The purpose of this study was to examine the effects of a group art therapy for mourning on the grief, depression and ego-integrity of elderly people bereaved of their spouses. The subjects were 26 randomly selected senior citizens who used a senior welfare center in the city of Busan and who were bereaved of their spouses. They were divided into an experimental group of 13 and a control group of 13, and then an experiment was implemented. A group art therapy for mourning was provided for the experimental group in eight sessions, once a week, 180 minutes each, and no action was taken with the control group during the same period of time. The instruments used in this study were a grief scale, a depression scale, and an ego-integrity scale. The findings of the study were as follows: First, the group art therapy for mourning was found to have a significant effect reducing grief. Second, the group art therapy for mourning was found to have a significant effect decreasing depression. Third, the group art therapy for mourning was found to have a significant effect on improving ego-integrity. Accordingly, the group art therapy for mourning was effective at ensuring the successful aging of the elderly bereaved of their spouses by relieving their grief and depression and by facilitating their ego-integration.
