Aim: The purpose of this study was to determine the effectiveness of mode deactivation group therapy (MDT) on reducing aggression of boy adolescents covered by Welfare Organization. Method: The research method was quasi-experimental, pretest-posttest and three-month follow-up with experimental and control groups. The statistical population of the study was 38 adolescent boys, age range 12-18 years, who covered by cultural-educational complex of Ashiyane-Rahmate-Elahi in region 11 of Isfahan, Iran, in 2019. Using purposeful sampling, 24 adolescents who have high score on the aggression questionnaire were selected and randomly assigned into experimental and control groups (12 participants in each group). Research tools included aggression questionnaire (Buss and Perry, 1992) which were completed in three phase by two groups. Apache & Di Meo (2012) Mode Deactivation Therapy program was run for the experimental group in nine weekly 75-minute sessions. Data were analyzed using mixed model repeated measures analysis of variance. Results: Results indicated that the MDT had a significant effect on decreasing reduced general aggression score (F = 23.23, P = 0.0001) and its subscales include physical aggression (F = 5.98, P = 0.005), verbal aggression (F = 3.75, P = 0.043), Anger (F = 8.45, P = 0.002), and hostility (F = 9.97, P = 0.0001) and this effect remained stable at follow- up. Conclusion: Since mode deactivation group therapy teach skills such as mindfulness breathing, emotional defusion, cognitive defusion, acceptance, and balancing beliefs toward alternative beliefs, it can be effective in reducing aggression and its dimensions.
