The purpose of this study was to identify the effects of art therapy for reducing anxiety and aggression in an emotionally neglected child. The subject of the study was 8-year-old elementary school-aged girl. The study period lasted from September 27, 2018, to March 8, 2019, and the art therapy program for the subject consisted of 28 total sessions, one to two times per week for 60 minutes per session. The measurement tool used was the Toronto Alexithymia Scale(TAS), for which the anxiety scale for adults by Speilberger(1972) has been edited for children to ensure an easy understanding of the scale. In addition, the aggression scale from the Hostility Inventory by Buss and Durkee(1957) has been was adapted to reflect the Noh An Ryung of South Korea to be used. Finally, the Home-Tree-Man picture examination was administered. Based on these measures, the results were as follows: First, art therapy affected the emotionally neglected child s level of anxiety. The anxiety related to the pre-test was quite high, but returned to a normal level post treatment. In addition, the child s level of anxiety remained normal during the follow-up tests. Second, the art therapy affected the emotionally neglected child s level of aggression. In addition, all sub-domains of aggression, - physical aggression, verbal aggression, bypass aggression, negativity and excitation - were also shown to have postmortem effects greater than dictionary definitions, indicating long-term persistence. These findings indicate that art therapy can affect emotionally neglected children s anxiety and aggression.
