한국판 성격평가질문지의 요인 구조

Factor Structure of the Korean Personality Assessment Inventory (PAI)

성격평가질문지(Personality Assessment Inventory; PAI)는 성격 및 정신병리를 측정하기 위한 자기보고식 설문지로, 심리적 증상 뿐만 아니라 대인관계 문제, 치료에 대한 태도, 공격성 등 임상 장면에서 중요한 정보를 제공한다는 강점이 있다. PAI의 임상적 유용성이 증가됨에 따라 PAI의 요인 구조를 확인하기 위한 연구도 이루어져 왔다. 그러나 연구마다 표본이나 분석 방법의 차이로 인해 요인의 개수나 속성에 있어서 차이가 보고되었으며, 비일관적인 결과가 존재한다. 본 연구에서는 재표준화된 한국판 PAI의 성인 표준화집단을 대상으로 PAI 전체 척도의 요인 구조를 확인하였다. PAI의 22개 척도에 대해 평행 분석과 탐색적 요인 분석을 실시한 결과, (1) 전반적인 심리적 불편감, (2) 약물관련 문제, (3) 행동화 경향 및 대인관계 문제의 3요인 구조를 갖는 것으로 나타났으나 적합도가 좋지못한 것으로 나타났다.

The Personality Assessment Inventory (PAI) is one of the most widely used self-report measures that assess personality and psychopathology. The psychometric properties of the PAI were broadly investigated including its reliability and validity. Previous literature that explored the factor structure of the PAI has revealed inconsistent results. The factor structures found in the previous studies were different in the number of factors or components, which results from the characteristics of the sample and methodological issues. The present study aimed to explore the factor structure of the revised version of the Korean PAI through exploratory and confirmatory factor analyses. The total sample comprised 1,279 Korean adults collected from the project to develop the restandardized Korean version of the PAI. The revised version of the Korean PAI was administered in Korean adult population. Parallel analysis revealed that a 3-factor solution is appropriate for 22 PAI full scales. The result of exploratory factor analysis generated 3 oblique dimensions, which consist of (a) general psychological distress, (b) drug-related problem (c) tendency to act out and interpersonal problem. However, the fit indices of confirmatory factor analysis were poor. The components of the 3-factor structure are generally in line with the results of previous literature except the component representing drug-related problem. Our findings provided support to the applicability of the restandardized version of the PAI in the Korean population and contributed to enhancing confidence regarding the construct validity of the PAI.
