체육학연구에서 확인적 요인분석 이용의 문제점과 올바른 적용

국문 초록 (Abstract)

본 논문은 tutorial 성격의 논문으로서 연구의 목적은 체육.스포츠 분야의 연구에서 흔히 사용되고 있는 요인분석 법의 적용 시 나타나는 문제점들을 고찰하고 이들에 대한 바람직한 해결방안과 요인분석의 올바른 적용 방법을 제시 하는 것이다. 스포츠심리학, 스포츠사회학, 스포츠경영학, 스포츠여가학 등에서 가장 빈번하게 사용되고 있는 자료 분 석법인 요인분석은 잘못 적용되거나 부분적으로 문제점을 가진 경우가 많다. 연구자들이 요인분석을 자료 분석에 적용 할 때 가장 흔히 겪는 문제점은 확인적 요인분석과 탐색적 요인분석의 선택, 자료의 비정규성, 측정척도 문제, 표본의 크기, 모형의 적합도 평가 시 적합도 지수 선택과 기준 등이다. 이 외에도 요인분석법 자체에 대한 이해 부족에서 오 는 적용의 오류 등도 있다. 본 논문에서는 이와 같은 문제점들을 고찰, 정리하고 이에 대한 해결방안을 제시하였다. 요 인분석법은 수학적, 통계적으로 매우 복잡한 방법으로 적용 시 많은 요소들을 고려해야 하며 올바른 이해를 바탕으로 한 올바른 적용이 필요하다.

다국어 초록 (Multilingual Abstract)

This is a tutorial paper on the appropriate understanding and usage of factor analysis model in applied physical education and exercise science research. This paper discusses several issues that one may encounter in using factor analysis model in an applied research. Discussed issues include selection between an exploratory factor analysis and a confirmatory factor analysis model, non-normality of data, analyzing ordinal scale data, sample size, model evaluation with goodness-of-fit indexes and its criteria. This paper discussed these issues based on literature review, small simulation examination and authors` experience as statistical consultants and as reviewer of many research journals. Factor analysis model and analysis is a very complex technique which requires a high level knowledge and experience. Researchers need to understand these common issues and apply this statistical model with caution.
