The purpose of this research was to study the effectiveness of play therapy on decreasing behavioral disorders of physically- emotionally abused students of 9 -12 years old in Tehran city. From the population, of all the physically- emotionally abused students inhabiting supportive institutes of Tehran, an available sample of 24 people were selected and assigned into two groups of experiment (n=12) and control (n=12). The experiment group had10, 45 minute sessions of play therapy twice a week with 5 individual sessions and 5 group sessions. After finishing play therapy program, both groups were given post-test. Data collecting instrument used here was Achenbach Children Behavioral Check List (CBCL). Since we lack the assumption of having a normal distribution, we analyzed data using non-parametric test of Umann-whitney. Findings demonstrated that play therapy decreases the degree of anxiety/depression in physically emotionally abused students but it doesn’t decrease the degree of behavioral disorders, aggression, withdrawn, depression, and attention problem in physically-emotionally abused students. Although play therapy was effective within groups and has decreased the degree of these disorders, it was not however significantly effective enough to statistically differentiate the groups.
