Effects of Acceptance and Commitment Therapy on the Psychological Capital and Temptation of Methadone-Maintenance Treated Patients

Background: Addiction is a condition in which a person makes bad habits, such as the use of drugs, nicotine, and alcohol. Objectives: The present research aimed to assess the effectiveness of the Acceptance and Commitment Therapy (ACT) in the psychological capital and temptation of methadone- maintenance treated patients. Methods: This quasi-experimental study was conducted based on a pretest-posttest control group design. The statistical population consisted of all methadone-maintenance treated patients in substance addiction treatment clinics in Mashhad. From this population, 30 people were randomly selected by simple random sampling (with replacement) and assigned to two groups of experimental (n=15) and control group (n=15). The data collection tool was Luthans's Psychological Capital Questionnaire and Wright's Craving Beliefs Questionnaire. The data were analyzed in SPSS software (version 21) using univariate and multivariate covariance. Results: Based on the research findings, the ACT approach had a positive and significant effect on psychological capitals and its components (self-efficacy, hope, resiliency, and optimism) (P<0.001). Furthermore, it exerted a significant effect on the reduction of temptation and relapse in methadone-maintenance treated patients (P<0.001). Conclusion: As evidenced by the obtained results, it can be concluded that the ACT can increase psychological capital and reduce the temptation of methadone-maintenance treated patients
