Effectiveness of Work with Clay in Reducing Primary School Children's Aggression

This study seeks to determine the effect of clay therapy on the aggression of 7-12 years-old school children. For this purpose, 35 aggressive elementary school children of Tehran were selected according to the aggression scale of CBCL test. Then, they were randomly divided into control (n=14) and experimental groups (n=21). The experimental group went under clay therapy while control group received no treatment. The two groups were evaluated immediately after the treatment session and two months later. Data were analyzed based on the repeated analysis of variance (between-within the mixed group). The F parameter showed that clay therapy is able to reduce the aggression of the experimental group in comparison to the control group. These results were also observed during follow-up period.
