An interventional study of Safe Bars active bystander training in Sexual Violence and Bystander Intervention, sponsored by RTI International. Recruiting at 3 sites in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-24.
Sponsored by RTI International · Not applicable, Interventional, and Prevention
The goal of this study is to evaluate the active bystander training provided by Safe Bars, Inc. and their local chapter organizations to staff at alcohol-serving establishments (e.g., bars). The training aims to improve norms about violence, create safer environments by teaching staff to intervene in potentially harmful situations, and help prevent sexual violence in the venue community. The study will examine the implementation and effectiveness of the training. The main questions it aims to answer are:
Researchers will compare staff and patron experiences at venues that have received the training with venues that are offered a delayed training. Staff and patron participants will be asked to complete surveys over about 12 months, research staff will conduct observations of training and observations in the venues, and selected venue managers and staff will be asked to complete individual interviews.
The prevalence of sexual violence (SV) is still unacceptably high in the United States and alcohol-serving venues (e.g., bars, nightclubs) are the most common public setting where SV occurs. Extensive research confirms that the venue environment, coupled with alcohol consumption, is associated with increased rates of SV. Trainings for venue staff, which combine bystander intervention skill-building with discussion of organization-level changes to policies, norms, and environmental characteristics, are a promising approach to prevent SV because they address both individual and community (i.e., venue)-level risk and protective factors. To date, these trainings have not been rigorously evaluated in terms of SV outcomes. There is a critical need to test the effectiveness of prevention approaches that change both individual behavior in venues and characteristics of venue settings to reduce SV among staff and patrons.
The proposed study will assess the effectiveness of Safe Bars active bystander training, which involves training and support for alcohol-serving venues, for primary prevention of SV. Safe Bars, Inc. has implemented trainings for venue staff since 2013, with 135 venues in 15 states trained either directly by Safe Bars, Inc. or by one of their trained chapter organizations since 2022. Grounded in established theories of behavior change, Safe Bars promotes anti-violence norms and creates safer environments by increasing bystander intervention among venue staff and generating venue-level solutions to preventing SV (such as improving policies or increasing anti-violence messaging in the venue).
In a prior study, the research team established the feasibility of evaluating venue-based SV prevention by conducting an evaluability assessment, including formative research and pilot testing of procedures. Informed by the results, the proposed evaluation uses a Hybrid Type 1 effectiveness-implementation design to assess the impact of Safe Bars training on SV among venue staff and patrons (Aim 1); examine venue environment characteristics, staff and patron psychosocial factors, and staff bystander intervention behaviors as mediators of Safe Bars training effects on SV outcomes (Aim 2); and examine potential moderating characteristics necessary for effective Safe Bars implementation and improved staff and patron outcomes (Aim 3). The study will use repeated surveys of patrons and staff at 15 intervention and 15 waitlist control venues, semi-structured interviews with managers and staff, training observations, venue observations, and Safe Bars implementation records to evaluate effectiveness and implementation and measure costs.
Safe Bars training is manualized for dissemination and has shown strong community acceptability. The outcomes of this study are expected to have an important positive impact by expanding the evidence base for community-level SV prevention and informing future implementation of venue-focused interventions.

Venues assigned to this arm will receive the Safe Bars active bystander training for their staff after baseline data collection for the study.
Behavioral: Safe Bars active bystander training
Venues assigned to this arm will be offered the Safe Bars active bystander training for their staff after the 6-month follow-up data collection for the study. They will not receive an intervention during the first 6 months of the study.
Behavioral: Safe Bars active bystander training
Safe Bars, Inc. (SBI)'s active bystander training is a primary prevention approach with three main components designed to (1) educate venue staff about the associations between alcohol and SV, (2) build bystander intervention skills and self-efficacy among venue staff, and (3) generate venue-level solutions to SV prevention. The 2.5-hour initial training combines didactic teaching with group brainstorming and practice-based role plays to teach staff actions they can take in response to risky scenarios observed in venue settings. Beyond increasing staff knowledge and skill, the training is also designed to spur venues' plans to support long-term culture change that reflects their local context and needs. After the initial training, SBI maintains a regular schedule of follow-up with trained venues to offer implementation support and access to SBI's other trainings in de-escalation and allyship.

Plan to share: Yes — Deidentified survey data from venue staff and patrons will be automatically archived after the study ends via the University of Florida's long-term electronic storage system, so it will be able to be made available to other researchers upon request with proper documentation of planned use and subsequent destruction. The data will be destroyed five years after the study ends. Participants' identifying information (names and contact information) will not be included in shared data.
