In the two experimental and control groups (27 people each) it was replaced by simple random and using lottery, before the implementation of the intervention program to both groups of subjects, the Individual Adaptation Questionnaire of Children (1998) March et al.'s multidimensional anxiety scale (1997) and Hepner and Peterson's (1982) problem solving questionnaire were given to them and they were asked to answer all the questions carefully with the help of their parents. and after collecting the data, the play therapy program was implemented on two experimental groups and then they were asked to answer all the questions of the above questionnaires for the post-test. 4 questionnaires were discarded due to incompleteness and finally the analysis was done on a sample of 50 people who had completed the questionnaire; Multivariate analysis of covariance test was used to analyze the data.
