This study developed a group horticultural therapy(HT) for battered women in Korea and tested its effectiveness. The activities in the HT were formatted to increase the self-esteem and decrease the depression. The major finding was that the self-esteem scores significantly increased and the depression scores of the 12 battered women in the experimental group significantly decreased after the intervention. The change in levels of self-esteem and depression in the experimental group were significantly different from those of the 12 the subjects in the control group. Therefore, both family violence victims and assaulters are demanded to introduce the horticultural therapy activities actively.
