Abstract

Introduction: This study was aimed to examine effectiveness of Stress Inoculation Training on physical aggression, verbal aggression, anger and hostility in adolescent boys.
Method: This study is quasi-experimental and pretest - posttest with control group. The study population included adolescent boys aged 12-15 years old in Mashhad. The sample was 24 students that were selected according to gain the highest score in Buss Perry Aggression Questionnaire and randomly was assigned to experimental and control groups. Buss Perry Aggression Questionnaire was used as tool in current study. The experimental group received 8 sessions of Stress Inoculation Training but the control group did not receive any psychological treatment. Multivariate Analyses of covariance and One-Way Analysis of covariance were used to analyze the data.
Results: Findings indicated that Stress Inoculation Training significantly reduced hostility, physical aggression and verbal aggression in experimental group in comparison to control group (p < 0.01). However, no significant change was observed in anger in experimental group in comparison to the control group.
Conclusion: Stress Inoculation Training is effective method by affecting on cognitive and behavioral dimension for reducing aggression and hostility. However, more comprehensive intervention (including family and society) with more therapeutic sessions would probably be effective in reducing anger (emotional dimension of aggression)
