구조방정식 모형을 이용한 집단 간 요인구조 비교성 검증

초록

The purpose of this study is to introduce the basic concepts associated with multi-group factor analysis and testing for factorial validity and invariance between paper and computer job aptitude battery developed by Ministry of Labor by using structural equation modeling. The three testing methods examined were: configural invariance, metric invariance, scalar invariance testing. The first test was made for configural invariance, based on the assumption that similar factor structure would be existing for the two groups. The result shows that job aptitude battery has the same factor configuration between paper and computer test. The next step was to test full metric invariance by constraining the factor loadings to be invariant between paper and computer test and result show that full metric invariance was estabilished. Full scalar invariance testing was also conducted to illuminate measurement intercepts are equal for the two groups and suggestions were made for further studies.
