The purpose of this study was to examine the effect of a fine arts‐horticulture integrated program on the self‐concept and interpersonal relationship of young children with disabilities. For this purpose, this study attempted to answer research questions as follows: first, what effects does the fine arts‐horticulture integrated program have on the formation of self‐concept in young children with disabilities; and second, what effects does the fine arts‐horticulture integrated program have on the formation of interpersonal relationship in young children with disabilities. The subjects of this study were four young children attending a child care center for young children with disabilities in K City including a boy and a girl with brain lesion, and a boy and a girl with spastic diplegia. The program was designed by including activities preferred by young children from fine arts‐horticulture integrated programs used in previous studies, and it was applied through 14 sessions and 40 minutes per session. The effects of the fine arts‐horticulture integrated program were assessed using the KISE Development Scale (Korean Institute for Special Education, 1995). Data were collected through a pretest and posttest on the children’s self‐concept and interpersonal relationship, and from the results of the pretest and posttest were obtained the scores of the two factors and their sub‐factors for each of the children with disabilities, and differences in the scores were analyzed. According to the results of this study, first, self‐concept was significantly higher in the experimental group than in the control group. Second, interpersonal relationship was significantly higher in the experimental group than in the control group. The findings of this study suggest that the fine arts‐horticulture integrated program is effective in improving the self‐concept and interpersonal relationship of young children with disabilities. The meanings and limitations of this study and suggestions for future studies were discussed.
