Examining the factor structure of the Hare Self-Report Psychopathy Scale.
The 64-item Hare Self-Report Psychopathy Scale (Hare SRP;  Paulhus, Neumann, & Hare, in press ) is the most recent revision of the SRP, which has undergone numerous iterations. Little research has been conducted with this new edition; therefore, the goal of this study was to elucidate the factor structure as well as the criterion-related, convergent, and discriminant validity of the measure in a large sample of college students (N = 602). Confirmatory factor analyses revealed that the best fitting model was the original 4-factor model proposed by the authors of the Hare SRP (compared to a 1-factor, 2-factor, and 4-factor random model). The 4-factor model revealed superior fit for the data relative to the other alternative models. In addition, we elaborated on the psychometric properties of this 4-factor model in this sample. The Hare SRP total and factor scores evidenced good internal reliability as well as promising criterion-related, convergent, and discriminant validity in terms of predicting scores on conceptually relevant external criteria. Implications for theory and future research are discussed.
