Abstract

The aim of the present study was to investigate the reliability and validity of the Comprehensive Assessment of Psychopathic Personality-Institutional Rating Scale(CAPP-IRS) in Korea. Eighty nine inmates at correctional prisons across provinces participated in the study. We compared the CAPP-IRS’ psychometric properties to those of the Psychopathy Checklist-Revised(PCL-R) and Psychopathic Personality Inventory-Revised(PPI-R). As a result, the CAPP-IRS showed good to excellent interrater reliability and good test-restest reliability. The CAPP-IRS also showed overall good associations with interview-based PCL-R and self-reporting based PPI-R, which means good concurrent validity. Our findings suggest that the CAP-IRS approved clinical utility for the assessment, diagnosis, and intervention in Korea.
