The effectiveness of group sandtray therapy was examined using a pretest-posttest control group design with young adolescent girls (n = 37) identified as having low self-esteem. A split-plot analysis of variance (SPANOVA) revealed statistically significant differences between participants in the treatment and control groups in self-esteem on five of the six subscales of the Self-Perception Profile for Children. The implications of the findings are discussed. (Contains 1 table and 2 figures.)
