Association of Social Work Boards (ASWB) Clinical Practice Exam

The client is most likely diagnosed with Major Depressive Disorder, given their medication history. Paxil (paroxetine) and Zoloft (sertraline) are both selective serotonin reuptake inhibitors (SSRIs) commonly prescribed to treat depression and anxiety disorders. The fact that the client has been switched from Zoloft to Paxil suggests a clinical history of depression or another related mood disorder.

At 65 years old, the client falls within a demographic that often experiences depressive symptoms, possibly triggered by age-related life changes, health issues, or losses. The choice of medication indicates that the social worker is dealing with a client who requires pharmacological support for mood stabilization, which aligns closely with the diagnosis of Major Depressive Disorder.

Insomnia Disorder, while it can co-occur with depression, is not primarily treated with SSRIs unless it stems from a depressive condition. Schizoaffective Disorder involves symptoms of both schizophrenia and mood disorder, which would not typically be managed with a straightforward medication switch between SSRIs. Antisocial Personality Disorder is characterized by a disregard for the rights of others and does not generally involve the use of antidepressants as a primary treatment. Thus, the diagnosis of Major Depressive Disorder is the most fitting in this context
