Background: Anger and aggression have been developing notably in societies, especially among patients depending on substance abuse. Therefore, this study aimed to investigate the effect of anger management based on group education among patients depending on substances according to Patrick Reilly's cognitive behavioral approach.
Methods: In a quasi- experimental study, all patients who met the inclusion criteria were evaluated regarding their aggression level. The participants were assigned to 12 educational sessions based on group therapy and Patrick-Reilly's anger management by focusing on using a combination of cognitive intervention, relaxation, and communication skills. The data were analyzed using the SPSS statistical software, version 16.
Results: The findings showed a significant difference between the two groups regarding aggression level after the intervention (p = 0.001). No significant relationship was observed between aggression level and demographic variables (p > 0.05).
Conclusion: The intervention of this study can be used for establishing self-management and decreasing anger among patients depending on substances. They can also be used as a therapeutic program in addition to pharmacotherapy.
