This study investigated the effects of group art therapy using logotherapy on the daily stress of middle school students and their sense of the meaning of life. Senior students at a middle school in C city received a daily stress level test and the meaning of life test, whose daily stress scores above the average and their scores of meaning of life below the average were selected. Among them 16 students were divided into an experimental group of 8 and a control group of 8. and they received a group art therapy program. The program which ran 9 sessions, once a week, each session 90 minutes long. The instruments including an adolescent stress scale and the meaning of life scale were administered to the experimental group before and after the group art therapy program. The data was analyzed by conducting A Mann-Whitney U test to check the homogeneity between the groups. A Wilcoxon signed-rank test was conducted to check the effects of the program. The findings of this study are as follows. First, group art therapy using logotherapy did not yield statistical significance on the daily stress. However, the PITR results showed a partial reduction in the stress. Second, group art therapy using logotherapy showed significant differences in the meaning of life, proving the positive effects of the program on improving the participants' sense of the meaning of life. Third, as the therapy program progressed, the participants were seen identifying and dealing with their stress positively, became purpose-oriented realizing the preciousness of people and their lives, and made voluntary efforts to make changes, all of which were indications of an improvement in their sense of the meaning of life. These findings suggest that group art therapy using logotherapy was partially effective in reducing the stress and in improving the meaning of life.
