The General Criteria for Personality Disorders Assessed by Interview: Do They Still Have a Role to Play?

On the path to developing dimensional models of personality disorder (PD), we are at risk of leaving key diagnostic aspects behind. The general criteria for PD may be important ones because they reflect the defining aspects of personality pathology: long duration, independence from psychopathological states, and harmfulness. We assessed these criteria by interview in a sample of 362 psychiatric outpatients after administering the Personality Diagnostic Questionnaire-4+.

Personality Disorders Are Not as We Thought: Hierarchical Factor Structure at the Criterion Level.

The use of personality disorder (PD) categories persists, despite the evidence against them. An often overlooked reason for this is the fact that the true structure underlying the Diagnostic and Statistical Manual of Mental Disorders (DSM) taxonomy is still unknown: We cannot be certain which disorders are valid, and which ones are arbitrary mixtures of heterogeneous traits. To address this gap, we factor analyzed the Personality Diagnostic Questionnaire (PDQ-4+; Hyler, 1994 ) at the criterion level in a mixed clinical and nonclinical sample of 2,519 individuals.
