The Efficacy of Matrix Model Treatment in the Reduction of Addiction Severity and Relapse Prevention among Amphetamine Abusers

Background and Objective: Amphetamine abuse has become a major problem in recent years. The aim of this study was to examine the efficacy of Matrix Model treatment in  amphetamine abusers. Materials and Methods: This study was a clinical trial with a pretest-posttest design. The study population included all known abusers of amphetamines in Zanjan, Iran.The sample consisted of ۴۰ people referring to local psychiatric and psychological clinics. They were chosen based on convenient sampling and were randomly assigned into two groups, pharmacotherapy and combined therapy (pharmacotherapy and Matrix Model treatment). ASI questionnaires and urinary tests were administered before and after treatment and the data were analyzed using ANCOVA and chi-squared tests. Results: The treatment was effective when considering job status, drug and alcohol abuse, salary, family and mental status (p= ۰/۰۰۱). In terms of the medical status of addiction severity, there was no significant difference between the two groups. Chi test showed that the frequency of positive urinary tests decreased in the combined therapy group (p= ۰/۰۵). Conclusion: Results suggest that the Matrix Model Treatment can reduce addiction severity and can also reduce the frequency of positive urinary tests.
