title: Collateral Report of Psychopathy: Convergent and Divergent Validity of the Psychopathic Personality Inventory-Short Form.
abstract: Psychopathy is a personality syndrome comprised of interpersonal, affective, and behavioral features that has emerged as a correlate of intimate partner violence perpetration. One commonly used self-report measure of psychopathy is the Psychopathic Personality Inventory-Short Form. The current study employed a multi-trait, multi-method approach to test convergent and discriminant validity of the measure in partner-violent couples by comparing males' self-report of psychopathy to the informant report of their female partner (N = 114). It was hypothesized that the female partner-report of the male's psychopathy would be highly correlated with the male report of his own psychopathy, thus providing evidence for the construct validity and interrater reliability of the PPI-SF. Analyses found that male and female reports were correlated significantly on the two major factors of the PPI-SF. Furthermore, the female-report explained a significant amount of variance over and above men's self-report on PAI scales designed to indicate antisocial personality traits.
