Psychopathy has emerged as one of the most important criminal figures in the criminal justice system and criminological psychology in Korea. One reason for the surge is the need to predict criminal recidivism. Many studies have shown psychopathic traits-callousness, impulsivity, irresponsibility, lack of empathy, guilt, or remorse, and so forth-are closely related to criminal behaviors and recidivism. The PCL-R: Korean Version was accomplished the standardization by Eunkyung Jo and Soo Jung Lee in 2008. This study conducted the construct validation study of the PCL-R: Korean Version. As the result of the study, first, the PCL-R: Korean Version had significant positive correlation with Static-99(r=.48, p<.01) and MnSOST-R(r=.55, p<.01), sex offender risk assessment scales. Second, the PCL-R score significantly correlated with the total number of criminal records, the first arrest age and correctional officials' assessment of offenders. Third, follow-up prediction study by tracing recidivism was conducted to produce the optimal cutoff-score. The PCL-R score had significant positive correlation with the recidivism of the subjects. The present study identified new cutoff-score based on whether reoffending or not after release. As the result of ROC analysis, the score of 26 as an optimal cutoff-score had the highest accuracy(71.5%), sensitivity .61 and specificity .74. Finally, using the confirmatory analysis, it was yielded that 4-factor models of the PCL-R: Korean Version fitted to the current data. Therefore, we concluded that the ability of the PCL-R: Korean Version to predict recidivism is considerable, so we proposed that this assessment tool apply to Korean criminal justice system.
