Strategies for Implementing GlobalConsent to Prevent Sexual Violence in University Men (SCALE): Study Protocol for a National Implementation Trial

Background: Globally, women 15-24 years are at heightened risk of sexual violence victimization, a risk factor for adverse mental, physical, and behavioral health outcomes. Sexual violence is common at universities and most often perpetrated by men, yet few evidence-based prevention strategies targeting men have been tested in low- and middle-income countries. GlobalConsent is a six-module, web-based educational program adapted from an efficacious U.S.-based program. Nine months post-treatment in a randomized trial in Vietnam, GlobalConsent reduced men's sexually violent behavior (Odds Ratio [OR] = 0.71, 95%CI 0.50-1.00) and increased prosocial intervening behavior (OR = 1.51, 1.00-2.28) relative to an attention-control. Evidence regarding optimal implementation strategies for scale up is needed.

Methods: We will randomize six medical universities in North, Central, and South Vietnam to deliver GlobalConsent using two different packages of implementation strategies that vary in intensity. Higher-intensity strategies will include greater 1) pre- and post-implementation engagement with university leaders and faculty, and 2) greater pre-implementation outreach, follow-up, and incentives for students to promote engagement and completion of GlobalConsent. Higher intensity universities will receive additional training and support for their added activities. We will compare implementation drivers and outcomes, intervention effectiveness, and cost-effectiveness across the two implementation bundles. Our mixed-methods comparative interrupted time-series design includes 1) qualitative interviews and quantitative surveys with university leaders and implementation teams to assess implementation barriers and facilitators; 2) repeated surveys with leaders and faculty, implementation teams, and male students to assess multilevel implementation drivers and outcomes, 3) repeated surveys with male students to assess behavioral outcomes (sexual violence and intervening behavior) and mediating variables (knowledge, attitudes, affect, and capacities), and 4) time diaries and cost tracking to assess cost effectiveness of the two implementation-strategies bundles.

Discussion: This project is the first to assess packages of implementation strategies to deliver an efficacious web-based sexual-violence-prevention program for undergraduate men across all regions of Vietnam and synergizes with a violence-prevention training initiative (D43TW012188). This approach will produce rigorous evidence about how to disseminate GlobalConsent nationally, which holds promise to reduce gender-based health inequities linked to sexual violence as GlobalConsent is brought to scale.
