청소년 정신병질 특성 척도 타당화 = A Validation Study of The Youth Psychopathic Traits Inventory: YPI

다국어 초록 (Multilingual Abstract)

The present study attempted to validate the Korean version of the Youth Psychopathic traits Inventory (YPI) that have originally been developed by Andershed, Kerr, Stattin, & Levander (2002). The YPI has 50 items measuring the three facets of psychopathic traits among the general population of adolescents. It has been reported that the YPI has adequate level of internal consistency (α=.88) and moderately related with the occurrence of various deviant behaviors. For the present study, the original English version YPI was translated into Korean. This Korean version YPI was administered to 749 Korean adolescents (Mean age = 16.71) sampled from Seoul and Pusan metropolitan areas. The major findings were that (1) the reliability was adequate (internal consistency coefficient = .88), (2) three factors (interpersonal, affective, behavioral) were extracted as expected, (3) the cluster analysis identified the psychopathy-like group, and (4) the clustered psychopathy-like group demonstrated the expected pattern of scores on the three criterion measures (Narcissistic Personality Scale, Socialization Scale, M-C social desirability scale). In general, these findings suggest that the Korean version YPI is a reliable and valid measure of psychopathy-like traits among the general population of Korean adolescents and, thus, be utilized in the future studies. However, it was highlighted that the results should be interpreted cautiously because the reliability coefficients of the three subscales of Korean version YPI were unacceptably low. In addition, the ethical problems of using the YPI as a decision-making tool for a youth was discussed.

국문 초록 (Abstract)

본 연구는 일반 청소년들 집단에서 나타나는 정신병질적 특성을 알아보기 위해 개발된 청소년 정신병질 특성 척도(Youth Psychopathic traits Inventory: YPI)를 한국어로 번안하여 그 타당성을 검증해 보고자 하였다. 이를 위해 서울․경기 지역 및 부산에 거주하는 749명의 청소년들에게 한국어판 YPI를 실시하고 신뢰도 및 타당도를 검증하였다. 그 결과 YPI의 전체 신뢰도는 α=.88로 나타났으며, 세 요인들의 신뢰도는 .69 ～ .87로 Andershed 등 (2002)이 보고한 것과 유사하였다. 또한, YPI가 측정하고 있는 구인들을 확인하기 위해 요인분석을 실시한 결과, 이론적으로 예언된 세 요인의 존재를 확인할 수 있었다. 다음 단계로, 추출된 요인들에 대한 점수를 토대로 청소년들이 정신병질적 특성을 지닌 집단, 정신병질적 특성을 소유하고 있지는 않지만 비행행동경향이 높은 집단 (행동집단), 그리고 정상집단으로 분류될 수 있는지를 보기 위하여 군집분석을 실시하였다. 그 결과, 남자 청소년의 경우 7개의 군집이 그리고 여자 청소년의 경우 8개의 군집이 확인되었다. 이 군집들 중 YPI 세 요인 모두에서 높은 점수를 받은 청소년들이 정신병질적 특성을 지닌 집단으로 정의되었다. 이 집단이 이론적으로 예언된 특성을 중심으로 비행행동 집단 및 정상집단과 차이를 보이는지를 검증하기 위해 일원변량분석을 실시하였다. 그 결과, 정신병질적 집단은 자기애적 성향이 높고, 사회적으로 인정받는 방식으로 자신을 표현하는데 대한 관심이 낮으며, 일탈적 행동 경향성이 높은 것으로 나타났다. 이 같은 결과는 YPI가 일반 청소년들에게 나타날 수 있는 정신병질적 특성을 측정하는 도구로 활용될 수 있음을 시사한다. 그러나, YPI내의 10개의 하위척도들 중 3개는 신뢰도가 지나치게 낮게 나타나 그 사용에 주의를 기울여야 할 것으로 나타났다. 마지막으로, 앞으로의 추가적 연구를 위한 방향 및 이 연구의 제한점이 논의되었다.
