Global measurement of intimate partner violence to monitor Sustainable Development Goal 5.

BACKGROUND: One third of women experience intimate partner violence (IPV) and potential sequelae. Sustainable Development Goal (SDG) 5.2-to eliminate violence against women, including IPV-compels states to monitor such violence. We conducted the first global measurement-invariance assessment of standardised item sets for IPV. METHODS: Demographic and Health Surveys (DHS) from 36 Lower-/Middle-Income Countries (LMICs) administering 18 IPV items during 2012-2018 were included. Analyses were performed separately for two items sets: lifetime physical IPV (seven items) and controlling behaviours (five items). We performed country-specific exploratory and confirmatory factor analyses (EFA/CFA). Datasets meeting benchmarks for acceptable item loadings and model-fit statistics were included in multiple-group CFA (MGCFA) to test for exact measurement invariance. Based on findings, alignment optimization (AO) was performed to assess approximate measurement invariance (< 25% of model parameters non-invariant). For each item set, national rankings based on AO-derived scores and on prevalence estimates were compared. AO-derived scores were correlated with type-specific IPV prevalences to assess correspondence. RESULTS: National rates of physical IPV (5.6-50.5%) and controlling behavior (25.9-84.7%) varied. For each item set, item loadings and model-fit statistics were adequate in country-specific, unidimensional EFAs and CFAs. Both unidimensional constructs lacked exact invariance in MGCFA but achieved approximate invariance in AO analysis (12.3% of model parameters for physical IPV and 6.7% for controlling behaviour non-invariant). For both item sets, national rankings based on AO-derived scores were distributed similarly to rankings based on prevalence. However, estimates often were not significantly different cross-nationally, precluding national-level comparisons regardless of estimation strategy. Three physical-IPV items (slap, twist, choke) and two controlling-behaviour items (meet female friends; contact with family) warrant cognitive testing to improve their psychometric properties. Correlations of AO-derived scores for physical IPV (0.48-0.66) and controlling behaviours (0.49-0.87) with prevalences of lifetime physical, sexual, psychological IPV as well as controlling behaviour varied. CONCLUSIONS: Seven DHS lifetime physical-IPV items and five DHS controlling-behaviour items were approximately invariant across 36 LMICs spanning five world regions, such that cross-national comparisons of factor means are reasonable. Measurement-invariance testing over time will inform their utility to monitor SDG5.2.1; cross-national, cross-time measurement-invariance testing of improved sexual and psychological IPV item-sets is needed.

Do laws promoting gender equity and freedom from violence benefit the most vulnerable? A multilevel analysis of women's and adolescent girls' experiences in 15 low- and-middle-income countries.

In this analysis, we assess whether laws that promote gender equity and freedom from violence are associated with a lower risk of prior-year physical and sexual intimate partner violence (IPV) among adolescent girls and adult women (AGW) and whether these laws protect more and less vulnerable AGW equally. We included all 15 countries that administered the Domestic Violence Module in a Demographic and Health Survey since 2015. The primary exposure was a validated, country-level index of laws on violence against women and girls (LoVI). A multilevel approach was used to model five forms of violence (prior-year partner physical, sexual, physical or sexual violence and prior-year non-partner physical violence or sexual violence) among ever-partnered, non-widowed adolescent girls 13-19 years (n = 6691) and women 20-49 years (n = 119 343). Across countries, partner physical violence ranged from 0% to 33% and sexual violence from 0% to 23%. Laws on marital rape, child marriage and sexual harassment were negatively associated with prior-year physical and sexual IPV for women and girls. Comprehensive domestic violence legislation was unrelated to girls' experiences of prior-year physical or prior-year sexual IPV. No interaction was observed between LoVI component laws and a score meant to capture adolescent vulnerability. Three of the four LoVI component laws had consistent, negative associations with partner violence for girls and women, but negative associations were stronger for women than girls. Thus, while laws promoting gender equity and freedom from violence are generally protective, they may be more so for women than adolescent girls. Future research should explore the impact of gender equitable laws on women's and adolescent girls' experiences of violence, and countries may consider more comprehensive legal protections against violence for adolescent girls.

Impact evaluation of the Care Tipping Point Initiative in Nepal: study protocol for a mixed-methods cluster randomised controlled trial.

INTRODUCTION: Girl child, early and forced marriage (CEFM) persists in South Asia, with long-term consequences for girls. CARE's Tipping Point Initiative (TPI) addresses the causes of CEFM by challenging repressive gender norms and inequalities. The TPI engages different participant groups on programmatic topics and supports community dialogue to build girls' agency, shift inequitable power relations, and change community norms sustaining CEFM. METHODS/ANALYSIS: The Nepal TPI impact evaluation has an integrated, mixed-methods design. The quantitative evaluation is a three-arm, cluster randomised controlled trial (control; Tipping Point Programme (TPP); TPP+ with emphasised social norms change). Fifty-four clusters of ~200 households were selected from two districts (27:27) with probability proportional to size and randomised. A household census ascertained eligible study participants, including unmarried girls and boys 12-16 years (1242:1242) and women and men 25+ years (270:270). Baseline participation was 1134 girls, 1154 boys, 270 women and 270 men. Questionnaires covered agency; social networks/norms; and discrimination/violence. Thirty in-depth interviews, 8 key-informant interviews and 32 focus group discussions were held across eight TPP/TPP+ clusters. Guides covered gender roles/aspirations; marriage decisions; girls' safety/mobility; collective action; perceived shifts in child marriage; and norms about girls. Monitoring involves qualitative interviews, focus groups and session/event observations over two visits. Qualitative analyses follow a modified grounded theory approach. Quantitative analyses apply intention to treat, regression-based difference-in-difference strategies to assess impacts on primary (married, marriage hazard) and secondary outcomes, targeted endline tracing and regression-based methods to address potential selection bias. ETHICS/DISSEMINATION: The Nepal Social Welfare Council approved CARE Nepal to operate in the study districts. Emory (IRB00109419) and the Nepal Health Research Council (161-2019) approved the study. We follow UNICEF and CARE guidelines for ethical research involving children and gender-based violence. Study materials are here or available on request. We will share findings through clinicaltrials.gov, CARE reports/briefs and publications. TRIAL REGISTRATION NUMBER: NCT04015856.

Women's experiences of economic coercion and depressive symptoms in Matlab, Bangladesh.

Prior studies of the association between intimate partner violence (IPV) and depressive symptoms have typically excluded economic coercion (EC), a prevalent form of IPV worldwide. Here, we used structural equation models (SEM) to estimate the association of EC with depressive symptoms, with and without adjustment for physical/psychological/sexual IPV, among women in rural Matlab, Bangladesh. Data were collected from cross-sectional surveys with married women 15-49 years, conducted between November 2018 and January 2019. Prior-week depressive symptoms were measured using the 10-item Centre for Epidemiologic Studies Depression short-form. Lifetime EC was assessed using a bi-dimensional, 36-item scale developed in Matlab. Lifetime physical/sexual/psychological IPV was assessed using the 20-item WHO Domestic Violence module. Covariates were age, age at marriage, and schooling; partner's schooling; and household wealth. Among 929 women, lifetime experience of EC ranged from 41.9% (control over access to work, schooling, and training) to 50.0% (control over use/maintenance of economic resources), while any lifetime physical/psychological/sexual IPV was 89.5%. Coercion involving the use and maintenance of economic resources had a significant, adjusted association with depressive symptoms (standardized coefficient = 0.491, p<0.001, R2=0.221). The standardized association of any physical/psychological/sexual IPV with depressive symptoms, adjusted for covariates and cluster sampling, was 0.346 (p <0.001, R2=0.143). When further adjusted for the two measures of EC, the association was attenuated and non-significant (0.049, p = 0.817). These findings suggest that EC is prevalent, significantly associated with depressive symptoms, and attenuates the association of other forms of IPV with depressive symptoms. Addressing EC with other forms of IPV may be necessary to reduce depressive symptoms in exposed women.
