The Causal Influence of Perceived Social Norms on Intimate Partner Violence Perpetration: Converging Cross-Sectional, Longitudinal, and Experimental Support for a Social Disinhibition Model
Across three studies, we develop a model of the direct and indirect paths through which the perceived prevalence (perceived descriptive norms [PDN]) of intimate partner violence (IPV) among peers may influence individuals’ likelihood of engaging in IPV. Study 1 replicated and extended previous cross-sectional research by demonstrating a positive longitudinal association between PDN and subsequent IPV perpetration. Study 2 further showed the influence of PDN on IPV perpetration to be mediated through its relation to perceived peer acceptance of IPV (perceived injunctive norms [PIN]), which in turn predicted personal IPV acceptance. Study 3 built on this model using an experimental paradigm to show that increasing PDN leads to corresponding increases in PIN and, in turn, personal IPV acceptance, which both predicted IPV perpetration. Furthermore, the effects of PIN on personal IPV acceptance and IPV propensity were strongest for dominance-oriented individuals. Results bear important implications for social norms–based interventions for IPV.
