Proposition 8 and Homophobic Bullying in California.

Abstract

Bias-based bullying is associated with negative outcomes for youth, but its contextual predictors are largely unknown. Voter referenda that target lesbian, gay, bisexual, and transgender groups may be 1 contextual factor contributing to homophobic bullying. Data come from 14 consecutive waves (2001-2014) of cross-sectional surveys of students participating in the California Healthy Kids Survey (<i>N</i> = 4 977 557). Student responses were aggregated to the school level (<i>n</i> = 5121). Using a quasi-experimental design, we compared rates of homophobic bullying before and after Proposition 8, a voter referendum that restricted marriage to heterosexuals in November 2008. Interrupted time series analyses confirmed that the academic year 2008-2009, during which Proposition 8 was passed, served as a turning point in homophobic bullying. The rate of homophobic bullying increased (<i>b</i> _linear = 1.15; <i>P</i> < .001) and accelerated (<i>b</i> _quadratic = 0.08; <i>P</i> < .001) in the period before Proposition 8. After Proposition 8, homophobic bullying gradually decreased (<i>b</i> _linear = -0.28; <i>P</i> < .05). Specificity analyses showed that these trends were not observed among students who reported that they were bullied because of their race and/or ethnicity, religion, or gender but not because of their sexual orientation. Furthermore, the presence of a protective factor specific to school contexts among lesbian, gay, bisexual, and transgender youth (gay-straight alliances) was associated with a smaller increase in homophobic bullying pre-Proposition 8. This research provides some of the first empirical evidence that public campaigns that promote stigma may confer risk for bias-based bullying among youth.
