Tackling stigma associated with intellectual disability among the general public: a study of two indirect contact...

Although evidence abounds that people with intellectual disabilities are exposed to stigma and discrimination, few interventions have attempted to tackle stigma among the general public. This study set out to assess the impact of two brief indirect contact interventions on lay people's inclusion attitudes, social distance and positive behavioral intentions, and to explore emotional reactions towards the two interventions. 925 participants completed the first online survey. Participants were randomized to watch either a 10 min film based on intergroup contact theory, or a film based on a protest message. In total, 403 participants completed the follow-up survey at one month. Both interventions were effective at changing inclusion attitudes and social distance in the short term and these effects were partially maintained at one month. The protest based intervention had a greater effect compared to the contact one on aspects of inclusion attitudes and evoked stronger emotional reactions. Despite small effect sizes, brief indirect contact interventions may have a potential role in tackling public stigma associated with intellectual disability but their effects on behavioral intentions are questionable.
