The purpose of this study is to examine how Gestalt art therapy affects industrial accident victims' self-efficacy and clinical factors such as anger, anxiety, lack of social support, somatic distress and depress. For the study, 20 victims were preliminarily selected among those who had accidents within two years and who are being treated in an industrial accident specialized hospital named A. Then, half of them were put into the control group and the rest into the experimental group. Finally, 16 subjects who completed post-test were taken to the study. Self-efficacy scale(SES) and multidimensional psychological test(S type) designed to identify the victims' psychological traits were adopted as research tools. Results obtained by these scales were processed with SPSS 12.0. To supplement the quantitative analyses, content analysis was Landscape montage technique(LMT) and observers' reports. The study consisted of 10 sessions of Gestalt art therapy which took place twice a week and each of which was an hour long. The findings pertaining to the analyses were that the therapy increased the victims' self-efficacy and it decreased levels of clinical factors to the significant extent except anger and somatic distress, according to the result of multidimensional psychological test. The study has its limitation in that the number of subjects was not enough to generalize the findings and that the period of the study was too short to verify long-term effect.
