Reducing stigma in high school youth.

Abstract

We evaluated 21 contact-based education interventions in 5047 Canadian high school students and identified student characteristics associated with success. We used a one-group pretest/posttest design with standardized instruments to measure changes in behavioural intent. Variability across interventions was assessed using meta-analysis, and a mixed-effects logistic regression was used to identify student characteristics. Interventions were heterogeneous (I(2) =62.4%) but generally successful. The odds of getting an A grade was 2.57 times greater on the posttest than the pretest (95% CI=2.18, 3.03). Males were less likely to achieve a passing score overall; however, males who self-disclosed a mental illness were more likely to pass. Three percent of students experienced a large drop in social acceptance following the intervention. These were more likely to be male [OR=1.5 (95% CI=1.0, 2.1)]. Contact-based education is a promising practice for reducing stigma in high school students, although the field would benefit from fidelity criteria to reduce variation across interventions. Males and females react differently to antistigma programming; particularly those with self-reported mental illnesses and a small proportion may become more intolerant.
