The purpose of this study is to examine the effect of solution-focused group art therapy on self-esteem and sociality for children of low-income single-parent families. To this end, 10 children from low-income single-parent families were randomly assigned to experimental groups and comparative groups and conducted 10 times a week for a total of 90 minutes. Results of the study, first, solution-focused group art therapy had a positive effect on self-esteem and social skills of children from low-income single-parent families.Second, the treatment effect of experimental groups that conducted solution-focused group art therapy was higher than that of comparative groups that conducted collective art therapy. This study is meaningful in that it established solution-focused goals in consultation with group members, subdivided them into common tasks and individual tasks, and achieved results that exceeded the effects of existing group art treatments by doing solution-focused art activities such as miracle pictures. Therefore, we hope that this study will be used as an effective program in schools and institutions.
