The relations between the Psychopathic Personality Inventory (PPI; Lilienfeld and Andrews, 1996) and 4 theoretically related constructs (empathy, aggression, work ethic, and borderline personality disorder) were examined. Additionally, the relation between the PPI and heroism was explored. One hundred male inmates were administered the PPI, the Questionnaire Measure of Emotional Empathy (Mehrabian and Epstein, 1972), the Aggression Questionnaire (Buss and Perry, 1992), the Protestant Ethic Scale (Mirels and Garrett, 1971), the Self-Report for Borderline Personality Scale (Oldham et al., 1985), and the Activity Frequency Inventory (Lilienfeld, 1998). As predicted, the PPI was significantly negatively correlated with empathy and significantly positively related to aggression and borderline personality. Contrary to prediction, the correlation between the PPI and work ethic was not significant. Eight of 11 hypotheses regarding the relations of the PPI subscales to these 4 constructs were corroborated. Results support the construct validity of the PPI in a correctional sample. The exploratory analysis of the relation between the PPI and heroism revealed no significant relations.
