This study is a case study of sandplay therapy for a twelve-year-old girl -“Jo”-who witnessed domestic violence by her father towards her mother from infancy into her childhood. This study employed Kalff`s sandplay techniques based on Jungian psychoanalytic theory as its therapeutical approach to Jo. Jo received counselling for twenty-three sessions over a period of six months during which time she made twenty sand boxes. Jo`s stories about her sand boxes and the meanings of her symbols were interpreted in terms of Kalff`s phases of ego and psychic development. Through the process of sandplay therapy, many characteristics of Jo`s inner world were reborn and nurtured. Thus empowered, she was able to seize the center of her Self. Her old Self had been characterized by stubbornness, abusiveness, selfishness and even violence. But through the process of making her ego emerge and develop from her Self, Jo`s maladaptive behaviors gradually decreased and she became able to healthily adapt to her circumstances with her family, in the women`s refuge shelter, and at her school. The results of this study suggest that sandplay therapy may be an efficient therapeutic technique for children who have witnessed family violence.
