Validation of recidivism risk assessment for mentally disordered offenders

본 연구의 목적은 정신장애 범죄자의 재범위험성을 평가하는 도구의 타당도를 검증하여 추후 한국형 정신장애 재범위험성 평가도구를 개발하기 위한 것이다. 본 연구에서는 국립법무병원에 입소된 정신장애 범죄자를 대상으로 하여 초범이면서 신규 입소한 집단과 2회 이상의 재범으로 재입소를 한 집단으로 나눈 뒤, 그들의 공식기록 및 선행 연구 검토를 통해서 미리 구성한 반구조화된 질문에 따른 체계적이고 심층적인 면담을 통해 외국에서 활용도가 높은 재범위험성 평가도구들(LSI-R, HCR-20, VRAG)의 신뢰도와 타당도를 검증하였다. 내적합치도 Cronbach α는 LSI-R .81, HCR-20 .71, VRAG .60이었고, 평가자간 신뢰도는 .78에서 1.00의 범위였다. 각 평가도구의 총점 및 각 하위 요인별 상관을 제시하였다. 그리고 ROC 분석을 통하여 각 평가도구의 예측력과 예측 진단 기준점을 산출하였다. 초범/첫입소 집단과 재범/재입소 집단간에 유의한 차이를 보였던 인구통계학적 변인과 4개의 재범위험성 관련 요인을 토대로 하는 후속 연구를 통하여 우리나라 정신장애 범죄자의 재범 위험에 대한 객관적이고 타당성 있는 평가가 가능할 것으로 기대하며, 본 연구의 제한점과 후속 연구의 방향을 제시하였다.

Abstract

The purpose of this study is to verify the validity of assessment tools to evaluate the risk of recidivism for mentally disordered offenders. The subjects of our study are mentally disordered offenders admitted to the National Forensic Hospital, and we used their official records in order to create a well-organized and in-depth interview based on semi-structured questionnaires. By reviewing previous research, this study identified the reliability and validity of recidivism risk assessment tools (LSI-R, HCR-20, VRAG), which had been widely used in other countries. Cronbach's α of internal consistency in the results of this study were shown as followed: LSI-R .81, HCR-20 .71, VRAG .60. Additionally, the inter-rater reliability ranged from ICC .78 to 1.00. The correlations of each assessment's total score and factors were presented in this study. By analyzing ROC, we found the predicting power and cut-off score of each assessment tool. We expect that we can estimate and predict, objectively and reasonably, the recidivism risk of mentally disordered offenders by conducting a follow-up study, which would focus on demographic factors and four other recidivism-related factors which had shown significant differences between high-risk groups and low-risk groups. We also discussed the limitations of this study and the direction of follow-up research.
