RESUMO
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.

Rape myths-false but widely held beliefs that serve to deny and justify sexual aggression-present a major barrier to reporting and prevention of sexual violence in Vietnam and globally. Based on a parent study aimed at reducing sexual violence at two universities in Hanoi, we developed and assessed a contextualized measure of rape myths among young people in Vietnam. Items from previously validated rape myth acceptance (RMA) scales and data from qualitative research informed the development of 50 items, which were administered to Vietnamese 18-24-year-olds (n = 2,756 total, n = 1,798 cisgender women) via an anonymous link in February 2021. We used factor analysis to explore and test factor structure and multi-group factor analysis to assess measurement equivalence across gender. We calculated item-level discrimination and difficulty parameters and visualized information curves using item response theory analysis, informing the development of a short form. Four hypothesized subconstructs identified in the qualitative data emerged as factors: (1) "He didn't mean to"; (2) "She asked for it"; (3) "It wasn't really rape"; and (4) "Rape is a deviant event." A fifth factor, "She didn't protect herself," included four items from formative data. Confirming formative findings and prior literature, cisgender women had lower RMA than cisgender men, particularly on items related to victim-blaming. The Vietnamese Rape Myths Acceptance Scales were internally consistent and equivalent between cisgender men and women, capturing elements specific to the Vietnamese context and providing a tool for campus climate surveys and evaluations of sexual violence prevention programs.

BACKGROUND: Sexual violence against women is prevalent worldwide. Prevention programs that treat men as allies and integrate a bystander framework are emerging in lower income settings, but evidence of their effectiveness is conflicting. OBJECTIVE: This study aimed to test the impact of GlobalConsent on sexually violent behavior and prosocial bystander behavior among university men in Vietnam. METHODS: We used a double-blind, parallel intervention versus control group design with 1:1 randomization at 2 universities. A total of 793 consenting heterosexual or bisexual men aged 18-24 years who matriculated in September 2019 were enrolled and assigned randomly to GlobalConsent or an attention-control adolescent health education (AHEAD) program. GlobalConsent is an adapted, theory-based, 6-module web-based intervention with diverse behavior change techniques and a locally produced serial drama. AHEAD is a customized, 6-module attention-control program on adolescent health. Both the programs were delivered to computers and smartphones over 12 weeks. Self-reported sexually violent behaviors toward women in the prior 6 months and prosocial bystander behaviors in the prior year were measured at 0, 6, and 12 months. RESULTS: More than 92.7% (735/793) of men in both study arms completed at least 1 program module, and >90.2% (715/793) of men completed all 6 modules. At baseline, a notable percentage of men reported any sexually violent behavior (GlobalConsent: 123/396, 31.1%; AHEAD: 103/397, 25.9%) in the prior 6 months. Among men receiving GlobalConsent, the odds of reporting a high level (at least 2 acts) of sexually violent behavior at the endline were 1.3 times the odds at baseline. Among men receiving AHEAD, the corresponding odds ratio was higher at 2.7. The odds of reporting any bystander behavior at endline were 0.7 times the odds at baseline for GlobalConsent, and the corresponding odds ratio for AHEAD was lower at 0.5. CONCLUSIONS: Compared with a health attention-control condition, GlobalConsent has sustained favorable impacts on sexually violent behavior and prosocial bystander behavior among matriculating university men in Vietnam, who would otherwise face increasing risks of sexually violent behavior. GlobalConsent shows promise for national scale-up and regional adaptations. TRIAL REGISTRATION: ClinicalTrials.gov NCT04147455; https://clinicaltrials.gov/ct2/show/NCT04147455.

Sexual violence remains a global problem that disproportionately affects women. Though sexual violence interventions exist, few have been implemented in low- or middle-income countries, and none in Vietnam for young men. We adapted a sexual violence prevention intervention (RealConsent) developed for college men in the U.S. and conducted a randomized controlled trial of the adapted intervention (GlobalConsent) with college men in Vietnam. We assessed the effects of GlobalConsent on sexually violent behavior and prosocial bystander behavior, directly and through theoretically targeted mediators. The study design entailed a double-blind, parallel intervention-control-group design in two universities. Consenting heterosexual or bisexual men 18-24 years starting university in September 2019 (n = 793) completed a baseline survey and were assigned with 1:1 randomization to GlobalConsent or attention control. Both programs were web-based and lasted 12 weeks. Path analysis was performed to study the mediating effects of cognition/knowledge, beliefs/attitudes, affect, and efficacy/intention variables measured at six months on sexually violent behavior and prosocial bystander behavior measured at 12 months. In parallel multiple-mediator models, initiating GlobalConsent lowered the odds of sexually violent behavior mainly indirectly, via knowledge of sexual violence legality and harm and victim empathy and increased the odds of prosocial bystander behavior directly and indirectly, through knowledge of sexual violence legality and harm and bystander capacities. The efficacious direct and indirect effects of GlobalConsent support the cross-cultural applicability of its underlying theory of change and findings from mediation analyses of its sister program RealConsent, suggesting GlobalConsent's national scalability and adaptability across Southeast Asia.

BACKGROUND: Adolescence and emerging adulthood represent a period of heightened vulnerability to sexual violence (SV). While some research suggests that exposure to sexually explicit material (SEM) among adolescents and college students is associated with sexually violent behavior, our understanding of this relationship is limited. This study aimed to assess the relationship between prior exposure to several types of SEM and sexually violent behavior in a sample of first-year university men in Vietnam. METHODS AND FINDINGS: A cohort of 739 first-year male university students completed three survey waves over 14 months, providing information on contact and non-contact sexually violent behavior, exposure to SEM, and other theorized confounders of the SEM-SV relationship. Controlling for these covariates, we estimated the average treatment effect of SEM on contact and non-contact SV using the propensity score method. We also conducted a dose-response analysis for the effect of violent SEM on SV based on frequency-of-exposure classes derived from latent class analysis. The majority of the sample reported exposure to SEM in the prior six months, with 41% of the sample reporting exposure to violent SEM. In propensity-adjusted models, exposure to violent SEM, but not other types, had a small but significant positive effect on contact and non-contact SV. These effects increased for frequent viewers of violent SEM. Models of contact SV showed endogeneity, warranting caution. CONCLUSIONS: Exposure to violent SEM is prevalent among university men in Vietnam and may be contributing to sexually violent behavior. Incorporating media literacy into SV prevention programs to mitigate these potential effects may be warranted.

Background: Sexual violence against women remains a global public health problem, with Southeast Asia having among the highest rates of violence victimization globally. Exposure to violence in adolescence--a highly prevalent experience in Vietnam--is associated with later perpetration of violence against others. However, childhood maltreatment as a latent construct is understudied, with most analyses focusing on theoretical categories, potentially missing key patterns of victimization, particularly poly-victimization. Poor understanding of these experience limits researchers' ability to predict and intervene upon cyclical perpetration of violence. This study aims to identify latent classes of childhood maltreatment, and to test associations between class membership and sexually violent behavior during the first 12 months of university in a sample of Vietnamese men. Methods and findings: Heterosexual and bisexual men aged 18-24 matriculating into two universities in Hanoi were recruited for the randomized controlled trial of GlobalConsent, a six-module online sexual-violence prevention program. Participants (N = 793) completed a baseline survey, were randomized 1:1 to GlobalConsent or attention control, and were invited to complete post-test surveys at six-months post-baseline and 12-months post-baseline. Validated scales were employed to assess childhood maltreatment and past-six-month sexually violent behavior at each post-test. Latent class analysis identified four classes of childhood maltreatment: Limited-to-no, physical, physical and emotional, and poly-victimization. Associations between childhood maltreatment class and sexually violent behavior demonstrate a threshold effect, wherein poly-victimized men were significantly more likely than men in other classes to have engaged in sexually violent behavior during the 12-month follow-up period. Conclusions: There is a vital need for screening and intervention with men who have experienced childhood maltreatment in Vietnam to prevent future violence perpetration. Education is needed to break the cycle of violence intergenerationally and in romantic relationships by changing harmful norms around men's sexual privilege and the normalization of childhood maltreatment.
RESUMO
Global health partnerships (GHPs) involve complex relationships between individuals and organizations, often joining partners from high-income and low- or middle-income countries around work that is carried out in the latter. Therefore, GHPs are situated in the context of global inequities and their underlying sociopolitical and historical causes, such as colonization. Equity is a core principle that should guide GHPs from start to end. How equity is embedded and nurtured throughout a partnership has remained a constant challenge. We have developed a user-friendly tool for valuing a GHP throughout its lifespan using an equity lens. The development of the EQT was informed by 5 distinct elements: a scoping review of scientific published peer-reviewed literature; an online survey and follow-up telephone interviews; workshops in Canada, Burkina Faso, and Vietnam; a critical interpretive synthesis; and a content validation exercise. Findings suggest GHPs generate experiences of equity or inequity yet provide little guidance on how to identify and respond to these experiences. The EQT can guide people involved in partnering to consider the equity implications of all their actions, from inception, through implementation and completion of a partnership. When used to guide reflective dialogue with a clear intention to advance equity in and through partnering, this tool offers a new approach to valuing global health partnerships. Global health practitioners, among others, can apply the EQT in their partnerships to learning together about how to cultivate equity in their unique contexts within what is becoming an increasingly diverse, vibrant, and responsive global health community.

Social norms surrounding sex and relationships remain gendered among young people in Vietnam, with men maintaining a privileged role in heterosexual relationships. This analysis explored how university students in Vietnam perceived prevailing gender norms, and how these norms influenced men's understanding of sexual consent in dating relationships. This analysis drew primarily on in-depth interviews with heterosexual men and secondarily from interviews with women attending two universities in Hanoi in 2018. Thematic analysis of the interviews revealed a broader narrative about how prevailing gender norms shape men's dating behaviour and beliefs about consent. Participants expected young men to be independent and decisive. Men were seen as free to initiate dating and sexual encounters. Some participants expected young women to be accommodating in dating relationships, although acceptable relationships for women were restricted, and premarital sex was a reputational risk. Most participants described cues for consent and non-consent for sex; however, dismissal of women's refusals, and normalised sexual coercion were common. Among university men in Hanoi, gender norms privileging men and growing expectations of premarital sex may be normalising sexual coercion in dating relationships. University educational programmes are needed to promote equitable gender norms, affirmative sexual consent and expanded definitions of sexual coercion.

BACKGROUND: Sexual violence-any sexual act committed against a person without freely given consent-disproportionately affects women. Women's first experiences of sexual violence often occur in adolescence. In Asia and the Pacific, 14% of sexually experienced adolescent girls report forced sexual debut. Early prevention with men that integrates a bystander framework is one way to address attitudes and behavior while reducing potential resistance to participation. METHODS: This paper describes a study protocol to adapt RealConsent for use in Vietnam and to test the impact of the adapted program-GlobalConsent-on cognitive/attitudinal/affective mediators, and in turn, on sexual violence perpetration and prosocial bystander behavior. RealConsent is a six-session, web-based educational entertainment program designed to prevent sexual violence perpetration and to enhance prosocial bystander behavior in young men. The program has reduced the incidence of sexual violence among men attending an urban, public university in the Southeastern United States. We used formative qualitative research and the Centers for Disease Control and Prevention's Map of the Adaptation Process to adapt RealConsent. We conducted semi-structured interviews with college men (n = 12) and women (n = 9) to understand the social context of sexual violence. We conducted focus group discussions with university men and stakeholders (n = 14) to elicit feedback on the original program. From these data, we created scripts in storyboard format of the adapted program. We worked closely with a small group of university men to elicit feedback on the storyboards and to refine them for acceptability and production. We are testing the final program-GlobalConsent-in a randomized controlled trial in heterosexual or bisexual freshmen men 18-24 years attending two universities in Hanoi. We are testing the impact of GlobalConsent (n = 400 planned), relative to a health-education attention control condition we developed (n = 400 planned), on cognitive/attitudinal/affective mediators, prosocial bystander behavior, and sexual violence perpetration. DISCUSSION: This project is the first to test the impact of an adapted, theoretically grounded, web-based educational entertainment program to prevent sexual violence perpetration and to promote prosocial bystander behavior among young men in a middle-income country. If effective, GlobalConsent will have exceptional potential to prevent men's sexual violence against women globally.

In lower-income settings, women more often than men justify intimate partner violence (IPV). Yet, the role of measurement invariance across gender is unstudied. We developed the ATT-IPV scale to measure attitudes about physical violence against wives in 1,055 married men and women ages 18-50 in My Hao district, Vietnam. Across 10 items about transgressions of the wife, women more often than men agreed that a man had good reason to hit his wife (3 % to 92 %; 0 % to 67 %). In random split-half samples, one-factor exploratory factor analysis (EFA) (N 1 = 527) and confirmatory factor analysis (CFA) (N 2 = 528) models for nine items with sufficient variability had significant loadings (0.575-0.883; 0.502-0.897) and good fit (RMSEA = 0.068, 0.048; CFI = 0.951, 0.978, TLI = 0.935, 0.970). Three items had significant uniform differential item functioning (DIF) by gender, and adjustment for DIF revealed that measurement noninvariance was partially masking men's lower propensity than women to justify IPV. A CFA model for the six items without DIF had excellent fit (RMSEA = 0.019, CFI = 0.994, TLI = 0.991) and an attitudinal gender gap similar to the DIF-adjusted nine-item model, suggesting that the six-item scale reliably measures attitudes about IPV across gender. Researchers should validate the scale in urban Vietnam and elsewhere and decompose DIF-adjusted gender attitudinal gaps.

PURPOSE: We assess the association of men's exposure to violence in childhood-witnessing physical violence against one's mother and being hit or beaten by a parent or adult relative-with their attitudes about intimate partner violence (IPV) against women. We explore whether men's perpetration of IPV mediates this relationship and whether men's attitudes about IPV mediate any relationship of exposure to violence in childhood with perpetration of IPV. METHODS: Five hundred twenty-two married men 18-51 years in Vietnam were interviewed. Multivariate regressions for ordinal and binary responses were estimated to assess these relationships. RESULTS: Compared with men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of reporting more reasons to hit a wife (aOR, 1.43; 95% CI, 1.03-2.00 and aOR, 1.66; 95% CI, 1.05-2.64, respectively). Men's lifetime perpetration of IPV accounted fully for these associations. Compared with men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of ever perpetrating IPV (aOR, 3.28; 95% CI, 2.15-4.99 and aOR, 4.56; 95% CI, 2.90-7.17, respectively). Attitudes about IPV modestly attenuated these associations. CONCLUSIONS: Addressing violence in childhood is needed to change men's risk of perpetrating IPV and greater subsequent justification of it.

Attitudes about intimate partner violence (IPV) against women are widely surveyed, but attitudes about women's recourse after exposure to IPV are understudied, despite their importance for intervention. Designed through qualitative research and administered in a probability sample of 1,054 married men and women 18 to 50 years in My Hao District, Vietnam, the ATT-RECOURSE scale measures men's and women's attitudes about a wife's recourse after exposure to physical IPV. Data were initially collected for nine items. Exploratory factor analysis (EFA) with one random split-half sample (N 1 = 526) revealed a one-factor model with significant loadings (0.316-0.686) for six items capturing a wife's silence, informal recourse, and formal recourse. A confirmatory factor analysis (CFA) with the other random split-half sample (N 2 = 528) showed adequate fit for the six-item model and significant factor loadings of similar magnitude to the EFA results (0.412-0.669). For the six items retained, men consistently favored recourse more often than did women (52.4%-66.0% of men vs. 41.9%-55.2% of women). Tests for uniform differential item functioning (DIF) by gender revealed one item with significant uniform DIF, and adjusting for this revealed an even larger gap in men's and women's attitudes, with men favoring recourse, on average, more than women. The six-item ATT-RECOURSE scale is reliable across independent samples and exhibits little uniform DIF by gender, supporting its use in surveys of men and women. Further methodological research is discussed. Research is needed in Vietnam about why women report less favorable attitudes than men regarding women's recourse after physical IPV.

OBJECTIVE: To assess human papillomavirus (HPV) vaccination coverage after demonstration projects conducted in India, Peru, Uganda and Viet Nam by PATH and national governments and to explore the reasons for vaccine acceptance or refusal. METHODS: Vaccines were delivered through schools or health centres or in combination with other health interventions, and either monthly or through campaigns at fixed time points. Using a two-stage cluster sample design, the authors selected households in demonstration project areas and interviewed over 7000 parents or guardians of adolescent girls to assess coverage and acceptability. They defined full vaccination as the receipt of all three vaccine doses and used an open-ended question to explore acceptability. FINDINGS: Vaccination coverage in school-based programmes was 82.6% (95% confidence interval, CI: 79.3-85.6) in Peru, 88.9% (95% CI: 84.7-92.4) in 2009 in Uganda and 96.1% (95% CI: 93.0-97.8) in 2009 in Viet Nam. In India, a campaign approach achieved 77.2% (95% CI: 72.4-81.6) to 87.8% (95% CI: 84.3-91.3) coverage, whereas monthly delivery achieved 68.4% (95% CI: 63.4-73.4) to 83.3% (95% CI: 79.3-87.3) coverage. More than two thirds of respondents gave as reasons for accepting the HPV vaccine that: (i) it protects against cervical cancer; (ii) it prevents disease, or (iii) vaccines are good. Refusal was more often driven by programmatic considerations (e.g. school absenteeism) than by opposition to the vaccine. CONCLUSION: High coverage with HPV vaccine among young adolescent girls was achieved through various delivery strategies in the developing countries studied. Reinforcing positive motivators for vaccine acceptance is likely to facilitate uptake.

Using a couple-centered approach, this study focuses on the relative attributes and attitudes of spouses as predictors of marital violence. Analysis of data from Vietnam showed that 37% of married women have ever been hit by their husbands. Regression results found that husbands with lower resources or status than their wives were more likely to have abused. Results also found that the association between husbands' gender attitudes and marital violence depends on the level of equity of wives'attitudes. The decline in violence among couples in which husbands expressed gender equitable attitudes was greater when wives also expressed equitable attitudes.

OBJECTIVE: To report on the use of lot quality-assurance sampling (LQAS) surveys undertaken within an area-sampling framework to identify priority areas for intervention with trachoma control activities in Viet Nam. METHODS: The LQAS survey method for the rapid assessment of the prevalence of active trachoma was adapted for use in Viet Nam with the aim of classifying individual communes by the prevalence of active trachoma among children in primary school. School-based sampling was used; school sites to be sampled were selected using an area-sampling approach. A total of 719 communes in 41 districts in 18 provinces were surveyed. FINDINGS: Survey staff found the LQAS survey method both simple and rapid to use after initial problems with area-sampling methods were identified and remedied. The method yielded a finer spatial resolution of prevalence than had been previously achieved in Viet Nam using semiquantitative rapid assessment surveys and multistage cluster-sampled surveys. CONCLUSION: When used with area-sampling techniques, the LQAS survey method has the potential to form the basis of survey instruments that can be used to efficiently target resources for interventions against active trachoma. With additional work, such methods could provide a generally applicable tool for effective programme planning and for the certification of the elimination of trachoma as a blinding disease.
