Abstract
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 any significant change in extrinsic motivation,
interpersonal help seeking and perception of self-efficacy. In the followup process, a significant decrease was observed in the participants’ selfefficacy perceptions.
Conclusions: Group work with substance users increases the intrinsic
motivation and confidence-in-treatment of individuals. Therefore, group
work practices will increase the effectiveness substance use treatment.
