The Hare Self-Report Psychopathy Scale is a promising self-report inventory primarily designed for the assessment of psychopathic traits in non-forensic populations. Since its development, the instrument has undergone several substantial modifications. Factor analytical and validity studies on the two most recent versions, i.e. the 64- (Self-Report Psychopathy Scale III; Paulhus, Neumann, & Hare, in press) and the 28-item version (Self-Report Psychopathy Scale 4 Short Form; Paulhus, Neumann, & Hare, in press), is still limited. The current study aimed to evaluate the factor structure and to elaborate the external validity of both versions in a large community sample (N=1505). Results supported the factor structure of both SRP-versions consisting of the four factors Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Criminal Tendencies. Furthermore, both SRP-versions exhibited good external validity in relation to a wide range of theoretically relevant correlates (e.g. avoidant attachment style, bullying behavior, aggression, and extremist, antisocial attitudes). Notwithstanding, differences between the two SRP-versions with regard to their relations with external correlates were found. |
