The effectiveness of matrix interventions in improving methadone treatment.

BACKGROUND

The treatment of opioid dependence disorder is one of the major problems in medical centers around the world. Although MMT has been the major treatment in last few years in Iran, the existence of relapse before and after detoxification is still high. Methadone treatment has had a very low percentage of complete success.

OBJECTIVES

To evaluate the effectiveness of matrix group interventions in improving methadone treatment in the addicted was the main goal of this research.

MATERIALS AND METHODS

In a semi - experimental design, 24 male patients on the qualification cutoff score for the questionnaire survey (score less than 19 in depression test, and less than 21 in anxiety test) and the diagnosis of opioid dependence according to (DSM - IV) were substituted in two experimental and control groups randomly. At the beginning of the study, after the treatment period and in the follow-up phase (three months after the end of treatment), participants were evaluated by Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and the Anger Questionnaire (AQ), control group with no psychological treatment only took methadone. Data were analyzed using covariance analysis, chi square and Repeated Measures Analysis of Variance.

RESULTS

Results showed that the effect of matrix group interventions on reducing relapse (P < 0.05), increasing the maintenance of treatment (P < 0.01), increasing the treatment compliance, reducing anger, anxiety and depression and methadone dose is more effective than methadone treatment (P < 0.05).

CONCLUSIONS

It seems matrix group interventions increase the effectiveness of methadone treatment by reducing the relapse prevention, the dose of methadone and remaining in treatment.
