The effectiveness of the Bringing in the Bystander™ program among first-year students at a religiously-affiliated liberal arts college

To address sexual assault, many universities are implementing Bringing in the Bystander™ (BitB) training, a prevention program that aims to improve participants’ bystander self-efficacy and reduce rape myth acceptance. Although growing evidence supports the efficacy of BitB, data primarily have been amassed at one large public university, the University of New Hampshire, limiting the generalizability of intervention effectiveness. To address this gap, we made modifications to training structure and assessed BitB effectiveness among first-year students at a private Jesuit Catholic liberal arts college in Massachusetts. Using a within-subjects pre-/post-test survey design, we found that students’ (N = 164) bystander self-efficacy significantly increased and rape myth acceptance significantly decreased following training. Results indicate that BitB implementation is feasible and effective on a new campus despite modest modifications to training delivery and despite differences in religious affiliation, median income, and class size between the two campuses.
