Answer:
The correct answer is D. He should not make any diagnosis at all, since no condition in DSM-5 is satisfied by this clinical case.
Explanation:
Let's discard one by one.
Option A.
He should create a new diagnosis and inform the authors of the DSM-5.
Why not: Diagnostic labels cannot be created from one particular case. A psychiatrist or clinical psychologist is not entitled to create or formulate a personality disorder just because he/she feels like it.
Option B.
He should diagnose the client with Unspecified Personality Disorder (UPD)
Why not: In the DSM-5 the diagnosis of unspecified personality disorder is made only to enhance the specificity of an existing personality disorder.
Option C.
He should diagnose a different condition such as depression or anxiety as a "place holder" until the true nature of the personality problems is more fully understood.
Why not: T<u>his course of action is not ethical. Clinicians must not misdiagnose patients just because they feel like it. Diagnosing a patient with depression or anxiety without them falling within the diagnostic criteria is medical negligence. </u>
In conclusion, the correct answer is D. He should not make any diagnosis at all, since no condition in DSM-5 is satisfied by this clinical case.
