The purpose of this research was to examine the effects of using social-supportive group art therapy(SGAT) as a psychological approach to manage public officials’ job stress and organizational commitment. The subjects of this research were 20 city officials in North Chung-Cheong Province, and they were randomly placed in two different groups: half in the control group and half in the experimental group. A pre-test and post-test control group design was used to verify the effects on SGAT to the public officials’ job stress and organizational commitment. SGAT was used with the experiment group for a total of eight sessions, 120 minutes each from October 2017 to December 2017. To measure the effects of SGAT, questions about organizational commitment and from the Korean Occupational Stress Scale(KOSS) were used. The collected data were analyzed by paired t-test. The results were as follows: First, after the SGAT, public officials in the experimental group reported positive differences, but non-significant effects on job stress. Among the causing factors of KOSS, there were significant changes in job demands. Second, SGAT had significant effects on the organizational commitment of public officials, and statistically significant improvements were noticed. Results from this study indicate that art therapy has potential as an intervention for treating public officials’ job stress and improving their organizational commitment.
