Abstract: | The Levenson Self-Report Psychopathy Scale (LSRP) is a promising, efficient measure of the psychopathic personality. Previous
examinations of its latent structure have yielded inconsistent results; therefore, the goal of the current study was to evaluate
previously reported two- and three-factor models in three separate groups of male correctional inmates (n = 573), male college students (n = 202), and female college students (n = 200). Confirmatory factor analyses revealed that the best-fitting model across all the three groups was the three-factor
model proposed by Brinkley et al. (Assessment 15:464–482, 2008). The convergent and discriminant validity of this three-factor structure as well as a revised 19-item total score were elaborated
on in terms of predicting scores on conceptually relevant external criteria. The LSRP total and factor scales evidenced good
convergent and discriminant validity with a few notable exceptions. Implications for theory and future research are discussed. |
