Participant Acceptability of Questionnaires Impacts Sexual Victimization Prevalence Rates.

Obtaining accurate prevalence rates of sexual violence is made difficult by discrepancies in self-report questionnaires. Thus, the current study sought to explore participants' perceptions of acceptability (i.e., perceived difficulty and preference) as a potential mechanism of discrepancy between different questionnaires. Participants were 673 college students who completed two frequently used sexual victimization questionnaires, the Sexual Experiences Survey-Short Form Victimization (SES-SFV) and the Post-Refusal Sexual Persistence Scales-Victimization (PRSPS-V). Participants then answered questions about each measure's perceived difficulty and their preference between the two. Participants found the PRSPS-V easier to understand and preferred it 2.5 to 1 over the SES-SFV. Preference was related to reporting; participants who preferred the PRSPS-V reported more instances of sexual victimization on the PRSPS-V by 9.8%. Our results indicate that acceptability impacts reported prevalence rates and is one mechanism of discrepancy between questionnaires. Thus, researchers may wish to consider acceptability when choosing sexual victimization questionnaires.
