The present study aimed to compare the effectiveness of Metacognitive Therapy (MCT) and Time Perspective Therapy (TPT) self-Efficacy of quitting in individuals with substance dependence. This quasi-experimental research employed a pre-test, post-test, and two-month follow-up design. The statistical population included all individuals with substance dependence who referred to addiction treatment centers in Kermanshah in 2024. Based on inclusion and exclusion criteria, 60 eligible participants were selected through convenience sampling and randomly assigned to three groups (two experimental and one control), each consisting of 20 individuals. The Self-Efficacy of Quitting Scale (Bramson, 1999) was administered during the pre-test, post-test, and follow-up phases. Data were analyzed using repeated measures and Bonferroni post-hoc tests at a significance level of 0.05 via SPSS-26. The findings revealed a significant difference between the control group and both treatment groups regarding self-Efficacy of quitting. Both metacognitive therapy and time perspective therapy significantly increased self-Efficacy of quitting, and these effects remained stable during the follow-up phase. Furthermore, metacognitive therapy proved to be more effective than time perspective therapy in enhancing self-Efficacy of quitting. Based on these results, although both treatments can be used to improve self-Efficacy of quitting in individuals with substance dependence, metacognitive therapy may offer greater practical implications for psychologists and psychiatrists due to its superior effectiveness.
