Rigorous evidence of the effectiveness of male engagement interventions, particularly on how these interventions impact relationship power dynamics and women’s decision-making, remains limited. This study assessed the impact of the Bandebereho gender-transformative couples’ intervention on impact on multiple behavioral and health-related outcomes influenced by gender norms and power relations. We conducted a multi-site randomised controlled trial in four Rwandan districts with expectant/current fathers and their partners, who were randomised to the intervention (n = 575 couples) or control group (n = 624 couples). Primary outcomes include women’s experience of physical and sexual IPV, women’s attendance and men’s accompaniment at ANC, modern contraceptive use, and partner support during pregnancy. At 21-months post-baseline, 1123 men and 1162 partners were included in intention to treat analysis. Generalized estimating equations with robust standard errors were used to fit the models. The Bandebereho intervention led to substantial improvements in multiple reported outcomes. Compared to the control group, women in the intervention group reported: less past-year physical (OR 0.37, p<0.001) and sexual IPV (OR 0.34, p<0.001); and greater attendance (IRR 1.09, p<0.001) and male accompaniment at antenatal care (IRR 1.50, p<0.001); and women and men in the intervention group reported: less child physical punishment (women: OR 0.56, p = 0.001; men: OR 0.66, p = 0.005); greater modern contraceptive use (women: OR 1.53, p = 0.004; men: OR 1.65, p = 0.001); higher levels of men’s participation in childcare and household tasks (women: beta 0.39, p<0.001; men: beta 0.33, p<0.001); and less dominance of men in decision-making. Our study strengthens the existing evidence on male engagement approaches; together with earlier studies our findings suggest that culturally adapted gender-transformative interventions with men and couples can be effective at changing deeply entrenched gender inequalities and a range of health-related behavioral outcomes.

This study assesses the role of gender norms on the relationship between adverse childhood experiences (ACEs) and peer-violence perpetration among very young adolescents in three urban poor cities of Indonesia. A cross-sectional study was conducted in Bandar Lampung, Denpasar, and Semarang in Indonesia. A total of 2,974 participants (boys: 44.79%, girls: 55.21%) between 10 and 14 years were included in the analysis. Logistic regression, mediation, and moderation analyses were conducted stratified by sex. Risk factors of peer-violence perpetration among boys and girls included three (boys: adjusted odds ratio [aOR] 2.51, 95% confidence interval [CI] 1.32-4.75; girls: aOR 1.82, 95% CI .95-3.52) and four or more (boys: aOR 6.75, 95% CI 3.86-11.80; girls: aOR 5.37, 95% CI 3.07-9.37) history of ACE. Risk factors of peer-violence perpetration among boys included having inequitable sexual double standard (SDS) indices (aOR 1.46, 95% CI 1.09-1.95). SDS measures the perception boys are rewarded for romantic relationship engagement, whereas girls are stigmatized or disadvantaged for the experience. Other risk factors included lifetime tobacco use among boys and girls and lifetime alcohol use among boys. Protective factors included parental closeness among girls. Based on the research in three Indonesian communities, this study demonstrates that boys are disproportionately exposed to adversities including history of ACE, inequitable SDS, lifetime alcohol use and tobacco use in comparison to girls. Programs targeting ACE and gender norms which engage boys, girls, and families are more likely to be successful in reducing peer-violence perpetration and promoting gender equitable norms.

Most impact evaluations of intimate partner violence (IPV) prevention interventions use binary measures of “any” versus “no” physical and/or sexual IPV as their primary outcome measure, missing opportunities to capture nuance. In this study, we reanalyzed secondary data from six randomized controlled trials conducted in low- and middle-income countries—Bandebereho (Rwanda), Becoming One (Uganda), Indashyikirwa (Rwanda), MAISHA CRT01, MAISHA CRT02 (Tanzania), Stepping Stones Creating Futures (South Africa), and Unite for a Better Life (Ethiopia), to assess how different conceptualizations and coding of IPV variables can influence interpretations of the impact of an intervention. We compared the standard outcome measures to new measures that reflect the severity and intensity of violence and whether interventions prevent new cases of IPV or reduce or stop ongoing violence. Results indicate that traditional binary indicators masked some of the more subtle intervention effects, and the use of the new indicators allowed for a better understanding of the impacts of the interventions. Conclusions on whether a program is perceived “to work” are highly influenced by the IPV outcomes that the investigators choose to report, and how they are measured and coded. Lack of attention to outcome choice and measurement could lead to prematurely abandoning strategies useful for violence reduction or missing essential insights into how programs may or may not affect IPV. While these results must be interpreted cautiously, given differences in intervention types, the underlying prevalence of violence, sociodemographic factors, sample sizes, and other contextual differences across the trial sites, they can help us move toward a new approach to reporting multiple outcomes that allow us to unpack the “impact” of an intervention by assessing intervention effect by the severity of violence and type of prevention, whether primary and secondary.

Curriculum-based programs are one of the most common and effective strategies for preventing intimate partner violence (IPV) in low and middle-income countries (LMICs). Yet relatively little is known about how curricula and their implementation compare across programs, limiting learning and innovation. This scoping review examined the design, content, and implementation of 55 curricula from 42 programs implemented in 23 LMICs between 2001 and 2024. Curricula were identified through screening systematic reviews, grey literature, donor reports, and professional contacts. Data on program characteristics, subject matter, methodologies, and implementation were extracted, synthesized, and analyzed. We found curricula employed similar participatory methodologies and content, and violence, gender, relationships, power, and communication emerged as core topics. Adaptation of earlier programming was widespread: only five curricula did not cite content adapted from an earlier program. Key gaps included the relatively limited use of evidence-based strategies to build relationship skills and content addressing alcohol use and poor mental health, important IPV risk factors. Implementation varied considerably in terms of intensity, frequency, duration, group size, facilitators and their training, and information on some features was sparse. The findings highlight several opportunities for strengthening and innovation, for which we present six recommendations to guide future IPV prevention programming.
