Research design refers to the strategy that is chosen to overall integrate the
components of a study in such a way that it addresses the research problem effectively. The
research problem that is determined, determines the research design that ought to be applied
to effectively address the problem. Types of research designs include; descriptive,
correlational, experimental, semi-experimental, reviews and meta-analytic. This assignment
will review the research designs used in the questions 1,2 and 3 the strengths, weaknesses,
and rationale for the research design chosen.
In question one, to determine the more effective agent between soap and water and
alcohol rubs in preventing nosocomial infections, the appropriate research design to use is
experimental research design. The rationale for using experimental research design is that it
offers the researcher can be able to draw causal relationships between the two interventions
hence be able to establish the effect of each intervention. The advantage of the design is that
the design is repeatable allowing for the verification of the research findings, the design also
allows for the researcher to create conditions that are not necessarily found in natural settings
hence be able to have a better control of the extraneous variables. The weakness of the
research design s that the design is able to draw the causal relations between the two
interventions but does not answer the question of as to why one of the interventions is more
effective than the other.
In question 3, in comparing the effectiveness of influenza vaccine on its ability to prevent the
disease, a correlational case-control study design will be the design of choice. The rationale
for choosing this design is that it provides the researcher with the ability to retrospectively
determine the impact of exposure to the vaccine on preventing the illness compared to
patients not vaccinated (Omair, 2015). The advantages of the research design are that it takes
less time and resources to conduct the study since outcomes have already occurred, they
hence are easier to conduct and involve fewer costs. The weaknesses of the research design

are that the design has a high data quality issues due to patient recall biases and difficulties in
identifying suitable control groups and controlling confounding variables.
The study question 2, which aims to study the effectiveness of anti-depressive medications
on depression and anxiety, a systematic review would b an effective research design to
answer the research question. The systematic review research design is a design that utilizes
an in-depth analysis of previous research literature that is current and relevant to the research
question to derive conclusions based on the findings of the literature (Ganeshkumar &
Gopalakrishnan, 2013). The research design is effective for this study as it provides the
researcher with the ability to review research from other various previous research articles on
the subject and establish a conclusion on the effectiveness of the medications based on the
findings of the researches reviewed. The advantages of using systemic reviews are that it
allows for the analysis of a large evidence body hence providing most up to date information
and minimizes bias in reaching to the conclusion of the effectiveness of an intervention. The
design enables the researcher to understand which intervention works hence will be
imperative in informing the effectiveness of the medications. The drawbacks of the design are
that the reviews require time and are often rigorous to conduct hence a hectic approach to
research.
In summary, the different research designs are suitable to answer different research
problems. It is imperative for researchers hence, to identify the appropriate research design
by initially considering the ability of the design to answer their research question and
considering the pros and cons of applying the design within their research contexts.
