Misconceptions toward methadone maintenance treatment (MMT) and associated factors among new MMT users in Guangzhou, China

The methadone maintenance treatment (MMT) program is scaling up in China, but little is known about drug users' cognitions of MMT. To investigate the prevalence and associated factors of MMT-related misconceptions, a totally of 300 newly admitted MMT users were interviewed in three MMT clinics in Guangzhou. Four statements were used to assess MMT-related misconceptions. The results showed that the majority of participants misconceived that MMT is intended primarily for detoxification (92.3%), that one could be completely detoxified and quit using methadone after using it for 2-3 months (64.2%), that MMT is not a long-term or even lifetime treatment (77.9%); and that one should attempt to reduce its treatment dosage as methadone is harmful to one's health (84.3%); 48.5% of the respondents possessed all four types of misconceptions. Prior experience of methadone use in voluntary drug detoxification centers (OR = 1.82 to 2.55, p<0.05) was associated with some misconception items, whilst being introduced by some peer drug users or community members to use MMT (versus not being introduced by anyone; OR = 038 to 0.50, p<0.05), having taken up HIV voluntary counseling and testing prior to admission (OR = 0.52, p<0.05), and a higher HIV-related knowledge level (OR = 0.38, p<0.05) were associated with lower likelihoods for possessing some of the misconceptions. The findings suggested that MMT-related misconceptions were very prevalent among newly recruited MMT users in China. Misconceptions are potential factors causing drop-outs. Interventions targeting such misconceptions are greatly warranted. (c) 2012 Elsevier Ltd. All rights reserved.
