Abstract:
Antisocial Personality Disorder (ASPD) afflicts 3- 4.5% of men and 0.8-1% of women in the general population, with close to equal prevalence rates within ethnic groups (American Psychiatric Association, 2000; Robins & Regier, 1991, as cited in Derefinko & Widiger, 2008). However, few studies have explored whether the assessment tools for ASPD demonstrate measurement equivalence across these equally affected ethnic groups. The International Personality Disorder Examination Screening Questionnaire (IPDE-SQ; Loranger, 1999) is one such assessment tool that is fairly widespread in its use, but its measurement equivalence for specific personality disorders across ethnic groups has rarely been evaluated. This study uses data from the Collaborative Psychiatric Epidemiology Surveys (CPES) to evaluate the factorial validity and measurement equivalence of the IPDE-SQ ASPD items. Results of this study suggest that a single factor solution fits across ethnic groups, possibly indicating that the IPDE-SQ ASPD items have measurement equivalence across ethnic groups.
