The Prospective Influence of Perceived Social Norms on Bystander Actions Against Sexual Violence and Relationship Abuse: A Multiple Mediation Model.

The present study assessed support for an innovative model of the direct and indirect paths through which perceived peer norms regarding the prevalence and acceptability of sexual violence (SV) and relationship abuse (RA) may influence the decisional process leading to bystander intervention. Analyses included baseline and 6-month follow-up data collected from a large sample of high school students ( = 2,303) across 27 schools in the Northeastern United States. Path analyses were conducted to test a multiple mediation model of the direct and indirect associations among the sequential predictors of perceived descriptive and injunctive norms, personal attitudes, abuse perceptions, risk recognition, and dependent measures of bystander behaviors at baseline and 6-month follow-up. Higher perceptions of the prevalence (descriptive norms) and acceptability (injunctive norms) of SV and RA among peers were associated with more accepting personal attitudes toward SV and RA, which were associated with lower abuse perceptions and risk recognition. Furthermore, lower abuse perceptions and risk recognition were associated with decreases in bystander behaviors at both time points. Mediational analyses revealed several significant indirect paths through which higher perceptions of descriptive and injunctive norms contributed to decreases in bystander behavior. Findings provide novel evidence of the prospective influence of perceived norms on bystander intervention behavior in situations of SV and RA.
