title: Population and Subgroup Differences in the Prevalence and Predictors of Campus Sexual Assault, United States, 2016-2021
title: Version 1

description: This secondary data analysis included analyzing pre and post-test intervention data from the Sexual Assault Prevention for Undergraduates (SAPU) online sexual assault prevention education program.
The SAPU data included a large, demographically diverse national sample of college students, allowing for a more in-depth investigation of the prevalence and predictors of sexual assault victimization and perpetration across different types of college campuses. Furthermore, the dataset included contemporaneous measures of unwanted sexual contact victimization and perpetration, dating abuse victimization, and harassment victimization.

The aims for the study included the following:

Aim 1: Examine variation in school-level prevalence of sexual assault victimization and perpetration by school type, size, and region from academic years (AY) 2016-2017 to 2019-2020.
Aim 2: Assess subgroup differences (by gender identity, sexual orientation, race) in school-level prevalence of sexual assault victimization and perpetration, accounting for school type, size, region.
Aim 3: Investigate the relationship between attitudes and perceptions of campus norms and self-reports of sexual assault victimization and perpetration, accounting for precampus sexual assault and individual demographics and school characteristics (type, size, region).
Aim 4: Examine variation in the relationship between attitudes and perceptions of campus norms and self-reports of sexual assault victimization and perpetration by subgroups (gender identity, sexual orientation, race), accounting for precampus sexual assault and individual and school characteristics (type, size, region).
Aim 5: Examine variation in bystander intentions, efficacy, and behaviors and self-reports of sexual assault victimization and perpetration by subgroups (gender identity, sexual orientation, race), accounting for attitudes, perceptions of campus norms, and precampus sexual assault, as well as individual and school characteristics (type, size, region).
description: The purpose of this study was to investigate the prevalence and predictors of sexual assault victimization and perpetration across college campuses.
description: The secondary analysis of this study included a partnership with Vector Solutions, which manages the Sexual Assault Prevention for Undergraduates (SAPU) online prevention program. The SAPU dataset consisted of pre and post-intervention data. Students from nearly 400 schools within all 50 states of the U.S. were included. Most participants were on campuses that require freshman, transfer, and new graduate students to complete the program prior to matriculation. Students completed pre-intervention (T1) and post-intervention (T2) surveys. Students completed the pre-intervention survey before accessing SAPU content, typically prior to the time they arrived on campus for their first year. After completion, and generally after they have started the fall semester, students were invited to complete the T2 survey.
description: The referenced data included measures of unwanted sexual
contact victimization, dating abuse victimization, harassment victimization, and unwanted sexual contact perpetration, as well as measures of campus social norms, attitudes, and bystander behavior.
description: The Sexual Assault Prevention for Undergraduates (SAPU) program included public and private institutions and two year and four year colleges with varying sizes of enrollment. SAPU data are collected annually each academic year:

For the Academic year of 2020-2021, the participant sample size was 670,855.
For the Academic year of 2019-2020, the participant sample size was 773,102.
For the Academic year of 2018-2019, the participant sample size was 660,822.
For the Academic year of 2017-2018, the participant sample size was 915,387.
For the Academic year of 2016-2017, the participant sample size was 666,571.
