Comparisons of voluntary and involuntary admissions have found that the primary diagnosis for most voluntary patients is:

A) anxiety disorder.
B) dissociative disorder.
C) depressive disorder.
D) personality disorder.
E) psychotic disorder.

Research studies have consistently found that depressive disorder is the most common primary diagnosis among voluntary psychiatric patients. This may be due to the fact that individuals experiencing depression are more likely to be aware of their symptoms and seek treatment on their own. In contrast, involuntary admissions are more frequently associated with psychotic disorders, substance use disorders, and other conditions that involve a loss of insight or awareness.
