BACKGROUND:

Today, most societies are exposed to the adverse effects of substance abuse. Drug dependence disrupts individuals’ decision-making styles and sexual functioning. Therefore, the present study was conducted to determine the effectiveness of matrix therapy on the decision-making styles and sexual satisfaction of marijuana addicts.

MATERIALS AND METHODS:

In this quasi-experimental study, conducted in early 2024 in Tehran, 30 male marijuana users were selected from addiction treatment centers using convenience sampling. Participants were randomly assigned to either an intervention group ( n = 15), which received 14 matrix therapy sessions, or a control group ( n = 15), which received no intervention. Both groups completed the General Decision-Making Styles Questionnaire and the Sexual Satisfaction Questionnaire at baseline, postintervention, and 1-month follow-up. Data were analyzed using repeated-measures ANOVA and Bonferroni post hoc tests (SPSS v23; significance level P < 0.05).

RESULTS:

No significant pretest differences were observed between groups. Matrix therapy significantly improved rational decision-making ( P < 0.001) and reduced intuitive ( P < 0.001), dependent ( P < 0.001), and spontaneous ( P < 0.001) styles. No significant change was observed in avoidant style ( P = 0.340). Additionally, the intervention group showed significant improvements in sexual desire ( P < 0.001), attitude ( P < 0.001), quality of life ( P < 0.001), and total sexual satisfaction ( P < 0.001), but not in compatibility ( P = 0.653).

CONCLUSION:

Matrix therapy is effective in enhancing cognitive control and sexual satisfaction among marijuana users, though certain domains may require supplementary interventions. The findings support its inclusion in comprehensive addiction treatment programs.
