This study was conducted to investigate the effect of group art therapy using cognitive behavioral theory on anger control, perceived stress, and problem-solving skills in inpatients with alcohol use disorder. The participants were inpatients at a private psychiatric hospital located in S city, and of these inpatients who were diagnosed with alcohol use disorder, 14 were randomly sampled. Then, they were divided into 7 in experimental groups and 7 in control groups. Utilized research criteria were a Korean version of a State-Trait Anger Expression Inventory, Perceived Stress Scale, and a drawing test named a Person Picking an Apple from a Tree(PPAT). In addition, to prove the effectiveness of the treatment, a preliminary test was conducted before the treatment and a follow-up test was conducted after the treatment. As a result, first, the sub-category of anger expression in the state-trait anger expression inventory, anger control item showed a statistically significant increase. Second, the perceived stress showed a statistically significant decrease. Third, among the 14 items of FEATS of the PPAT test, the logic, problem solving, and line quality sections revealed a statistically meaningful improvement. This study shows a possibility that the group art therapy using cognitive behavior theory is effective for anger control improvement, perceived decrease in stress, and changing problem-solving skills for inpatients with alcohol use disorder. In addition, this study is significant in the way that the PPAT test can be effectively used for alcohol use disorder patients.
