The purpose of this study was to investigate the effects of a Dance Movement Therapy Program on the problem behavior of young children at group homes. For that purpose, the investigators selected total 20 young children at a group home in Seoul, divided them into the experiment(n=10) and control group(n=10), and administered the Korea-Child Behavior Check List(K-CBCL) to them in total 16 sessions with a 60-minute session per week to compare and analyze results. The analysis results were processed with the SPSS Version 23.0 program to obtain mean and standard deviation for all the variables. Frequency analysis was performed along with the Chi-square test, paired-sample t-test, independent-sample t-test, and ANCOVA. The findings led to the following conclusions: First, there was a significant decrease to the overall behavioral problem of internalization and its sub-factors including emotional instability, anxiety/depression, somatization, and withdrawal in the experiment group before and after the experiment. Those findings also point to significant differences in all the sub-factors of internalization between the groups. Secondly, a significant reduction was also observed in the overall behavioral problem of externalization and its sub-factors including surrounding issues and aggressive behavior in the experiment group before and after the experiment. There were also significant differences in all the sub-factors of externalization between the groups. Those findings demonstrate that the Dance Movement Therapy Program had positive effects on the reduction of behavioral problems of internalization and externalization among young children at a group home.
