This project aims to test the scalability and cost-effectiveness of edutainment-soap operas designed to challenge harmful social norms and promote resilience-as a strategy to improve mental health and reduce intimate partner violence (IPV) in rural Bangladesh. Investigators will run a clustered randomized control trial in which villages will be randomized to one of three versions of the same soap opera: (i) Norms: Challenges harmful norms that condone IPV, targeting the belief that violence is an acceptable way to assert control or maintain reputation, (ii) Norms + Skills: builds on the norms campaign by adding CBT-based skills for stress management and non-violent conflict resolution, (iii) Placebo: No violence content. Investigators will evaluate the impact on attitudes towards IPV and IPV incidence.
Study design features two layers of commuity-level randomization based on a 3x2 factorial design:
First Treatment Variation: Edutainment Content. Communities are randomized into one of three versions of the same soap opera:
This variation allows for assessing the impact of addressing harmful norms alone from the additional benefits of equipping men with practical coping skills. By comparing the Norms Campaign to the Norms + Skills Campaign, investigators test whether adding stress-coping skills yields additional reductions in IPV and related outcomes.
Second Treatment Variation: Delivery Modes. Fifty percent of communities in each treatment arm are randomized into one of two delivery modes:
Randomizing delivery modes enables investigators to assess whether men's responses to the intervention are driven by self-esteem concerns (private delivery) or reputation concerns (public delivery). This distinction provides critical insights into the mechanisms underlying IPV and informs the scalability of different delivery methods.
In addition to the community-level randomizations, 50 percent of men in each community are randomized into participation in a cash-for-work program. This individual-level randomization allows us to evaluate the role of economic strain in IPV outcomes, testing whether alleviating financial stress enhances the intervention's effectiveness.

| Demographic and Health Survey (DHS) to assess Acceptability of IPV | Standardized attitudinal questions from the Demographic and Health Survey (DHS), which capture whether violence is considered justified in specific situations to measure changes in husbands' personal attitudes towards IPV. Measured by the average score on a justification index across treatments. This index is a normalized index of how justified men think it is for a husband to use IPV. | 1 month post intervention |
| Hypothetical vignettes to assess Acceptability of IPV | Hypothetical vignettes, where respondents evaluate the likely and socially acceptable behavior of a hypothetical husband whose wife transgressed a gender norm. These vignettes mitigate social desirability bias and improve the accuracy of responses on sensitive topics to measure changes in husbands' personal attitudes towards IPV. Measured by the average level of violence respondents across treatments believe hypothetical husband will and should assign if the hypothetical wife transgresses. The scale will be between 0 and 5. | 1 month post intervention |
| Hypothetical vignettes to assess Perceptions about others' acceptability of IPV. | Husbands' perceptions about others' attitudes towards IPV were measured using the hypothetical vignettes. Respondents estimate the attitudes of the other surveyed men in their community using visual aids and stickers, each representing a different respondent. Hypothetical vignettes, where respondents evaluate the likely and socially acceptable behavior of a hypothetical husband whose wife transgressed a gender norm. These vignettes mitigate social desirability bias and improve the accuracy of responses on sensitive topics to measure changes in husbands' personal attitudes towards IPV. This will be measured by the average level of violence respondents across treatments believe other men in their community will assign if the hypothetical wife transgresses. The scale will be between 0 and 5. | 1 month post intervention |

|---|---|---|
| Respectable man scale to assess Men's self-esteem. | Husbands' reports of the likelihood that they are a "respectable man". Investigators constructed the respectable man scale using a combination of qualitative and quantitative methods. Husbands answer ten embedded questions throughout the survey that contribute to their respectable man score. At the end of the interview, investigators inform men that the top five scorers in the community are considered "respectable men," but we do not reveal their actual scores to them. Husbands indicate how confident they are that they rank among the top five in their community. Measured by the mean likelihood that men across treatments think they rank among the top five respectable men in their community. The scale will be between 0 and 100. |

Treatment assignment was stratified at the union level, the smallest administrative rural unit. From the two districts combined, a total of 88 unions were selected using Probability Proportional to Size (PPS). Each union contained 5 clusters (villages), yielding a total of 440 clusters. In each village, investigators randomly sampled 20 married couples aged 18-65, yielding a total of 8,800 married couples.

Men's coping and emotional self-regulation strategies are measured using an index constructed from responses provided by their wives. This index includes selected questions on men's approaches to conflict management from the Revised Conflict Tactics Scale, adapted items from the Bengali version of the Brief Resilient Coping Scale that capture spouses' perceptions of men's behavior, and measures of substance use. IPV-related questions are intentionally excluded, as these behaviors represent a distinct conceptual category measured separately. To simplify interpretation, the index is standardized relative to the control group by subtracting the control group's mean and dividing by its standard deviation. Consequently, the resulting index has a mean of zero and a standard deviation of one within the control group. Higher values of the index indicate more positive coping styles and better emotional regulation. |

| Patient Health Questionnaire-9 (PHQ-9) to assess Men's resilience and mental health. | Husbands' self-reported symptoms of depression measured using the PHQ-9 scale. PHQ-9 is a 9-item validated questionnaire used to screen for depression with a range of scores from 0-45. A cumulative score of ≥10 is considered positive with lower scores indicating no or mild anxiety. | 1 month post intervention |
| Stressors and experiences to assess Men's resilience and mental health. | Husbands' open-ended responses on daily stressors and positive experiences to measure husbands' resilience and emotional well-being. A summary index with two subcomponents is developed. First, a sub-index of daily events using an adapted version of the Daily Hassles and Uplifts Scale that includes items relevant to our target population. Second, a sub-index that aggregates men's appraisal of stressors and is based on the 10-item version of the Perceived Stress Scale validated in Bangladesh. Each subcomponent is standardized to have a mean of zero and a standard deviation of one for the control group. The summary index is defined as the equally weighted average of these standardized sub-indexes, with signs oriented so that higher values consistently indicate more favorable outcomes (fewer stressors and/or lower perceived stress). | 1 month post intervention |
| Biometric stress indicators to assess Men's resilience and mental health. | Biometric stress indicators, captured by Empatica E4 wristbands during sensitive survey modules, measuring physiological markers of emotional regulation and stress to measure husbands' resilience and emotional well-being. Specifically, electrodermal activity (EDA) data, expressed in microsiemens (μS), is used to analyze Skin Conductance Responses (SCRs). SCRs are quantified using a trough-to-peak (TTP) analysis, where the amplitude of each response is measured as the difference between the peak and the preceding trough within a defined time window. To identify event-related SCRs, a response window of 1 to 5 seconds following a stimulus is applied, with a minimum amplitude threshold of 0.01 μS to detect significant responses. The primary outcome variable is the sum of SCR amplitudes for significant responses. The average sum of SCR amplitudes across treatment groups is compared to assess differences in physiological stress responses. | 1 month post intervention |
| Adapted version of the DHS to assess Prevalence and frequency of IPV. | An adapted version of the DHS, covering physical, psychological, financial, and sexual violence. To enhance privacy and reduce misreporting, women use visual response tools to answer these questions privately to measure women's experiences of IPV. Measured by the average of a standardized IPV index. This is a normalized index which captures the frequency (never, very few times, sometimes, or very often) of women's reported experiences of IPV in the past six months. Higher values indicate higher frequency of IPV. | 1 month post intervention |
| Number of participants with IPV-related injuries to assess Prevalence and frequency of IPV. | Enumerators' reports of visible IPV-related injuries, such as bruises, documented using a standardized reporting protocol. Enumerators receive specialized training to identify and record signs of physical violence, with a focus on facial bruises and scratches, which remain visible even for veiled women to measure women's experiences of IPV. | 1 month post intervention |
| Health assessments to assess Prevalence and frequency of IPV. | Health assessments by community health workers, who check for IPV-related injuries to measure women's experiences of IPV. Measured by the percentage of female respondents across treatments on whom community health workers identify IPV-related injuries. | 1 month post intervention |
| Incidence of IPV to assess Prevalence and frequency of IPV. | Women's self-reports of IPV through rolling phone surveys six to twelve months post-intervention. Measured by the average of a standardized IPV index. This is a normalized index which captures the frequency (never, very few times, sometimes, or very often) of women's reported experiences of IPV in the past six months. | Baseline and 6-12 months post intervention |
| 1 month post intervention |
| Perceived respectabillity to assess Men's reputation | Husbands' perceived probability that two randomly selected community members would consider them respectable, elicited using an identical ten-bean method. To reduce misreporting, husbands receive financial incentives based on the accuracy of their estimates. Measured by the mean likelihood that men across treatments think others rank them among the top five respectable men in their community. The scale will be between 0 and 100. | 1 month post intervention |
| Cost-effectiveness of the edutainment campaigns assessed by Reduction to IPV exposure | Reduction in the number of women exposed to IPV or the intensity of IPV in the last six months per USD 1,000. Multiply the observed reduction in IPV (either in absolute prevalence or an intensity index) caused by each edutainment campaign by the total number of men assigned to that campaign. Investigators will calculate costs by summing both start-up and implementation costs. Start-up costs include intervention development (content production and pilot testing), adaptation (translation and cultural adjustments), and set-up (community engagement and facilitator training). Implementation costs include broadcasting and screening expenses, facilitator compensation, and routine monitoring and evaluation. Research-related expenditures will be excluded and only include costs related to activities expected at scale. | 1 month post intervention |
| Cost-effectiveness of the edutainment campaigns assessed by benefit-to-cost ratio | Benefit-to-cost ratio calculated by dividing the estimated benefits from reduced IPV by the total costs of intervention delivery. To estimate the benefits of IPV reduction, investigators will use the treatment effects on income and a web-based cost benefit analysis tool developed by one of the Principal Investigators. This tool calculates the lifetime economic returns to increased income. | 1 month post intervention |
| Cost-effectiveness of the edutainment campaigns assessed by benefit-to-cost ratio | Net present value calculated as the difference in discounted benefits and costs. To estimate the benefits of IPV reduction, investigators will use the treatment effects on income and a web-based cost-benefit analysis tool developed by one of the Principal Investigators. This tool calculates the lifetime economic returns to increased income. The unit of measure for NPV is 1000 USD. | 1 month post intervention |
