Gender Differences in Sexual Violence Perpetration Behaviors and Validity of Perpetration Reports: A Mixed-Method Study.

The current mixed-method study examined gender differences in sexual violence (SV) perpetration behaviors and the validity of perpetration reports made on the Sexual Experiences Survey-Short Form Perpetration (SES-SFP). Fifty-four university students (31 women and 23 men) were asked to think out loud while privately completing an online version of the SES-SFP and to describe (typed response) behaviors that they reported having engaged in on the SES. Those who reported no such behavior were asked to describe any similar behaviors they may have engaged in. Integration of the quantitative responses on the SES and the qualitative descriptions of the events reported showed that men's SV perpetration was more frequent and severe than women's. The qualitative event descriptions further suggested that men's verbal coercion was often harsher in tone and that men more often than women used physical force (including in events only reported as verbal coercion on the SES). Unlike men, women often reported that their response to a refusal was not intended to pressure their partner or obtain the sexual activity. Two women also mistakenly reported experiences of their own victimization or compliance (giving in to unwanted sex) on SES perpetration items, which inflated women's SV perpetration rate. Findings suggest that quantitative measurement can miss important qualitative differences in women and men's behaviors and may underestimate men's and overestimate women's SV perpetration. Participants also sometimes misinterpreted or described confusion around the SES items, suggesting a need for updated language on this and other quantitative measures.
