Abstract
What solutions can we find in the research literature for preventing sexual violence, and what psychological theories
have guided these efforts? We gather all primary prevention efforts to reduce sexual violence from 1985 to 2018 and
provide a bird’s-eye view of the literature. We first review predominant theoretical approaches to sexual-violence
perpetration prevention by highlighting three interventions that exemplify the zeitgeist of primary prevention efforts at
various points during this time period. We find a throughline in primary prevention interventions: They aim to change
attitudes, beliefs, and knowledge (i.e., ideas) to reduce sexual-violence perpetration and victimization. Our meta-analysis
of these studies tests the efficacy of this approach directly and finds that although many interventions are successful at
changing ideas, behavior change does not follow. There is little to no relationship between changing attitudes, beliefs,
and knowledge and reducing victimization or perpetration. We also observe trends over time, including a shift from
targeting a reduction in perpetration to targeting an increase in bystander intervention. We conclude by highlighting
promising new strategies for measuring victimization and perpetration and calling for interventions that are informed
by theories of behavior change and that center sexually violent behavior as the key outcome of interest.
