Challenging the public stigma of mental illness: a meta-analysis of outcome studies.

OBJECTIVE: Public stigma and discrimination have pernicious effects on the lives of people with serious mental illnesses. Given a plethora of research on changing the stigma of mental illness, this article reports on a meta-analysis that examined the effects of antistigma approaches that included protest or social activism, education of the public, and contact with persons with mental illness. METHODS: The investigators heeded published guidelines for systematic literature reviews in health care. This comprehensive and systematic review included articles in languages other than English, dissertations, and population studies. The search included all articles from the inception of the databases until October 2010. Search terms fell into three categories: stigma, mental illness (such as schizophrenia and depression), and change program (including contact and education). The search yielded 72 articles and reports meeting the inclusion criteria of relevance to changing public stigma and sufficient data and statistics to complete analyses. Studies represented 38,364 research participants from 14 countries. Effect sizes were computed for all studies and for each treatment condition within studies. Comparisons between effect sizes were conducted with a weighted one-way analysis of variance. RESULTS: Overall, both education and contact had positive effects on reducing stigma for adults and adolescents with a mental illness. However, contact was better than education at reducing stigma for adults. For adolescents, the opposite pattern was found: education was more effective. Overall, face-to-face contact was more effective than contact by video. CONCLUSIONS: Future research is needed to identify moderators of the effects of both education and contact.

Changing stigmatizing perceptions and recollections about mental illness: the effects of NAMI's in Our Own Voice.

In Our Own Voice (IOOV) is a 90-min anti-stigma program that comprises face-to-face stories of challenges of mental illness and hopes and dreams commensurate with recovery. We pared down IOOV to a 30-min version, using information from two focus groups. In this study, effects of 90- versus 30-min IOOV are contrasted with 30 min of education. Two hundred research participants were randomly assigned to one of these three conditions and completed a measure of stigmatizing perceptions and recollections. People in the education group remembered more negatives than the two IOOV groups. To control for overall response rate, a difference ratio was determined (difference in positive and negative recollection divided by overall recollections). Results showed the two IOOV conditions had significantly better ratios than education. These findings suggest the 30 min version of IOOV is as effective as the 90 min standard.
