The clinical utility of the MMPI-2 Antisocial Practices Content Scale

This study explored the ability of the MMPI-2 Antisocial Practices Content Scale (ASP) to correctly classify DSM-IV Antisocial Personality Disorder (A PD), ASP scores and scores on the MMPI-2 Psychopathic Deviate (Pd) scale we re compared in an APD group (n = 10), a Borderline Personality Disorder gro up (n = 16), a Narcissistic Personality Disorder group (n = 9), an Other Pe rsonality Disorder group (representing personality disorders from Clusters A and C; n = 14), and a nonclinical population (NC; n = 67), The ASP exhibi ted an ability to differentiate APD from other personality disorders and wa s significantly correlated to DSM-TV diagnostic criteria for APD while the Pd was not. Diagnostic efficiency statistics (sensitivity, specificity, pos itive predictive power, negative predictive power, overall correct classifi cation rate, and kappa) were calculated under four different conditions in a clinically relevant manner (Kessel & Zimmerman, 1993, Psychological Asses sment, 53, 395-399). The results of this study illustrate the usefulness of the ASP as a tool for the assessment of antisocial attitudes, beliefs, and behaviors in individuals suspected of having APD. This information may be valuable to clinicians who are planning treatment or assessing treatment ou tcome for clients with APD.
