본 연구는 첫째, 생활체육에 참여하는 노인의 사회적 지지 척도를 다집단(multi-group) 확인적 요인분석을 통한 구인동등성(형태 동일성, 측정 동일성, 절편 동일성)을 검증함으로서 남자와 여자 노인에게 사회적 지지 척도가 공통적으로 적용될 수 있는가를 검토하고 둘째, 잠재평균분석을 통하여 사회적 지지의 2요인(정서적 지지, 물질적 지지)에 대한 남자와 여자 노인집단 간의 잠재평균차이를 검증하는 데 그 목적이 있다. 연구대상은 서울시와 경기도에서 생활체육교실, 생활체육동호회에 참여하고 있는 만 65세 이상 노인을 모집단으로 설정한 후 각 기관 및 단체에 직접 방문하여 유목적 표집법을 이용하여 298명의 자료를 수집하였다. 본 연구에서 생활체육에 참여하는 노인을 대상으로 사회적지지 척도의 성별에 따른 구인동등성과 잠재평균분석을 실시한 결과 다음과 같은 결론을 얻었다. 첫째, 생활체육에 참여하는 남녀 노인의 사회적 지지 척도에 대한 다집단 확인적 요인분석을 실시한 결과, 형태 동일성, 측정 동일성, 절편 동일성이 모두 충족되어 구인동등성이 검증된 것으로 나타났다. 즉, 남녀 노인의 각 잠재변수와 측정변수들이 사회적 지지 척도에 동일하게 적용되었음을 의미하므로, 잠재요인의 차이점수를 집단별로 비교하는 것이 가능하였다. 둘째, 잠재평균분석 결과, 사회적 지지의 요인 중 물질적 지지의 집단 간 평균차이가 통계적으로 유의미하게 나타났으며, 남자 노인의 잠재 평균이 여자 노인집단 보다 높게 나타났다. 아울러 잠재평균차이의 효과크기를 살펴보면 정서적 지지가 .264, 물질적 지지가 .613으로 나타나 Cohen이 제시한 기준에 의거하여 중간수준의 효과크기로 나타났다. The following were the purpose of this study. First, whether social support construct change of factor pattern with the males and females; testing configural, metric, scalar invariance.
