          Abstract

          Experience of stigma towards methadone maintenance treatment (MMT) may be a barrier to use of this treatment by people with opioid use disorder. We evaluated the factor structure, internal reliability, construct, and criterion validity of a theory-based stigma measure, the Methadone Maintenance Treatment Stigma Mechanisms Scale (MMT-SMS) and compared this with the Substance Use Stigma Mechanism Scale SU-SMS. Surveys at the beginning and end of a prospective study together with records of drug use and treatment attendance during that study. Community methadone clinic in the Northeastern US. Ninety-three participants who were receiving MMT; average daily methadone dose was 84.8mg/day (SD=28.4mg/day). The MMT-SMS uses a self-report questionnaire to assess three dimensions reflecting experiences of anticipated (9 items), enacted (9 items), and internalized stigma (7 items) specifically related to receiving MMT. Anticipated and enacted scales include three stigma source subscales (family, employers, healthcare workers; 3 items each). Responses are recorded on a 5-point Likert-type scale, then averaged to produce the MMT-SMS scale/subscale scores. The SU-SMS is a self-report questionnaire to assess experiences of anticipated, enacted, and internalized stigma regarding substance use history. Both scales were administered at the final parent study visit. Other measures included were assessed in the parent study and used to assess lifetime and recent MMT (e.g. current MMT dose) and drug use experiences (e.g. past 30-day heroin injection). The MMT-SMS demonstrated good internal reliability (α=0.806–0.952 for components). Confirmatory factor analysis supported the 7-factor scale structure, distinguishing between experiences of anticipated, enacted, and internalized stigma, and anticipated and enacted stigma source subscales (family, employers, healthcare workers) (RMSEA=0.076, 90%CI=0.061–0.090, p-close=0.003; CFI=0.974; TLI=0.971). Construct validity helped distinguish the MMT-SMS from established substance use stigma constructs. Criterion validity observed associations with substance use experiences while on MMT, likely to predict future MMT success. Internalized MMT stigma was uniquely associated with daily MMT dose. Regarding criterion validity: anticipated MMT and enacted substance use stigma were associated with past 30-day heroin injection, MMT stigma uniquely associated with opioid use behaviors while receiving MMT, and substance use stigma broadly associated with injection-related behaviors. The Methadone Maintenance Treatment Stigma Mechanisms Scale appears to be a reliable measure of methadone maintenance treatment stigma with robust validity in a sample of persons with opioid use disorders receiving methadone maintenance treatment.
