Problems in today’s families are multiple, including non-functioning conjugal relations and violence, and such problems can lead to the disintegration of the family. Mandala Art Therapy, informed by C. G. Jung’s method of finding the self through exploring the conscious and unconscious, can be employed to help solve these problems. Mandala Art Therapy helps effect a serene mind and ability to concentrate. A positive self-image is developed, a sense of achievement is created, and thus self worth is increased and experienced. In this study, the K-HTP Picture Test was given before and after therapy to measure changes in self esteem. Results showed Mandala Art Therapy to be effective in fostering mental and physical harmony in married couples, resulting in healthy families. The results raise the hope that this therapeutic approach will become an important tool for social workers in their daily counseling.
