The purpose of this research is to examine the effectiveness of group sandtray therapy at school with preadolescents identified with behavioral difficulties. This is a pretest-posttest control group design.

The effect sizes were medium (d= .52-.59). According to parents' reports, a statistically significant difference was found regarding preadolescents' externalizing behavior problems, and the effect size was medium (d=.63). No statistically significant differences were found regarding preadolescents' total behaviors and internalizing behavior problems based on BASC-PRF. The ...
