five (97%) were identified after twelve. In terms of the range of commonly expressed themes, therefore, very little appears to have been missed in the early stages of analysis. 74 FIELD METHODS TABLE 5 Presence of High-Prevalence Codes in Early Stages of Analysis Frequency after R10 (Sixty Interviews) High Medium Low Number of Codes 36 39 39 Percentage Present in R1 (First Six Interviews) 94 56 62 Percentage Present after R2 (First Twelve Interviews) 97 83 82 DISCUSSION Based on our analysis, we posit that data saturation had for the most part occurred by the time we had analyzed twelve interviews. After twelve interviews, we had created 92% (100) of the total number of codes developed for all thirty of the Ghanaian transcripts (109) and 88% (114) of the total number of codes developed across two countries and sixty interviews. Moreover, four of the five new codes identified in the Nigerian data were not novel in substance but rather were variations on already existing themes. In short, after analysis of twelve interviews, new themes emerged infrequently and progressively so as analysis continued. Code definitions were also fairly stable after the second round of analysis (twelve interviews), by which time 58% of all thirty-six definition revisions had occurred. Of the revisions, more than three-fourths clarified specifics and did not change the core meaning of the code. Variability of code frequency appears to be relatively stable by the twelfth interview as well, and, while it improved as more batches of interviews were added, the rate of increase was small and diminished over time. It is hard to say how generalizable our findings might be. One source of comparison is consensus theory developed by Romney, Batchelder, and Weller (1986). Consensus theory is based on the principle that experts tend to agree more with each other (with respect to their particular domain of expertise) than do novices and uses a mathematical proof to make its case. Romney, Batchelder, and Weller found that small samples can be quite sufficient in providing complete and accurate information within a particular cultural context, as long as the participants possess a certain degree of expertise about the domain of inquiry (“cultural competence”). Romney, Batchelder, and Weller (1986:326) calculated that samples as small as four individuals can render extremely accurate information with a high confidence level (.999) if they possess a high degree of competence for the domain of inquiry Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 75 in question (1986:326). Johnson (1990) showed how consensus analysis can be used as a method for selecting participants for purposive samples. While consensus theory uses structured questions and deals with knowledge, rather than experiences and perceptions per se, its assumptions and estimates are still relevant to open-ended questions that deal with perceptions and beliefs. The first assumption of the theory is that an external truth exists in the domain being studied, that there is a reality out there that individuals experience. Some might argue that in the case we presented, there is no external truth because we asked participants their opinions and perceptions, rather than, say, asking them to identify and name species of plants. This is partially true, but the individuals in our sample (and in most purposive samples/ subsamples for that matter) share common experiences, and these experiences comprise truths. Many women in our study, for example, talked about fear of being exposed (i.e., their involvement in sex work) to the public, particularly via the media. Such fear and distrust is a reality in the daily lives of these women and is thus reflected in the data. The second and third assumptions within the consensus model are that participants answer independently of one another and that the questions asked comprise a coherent domain of knowledge. The former assumption can be met by ensuring that participants are interviewed independently and in private. The latter assumption can be achieved by analyzing data collected from a given instrument compartmentally, by domain. Moreover, the data themselves can provide insights into the degree to which knowledge of one domain transfers to another. Themes that are identified across multiple domains and shared among numerous participants could be identified, post facto, as part of one larger “domain” of experience. Our study included a relatively homogeneous population and had fairly narrow objectives. This brings up three related and important points: interview structure and content and participant homogeneity. With respect to the first point, we assume a certain degree of structure within interviews; that is, a similar set of questions would have to be asked of all participants. Otherwise, one could never achieve data saturation; it would be a moving target, as new responses are given to newly introduced questions. For this reason, our findings would not be applicable to unstructured and highly exploratory interview techniques. With respect to instrument content, the more widely distributed a particular experience or domain of knowledge, the fewer the number of participants required to provide an understanding of the phenomenon of interest. You would not need many participants, for example, to find out the name of the local mayor or whether the local market is open on Sunday. Even a small convenience sample would likely render useful information in this case. Con- 76 FIELD METHODS versely, as Graves (2002:169) noted, “Lack of widespread agreement among respondents makes it impossible to specify the ‘correct’ cultural belief.” It really depends on how you want to use your data and what you want to achieve from your analysis. As Johnson (1998:153) reminds us, “It is critical to remember the connection between theory, design (including sampling), and data analysis from the beginning, because how the data were collected, both in terms of measurement and sampling, is directly related to how they can be analyzed.” If the goal is to describe a shared perception, belief, or behavior among a relatively homogeneous group, then a sample of twelve will likely be sufficient, as it was in our study. But if one wishes to determine how two or more groups differ along a given dimension, then you would likely use a stratified sample of some sort (e.g., a quota sample) and might purposively select twelve participants per group of interest. If your aim is to measure the degree of association between two or more variables using, say, a nonparametric statistic, you would need a larger sample. Graves (2002:72-75) presented an example of a two × two contingency table of height and weight of the San Francisco 49ers. Using a sample of 30, Graves calculated a chi-square value of 3.75 for the association between height and weight. This value is not quite statistically significant at the .05 level. However, when the sample size is doubled, but the relative proportions are kept constant, the chi-square value doubles to 7.5, which is highly significant. Graves (2002:73) therefore recommended collecting samples of between 60 and 120 for such correlative analyses (and, the larger the number, the more ways you can cross-cut your data). 3 Our third point relates to sample homogeneity. We assume a certain degree of participant homogeneity because in purposive samples, participants are, by definition, chosen according to some common criteria. The more similar participants in a sample are in their experiences with respect to the research domain, the sooner we would expect to reach saturation. In our study, the participants were homogeneous in the sense that they were female sex workers from West African cities. These similarities appear to have been enough to render a fairly exhaustive data set within twelve interviews. Inclusion of the younger, campus-based women, however, did require creating a few new codes relatively late in the analysis process, which may signal that their lifestyles and experiences are somewhat distinct from their street- and brothel-based counterparts, but as mentioned earlier, these “new” codes were really just variations on existing themes. Structuring databases in a way that allows for a subgroup analysis and that can identify thematic variability within a sample is one way to assess the cohesiveness of a domain and its relationship to sample heterogeneity. Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 77 A final issue we wish to raise pertains to codebook structure and the ageold “lumper-splitter problem.” Indeed, we have met qualitative researchers whose codebooks contain more than five hundred codes (each with values!). At the other extreme, a researcher may extract only four or five themes from a large qualitative data set. Clearly, the perception of saturation will differ between these two instances; as Morse (1995) pointed out, saturation can be an “elastic” concept. At the crux of the discussion is how and when we define themes and how we eventually plan to present our data. Ryan and Bernard (2003) noted that the problem of defining a theme has a long history, and many terms have been used to describe what we call themes. The authors go on, however, to define themes as “abstract (and often fuzzy) constructs that link . . . expressions found in text” and that “come in all shapes and sizes” (p. 87). Ultimately, themes should be able to be linked to data points; that is, one should be able to provide evidence of a given theme within the text being analyzed. In our view, codes are different from themes, in that the former are formal renderings of the latter. Codes are applied to the data (often electronically), whereas themes emerge from the data. Ryan and Bernard (2004) asserted that when and how saturation is reached depends on several things: (1) the number and complexity of data, (2) investigator experience and fatigue, and (3) the number of analysts reviewing the data. In addition, some researchers warn that completing analysis too soon runs the risk of missing more in-depth and important content (Wilson and Hutchinson 1990:123). While true, we feel that conceptualizing saturation primarily as researcher dependent misses an important point: How many interviews or data points are enough to achieve one’s research objectives given a set research team? Without a doubt, anyone can find, literally, an infinite number of ways to parse up and interpret even the smallest of qualitative data sets. At the other extreme, an analyst could gloss over a large data set and find nothing of interest. In this respect, saturation is reliant on researcher qualities and has no boundaries. The question we pose, however, frames the discussion differently and asks, “Given x analyst(s) qualities, y analytic strategy, and z objective(s), what is the fewest number of interviews needed to have a solid understanding of a given phenomenon?” Could we, for example, go back through our data and find new themes to add to the 114 existing ones? Sure we could, but if we used the same analysts and techniques and had the same analytic objectives, it is unlikely. The data are finite, and the stability of our codebook would bear this out if the original parameters remained constant in a reanalysis. We have discussed codebook development while processing data, as would be expected in a grounded theory approach. But many codebook revisions are removed from the data collection process and consist of restructur- 78 FIELD METHODS ing (usually hierarchically) the relationships between codes after code definitions have been finalized and code application completed. This is true in our case; we first identified as many codes as we thought were relevant to our objectives, finalized the codebook, and then discussed overarching themes. The result of such a process is often a codebook that has several higher level metathemes that may or may not serve as parent codes to children codes. Such post hoc rearrangement does not affect saturation per se—since the range of thematic content in the codebook does not change—but it will likely influence how we think about and present our data. We should also point out that a lumper may identify only a few metathemes in the first place and never have enough codes to bother with ordering themes hierarchically or applying a data reduction technique. Regardless of how one derives metathemes from a data set, if it is these overarching themes that are of primary interest to the researcher, saturation, for the purpose of data presentation and discussion, will likely occur earlier in the process than if more fine-grained themes are sought. Our postcoding data reduction and interpretation process rendered four metathemes. It is difficult to say, post facto, whether we would have had enough context to have derived these metathemes early on in the process, but in retrospect, looking at the metathemes and their constituent code frequencies, enough data existed after six interviews to support these four themes. The basic elements were there. The connections among the codes that eventually made up the overarching themes, however, may not have been apparent in the early stages of analysis, or we may have identified several other themes that dwindled in importance as transcripts were added and the analysis progressed. Nonetheless, the magic number of six interviews is consistent with Morse’s (1994) (albeit unsubstantiated) recommendation for phenomenological studies. Similar evidence-based recommendations can be found for qualitative research in technology usability. Nielsen and Landauer (1993) created a mathematical model based on results of six different projects and demonstrated that six evaluators (participants) can uncover 80% of the major usability problems within a system, and that after about twelve evaluators, this diagnostic number tends to level off at around 90%. 4 Our experiment documents thematic codebook development over the course of analyzing sixty interviews with female sex workers from two West African countries. Our analysis shows that the codebook we created was fairly complete and stable after only twelve interviews and remained so even after incorporating data from a second country. If we were more interested in high-level, overarching themes, our experiment suggests that a sample of six interviews may have been sufficient to enable development of meaningful themes and useful interpretations. We call on other researchers to conduct Guest et al. / HOW MANY INTERVIEWS ARE ENOUGH? 79 similar experiments to see if, in fact, our results are generalizable to other domains of inquiry (particularly broader domains), types of groups, or other forms of data collection methods, such as focus groups, observation, or historical analysis. At the same time, we want to caution against assuming that six to twelve interviews will always be enough to achieve a desired research objective or using the findings above to justify “quick and dirty” research. Purposive samples still need to be carefully selected, and twelve interviews will likely not be enough if a selected group is relatively heterogeneous, the data quality is poor, and the domain of inquiry is diffuse and/or vague. Likewise, you will need larger samples if your goal is to assess variation between distinct groups or correlation among variables. For most research enterprises, however, in which the aim is to understand common perceptions and experiences among a group of relatively homogeneous individuals, twelve interviews should suffice. NOTES 1. Ethics review committees also usually require that sample sizes be written into protocols, and deviating from approved sampling procedures can involve time-consuming protocol amendments. 2. We chose sets of six because six is a divisor of thirty, and this number was the smallest recommended sample size we identified within the literature. 3. Note that although chi-square is highly useful for structured categorical responses, it is not suitable for data collected from an open-ended instrument such as ours. Contingency tables require that the frequencies in one cell are mutually exclusive and contrastive of other cells in the table (i.e., an individual weighs either 200 lb or more or 199 lb and less, or a medical intervention is either successful or not). In the case of open-ended questions, the presence of a trait within an individual (e.g., expression of a theme) cannot be meaningfully contrasted with the absence of this trait. That is, the fact that an individual does not mention something during the interview is not necessarily indicative of its absence or lack of importance. 4. Nielsen and Landauer (1993) also calculated that the highest return on investment was obtained with about five evaluators. It would be interesting to see if these monetary figures transfer to other domains of research. REFERENCES Bernard, H. R. 1995. Research methods in anthropology.

Working Toward the Common Good: An Online University’s Perspectives on Social Change 1 Many institutions of higher education in the United States and indeed around the world are reaching out to their neighborhoods as a member of the community to contribute to the common good through research, service, and educational opportunities. In this descriptive study, the understandings and practices around this kind of activity by one university with a mission of creating positive social change is explored. While current literature indicates that researchers are examining campus-community engagements, very little research has been done on community engagement when the institution works primarily online and the communities involved are geographically dispersed and dependent on individual choices and preferences. The goal of the study was to discover how members of one such online university currently understand and practice the mission to provide a baseline of understandings for curriculum planning and mentoring student research projects and service activities. Through a series of interviews conducted with faculty members, students, and alumni, several themes were identified. These results give rise to several implications for the university in developing its community outreach, along with some suggestions for further research. The discussion of findings for this university might have applicability to other institutions of higher education, both online and traditional, with a similar commitment to the community. Background to the Study With the advances in online education and the significant numbers of institutions that have campuses in multiple locations, the ease with which colleges and universities can demonstrate mission fulfillment is more challenged. The reach of the university is broader in such programs and mission efficacy relies on more than confirmed relationships with constituency groups that are often local to the institution. For online education providers in particular, the strength of mission fulfillment must rely upon intentional promotion within 2 curricular structures, student services, and philosophical expectations that allow university members to carry out the institution’s mission in their own communities. Finding references that speak to mission fulfillment in online and geographically dispersed programs is made particularly difficult given the limited number of writings that deal with this topic. In fact, a review of the literature for mission and online learning finds a greater focus on how the decision to deliver online instruction can become part of the institution’s mission, not upon how the existing mission can be assured through online delivery (Checkoway, 2001; Johnson, et al., 2014; Levy, 2003). The complexity of understanding what is meant by “positive social change”, the mission for the university in this study, adds to the difficulty of using traditional images of “community” within mission fulfillment. Defining and Describing Social Change The term “social change” has been defined and analyzed across the academic disciplines, reflecting the particular perspective of that discipline and its research agenda. In one study, a proposal for social change in schools (Jean-Marie, Normore, & Brooks, 2009), the authors reported that their literature review was aided by such identifiers and organizers as equity, diversity, social justice, liberatory education, race, gender, ethics, urban school, global education, critical pedagogy, oppression, social change, social development, and social order, among others. From the review of the literature around these key terms, Jean-Marie, Normore, and Brooks see social change as bringing about a “new social order” in which marginalized peoples would have the same educational and social opportunities as those more privileged. As the list of identifiers above suggests, the concepts of social justice and equity have been significant in discussions of social change in education, psychology, and social and cultural studies (see also Curry-Stevens, 2007; Drury & Reicher, 2009; Moely, Furco, & Reed, 2008; and 3 Peterson, 2009). The writing and advocacy of Paulo Freire, Ivan Illich, civil rights leaders, and feminists during the last half of the 20th century influenced these understandings and helped shape the particular emphases of social change in recent decades. Hoff and Hickling-Hudson (2011) sought descriptors of social change that would be appropriate for education and noted that Farley, writing in 1990, offered an understanding of social change as “alterations in behaviour patterns, social relationships, institutions, and social structure over time” (Hoff & Hickling-Hudson, 2011, 189). However, Hoff and Hickling-Hudson found this inadequate from an educational point of view because of its value-neutral stance. They preferred a definition that would give social change a “connotation of social progress or social development beneficial to society” (189). For this reason, they chose the definition proposed by Aloni in 2002, which places social change as challenging “trends of discrimination, exploitation, oppression, and subjugation displayed by groups who regard themselves as favored and, thus, take privileges for themselves and deprive other groups of the right to a dignified life” (Hoff & Hickling-Hudson, 2011, 189). In other words, the change in social change is defined here in positive and value-laden terms that relate more particularly to the agents of social change than to others they might want to change. They were careful to add that this cannot be cast in universal or absolute terms, but it is dependent on particular contexts and circumstances (see also Itay, 2008, writing in political science). and Miller (2006), working in continuing education and innovation studies, respectively, identified influences on the meaning of social change arising from new political and social realities. For instance, during the economic recession of the late 1970s and early 1980s, education was seen to be increasingly determined by the needs and forces of the market and less by concerns for equity and social justice, a conclusion suggested also by Atkinson (2010) in 4 adult education and Feldman (2001) in economic history. However, we witness today a movement again toward social justice and equity issues (Ryan & Ruddy, 2015), brought about in part by Occupy activism (e.g., Cortez, 2013), current political debates, experience in campus outreach programs (e.g., Patterson, Cronley, West, & Lantz, 2014), social media (e.g., Taha, Hastings, & Minei, 2015), and exposure to other cultures in a globalized world (e.g., Bossaller, Frasher, Norris, Marks, & Trott, 2015). Armstrong and Miller also noted that increasing global and international contact has led to revisions in the meaning of social purpose narrowly defined in Western terms and contexts and the “grand narrative” of modernism being replaced by less absolute and dogmatic postmodern discourses, an idea echoed also in adult education by Holst (2007). As a consequence, projects with a social change purpose are considered to be more effective when local community partners participate in determining needs and shaping the outcomes collaboratively (Bahng, 2015; Lees, 2007; Lewis, 2004; Nichols, Gaetz, & Phipps, 2015; Silverman & Xiaoming, 2015). Brennan (2008) added that the social context in which higher education operates today calls for universities to be responsive in a number of ways to their constituent societies. One of these responses, playing “a role in constructing the ‘just and stable’ society”, returns the social change mission to the goals of equity, which he suggested includes equitable access to the credentials needed to participate as equals in the new societal realities and guarantees of autonomy and freedom. Furman and Gruenewald (2004), working in educational administration, described yet another new influence on understandings of social change: ecological concerns. Their argument was that “environmental crises are inseparable from social crises” (48), primarily because they usually have to do with the misuse of racial and economic power. 5 Overall, it is apparent that social change and social purpose have been focused primarily on equity issues, although their working definitions, both implicit and explicit, reflect a spectrum of meanings ranging from simple activism around race, gender, and poverty, for instance, to more nuanced understandings of the impact of technology developments, diversity, globalization, as well as the ecological environment. More recently, this focus has received renewed attention as the gap between rich and poor is seen to be widening and the middle class to be diminishing (Gillis & McLellan, 2013; Goldberg, 2012; Guy, 2012). It is important to keep in mind that “social change” can be either an action or a result, product or process, noun or verb. While educators need a clear end-in-view for their work with students, processural understandings of social change may serve them better in planning for the kinds of learning experiences that will bring about the desired results. The central concept of “conscientization” in Freire’s writings on social change speaks as much to process as product (Hickling-Hudson, 2014) and using the concept of “transformation” rather than “results” in reporting on social change projects (e.g., Sewell, 2005; Silverman & Xiaoming, 2015) further supports this. One of the most frequently made distinctions in social change is that between charity and helping on the one hand and change and justice on the other. In many cases, the distinction is assumed (e.g., Moely, Furco, & Reed, 2008); in other cases, it is elaborated. In simplest terms, charity work sets out to help someone; change efforts aim to modify social arrangements toward equity (Mitchell, 2008). In cultural and social studies, charity has been identified as “transactional” service; change and social justice as “transformational” (Peterson, 2009, 541, 545). From a social work perspective, charity seeks to discover the immediate elements of a particular individual’s needs and deal with them; change investigates the wider picture of all 6 those with similar needs and how the whole group might be helped by systemic change (AllenMeares, 2008). In effect, charity addresses the symptoms of a social injustice; change seeks to remove the root causes (Allen-Meares, Mitchell, 2008, Peterson, 2009). The former participants can usually see immediate results for their efforts; the latter work for the long term and may actually never see final results, or at least they will discover that results are usually not immediately apparent (Mitchell, 2008). At its worst, charity may be patronizing, perpetuating rather than overcoming the differential in power—the “us versus them” dichotomy—which may have brought about the need in the first place. At its best, change may not only amend the situation of the needy but also strengthen authentic relationships among all those involved as it redistributes and shares power more equally between those who are privileged and those who are not. In the reciprocity between the needy and change agents, each benefits although in different ways (Peterson, 2009). Writing within the context of human services, Netting, O’Connor, & Fauri (2007) picked up on many of the distinctions between charity and change but put them in an entirely different light. They replaced charity with focused or peripheral change; that is, advocacy for individuals providing “relatively short-term interventions designed to gain access to, utilization of, or improve the existing service delivery system” (60). These interventions are critical in operationalizing an organization’s mission in that they focus on implementing and achieving the intent of particular policies and processes. They are usually manifested as case advocacy— working for “individual clients whose rights have been violated and/or whose access to benefits have been denied” (p. 63). Netting, O’Connor, and Fauri also substituted “change” with “transformation” described as “long-term, structural interventions designed to change the status quo at broad community, state, regional, or even national level” (60). These kinds of 7 interventions may involve “social movement organizations, campaigns for social justice . . . and coalitions with system reform goals” (60). They may threaten the status quo and are usually manifested as cause advocacy—working in “an arena, locus of change, or target,” which may be “an organization . . . legislation, law, and/or community or other large system” (63). While the literature in general clearly weighs in on the side of change over charity, some writers have raised points in favor of taking a more holistic view of social change that includes both charity and change. Netting, O’Connor, and Fauri (2007), for instance, proposed that because both case advocacy and cause advocacy fall within the professional roles of human services providers, both must be planned for and their success evaluated. One argument in favor of a more holistic view is that charity may be needed as a necessary first step to improve immediate and pressing conditions. Change can then subsequently address the policies and social institutions that need reform and/or revitalization (Hoff & Hickling-Hudson, 2011). This argument takes on merit when one considers that change may take time whereas charity may bring some immediate relief. In a similar vein, charity may also be considered an important first step to build trust between social change activists and those for whom they work, which, once established, can be a basis on which to take later steps collectively toward political change (Peterson, 2009). Over two decades ago, Boyer claimed, “At no time in our history has the need been greater for connecting the work of the academy to the social and environmental challenges beyond the campus (1990, xii).” Duderstadt, a decade later, noting some of the pitfalls to an institution of higher learning that arise from the expectation that it will “address social needs and concerns”, nevertheless declares that “it is clear that public service must continue to be an important responsibility of the American university” (2000, 2003, 146). For the purpose of this 8 study, when individuals associated with colleges and universities find ways to serve their local communities and contribute to the common good, their efforts are identified as contributing to positive social change. Research Method The goal of this study was to explore and analyze the current state of understanding and practice around social change at one online university with geographically dispersed students and faculty. We selected a qualitative research design for this study in an effort to get at the understandings of faculty members, students, and alumni in their experience of social change processes and how they make meaning out of those experiences (see Creswell, 2003). The site selected for the project is a comprehensive, regionally accredited, for-profit institution originally founded in 1970 as a distance learning institution. It currently enrolls approximately 60,000 students. The institution is an appropriate site for this research in that creating positive social change was the university’s mission from its founding. The mission statement is prominently displayed in university publications, shared widely with new faculty members and students, and frequently discussed in online forums and other venues. Although the researchers considered both focus and group interviews as data collection methods, we ultimately decided that individual interviews would provide the richest information and would also permit comparisons among interview groups. Informed by both the literature review and the goal for the study, the researchers prepared an interview guide, utilizing cross referencing between the goals for the research and the interview questions. (The interview questions are provided in Appendix A.) A research team, consisting of six faculty members, completed inter-rater reliability training and piloted the interview guide. The study was approved by the university’s Institutional Review Board and appropriate measures were taken to preserve 9 confidentiality of responses with interviewers signing confidentiality agreements and the substitution of pseudonyms for real names in any reporting of the study. A small gift card ($50 for was sent to participants in appreciation for their time and willingness to be interviewed. Working in pairs, the researchers interviewed three groups of participants selected via purposeful, referral sampling from the institution’s faculty, students, and alumni. Interviewees were identified by their colleagues, teachers, or mentors as active participants in social change activities and possessing an ability and willingness to articulate their understandings in a considered way. Eight current students, ten faculty members, and 12 graduates including five very recent graduates made up the pool of interviewees. Interviews were conducted via telephone and transcribed verbatim using digital recordings. For each pair of researchers, there was a lead interviewer and an observer who debriefed after each interview. The observer also kept interview notes and verified interview transcripts; member checks were also used to confirm the accuracy of the transcripts. Two analyses of the responses were undertaken, concurrently but independently, to provide different perspectives for comparison. The analysis began with the interview transcripts, looking for recurring ideas and common themes. The initial and open coding identified key participant responses, followed by a second coding that labeled the nature of the emerging theme. Following the second coding, the researcher developed working definitions for each theme. The interviews were coded a third and final time, during which the working definitions provided a framework for confirming the code, and illustrative quotes were noted. Coded Analysis 10 Significant Common Themes When interviewees were asked to define social change and provide examples from their own experiences, their answers and the responses to follow-up probes yielded richly nuanced and diverse concepts, spanning a wide spectrum of ideas, reflecting the broad sweep of the university’s official definition. Themes emerged about the focus on others, the charitable nature of social change, the way small actions in social change could expand from one or a few to many, and about the central role of education in changing perspectives and bringing about social change. Focus on the “Other” Most participants gave definitions of social change that were “other”-focused; that is, social change was seen as an important goal in order to improve some aspect of life for other people, but not necessarily for themselves. Others might need to benefit from social change, but the participants in this study did not typically include themselves in the change population. For instance, Brian, a faculty member, stated that social change “is anything and everything an individual does to improve the life or lives of others.” In some cases, those “others” had unmet personal needs: their quality of life was seen as insufficient or their wellbeing was somehow in question. Few participants first thought of social systems or community-at-large initiatives as they discussed social change, but they often added the larger community in an expansion of their definition. In some cases, this seemed to be added almost as an after-thought. Ray, an undergraduate faculty member, defined social change “as a group of people who are getting involved, who are giving of themselves, whether it be in terms of time or money or effort or all of the above, to make an impact on both individual people’s lives and society as a whole”. Other 11 respondents took in the larger community immediately. Arsi, for instance, an alumna whose work focused on the intergenerational transfer of learning, spoke of that expansion to the wider community in these terms: “[S]ocial change has a lot to do with making a contribution to society that will not only improve individuals’ lives but will collectively improve the environments in which they live, and that can expand beyond just personal agendas.” Only a few respondents spoke specifically of social change within the boundaries of democracy and related political principles, but the possible expansive nature of social change was a clear theme: “Social change,” stated faculty member Christine, “is tinkering with the world.” Helping and Altering Consistent with the focus on “the other” and with a framework that centers on individual needs, most participants used language associated with helping to describe the actions that support social change. Typical definitions included words such as “contribute”, “serve”, “give”, or “provide”, reinforcing the idea that social change is something that participants initiated for another individual or set of individuals with specific needs. Pam, an alumna who works in mental health, spoke of “project(s) that will kind of better the populations that they’re serving,” while Brian spoke of disadvantaged people and the need to “give them the dignity” of a job. Marg, another alumna, took up the idea of service: “You have something that you see you can start off with service projects or volunteering and charity work and all of that,” but she extended this to include a larger context: “I recognize(d) the social injustices taking place everywhere, in many communities . . .” And Diane, an MBA alumna, stated that “social change is about helping every individual achieve their potential so that they can reach down and help the next one up.” In addition to using language that anchored social change within the concept of helping, many interviewees described their own social change actions in terms of the desired effect on 12 others. They used terms such as “(re)build”, “develop”, “empower”, “improve”, and “modify” to describe the outcomes of their work for social change. Tom, a faculty member with philosophical groundings in the quality movement, strives to encourage people to build on the positive. “Social change is making something better” and encouraging that movement forward. The Ripple Effect The vast majority of respondents noted that a single person can be responsible for social change: only two of the 30 respondents indicated that a “critical mass” (Eileen’s term, further arbitrarily defined as 30% of a population by Diane) was necessary to effect significant social change. However, most participants acknowledged that social change can begin with a single individual but his or her efforts require expansion. Many participants used the term “ripple” to note the movement from the single person to a group of people, and then to a larger impact. Kim, a student who came to the university precisely because of the social change mission, is a teacher. She instructs her own students that “whatever they do should be important to them and make some kind of ripple.” Alumnus Charlie called it a “gravitational wave,” as in physics, that ultimately impacts the farthest reaches of the universe. For the most part, social change was seen in terms of making progress. Paige noted the idea of “paying it forward” and other interviewees used the concept of moving forward in a positive way as part of their social change definition. Over half the interviewees thought that both accentuating the positive and removing the negative were involved in social change, but nearly as many indicated that a focus on the positive was crucial for social change. Only one respondent indicated that the single goal of social change was to remove a negative. The notion of social change by an individual, often for the benefit of another individual, was prevalent. Changing Perspectives and the Role of Education 13 Participants in each interview group identified education as an important feature of how they understand and approach social change. Alice, an alumna who had a successful military career and now focuses her efforts on teaching, put it this way: “Social change to me is being able to, I guess, implement or work hand-in-hand with students to help them further their education so that we help our community become a better community. It's making sure that education is the priority as well as being concerned about the community and the economic status of the community and the children in the schools.” Moreover, each group had representatives who spoke of “transformations” in perspective as a key feature of social change. Brenda, an alumna who studied aging women, linked social change to changing perspectives: “Social change is taking the norms, the mindset, the expectations, the assumptions of a society and beginning to shift them, hopefully in a positive way.” Wendy, an alumna who has started her own school, acknowledged that her hope and her goal “is that kind of the change that the school is in our community--that it goes beyond just the children and the families here, but actually that we start this new conversation of what education can be.” Margaret, a faculty member in human services, spoke of beginning social change at a “very grassroots level, where you can shape a person’s values, or maybe their attitude, maybe their beliefs . . . which in turn, basically diffuses out to other aspects of society.” Secondary Themes Reliance on Context The task of articulating a definition of social change was not simple for most participants. In terms of elaborating on social change definitions and examples, some participants noted the importance of context. Becky, a doctoral student in Public Policy and Administration, focused on context: “Let’s see. Well, that depends on the project. It can be an individual that’s changed 14 something in their life or it could be a process that’s changed or it could be a policy. That’s hard without knowing an example.” Social Change and Benefit to the Initiator “Who is social change for?” As respondents considered the beneficiaries of social change, some admitted that social change action promotes benefit for the change initiator. Paige noted that the first thing that changes in social change is often the self: “Well, I hope first, before anything, we’re changing our lives, who we are, what we believe, and what we think. You have to do that first before you can actually make a difference in the community.” Charlie, an alumnus who has founded a business to promote cross-cultural communications, spoke similarly of the need to build the “self” in order to effect social change: “And by doing that I enrolled [here] and hoped to develop those strengths in myself, which gets back to the Gandhi point that you become the change you want to see by empowering myself, educating myself, engaging myself . . .” Arsi proposed that social change serves a dual purpose. “I think it’s not only for the person that initiates the social change but I think it’s for a broader audience and it can include the community.” Ray stated that this is a “central truth to the human experience. When you help people, you personally benefit, and when you help enough people or you get together a large enough group, you can help society benefit.” Christine admitted, “I think very selfishly. It’s definitely for myself because of all the things that go with it, but I think the goal is that there will be some value or benefit for us universally.” Discussion and Implications The participants in this study were focused on others. an admirable quality, enacting the “servant-leadership model” (Greenleaf, 1977, among others) for improving organizational effectiveness and creating change. A few of the participants acknowledged benefit to themselves 15 in engaging in social change activity, usually in the form of personal satisfaction that can come about by doing something good for others. One interviewee expressed the even more cynical view that all we do is tainted by a level of self-serving. Social justice and equity were seen by some to be objectives for social change action but in the form of bringing about for others what they themselves already possesses. A few spoke of supporting democracy by their actions, where all work together for the common good. The enthusiasm and momentum around helping others was very notable in this group of interviews. By itself, however, a focus on improving conditions for another may not be sufficient for thorough-going social change. Under some conditions, especially when root causes are not addressed, it can be experienced as disempowering and patronizing by the recipients, creating two levels in a community—the helpers operating from a privileged position and the helped operating from a position of need and deficit—and neither level is transformed by the activity. Importantly, it may not always reveal that one might be implicated as a member of a group that could very well be the source of the problem being addressed. As indicated, one of the persistent themes in the scholarly discussion of social change is the clear distinction between charity and helping on the one hand and change and justice on the other. In the coded analysis made of the definitions and descriptions of social change, the theme “charity and alteration” was one of the most prominent. It was described as serving or helping others so that their lives and possibly the lives of an ever widening circle will be changed. The analysis found that the participants in this study tended to speak more often in terms of “charity” than “change”. Real-life examples of social change activity, however, are seldom as clear cut as descriptions of charity and change in the literature suggest. While charity predominates in the 16 descriptions and actions of the participants, and social change activity was conducted by individuals or small groups engaged in the same effort and focused on a specific needy group, and even though most of the change was seen as making a difference in the lives of individuals being served rather than in the systemic structures that make up society and its institutions, many nevertheless saw their activities contributing to change in a larger context. Much of this change was envisaged in terms of hopeful thinking about the long-term potential and “ripple effect” of their efforts, rather than in terms of the impact of deliberately planned or collaborative action. The larger changes were considered post hoc effects rather than outcomes planned from the beginning. Not apparent were strategies based on an analysis of systemic flaws and developed to address root causes, bringing all players into the planning, and being deliberate about making long-term and sustainable changes. The analysis which looked for common themes in the responses produced encouraging news for those who work in higher education. Both faculty members and students spoke of the transformative power of education to change perspectives and attitudes. They spoke of the power of class discussion forums, learning from different others in classes, curricular topics that specifically addressed needs and opportunities for social change activity, practical projects undertaken as class assignments, and the example of faculty members and other students who were engaged in social change activity. Faculty members also spoke of the importance of oneon-one mentoring of students who were in the process of developing a change project. Suggestions for Further Research This study opens up several questions that suggest areas for additional research, some that arise from expanding and strengthening the original study, and others to follow-up on leads from this study. Among the first set of questions is how wide-spread these views and 17 understandings of social change are within the context of this university. So, this interview study with its referral sampling approach might usefully be expanded to the whole university community for a more thorough-going data set, perhaps employing a survey to provide quantitative measures of the strengths of the many responses represented by the sample in the original study. Then too, given that this study was conducted in one institution whose mission is to create positive social change, what would other institutions, traditional and online, find if they were to conduct similar investigations? This question is important if the institution wants to more fully realize its social responsibility in community outreach by providing an initial sense of some of the common themes , with their strengths and weaknesses, that might exist already in the institution. In follow-up on leads from this study, studies of teaching and learning strategies might help determine the most effective for expanding ideas of charity to include a change dimension, and to prepare students in the skills needed for social change as efforts toward justice and equity and/or empowerment and agency. Limitations of the Study This was an exploratory study whose purpose was to discover the understanding and practice of positive social change as a component of the mission of a large U.S. online university. The sample size was small and purposefully selected for the participants’ involvement in social change activities. As a result, it was comprised of a majority of participants who live and study in the United States. There was a general intent to include participants with diverse racial and ethnic background and gender. The end result is a range of values along with diversity in culture, gender, and ethnicity in this group of participants and an equally wide ranging number and kinds of contexts and opportunities for social action being 18 addressed by them. While this is a limitation of the study, it also is representative of the complexity of understanding social change and those who are active within it. Missing from the research design is the involvement of a designated external community in the project. Our identified “community” includes the faculty, students, and alumni of the institution. As faculty members, the researchers are part of this community and we relied upon other faculty, our students, and our alumni to help identify participants, perfect the interview guide, provide a debriefing after each interview, and support member checks. The University’s external communities, less well defined, are all the communities in which our students, faculty, and alumni practice positive social change. The difficulty of creating touch points with all external community constituency groups, challenging even for land-based institutions, would have been prohibitive for a study of this size. Conclusion The findings of this study indicate that faculty, alumni, and students at this particular institution show strong passion to make changes for “the greater good.” It also shows that for those who are actively involved, some of the distinctions made in the literature do not hold in their understandings and practice of social change. Activities that at first glance might seem to fall into the category of charity were also undertaken with the expectation of a “ripple effect” that would manifest itself as change in the broader society. “Helping” and “altering” concepts were used together to describe the purpose of an activity. In other words, service activities were often understood to be aiming for social justice or self-efficacy which takes them out of the realm of simply helping (a potentially disempowering relationship) and into the domain of real change; from a focus on a single individual or group of individuals toward creating an impact through these individuals on the wider community. This move from charity to change was not always 19 fully understood by participants and could be strengthened even further by preparing students in the skills and knowledge to turn their scholarly understandings and personal commitment into even more effective community engagement and long-lasting impact that more deliberately looks to creating systemic change.

The Purpose of the Study
The purpose of the study carried out by Yob and Brewer was to examine how
communities and universities unite in fostering social change (2015). This was achieved through
several interviews.
Research Questions
The two main research questions of the study were:
1. What are the understanding and the practice of social change at the University?
2. How would the knowledge gained assist in encouraging the university to move forward
with the alliance to form social change
Site Selection
The study took place at Walden University. The participants who contributed to the study
were students from the Walden University, faculty members as well as the members of the local
community (Yob & Brewer, 2015).
Type of Purposeful Sampling Strategy Used in the Study
