The effectiveness of treatment based on outpatient deep matrix model and stages of change on improvement of self-regulation and self-efficacy of drug abstinence

Various psychological treatments have been provided for addiction treatment. The aim of the current study was to compare the effectiveness of treatment based on matrix deep outpatient model and stages of change on improvement of self-regulation and self-efficacy of drug abstinence in men addicted to amphetamines. For this purpose، 45 male drug abusers of amphetamines who referred to Razi addiction medicine clinic were selected، randomly، in a semi- experimental study with pre-test، post-test and in a 3 month follow up with a control group. They were assigned to two groups of experiment and control (a group intervention model based on outpatient deep matrix and other intervention stage of change model). The groups were evaluated both before and after the treatment and 3 months after the completion of treatment on emotional self-regulation، self-efficacy، and drug abstinence. The two groups of experiment underwent 16 sessions of treatment based on outpatient deep matrix model and stages of change، twice weekly. The result of multiple covariance analysis indicated the effectiveness of both models of treatment on reduction of emotional self-regulation problems and an increase in self-efficacy of drug abstinence. Comparative results indicated more effectiveness and stability in stages of change model compared to deep outpatient model in the post-test and three months follow-up on emotional self-regulation and self-efficacy of drug abstinence. It seems emotional self-regulation is important for the treatment of addiction and they consider emotional self-regulation as an effective mechanism on a change in clinical interventions.
