Abstract

The Expanded–Levenson Self-Report Psychopathy Scale (E-LSRP) was developed by Christian and Sellbom to improve on the psychometric properties of scores on the Levenson Self-Report Psychopathy Scale. The current study investigated the construct validity of scores on the E-LSRP in 393 male inmates. Results provided support for the reliability and construct validity of E-LSRP scores. Specifically, confirmatory factor analysis results demonstrated support for a three-factor model. Additionally, correlation and multiple regression results provided evidence supporting the convergent and discriminant validity of E-LSRP scores against scores on measures assessing psychopathy-related personality traits (e.g., antagonism, disinhibition) and symptoms of internalizing disorders, respectively. Overall, these findings extend those of previous research by establishing that E-LSRP scores demonstrate validity in assessing psychopathy in correctional settings and thus, may be a useful tool for the assessment of psychopathy in these settings.
