Effectiveness of Matrix Model in Relapse Prevention and Social Support Enhancement among Subjects with Opiate Substance Dependency

The aim of this study was to determine the effectiveness of Matrix model in enhancement of social support and relapse prevention in subjects with opiate dependency.
In a semi-experimental study, 34 subjects with diagnosis of opiate dependency who successfully detoxified were divided into two experimental group (16 subjects) and control group (18 subjects) selected by cluster random sampling method. The experimental group received 32 sessions of Matrix model training and the control group did not receive any treatment. All subjects were assessed by Social Support Appraisal Scale (SSAS) and morphine test before treatment, randomly during treatment, after treatment, and after a 4month follow up stage. Data analyzed by using 2 test, Multivariate Analysis of Covariance (MANCOVA) and Analysis of Covariance (ANCOVA).
2 test result showed that experimental and control groups had a significant difference in relapse rates. In addition, Analysis of Covariance (ANCOVA) showed a significant difference between two groups in social support enhancement at periods of post-test and follow up.
Study results indicated that Matrix model is effective in relapse prevention and social support enhancement in people with opiate substance dependency.
