Randomized Controlled Trial of a Brief Video Intervention to Reduce Self-Stigma of Mental Illness.

Objective: Self-stigma, a phenomenon wherein individuals internalize self-directed negative stereotypes about mental illness, is associated with negative outcomes related to recovery. This randomized controlled study assessed the efficacy of a brief social contact-based video intervention in reducing self-stigma in a large sample of individuals ages 18-35 endorsing an ongoing mental health condition. We hypothesized that the brief video would reduce self-stigma. Methods: In January and February 2023, we recruited and assigned 1,214 participants to a brief video-based intervention depicting a young individual living with mental illness sharing his personal story or to a non-intervention control. In the 2-minute video, informed by focus groups, a young individual described struggles with mental illness symptoms; this was balanced with descriptions of living a meaningful and productive life. Self-stigma assessments (Stereotype Endorsement, Alienation, Stigma Resistance, Perceived Devaluation Discrimination, Secrecy, and Recovery Assessment Scale) were conducted pre- and post-intervention and at 30-day follow-up. Results: A 2 ✕ 3 group-by-time analysis of variance showed that mean self-stigma scores decreased in the intervention arm relative to control across 5 of 6 self-stigma domains: Stereotype Endorsement (P = .006), Alienation (P < .001), Stigma Resistance (P = .004), Secrecy (P < .001), and Recovery Assessment Scale (P < .001). Cohen d effect sizes ranged from 0.22 to 0.46 for baseline to post-intervention changes. Baseline and 30-day follow-up assessments did not significantly differ. Conclusions: A 2-minute social contact-based video intervention effectively yielded an immediate but not a lasting decrease in self-stigma among young individuals with ongoing mental health conditions. This is the first study to examine the effect of a video intervention on self-stigma. Future trials of self-stigma treatment interventions should explore whether combining existing interventions with brief videos enhances intervention effects. Trial Registration: NCT05878470.
