Methods: In a field trial, we evaluated the efficacy of group behavioral therapy, art and sport supportive interventions in Bam earthquake children survivors with PTSD symptoms and compared it with a control group. Before and after interventions we evaluated the PTSD symptoms using K-SADS-PL semi-structural interview for each group and compared them using appropriate statistical methods. Results: The participants were 200 individuals who were randomized in four groups according to an intervention program including: Group behavioral therapy; Group behavioral therapy plus art and sport interventions; Art and sport interventions; and control group. During the interventions, 39 individuals were excluded. None of the participants had severed PTSD or other psychiatry disorders that needed pharmacological interventions. In interventional groups, the reduction of total PTSD symptoms and the symptoms of re-experience, avoidance and hyper arousal was not statistically significant. However, in the control group, the PTSD symptoms increased during the study which was statistically significant. Conclusion: Group behavior therapy and supportive interventions (art and sport) may have preventive effects on PTSD symptoms. https://ijps.tums.ac.ir/index.php/ijps/article/view/498 https://ijps.tums.ac.ir/index.php/ijps/article/download/498/460
