The effectiveness of a transtheoretical model based on health education intervention on adherence to methadone maintenance treatment: a quasi-experimental study

The study's findings indicate that the educational program successfully improved participants' knowledge and skills regarding the processes of change, as well as their self-efficacy, which was assessed through two key constructs: temptation and confidence. However, the program did not succeed in enhancing participants' adherence to treatment. Policymakers should consider integrating structured educational programs based on the Theory of Planned Behavior (TPB) into existing Medication Management Therapy (MMT) services. This approach aims to enhance patients' understanding of their treatment processes and promote adherence. Furthermore, since the intervention positively impacted self-confidence and self-efficacy, it is advisable to develop policies that focus on educating patients to bolster their self-efficacy in resisting drug-related temptations. Future studies should also aim to include diverse populations, such as women and individuals from various age groups, to assess the generalizability of the findings beyond the male participants from specific regions.
