The purpose of this study is to investigate if and how an art therapy program for the dyad of mother and daughter can be helpful to change the mother\'s attitude of raising the child, so as to reduce the daughter\'s anxiety caused by the mother. Study subjects are Setbyulyee (a fictitious name), an elementary school child in the fifth grade, and her mother, both of whom received total 23 sessions of art therapy from April 13 to July 21, 2006, with one session-two session a week and each meeting lasting 4 hours. Research tools used for the child are PSCD, and pre-, post- and following-tests for Anxiety scale in order to analyze the child\'s perceptions as to her school life and family as well as changes of the child\'s anxiety level; on the other hand, the mother was given a scale of parenting attitude together with pre-, post- and following-tests for KFD to check the mother\'s attitude and psychological condition regarding the child\'s education. The results obtained from the study and discussion of it are as follows. First, art therapy for mother-daughter dyad proves to be effective for parenting attitude changes, in the sense that the therapy has improved the mother\'s level of kind-feeling and acceptance on her parenting attitude while it has reduced her attitude or behavior of disapproval and punishment. This indicates that the mother realized during the art therapy her parenting attitude ineffective, and changed her attitude to become more lenient and acceptive. Second, the mother-daughter dyadic art therapy helps to reduce the child\'s anxiety to the extent that during the therapy the child could hold of her anxiety and become relaxed and stable to express her repressed feelings, which itself reduces the level of the child anxiety. Third, art therapy of mother-daughter dyad gives the dyad a change in their relationship in a way that the mother found her parenting attitude not working, then changed and improved on it; and in the meantime, the daughter reciprocated the mother\'s change with her own positive behavioral changes to end up with recovery of their good mother-daughter relationship. Accordingly, this study would claim that an art therapy program for mother-daughter dyad can be very effective to improve the mother\'s parenting attitude and as a consequence to alleviate the child\'s anxiety, and might be useful for psychotherapy on children with anxiety.
