Are the self-stigma and perceived stigma of patients treated with methadone or buprenorphine still a problem fifty years after the marketing authorization for opioid agonist treatment? The observational STIGMA study.

BACKGROUND

In the context of the opioid overdose crisis, understanding the barriers to seeking, attaining and remaining in treatment for patients with opioid use disorder (OUD) is a public health issue. To date, very few studies have assessed the "self-stigma" (i.e., the internalization of negative societal attitudes and stereotypes about oneself, leading to self-judgment) and "perceived stigma" (i.e., the belief that others hold negative attitudes towards oneself due to a particular condition) experienced by patients with OUD receiving opioid agonist treatment (OAT), and none have done so in France. Our study aimed to quantify self-stigma, explore some aspects of perceived stigma, determine the factors associated with greater self-stigma and examine whether the level of self-stigma was related to a delay in seeking care.

METHODS

The STIGMA study was a monocentric, cross-sectional study. The data were collected in a French hospital addiction medicine department. Participants were outpatients with current or past OUD who were still receiving or had received OAT. A questionnaire assessing sociodemographics; OUD characteristics; perceived stigma; and quantification of self-stigma by the Self-Stigma Scale-Short, was administered.

RESULTS

A total of 73 questionnaires were included in the analysis. Nearly two-thirds of the patients had a "moderate to high" level of self-stigma. These patients were significantly younger at OUD onset and were significantly more likely to have at least one dependent child than patients reporting a "very low to low" level of self-stigma. Nearly half of the participants experienced perceived stigma from a healthcare professional regarding their OUD or OAT, and nearly one-third of the participants were refused care from a healthcare professional because of their OUD or OAT. Moreover, a quarter of the sample reported delaying care due to fear of being stigmatized. We did not find a relationship between self-stigma levels and a delay in seeking care.

CONCLUSIONS

Our study highlights the need to detect stigma and to improve training in addiction medicine.
