The purpose of the present study was to determine the effectiveness of parent-based intervention during incredible years on behavioral problems of 5-7 years old intellectual disable children. The research method was experimental with pretest-posttest design and follow-up with control group. The statistical population consisted of educated intellectual disability students (n=128) who were educated in special centers of Lordegan City in 2018. Thirty individuals with behavioral problems were selected randomly based on Rutter's Behavioral Problems Scale (1975, Parent Form) and randomly assigned to two groups of 15 (experiment and control) and then the experiment group's parents in 12 sessions received Incredible Years Intervention, while the parents of the control group did not receive any intervention during this time. At the end of the intervention period and 3 months later, Rutter's Behavioral Problems Test (Parent Form) was again answered by the two groups as post-test and follow-up, respectively. The obtained data were analyzed by repeated measures ANOVA using SPSS22 software. The results showed that there was a significant difference between the performance of the experiment and control groups in the behavioral problems in the subscales (aggression and hyperactivity, social maladaptation, antisocial behavior and attention deficit disorder) (p<0.005). According to the results, the intervention program of Incredible Years can be used as an effective intervention method to reduce the behavioral problems of intellectual disability children.
