Menatti, A., Smyth, F. L., Teachman, B. A., & Nosek, B. A. (2013). Reducing stigma toward individuals with mental illnesses: A brief, online manipulation. *Stigma Research and Action*. **Abstract** **Purpose**: Our goal was to determine the effectiveness of a brief online intervention designed to reduce stigmarelevant attitudes toward mentally ill individuals. We examined whether the experience of completing a Brief Implicit Association Test (BIAT) measuring attitudes toward people with mental illnesses alters explicit stigma in two studies. **Methods**: In Study 1, participants completed the BIAT and received feedback about their individual level of implicit bias. Study 2 added a condition in which the BIAT was administered without feedback on performance. **Results**: Study 1 showed that the intervention was effective in reducing stigma-relevant attitudes toward mentally ill individuals. Study 2 showed that receiving feedback about one’s own implicit bias was not necessary for the intervention to reduce stigma. **Conclusion**: These studies show that the BIAT intervention may be effective at reducing explicit stigmatizing attitudes toward individuals with mental illnesses, at least in the short-term. Implications: This brief, accessible, and cost-effective stigma reduction strategy may be of use to community organizations whose mission is to address issues surrounding stigmatization in real-world settings.
