Question Description

I’m trying to study for my Psychology course and I need some help to understand this question.

Application: Case Study – Personality Disorders

Chaotic lifestyles, chronic life interruptions, fractured support systems, and frayed identities collectively describe some of the characteristics of individuals who suffer with personality disorders. Individuals with personality disorders are similar to children navigating through life confused and unsure. Even when surrounded by family and friends, individuals who suffer with personality disorders may feel isolated and alone. As a future professional in the field of psychology, assigning a diagnosis of personality disorder may be very complex.

For this Application, review the case study in the Learning Resources. Consider important client characteristics for developing a personality disorder diagnosis. Think about your rationale for assigning a particular diagnosis on the basis of the DSM.

The Assignment (3–4 pages)

  • A DSM diagnosis of the client in the case study
  • An explanation of your rationale for assigning the diagnosis on the basis of the DSM
  • An explanation of what other information you may need about the client to make an accurate diagnosis based on the DSM diagnostic criteria

A DSM diagnosis of the client in the case study

Diagnosing antisocial personality behavior is a complex process because the patient
should have a history of conduct, which in most cases can be traced from the young age of 15. A
full psychological assessment is vital when a suspected case of antisocial personality behavior is
involved because failure to manage it in time may have severe consequences. For instance, some
patients may end up becoming psychopaths if they do not receive the necessary medical and
behavioral help (American Psychiatric Association, 2013; Laureate Education, 2012). To
diagnose antisocial personality disorder, the individual should be at least eighteen years of age
and portray three of the following characteristics: repeatedly deceitful, constantly break the law,
irritable and aggressive, lack remorse whenever they are on the wrong and lack basic planning
skills hence impulsive in every decision they make. Patients also have a disregard for their safety
and the safety of other people and are irresponsible in everything they do.

It is easier to diagnose people above the age of 18 with antisocial personality behavior
because they are past the challenging teen years and their actions are not likely to be influenced
by hormonal changes that affect people in the adolescent stage causing conduct disorder (Jovev
et al, 2013). As these patients age, their behavior worsens and is more visible even to family
members and friends. To better diagnose a patient suffering from antisocial personality disorder,
the criteria outlined in the Diagnostic and Statistical Manual on Mental Health Disorder is used.
It helps in better assessment of mental health patients so that they can get professional help
(Paris, 2015). The outline suggests interviewing the patient about their behavior and symptoms
as well as the severity of those symptoms. The frequency and duration of symptoms are also



recorded and patients are asked to fill a few questionnaires to eliminate the chances that they
could be suffering from another developmental, personality, behavioral, or mental disorder like
schizophrenia, bipolar, or ADHD (Haelle, 2020).

An explanation of your rationale for assigning the diagnosis based on the DSM

A detailed diagnosis as described above is vital because multiple personality disorders
have similar symptoms. Also, there is a lack of laboratory tests capable of diagnosing specific
personality disorders and doctors have to rely on multiple diagnostic tests and questionnaires to
get a better understanding of patient symptoms while ruling out physical illness as well as other
personality disorders. Doctors also have to work closely with psychologists and psychiatrists to
assess an individual suspected to have a personality disorder before a conclusive diagnosis is
made. There are two discrete diagnosis criteri...
