이 연구는 특수교사의 주관적 삶의 질 척도 개발을 위한 타당화 예비연구이다. 특수학교, 특수학급, 특수교육지원센터에 근무하는 특수교사 571명의 설문이 연구에 활용되었다. 탐색적 요인분석과 확인적 요인분석을 통하여 타당도와 신뢰도를 검증하였으며, 모형의 적합도를 확인하였다. 연구결과 특수교사의 주관적 삶의 질 척도는 5개요인 18문항일 때 가장 적합한 모형이 되었다.이때 절대적 적합지수인 CMIN/DF=2.43, GIF=.945, RMR=.018, RMSEA=.049로, 중분적합지수인NFI=.905, NNFI=.928, CFI=.941로 간명적합지수인 AGFI=.925, PCFI=.769, PNFI=.739였다. 각요인별 부하량은 .60이상으로 높게 나타났으며, t값이 모두 p<.01에서 유의하여 수렴타당도가 확보되었다고 할 수 있다. AVE(Average Variance Extracted) 값이 r2보다 커서 판별타당도 역시 확인되었다고 할 수 있다. 18개 문항 전체에 대한 Cronbach α는 .833이었다.
This is a validation preliminary study for developing subjective quality of life scale for special education teachers. In this study, we used a survey which was taken by a total of 571 special education teachers from special schools, special classes and special education support centers. Through exploratory factor analysis and confirmatory analysis, we were able to test validity and reliability, as well as confirm a goodness of fit model. According to the test results, scale was decided by 5 factors and 18 questions. The confirmed results of the goodness of fit model: CMIN/DF=2.43, GIF=.945, RMR=.018, RMSEA=.049, showed the absolute goodness of fit index to be positive. The incremental fit index was also positive with its results being: NFI=.905, NNFI=.928, CFI=.941. The incremental fit index was also positive with its results being: AGFI=.925, PCFI=.769, PNFI=.739. The convergence validity was secured as the test statistic t-value, with its high-set standard capacity in each factor (over .60), were all synonymous with p<.01. Discriminatory validity was secured as the AVE(average variance extracted) value was higher than r2; and the construct validity was also confirmed when considering the composite reliability (CR) and AVE. The overall validity regarding the 18 questions was found to be relatively high with Cronbach α being at .833.
