본 연구의 목적은 협동 중심 집단미술치료가 발달장애 성인의 사회적 기술에 미치는 효과를 살펴보고자 하였다. 연구의 대상은 K시 복지시설에 거주하는 발달장애 성인 10명으로 실험집단과 통제집단에 각 5명씩 무선배치 하였다. 연구도구는 Gresham과 Elliott(1990)이 개발, 김향지(1996)가 번안 및 수정한 사회적 기술 평정척도를 사용하였다. 프로그램은 2018년 1월 30일부터～2018년 3월 30일까지 주 2회씩 총 14회기 실시되었으며 실험집단과 통제집단간의 동질성 여부를 알아보기 위해 Mann-Whitney U검증을 하였으며 또한 프로그램 효과검증을 위해실험집단과 통제집단의 사전·사후 사회적 기술 점수를 이용해 Wilcoxon 검증을 실시하였다. 연구 결과, 협동 중심 집단미술치료는 발달장애 성인의 사회적 기술 전체에 긍정적인 효과를 미치는 것으로 나타났다. 이상의 연구결과를 통하여 협동 중심 집단미술치료가 발달장애 성인의 사회적 기술향상에 효과적임을 입증하였다는데 그 본 연구의 의의가 있다.

This research sought to explore the effects of cooperation center collective art treatment on the social skills of underdeveloped adults. The subjects of the research are underdeveloped adults living in K City Welfare Facilities, and five of them were assigned to control groups of five. Cooperative center collective art treatment programs from January 30, 2018 to March 30, 2018. Content is divided into initial, intermediate, and closing phases. The initial stage creates intimacy and interest, and the first stage in the mid-term introduce self-assertion and cooperation. Phase 2 improves self-assertion and cooperation, and stage 3 improves self-assertion, cooperation and self-control. The closing phase was carried out through the continuation of the technology through the work. The research tools of this research were developed by Gresham and Elliot(1990) and translated and modified by Kim Hyang-ji(1996) is Social Skill Rating System(SSRS) nonparametric validation was used because it was difficult to satisfy the assumptions about the distribution of a population with 5 cases per group. Manny-Whitney U verification was conducted to determine the homogeneity of the social technology measures of the experimental and controlled groups The total mean and standard deviation of the social technology measures and the mean and standard deviation of the subfactory. Also Wilcoxon's was also conducted for each group. The results of this study show that cooperation center collective art therapy has a positive effect on the overall social skills of adults with developmental disabilities. It is meaningful that the results of the above study showed that cooperation center collective art therapy was effective in improving social skills of adults with developmental disabilities.
