trauma by applying art therapy to women who are early adults with attachment trauma. The subjects of this study were women who were early adults in their first year of university, complaining of poor academic performance, self-criticism, and depression. From November 2021 to February 2023, art therapy was conducted once a week for 50 minutes in a total of 35 sessions. To examine the changes in attachment trauma, changes in attachment trauma were compared using session diaries, livestock records, picture data, and MMPI-2, BDI, and KFD tests. As a result of the study, the subjects of the study were able to reduce criticism of themselves, manage and control emotions, and reconstruct the damaged self-system to care through self-reflection. This change could be confirmed by the fact that the depression score in MMPI-2 decreased from 76 points to 58 points and the BDI scores decreased. In addition, changes in the location and characteristics of the KFD person, and in distance and content, also changed the family relationship, which is the basis of attachment. These results show that art therapy has a positive effect on changes in values, self-awareness, expansion to life, and attitudes by strengthening internal competence in the areas of cognition, emotion, and reality of early adult women with attachment trauma. Based on these findings, the significance and limitations of this study were discussed.
