The MMT-SMSmeasures enacted stigma (experiences of discrimination from others in the past or present), anticipated stigma (expectations of experiencing discrimination from others in the future), and internalized stigma (endorsement and application of negative beliefs and feelings about people receiving methadone and applying them to the self) among people receiving methadone maintenance treatment (MMT). Enacted and anticipated stigma from family members, employers, and healthcare workers are measured. The scale may be adapted for persons experienced with other forms of medication-assisted therapy for opioid use disorders.

I worked with Dr. Laramie Smith and our colleagues to develop, pilot, and psychometrically evaluate this scale among people receiving MMT.
