title: The incremental validity of passive-aggressive personality symptoms rivals or exceeds that of other personality symptoms in suicidal outpatients.
abstract: We examined the incremental validity of passive-aggressive and other personality symptoms, by determining personality syndromes' ability to account for unique variance in distress and impairment as indexed by several Axis I-related symptoms. Two hundred fifty young adults, referred for suicidal behavior or ideation, completed the Millon Clinical Multiaxial Inventory (Millon, 1983) as well as several other symptom measures. The personality syndromes varied considerably in their ability to account for unique variance in Axis I-related symptoms. Several syndromes, including schizoid, schizotypal, and compulsive symptoms, showed relatively low incremental validity, whereas the incremental validity of passive-aggressive symptoms exceeded all others. The criterion of incremental validity represents an inclusive and persuasive means to evaluate personality disorder validity. On this criterion, passive-aggressive symptoms display high validity, and passive-aggressive personality disorder, in some form, may deserve inclusion on Axis II of future editions of Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association).
