This experimental study was designed to show the effects of parent training program on Iranian children with behavioral disorders. 27 students (7-11 years olf) with behavioral disorders were selected from Amerian elementary shools's girls. These students were assessed by Rutter's behavioral, asssessment test, completed by parents and teachers. Then their mothers were randomly assigned to one of three groups i.e. experimental group 0n=9), placebo (n=8), and control group (n=10). These groups were matched for age, education and socioeconomical status. The mothers in the parent-training group received 8 sessions of professional contact twice a week.

Treatment consisted of teaching parents to reward compliance and appropriate behavior and to use ignorance and time out for noncompliance and inappropriate behavioirs. The mothers in the placebo group participated in 5 sessions without training and therapeutic intervention. Control group participated only in pre-test and post-test.

Two months after starting the parent training sessions, subjects were re-evaluated.

Results indicated significant improvement in the target behaviors for experimental group. It may be concluded that mother training program was effective.
