Modeling Structural Equation of Behavioral Brain Systems on Self-efficacy,Coping Strategies, the Mediating Role of Emotion Regulation in MethadoneAddiction Withdrawal

The aim of this study was to investigate the mediating role of emotion regulation in the relationship between behavioral brain systems with coping strategies and self-efficacy in methadone addicts. The method used in this study is descriptive correlation; the statistical population in this study includes all methadone addicts referred to Modares Psychiatric Center in February and March 2017 and April 2016, from which 195 people were randomly selected as a sample. Data collection tools were Wilson, Gary and Bart (1989) Personality Questionnaire, Styles Against Stress Billings and Moss (1981), Schwartz and Jerusalem (1979) General Self-Efficacy Questionnaire, and Gratz & Roemer (2004) Emotion Regulation. The results of structural equations showed that behavioral brain systems are effective on coping strategies, emotion regulation and self-efficacy and emotion regulation is effective on coping strategies and self-efficacy (P 05 0.05). The results also showed that the model has a good fit and explains 62% of the effect of total behavioral brain systems on coping strategies through emotion regulation mediator and 29% of the effect of total behavioral brain systems on self-efficacy through emotion regulation mediator.
