Opening Minds coordinated and funded a series of evaluation projects of anti-stigma programs for healthcare providers, one of OM's key target groups, with the purpose of determining program outcomes. While OM's partner programs in general have shown overall evidence of positive change, there has been considerable variation among the programs in terms of their effectiveness. As well, among the programs that have had the strongest results, they were not uniform with respect to their target audience, program content, program length, type of social contact provided or program setting. As such, a qualitative investigation was undertaken to examine programs in greater depth and detail. The purpose of the qualitative research was to identify best practices and strategies among OM's partner programs, to identify key program ingredients for effective stigma reduction, to better understand why some programs were more successful than others and to gain further theoretical insight to the process of building successful anti-stigma programs for healthcare providers.
