Method: This study was conducted via a quasi-experimental research design along with pretest/posttest/ control group. The research sample consisted of 24 methamphetamine-dependent participants (12 ones in the experimental group and 12 ones in the control group) through simple random sampling and were randomly assigned to two experimental and control groups. Schneider's Self-Control Questionnaire (1974) was used. Results: One-way covariance analysis showed that matrix therapy improves self-control (P <0.05). Conclusion: It can be argued that matrix therapy is beneficial in increasing self-control and reducing return to substance use. M3 ER -
