Antisocial personality disorder (ASPD) is associated with suicide, violence, and risk-taking behavior and can slow response to first-line treatment for Axis I disorders. ASPD may be assessed infrequently because few efficient diagnostic tools are available. This study evaluated 2 promising self-report measures for assessing ASPD--the ASPD scale of the Personality Diagnostic Questionnaire-4 (PDQ-4; S. E. Hyler, 1994) and the Personality Assessment Inventory (PAI; L. Morey, 1991, 2007)--as well as the ASPD module of the Structured Clinical Interview for DSM-IV Axis II (SCID-II; M. B. First, R. L. Spitzer, M. Gibbon, J. B. W. Williams, & L. S. Benjamin, 1997). The measures were administered to 1,345 offenders in court-mandated residential substance abuse treatment programs and prisons. PDQ-4 and PAI scores related strongly to SCID-II symptom counts (rs = .67 and .51, respectively), indicating these measures convey useful clinical information about the severity of offenders' ASPD pathology. The dimensional association between the measures was relatively invariant across gender, race, and site, although differences in mean scores were observed. Levels of agreement of the SCID-II with the PDQ-4 (kappa = .31) and PAI (kappa = .32) in classifying participants as ASPD was limited. Alternative thresholds for both self-report measures were identified and cross-validated.
