The utility of the Psychopathy Checklist-Revised (PCL-R) facet and item scores in predicting violent recidivism.

There is relatively limited research on psychopathy in non-Caucasian ethnic groups and even less on the utility of the Psychopathy Checklist-Revised (PCL-R) that focuses on PCL-R facet and item scores in predicting violent recidivism. In this study, we assessed the utility of the PCL-R in prospectively predicting violent versus nonviolent recidivism during an 11-year follow-up window. A high-risk sample of 451 incarcerated Korean male offenders was assessed on the PCL-R at baseline. A total of 445 were reconvicted after release (353 violent and 92 nonviolent recidivists). Psychopathy facet scores were higher in violent compared to nonviolent recidivists. Facet 2 (affective) showed the strongest effect size (Cohen's d = 0.53; Percentage change in odds = 22.6%) in predicting violent recidivism. Analyses of the four items constituting the affective facet indicated that callous/lack of empathy (Percentage change in odds = 134.4%) and failure to accept responsibility (Percentage change in odds = 94.5%) were the strongest predictors of violent recidivism. Findings are to our knowledge the first to document the utility of the PCL-R in distinguishing violent from nonviolent recidivism and highlight the role of affective impairment (particularly lack of empathy) in violent recidivism.

Interpersonal and Affective Facets and Items of the Psychopathy Checklist-Revised (PCL-R) in Predicting Child Sex Offending.

Psychopathy of child sex offenders in non-Western and Asian population is not frequently reported. The study examined psychopathic traits assessed by the Psychopathy Checklist-Revised (PCL-R) in three groups of male offenders, child sex offender, adult sex offender, and nonsex offender groups. Out of 451 offenders included in the sample, 445 recidivated after a follow up of 11 years: 27 child sex offenders, 174 adult sex offenders, and 244 nonsex offenders. Adult sex offenders scored higher in four facets and total scores compared with nonsex offenders. Child sex offenders had more problems in interpersonal (facet 1) and affective (facet 2) traits than nonsex offenders. More specifically, child sex offenders scored higher in failure to accept responsibility (item 16, Cohen's d = 0.80) and callous/lack of empathy (item 8, Cohen's d = 0.59) of facet 2 and pathological lying (item 4, Cohen's d = 0.58) and glibness/superficial charm (item 1, Cohen's d = 0.48) of facet 1 than nonsex offenders. Both child sex offenders and adults sex offenders were found to be more psychopathic than nonsex offenders. While facets 1, 2, and 3 did not separate child and adult sex offending, child sex offenders scored significantly lower in antisocial problems (facet 4) than adult sex offenders. Despite the limitation of using a sample of mostly high-risk offenders, our findings indicate that higher PCL-R scores in specific facets (1 and 2) and items (1, 4, 8, and 16) are more predictive of child sex offending and suggest insight for treatment strategies of child sex offenders.

Investigating Two-, Three-, and Four-Factor Structures of the Korean PCL-R in Serious Offenders.

There is no published work on different factor structures of the Psychopathy Checklist-Revised (PCL-R) for Korean offenders. The current study compared the two-, three-, and four-factor structures of the Korean version of the PCL-R. A total of 451 adult male serious offenders were included. The results suggested that both three- and four-factor models offered the best overall fit to the data. To gain better insight into the construct and predictive validities of the Korean version of the PCL-R, we recommend further analysis of the three- and four-factor models with recidivism and inmates' implicit aggression levels.
