An examination of gender-moderated test bias on the Levenson Self-Report Psychopathy Scale

In this investigation, we examined the validity of Levenson's Self-Report Psychopathy Scale (LSRP; Levenson, Kiehl, & Fitzpatrick, 1995) in a sample of undergraduate students (n = 403). Utilizing a step-down hierarchical multiple regression procedure (e.g., Arbisi, Ben-Porath, & McNulty, 2002), we used LSRP scores to predict psychopathic personality traits to determine the presence of gender-moderated test bias. Results indicate similar correlational magnitudes for men and women. However, systematic over- and underprediction of scores (i.e., differential intercepts) was found for external criteria measuring key affective (i.e., low empathy) and behavioral (i.e., aggression, antisocial behavior) components of the psychopathic personality, although these effects were generally small.
