This study explored psychopathic personality traits among a non-criminal, college undergraduate sample. Much research has been done on conceptualizing the construct of psychopathy, but this work has been conducted primarily with incarcerated individuals using a structured interview, The Psychopathy Checklist – Revised (PCL-R; Hare, 1991, 2003). The goal of the current study was to assess psychopathic traits among non-criminal individuals using The Self-Report Psychopathy Scale - Version Four (SRP-IV; Paulhus, Neumann, & Hare, in press), and compare how SRP-IV scores were associated with a well recognized semi-structured interview for psychopathy, The Psychopathy Checklist – Screening Version (PCL: SV; Hart, Cox, & Hare, 1995). The study also examined whether psychopathic personality traits could be predicted using a measure of normal-range personality, based on the five-factor model (FFM; Digman, 1990), and a measure developed by Loevinger (1976) related to ego development. Five-Factor Model Rating Form (FFMRF; Mullins-Sweat, Jamerson, Samuel, Olson, & Widiger, 2006) scores and Total Protocol Ratings (TPR score) on the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) were used to predict psychopathy scores. Correlations of SRP-IV scores and PCL: SV scores with FFMRF scores and WUSCT TPR scores were also examined for their uniformity. As predicted, there were significant, negative correlations between FFM domains, Agreeableness and Conscientious, and SRP-IV scores, as well as significant, negative correlations between WUSCT TPR scores and SRP-IV scores. These correlations ranged from small to strong for both SRP-IV overall scores and for SRP-IV factor scores (i.e., Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Criminal Tendencies). Additionally, FFM domain scores and WUSCT TPR scores significantly predicted SRP-IV scores. FFM domains, Agreeableness and Conscientiousness, and WUSCT TPR scores, were the strongest predictors of SRP-IV scores. Similar results were found when FFM domain scores and WUSCT TPR scores predicted SRP-IV factor scores. Results also indicated Agreeableness and Conscientious explained an additional 24% of the variance in psychopathy scores, after controlling for WUSCT TPR scores. Conversely, WUSCT TPR scores explained an additional 5% of the variance in psychopathy scores after controlling for Agreeableness and Conscientiousness. Finally, as predicted, the differences in correlations between psychopathy scores (i.e., PCL: SV, SRP-IV), and Agreeableness, Conscientiousness, and WUSCT TPR scores were not statistically significant providing evidence that correlates of psychopathic traits can be measured among non-criminal individuals using a self-report measure, the SRP-IV, and that these findings are concordant with those based on a standardized structured assessment for psychopathy. Limitations of the study, implications, and recommendations for future research are also discussed.
