Measuring the cost-effectiveness of a home-visiting intervention to promote early child development among rural families linked to the Rwandan social protection system.

Early childhood development (ECD) programmes are heralded as a way to improve children's health and educational outcomes. However, few studies in developing countries calculate the effectiveness of quality early childhood interventions. This study estimates the cost and cost-effectiveness of the Sugira Muryango (SM) trial, a home-visiting intervention to improve ECD outcomes through positive parent-child relationships. Cost-effectiveness analysis of ECD interventions is challenging given their potential to have multiple benefits. We propose a cost-effectiveness method using a single outcome, in this case the improvement in cognitive development per home-visit session, as an indication of efficiency comparable across similar interventions. The trial intervention cost US$456 per family. This cost will likely fall below US$200 if the intervention is scaled through government systems. The cost-effectiveness analysis suggests that while SM generated a relatively small impact on markers of early development, it did so efficiently. The observed improvements in cognitive development per home-visit are similar to other home-visiting interventions of longer duration. SM by focusing on the family had benefits beyond ECD, including reductions in violence against children and intermate partner violence, further analysis is needed to include these returns in the economic evaluation.

Family Violence Reduction Within a Parenting Intervention in Rwanda: A Mixed-Methods Study.

BACKGROUND AND OBJECTIVES: A mixed-methods study of mechanisms of change through which a home-visiting-based early childhood development intervention, Sugira Muryango ("strong family"), reduced violent discipline and intimate partner violence in Rwanda. METHODS: The cluster-randomized trial of Sugira Muryango enrolled socioeconomically vulnerable families with children aged 6 to 36 months in rural Rwanda. We interviewed 18 female caregivers early in the intervention, and 21 female caregivers and 11 male intimate partners were interviewed after the intervention. Coded interviews identify risk factors for violence and mechanisms of intervention-related change in violence. Quantitative analyses included 931 caregivers (52.6% female) who lived with an intimate partner to examine risk factors for violence, intervention effects, and mechanisms of violence reduction. RESULTS: The qualitative data identified daily hardships and alcohol problems as risk factors for violent discipline and intimate partner violence. Through Sugira Muryango, caregivers learned that strong relationships between partners and engagement of male caregivers in child care has positive impacts on children's development. Techniques taught by community lay workers improved communication, promoted positive parent-child interactions, and reduced intimate partner violence and violent discipline. Quantitative analyses also found that daily hardships predict violent discipline and intimate partner violence. Sugira Muryango reduced violent discipline, increased father engagement, and increased female caregiving warmth. Moreover, pre- to postintervention change in caregiving warmth was associated with reduced use of violent discipline among female caregivers and marginally associated with reduced female victimization. CONCLUSIONS: Violence reduction can be integrated into early child development programs to reduce violent discipline and intimate partner violence.

Effect of a home-visiting parenting program to promote early childhood development and prevent violence: a cluster-randomized trial in Rwanda.

INTRODUCTION: Families living in extreme poverty require interventions to support early-childhood development (ECD) due to broad risks. This longitudinal cluster randomised trial examines the effectiveness of Sugira Muryango (SM), a home-visiting intervention linked to Rwanda's social protection system to promote ECD and reduce violence compared with usual care (UC). METHODS: Families with children aged 6-36 months were recruited in 284 geographical clusters across three districts. Cluster-level randomisation (allocated 1:1 SM:UC) was used to prevent diffusion. SM was hypothesised to improve child development, reduce violence and increase father engagement. Developmental outcomes were assessed using the Ages and Stages Questionnaire (ASQ-3) and the Malawi Development Assessment Tool (MDAT) and anthropometric assessments of growth. Violence was assessed using questions from UNICEF Multiple Indicators Cluster Survey (MICS) and Rwanda Demographic and Health Surveys (DHS). Father engagement was assessed using the Home Observation for Measurement of the Environment. Blinded enumerators conducted interviews and developmental assessments. RESULTS: A total of 541 SM families and 508 UC families were enrolled and included in the analyses. Study attrition (2.0% children; 9.6% caregivers) was addressed by hot deck imputation. Children in SM families improved more on gross motor (d=0.162, 95% CI 0.065 to 0.260), communication (d=0.081, 95% CI 0.005 to 0.156), problem solving (d=0.101, 95% CI 0.002 to 0.179) and personal-social development (d=0.096, 95% CI -0.015 to 0.177) on the ASQ-3. SM families showed increased father engagement (OR=1.592, 95% CI 1.069 to 2.368), decreased harsh discipline (incidence rate ratio, IRR=0.741, 95% CI 0.657 to 0.835) and intimate partner violence (IRR=0.616, 95% CI:0.458 to 0.828). There were no intervention-related improvements on MDAT or child growth. CONCLUSION: Social protection programmes provide a means to deliver ECD intervention. TRIAL REGISTRATION NUMBER: NCT02510313.

Intergenerational impacts of trauma and hardship through parenting.

BACKGROUND: Millions of people worldwide experience severe trauma in their lifetime. Trauma has immediate and long-term effects on emotional wellbeing. Moreover, the experiences of one generation may influence subsequent generations via social and biological pathways. Poor mental health and emotion dysregulation associated with trauma may affect parenting behaviours, which may have long-lasting effects on children's development. METHODS: We use longitudinal data from a unique sample of 732 caregivers of children aged 6-36 months living in extremely poor rural households in Rwanda to examine associations of caregiver lifetime trauma, recent daily hardships, mental health, and emotion dysregulation with parenting behaviours reflecting parental acceptance and rejection of their offspring. RESULTS: Cumulative trauma exposure (ß = .234, p < .001) and recent daily hardships (ß = .323, p < .001) are associated with higher levels of internalising symptoms. Trauma (ß = .257, p < .001) and daily hardships (ß = .323, p < 0.001) are also associated with post-traumatic stress disorder (PTSD) symptoms. Internalising symptoms predict more rejection (ß = .177, p = .001), but show no association with acceptance. Caregiver PTSD symptoms predict more rejection (ß = .277, p < .001) and less acceptance (ß = -.190, p = .003). Both internalising symptoms (ß = .557, p < .001) and PTSD symptoms (ß = .606, p < .001) are strongly associated with poor emotion regulation. Indirect effects suggest that caregiver trauma and hardships affect parenting indirectly via elevated caregiver internalising symptoms and PTSD and that some of these effects are accounted for by emotion dysregulation. CONCLUSIONS: Caregiver internalising and PTSD symptoms are important mechanisms through which caregiver trauma and hardship affect parenting behaviours. Emotion dysregulation is a shared mechanism linking caregivers' mental health problems with parenting behaviours that reflect acceptance and rejection of the child. Emotion regulation is indicated as a key target for prevention of adverse effects of caregiver trauma on mental health and child wellbeing.

Promoting parent-child relationships and preventing violence via home-visiting: a pre-post cluster randomised trial among Rwandan families linked to social protection programmes.

BACKGROUND: Sugira Muryango is a father-engaged early child development and violence-prevention home-visiting programme delivered by trained lay workers. This cluster-randomised trial evaluates whether families living in extreme poverty (Ubudehe 1, the poorest category in the Government of Rwanda's wealth ranking) who receive Sugira Muryango in combination with a government-provided social protection programme demonstrate greater responsive, positive caregiving, nutrition, care seeking, hygiene, and father involvement compared with control families receiving usual care (UC). METHODS: Using detailed maps, we grouped closely spaced villages into 284 geographic clusters stratified by the type of social protection programmes operating in the village clusters; 198 clusters met all enrolment criteria. Sugira Muryango was delivered to n = 541 families in 100 treatment clusters with children aged 6-36 months living in extreme poverty. We assessed changes in outcomes in intervention and n = 508 UC control families using structured surveys and observation. Analyses were intent to treat using mixed models to accommodate clustering. RESULTS: Families receiving Sugira Muryango improved on core outcomes of parent-child relationships assessed using the Home Observation for Measurement of the Environment (Cohen's d = 0.87, 95% CI: 0.74, 0.99) and the Observation of Mother-Child Interaction (Cohen's d = 0.29, 95% CI: 0.17, 0.41). We also saw reductions in harsh discipline on items from the UNICEF MICS (OR = 0.30: 95% CI: 0.19, 0.47) and in violent victimisation of female caregivers by their partners (OR = 0.49, 95% CI: 0.24, 1.00) compared with UC. Moreover, children in families receiving SM had a 0.45 higher increase in food groups consumed in the past 24 h (Cohen's d = 0.35, 95% CI: 0.22, 0.47), increased care seeking for diarrhoea (OR = 4.43, 95% CI: 1.95, 10.10) and fever (OR = 3.28, 95% CI: 1.82, 5.89), and improved hygiene behaviours such as proper treatment of water (OR = 3.39, 95% CI: 2.16, 5.30) compared with UC. Finally, Sugira Muryango was associated with decreased caregiver depression and anxiety (OR = 0.58, 95% CI: 0.38, 0.88). CONCLUSIONS: Sugira Muryango led to improvements in caregiver behaviours linked to child development and health as well as reductions in violence.
