Addressing rural and non-rural substance use disorder stigma: Evidence from a national randomized controlled trial.

Background: Individuals with substance use disorder (SUD) and recovery support services often face significant social stigma, especially in rural areas. One method of addressing stigma is through education and personal recovery stories. It is unclear if such messages will work similarly across rural and non-rural areas. Methods: We conduct an exploratory analysis of data from a national randomized controlled trial (N = 2,721) to determine if there are differences in the effectiveness of messages at reducing stigma across rurality. Specifically, we test four interventions to reduce stigma: education about the effectiveness of recovery housing and three versions of a personal recovery story that varied social distance and delivery medium (identified written story, anonymous written story, and video). Results: We find that messages may not have the same effect across rurality, with non-rural participants in the identified and anonymous written recovery story groups having lower stigma scores and only rural participants exposed to the anonymous written story having lower stigma scores compared to their counterparts in the control group. Further, non-rural participants exposed to both written story treatments had higher positive feelings towards those in recovery compared to the control group, but only rural participants in the anonymous written story group had higher positive feelings compared to the control group. Conclusion: Our results suggest that messages may have different effects on stigma across rurality and that rural participants' beliefs may be particularly hard to change. Future research should examine what types of stigma reduction interventions are most effective in rural areas.
