A web-based pilot randomized controlled trial to test the efficacy of education and contact-based interventions in reducing public suicide stigma.
Trial report in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04756219 (Beneficial and Harmful Effects of Reducing Public Suicide Stigma), which is not on this map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundInterventions to reduce public suicide stigma (i.e. negative attitudes towards persons affected by suicide/suicidality) could contribute to suicide prevention. However, such interventions could unintentionally increase suicide normalization (i.e. liberal attitudes towards suicide) and therefore increase suicide risk. We aimed to test the efficacy of education- and contact-based interventions delivered online via video or text on both public suicide stigma and suicide normalization.
methodsWe conducted a web-based randomized controlled trial among N = 2,043 participants recruited from an established online research panel. Participants were randomized into six groups, receiving either one of four contact- or education-based interventions that were transferred via text or video (contact text, contact video, education text, education video) or control group content (contact control, education control). Information about suicide stigma and suicide normalization were collected directly before (t
resultsMedian times spent with provided material were generally longer among participants exposed to video material than among participants exposed to text material, and among participants in contact-based interventions than among participants in education-based interventions. We did not observe stronger effects in intervention groups compared to control groups on suicide stigma or suicide normalization. Surprisingly, suicide stigma and suicide normalization appeared to decrease from t
conclusionOur findings suggest a higher attractiveness of video- and contact-based material compared to text- and education-based material. However, none of the interventions had a significant effect on public suicide stigma or suicide normalization. Future research should explore innovative and safe approaches to reduce public suicide stigma. Experimental studies may focus on interventions with higher attractiveness (i.e. video and contact-based interventions), use interventions with higher intensity (i.e. longer interventions, more repetitions), and assess suicide stigma with implicit measures to avoid response bias.
