Introduction: Group work is one of the most effective treatment methods in rehabilitation of substance use behavior. In addition, the individual's motivation to quit substance and self-efficacy perceptions of quitting are important factors for the course of the treatment. Therefore, the aim of this study was to investigate the effect of group work process on motivational processes (intrinsic and extrinsic motivation, interpersonal help seeking and confidence-in-treatment subscales) and self-efficacy perception of substance users. Method: This is an experimental study with 43 substance users. The Treatment Motivation Questionnaire subscales were used to measure the effect of the group work on the dimensions of treatment motivation (intrinsic motivation, extrinsic motivation, confidence-in-treatment, interpersonal help seeking), and the General Self-Efficacy Scale was used to measure the effect of group work on the self-efficacy perceptions. Results: The group work resulted in a significant increase in participants' intrinsic motivation and confidence-in-treatment. However, group work did not result in any significant change in extrinsic motivation, interpersonal help seeking and the perception of self-efficacy. In the follow-up process, a significant decrease was observed in the participants' self-efficacy perceptions. Conclusions: Group work with substance users increases the intrinsic motivation and confidence-in-treatment. Therefore, group work practices will increase the effectiveness of substance use treatment.
