Methadone Maintenance Therapy (MMT) is one of the treatment processes under the concept of harm reduction from drug addiction. It is effective for treatment retention resulting in good outcome, reducing relapse, risk behaviors to themselves as well as others and improving quality of life. This retrospective study was aimed to determine the predicting factors of one year retention in MMT at Princess Mother Institute on Drug Abuse Treatment. Patient data was collected from outpatient medication profiles and the treatment reports of drug addiction using validated case record forms. The result was presented by percentage, mean and standard deviation and analyzed by Chi square test and logistic regression analysis to determine the association and predicting factors of one year retention in MMT. Of 173 patients, most of them were male (96.55%) with the mean age of 35.49 ± 11.39 years. The average methadone dose was 25.62 ± 11.67 mg/day. The predicting factors of one year retention in MMT were having career (OR = 4.29, 95% CI: 1.13-16.37) and earning more than 10,000 baht/month (OR = 3.74, 95% CI: 1.08-12.95). Therefore, the vocation training and employment support could enhance the retention in MMT leading to treatment success.
