The purpose of this study was to determine the effects of group art therapy on the career stress and career decision level of university students. The participants of the study compromised a total 12 male and female students in their third to fourth year of a university located in A city. They were concerned about career stress and agreed to participate in the art therapy program. They were randomly assigned to an experimental group and a control group with six members in each. The participants in the experimental group underwent 80-minute of 12 art therapy once or twice a week, from January 29, 2019 to March 29, 2019, for a total of 12 sessions. I examined the output of pre-test and post-test quantitative analysis the Career Stress Scale, Person-In-The- Rain Test and Career Decision Level Scale. The data were analyzed by applying the Mann-Whitney U test and Wilcoxon signed ranks test. First, the group art therapy had statistically significant effects on changes in the career stress of the experimental group. Second, the group art therapy had statistically significant effects on changes in the career decision level of the experimental group. Last, in the process of each program stage, the participants in the experimental group explored and expressed their emotions about their careers. Also, they found their own answers about their careers. Therefore, this study is meaningful in that it demonstrated the efficacy of art therapy in decreasing career stress and improving career decision level for university students.
