Online version of the Personality Diagnostic Questionnaire (PDQ-4), a self-report screening measure assessing traits and symptoms associated with personality disorders. Based on DSM-IV diagnostic criteria, it evaluates features of multiple personality disorders and is commonly used as a screening instrument rather than a standalone diagnostic tool.
The PDQ-4 is intended as a screening instrument and tends to overidentify personality disorder features; positive findings should be confirmed through a clinical interview.
