Abstract

This study examined the predictive validity of two widely used measures of psychopathic traits, the Psychopathy Checklistβ€”Revised (PCL‐R; Hare, 2003) and the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996). Records of institutional infractions were obtained for a young adult sample of prison inmates (N = 46), who were followed for approximately two years following administration of these two scales. The PPI total and two factor scores predicted the total number of infractions committed (r ranging from .28 to .36). PPI Factor I showed some evidence of stronger associations with non‐aggressive infractions (r = .36), whereas PPI Factor II was the strongest correlate of aggressive misconduct (r = .24). The total and facet scores of the PCL‐R were not significantly predictive of any form of institutional misconduct, with effect sizes ranging from negligible to small (median r = .14, r ranging from βˆ’.01 to .21).

Investigators often report results of studies comparing the proportions of subjects who have clinically meaningful responses to various therapeutic regimens. When the outcome variable is a continuous measure this involves dichotomizing the observed response based on a prede"ned threshold value. The
