Prevalence of Sexual Trauma History Using Behaviorally Specific Methods of Assessment in First Year College Students.

There are several challenges associated with evaluating the prevalence of sexual trauma, including child sexual abuse and adult sexual assault. The aim of this study was to assess sexual trauma prevalence rates among first year college students (N = 954) using behaviorally specific questions and a more representative recruitment sample that did not rely on self-selection. Participants completed a list of sexual trauma questions, including general questions containing labels such as "rape" or "abuse" as well as behaviorally specific questions that describe specific behaviors that qualify as sexual trauma without labels. Results indicated that 6.7% of the sample reported at least one incident of child sexual abuse, with similar rates for men and women. Women were more likely to report a history of adult sexual assault, which was reported by 12.4% of the total sample. Participants were also more likely to endorse a history of sexual trauma when answering behaviorally specific rather than general "label" questions. Women survivors in particular were more likely than men to identify their experiences as abuse/assault (66.7% versus 21.1% for child sexual abuse), which may help explain prevalence differences between men and women in prior research. Men may be less likely than women to label their experiences as abuse and may be underidentified in sexual trauma research without the use of behaviorally specific questions. Overall, the results of this study suggest that the prevalence of sexual trauma is better assessed using behaviorally specific questions and that this is an important topic of study among both men and women.
