OBJECTIVES: This pilot study describes an evaluation of the Bringing in the Bystander (BITB) in-person program conducted with United States Army Europe personnel. METHODS: The sample was comprised of 394 soldiers (29% participated in and 71% had not participated in the BITB program). Data were analyzed 4V2 months after the program was presented. RESULTS: Compared to the soldiers who did not participate in the program, soldiers who participated in the program were significantly more likely to report that they had engaged in one or more of the 117 behaviors, that they had helped an acquaintance or a stranger, and that they had taken action when they saw sexual assault or stalking occurring, about to occur or after it had occurred. CONCLUSIONS: The results indicate that with thoughtful and appropriate modifications, the BITB in-person prevention program, initially developed for a college audience, can be transferred to a military audience.
