Strategies to Prevent Violence Against Children in the Home: A Systematic Review of Reviews.

Violence against children (VAC) in the home, or by household members, is a human rights and social problem with long-lasting consequences for individuals and society. Global policy instruments like the INSPIRE package have proposed strategies to prevent VAC, including Implementation and enforcement of laws, Norms and values, Safe environments, Parent and caregiver support, Income and economic strengthening, Response and support services, and Education and life skills. This systematic review of reviews aimed to synthesize the recent evidence base (i.e., published since 2000) for each INSPIRE strategy to reduce VAC in the home or by household members. We searched four databases using controlled vocabularies and keywords and searched for additional records in prior reviews of reviews. A total of 67 studies were included in this review, including literature reviews, meta-analyses, systematic reviews, and other types of reviews. We found extensive evidence supporting the effectiveness of parent and caregiver support interventions. However, reviews on other INSPIRE strategies were scarce. We also found a vast underrepresentation of samples from low- and- middle-income countries, children with disabilities, and families affected by forced displacement and conflict. In sum, this systematic review suggests that there are several promising strategies to prevent VAC (e.g., home visiting and parent education), but further research is necessary to strengthen the current body of evidence and effectively inform the implementation and scale-up of evidence-based interventions to protect children from violence globally.

Principles for Adapting Assessments of Executive Function across Cultural Contexts.

Direct assessments of executive functions (EFs) are increasingly used in research and clinical settings, with a central assumption that they assess "universal" underlying skills. Their use is spreading globally, raising questions about the cultural appropriateness of assessments devised in Western industrialized countries. We selectively reviewed multidisciplinary evidence and theory to identify sets of cultural preferences that may be at odds with the implicit assumptions of EF assessments. These preferences relate to motivation and compliance; cultural expectations for interpersonal engagement; contextualized vs. academic thinking; cultural notions of speed and time; the willingness to be silly, be incorrect, or do the opposite; and subject-matter familiarity. In each case, we discuss how the cultural preference may be incompatible with the assumptions of assessments, and how future research and practice can address the issue. Many of the cultural preferences discussed differ between interdependent and independent cultures and between schooled and unschooled populations. Adapting testing protocols to these cultural preferences in different contexts will be important for expanding our scientific understanding of EF from the narrow slice of the human population that has participated in the research to date.

Association of Neighborhood Opportunity with Infant Brain Activity and Cognitive Development.

BACKGROUND AND OBJECTIVES: Neighborhood socioeconomic disadvantage is associated with lower neurocognitive scores and differences in brain structure among school-age children. Associations between positive neighborhood characteristics, infant brain activity, and cognitive development are underexplored. We examined direct and indirect associations between neighborhood opportunity, brain activity, and cognitive development. METHODS: This longitudinal cohort study included infants from 2 primary care clinics in Boston and Los Angeles. Using a sample of 65 infants, we estimated path models to examine associations between neighborhood opportunity (measured by the Child Opportunity Index), infant electroencephalography (EEG) at 6 months, and infant cognitive development (measured using the Mullen Scales of Early Learning) at 12 months. A mediation model tested whether EEG power explained associations between neighborhood opportunity and infant cognition. RESULTS: Neighborhood opportunity positively predicted infant absolute EEG power across multiple frequency bands: low (b = 0.12, 95% CI 0.01-0.24, p = 0.04, = 0.21); high (b = 0.11, 95% CI 0.01-0.21, p = 0.03, = 0.23); (b = 0.10, 95% CI 0.00-0.19, p = 0.04, = 0.20); and (b = 0.12, 95% CI 0.02-0.22, p = 0.02, = 0.24). The results remained statistically significant after applying a Benjamini-Hochberg false discovery rate of 0.10 to adjust for multiple comparisons. No significant associations emerged between neighborhood opportunity, relative EEG power, and infant cognition. Mediation was not significant. CONCLUSION: Neighborhood opportunity is positively associated with some forms of infant brain activity, suggesting that positive neighborhood characteristics may play a salient role in early development.

A Qualitative Study of Maternal Perceptions of Stress and Parenting During Early Childhood.

OBJECTIVE: Exposure to maternal stress in early childhood can increase risk for learning and behavior challenges. We sought to gain in-depth understanding of how mothers perceive stressors to impact child wellbeing and identify mothers' strategies for navigating stressors with their young children. METHODS: We recruited English- and Spanish-speaking mothers from a primary care clinic serving predominantly publicly insured children. Twenty-one mothers (aged >18 years) of children (aged 6-29 months) participated in in-depth, semi-structured interviews to discuss their experiences and beliefs regarding stress and parenting. Interviews were recorded, transcribed verbatim, and analyzed using the constant comparative method associated with a grounded theory approach. RESULTS: We developed the following hypothesized explanatory model based on our key thematic findings: Mothers described a dyadic model of stress, whereby both their children's and their own experiences of and responses to stressors are interdependent. Mothers use preventive and responsive buffering to mitigate the impact of stress on their children; however, their access to resources, including social and financial support, shapes their capacity for implementing such strategies. Affection and other forms of relational support may function to protect against the negative impacts of stress. CONCLUSION: In the setting of poverty-related chronic stressors, mothers play an active role in mitigating the impact of stress on their children's wellbeing through responsive caregiving. Policies aimed at reducing poverty-related stress exposures and experiences among low-income families may be key interventions for promoting responsive caregiving during a critical time in child development.

The acute effects of community violence on young children's regulatory, behavioral, and developmental outcomes in a low-income urban sample in Brazil.

BACKGROUND: Existing research on the impacts of adversity on young children's psychological well-being has largely focused on household-level risk factors using observational methods in high-income countries. This study leverages natural variation in the timing and location of community homicides to estimate their acute effects on the regulatory, behavioral, and developmental outcomes of Brazilian 3-year-olds. METHODS: We compared the outcomes of children who were assessed soon after a recent neighborhood homicide to those of children from the same residential neighborhoods who had not recently experienced community violence. Our sample included 3,241 3-year-olds (Mage = 41.05 months; 53% female; 45% caregiver education less than middle school; 26% receiving a public assistance program) from seven neighborhoods in São Paulo, Brazil. Child outcome measures included parent reports of effortful control and behavior problems as well as direct assessments of children's developmental (cognitive, language, and motor) skills. Community homicides were measured using police records. RESULTS: Recent exposure to community homicides was associated with lower effortful control, higher behavior problems, and lower overall developmental performance for children (d = .05-.20 standard deviations; p = ns - <.001). Effects were consistent across subgroups based on sociodemographic characteristics and environmental supports, but generally largest when community violence exposure was geographically proximal (within 600 m of home) and recent (within 2 weeks prior to assessment). CONCLUSIONS: Results highlight the pervasive effects that community violence can have on young children as well as the need to expand support to mitigate these effects and prevent inequities early in life.

Country-Level Improvements in Nurturing Care and Child Development.

This cross-sectional study examines whether provision of nurturing care in 31 countries over 10 years was associated with improvements in countries' child development outcomes.

Psychometrics of psychosocial behavior items under age 6 years: Evidence from Nebraska, USA.

Because healthy psychosocial development in the first years of life is critical to lifelong well-being, governmental, and nongovernmental organizations are increasingly interested in monitoring psychosocial behaviors among populations of children. In response, the World Health Organization is developing the Global Scales of Early Development Psychosocial Form (GSED PF) to facilitate population-level psychosocial monitoring. Once validated, the GSED PF will be an open-access, caregiver-reported measure of children's psychosocial behaviors that is appropriate for infants and young children. This study examines the psychometric validity evidence from 45 items under consideration for inclusion in the GSED PF. Using data from N = 836 Nebraskan (USA) children aged 180 days to 71 months, results indicate that scores from 44 of the 45 (98%) items exhibit positive evidence of validity and reliability. A bifactor model with one general factor and five specific factors best fit the data, exhibited strong reliability, and acceptable model fit. Criterion associations with known predictors of children's psychosocial behaviors were in the expected direction. These findings suggest that measurement of children's psychosocial behaviors may be feasible, at least in the United States. Data from more culturally and linguistically diverse settings is needed to assess these items for global monitoring.

Debido a que el desarrollo sicosocial en los primeros años de vida es crítico para el bienestar de toda la vida, las organizaciones gubernamentales y no gubernamentales están más y más interesadas en observar vigilantemente las conductas sicosociales en la población infantil. Como respuesta, la Organización Mundial de la Salud está desarrollando el Formulario Sicosocial de las Escalas Globales del Temprano Desarrollo (GSED PF) para facilitar la observación sicosocial alerta al nivel del grupo de población. Una vez que se haya convalidado, el GSED PF será una medida de acceso abierto, que reportará el cuidador, sobre las conductas sicosociales de los niños que son apropiadas para infantes y niños pequeñitos. Este estudio examina la evidencia de la validez sicométrica de 45 puntos bajo consideración para ser incluidos en el GSED PF. Usando datos de N = 836 niños de Nebraska (Estados Unidos), de edad entre 180 días y 71 meses, los resultados indican que los puntajes de 44 de los 45 (98%) puntos muestran evidencia positiva de validez y confiabilidad. Un modelo bifactorial con un factor general y cinco factores específicos, que mejor encaja con los datos, mostró una fuerte confiabilidad y un modelo aceptable que encaja. Las asociaciones de criterio con factores de predicción conocidos acerca de las conductas sicosociales de los niños se encontraban en la dirección esperada. Estos resultados sugieren que la medida de las conductas sicosociales de los niños pudiera ser posible, por lo menos en los Estados Unidos. Se necesitan datos de escenarios más diversos cultural y lingüísticamente para evaluar estos puntos para la estar alerta en la observación global.

Digital Support Systems to Improve Child Health and Development in Peru: Protocol for a Randomized Controlled Trial.

BACKGROUND: Children living in low and middle-income countries (LMICs) are at greater risk for experiencing adversities that can undermine their health and early development. Recently launched digital early childhood development (ECD) programs attempt to support families with young children in their home environments using digital technologies. However, relatively little is known regarding the effectiveness of these new technologies. OBJECTIVE: The goal of this study is to rigorously assess the reach, effectiveness, and cost-effectiveness of a newly developed digital ECD platform called Afini. The Afini platform was designed to support parents of young children in low-resource settings to improve ECD and interact with caregivers through messenger services and a chatbot. METHODS: This is a 3-arm cluster randomized controlled trial. In total, 2471 caregivers and their 3- to 9-month-old children were enrolled in the study across 164 study clusters in the San Marcos, Cajabamba, and Cajamarca provinces of Peru. Clusters of participants were randomly assigned to 1 of 3 groups: a control group (72 community clusters and 980 caregiver-child dyads), a home visit intervention group (20 community clusters and 316 caregiver-child dyads), and an Afini intervention group (72 community clusters and 1175 caregiver-child dyads). Families in the control group receive no focused ECD intervention. The home visit group is receiving biweekly home visits by a trained field staff following the national ECD program (Programa Nacional Cuna Más) curriculum and training guidelines. Caregivers in the Afini group are receiving ECD activities and advice through the digital platform. The primary study outcome is children's overall development at the age of 2.5 years, using the internationally validated long form of the Global Scales for Early Development. Secondary outcomes include caregiver engagement; caregiver mental health; screen time; as well as caregiver reports of children's motor, cognitive, language, and socioemotional development measured through locally piloted and validated tools. RESULTS: Enrollment started in September 2021 and ended in March 2023. Endline assessments will take place between August 2023 and September 2024. CONCLUSIONS: This study is, to our knowledge, the first to rigorously assess the effectiveness and cost-effectiveness of digital ECD technologies in LMICs. Given the large number of children in LMICs currently receiving only limited external support, the evaluated platform has the potential to improve the short- and long-term well-being of millions of children and their parents globally.

Impacts of the Chicago School Readiness Project on measures of achievement, cognitive functioning, and behavioral regulation in late adolescence.

The current paper reports long-term impacts of the Chicago School Readiness Project (CSRP) on measures of achievement, cognitive functioning, and behavioral regulation taken toward the end of students' high school careers. The CSRP was a self-regulation-focused early childhood intervention implemented in Head Start centers serving high-poverty neighborhoods in Chicago. The intervention was evaluated through a cluster randomized control trial, providing us with rare longitudinal evidence from an experimental study. However, the study was limited by issues with low power and baseline differences between experimental groups. Here, we report on follow-up data taken approximately 11-14 years after program completion, including measures of participants' (N = 430) academic achievement, executive functioning, emotional regulation, and behavioral problems, and we provide a range of analytic estimates to address the study's methodological concerns. Across our estimates, we found little evidence that the program had lasting impacts on indicators of late-adolescent functioning. Main effects were estimated with some imprecision, but nearly all models produced null effects across the broad array of outcomes considered. We also observed few indications that effects were moderated by posttreatment high school quality or later assignment to a light-touch mindset intervention. Implications for developmental theory and early childhood policy are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Global tracking of access and quality in early childhood care and education.

Investments in early childhood care and education (ECCE) have contributed to a growing demand for internationally comparable data. Yet data on access to quality ECCE are not routinely collected in many countries, leading to limited information on equitable access to ECCE, quality of provision, and the impact on learning and wellbeing outcomes. This paper outlines the current status of global measurement of access to quality ECCE and identifies issues with definitions, availability, and accuracy of ECCE data across countries and outlines paths forward. We argue that estimates of access to ECCE should be based on children's participation in quality ECCE across multiple program types, rather than enrollment or attendance alone, given the critical importance of dosage and participation for ensuring positive benefits from ECCE. Governments, international organizations, and researchers all have roles to play in setting standards to define and monitor ECCE, generating workable tools for measuring nationally, and globally investing in national monitoring systems and routine household surveys to obtain accurate estimates of access to quality ECCE.

Family play, reading, and other stimulation and early childhood development in five low-and-middle-income countries.

This paper used longitudinal data from five studies conducted in Bangladesh, Bhutan, Cambodia, Ethiopia, and Rwanda to examine the links between family stimulation and early childhood development outcomes (N = 4904; Mage = 51.5; 49% girls). Results from random-effects and more conservative child-fixed effects models indicate that across these studies, family stimulation, measured by caregivers' engagement in nine activities (e.g., reading, playing, singing), predicted increments in children's early numeracy, literacy, social-emotional, motor, and executive function skills (standardized associations ranged from 0.05 to 0.11 SD). Study-specific models showed variability in the estimates, with null associations in two out of the five studies. These findings indicate the need for additional research on culturally specific ways in which caregivers may support early development and highlight the importance of promoting family stimulation to catalyze positive developmental trajectories in global contexts. RESEARCH HIGHLIGHTS: Research on the links between family stimulation and early childhood development in low-and-middle-income countries (LMICs) is limited. We used longitudinal data from studies conducted in five LMICs to examine the links between family stimulation and early childhood development outcomes. Results suggest that family stimulation predicted increments in children's numeracy, literacy, social-emotional, motor, and executive function skills. We found variability in the observed estimates, with null associations in two out of the five studies, suggesting the need for additional research in LMICs.

Digital tools to improve parenting behaviour in low-income settings: a mixed-methods feasibility study.

INTRODUCTION: Digital parenting interventions could be potentially cost-effective means for providing early child development services in low-income settings. This 5-month mixed-methods pilot study evaluated the feasibility of using Afinidata, a comprehensive Facebook Messenger-based digital parenting intervention in a remote rural setting in Latin America and explored necessary adaptations to local context. METHODS: The study was conducted in three provinces in the Cajamarca region, Peru, from February to July 2021. 180 mothers with children aged between 2 and 24 months and regular access to a smartphone were enrolled. Mothers were interviewed three times in-person. Selected mothers also participated in focus groups or in-depth qualitative interviews. RESULTS: Despite the rural and remote study site, 88% of local families with children between 0 and 24 months had access to internet and smartphones. Two months after baseline, 84% of mothers reported using the platform at least once, and of those, 87% rated it as useful to very useful. After 5 months, 42% of mothers were still active on the platform, with little variation between urban and rural settings. Modifications to the intervention focused on assisting mothers in navigating the platform independently and included adding a laminated booklet with general information on child development, sample activities and detailed instructions on how to self-enrol in case of lost phones. CONCLUSIONS: We found high access to smartphones and the intervention was well received and used in very remote areas of Peru, suggesting that digital parenting interventions could be a promising path forward for supporting low-income families in remote parts of Latin America.

Systemic barriers and opportunities for implementing school-based social-emotional learning interventions in low-income and conflict-affected settings.

Children living in low-income and conflict-affected settings face unique systemic risk factors that shape their social, emotional, and mental well-being. However, little is known about how these and other systemic factors may impede or support the delivery of social-emotional learning (SEL) interventions in these contexts. In this article, we draw from our experience delivering and evaluating a classroom-based SEL curriculum in Rio de Janeiro, Brazil to surface systemic barriers and opportunities for implementing SEL interventions in low-income, conflict-affected settings. Specifically, we identify (1) culture, (2) timing, and (3) government support and stability as factors underlying SEL program demand, dosage, quality, and effectiveness. We provide recommendations for improving implementation of SEL programs in low-income and conflict-affected contexts, including the importance of building pro-active partnerships, using qualitative research, and investing in adaptation to both understand and address systemic barriers.

The creation of the Global Scales for Early Development (GSED) for children aged 0-3 years: combining subject matter expert judgements with big data.

INTRODUCTION: With the ratification of the Sustainable Development Goals, there is an increased emphasis on early childhood development (ECD) and well-being. The WHO led Global Scales for Early Development (GSED) project aims to provide population and programmatic level measures of ECD for 0-3 years that are valid, reliable and have psychometrically stable performance across geographical, cultural and language contexts. This paper reports on the creation of two measures: (1) the GSED Short Form (GSED-SF)-a caregiver reported measure for population-evaluation-self-administered with no training required and (2) the GSED Long Form (GSED-LF)-a directly administered/observed measure for programmatic evaluation-administered by a trained professional. METHODS: We selected 807 psychometrically best-performing items using a Rasch measurement model from an ECD measurement databank which comprised 66 075 children assessed on 2211 items from 18 ECD measures in 32 countries. From 766 of these items, in-depth subject matter expert judgements were gathered to inform final item selection. Specifically collected were data on (1) conceptual matches between pairs of items originating from different measures, (2) developmental domain(s) measured by each item and (3) perceptions of feasibility of administration of each item in diverse contexts. Prototypes were finalised through a combination of psychometric performance evaluation and expert consensus to optimally identify items. RESULTS: We created the GSED-SF (139 items) and GSED-LF (157 items) for tablet-based and paper-based assessments, with an optimal set of items that fit the Rasch model, met subject matter expert criteria, avoided conceptual overlap, covered multiple domains of child development and were feasible to implement across diverse settings. CONCLUSIONS: State-of-the-art quantitative and qualitative procedures were used to select of theoretically relevant and globally feasible items representing child development for children aged 0-3 years. GSED-SF and GSED-LF will be piloted and validated in children across diverse cultural, demographic, social and language contexts for global use.

Protocol for validation of the Global Scales for Early Development (GSED) for children under 3 years of age in seven countries.

INTRODUCTION: Children's early development is affected by caregiving experiences, with lifelong health and well-being implications. Governments and civil societies need population-based measures to monitor children's early development and ensure that children receive the care needed to thrive. To this end, the WHO developed the Global Scales for Early Development (GSED) to measure children's early development up to 3 years of age. The GSED includes three measures for population and programmatic level measurement: (1) short form (SF) (caregiver report), (2) long form (LF) (direct administration) and (3) psychosocial form (PF) (caregiver report). The primary aim of this protocol is to validate the GSED SF and LF. Secondary aims are to create preliminary reference scores for the GSED SF and LF, validate an adaptive testing algorithm and assess the feasibility and preliminary validity of the GSED PF. METHODS AND ANALYSIS: We will conduct the validation in seven countries (Bangladesh, Brazil, Côte d'Ivoire, Pakistan, The Netherlands, People's Republic of China, United Republic of Tanzania), varying in geography, language, culture and income through a 1-year prospective design, combining cross-sectional and longitudinal methods with 1248 children per site, stratified by age and sex. The GSED generates an innovative common metric (Developmental Score: D-score) using the Rasch model and a Development for Age Z-score (DAZ). We will evaluate six psychometric properties of the GSED SF and LF: concurrent validity, predictive validity at 6 months, convergent and discriminant validity, and test-retest and inter-rater reliability. We will evaluate measurement invariance by comparing differential item functioning and differential test functioning across sites. ETHICS AND DISSEMINATION: This study has received ethical approval from the WHO (protocol GSED validation 004583 20.04.2020) and approval in each site. Study results will be disseminated through webinars and publications from WHO, international organisations, academic journals and conference proceedings.

Implementation characteristics of father-inclusive interventions in low- and middle-income countries: A systematic review.

Although prior reviews have documented the effectiveness of engaging male caregivers in early childhood interventions, little is known about how these interventions have been designed and implemented to reach, engage, and support male caregivers in low-resource global settings. We searched five bibliographic databases for intervention studies that engaged male caregivers to improve nurturing care for children under 5 years of age in low- and middle-income countries. Forty-four articles met the inclusion criteria, which represented 33 interventions. Fathers specifically were the most common type of male caregivers targeted in these interventions. The majority of interventions invited fathers to participate alongside their female partners. Community-based peer-groups were the most common delivery model. Most interventions used the same program structure for fathers as applied to mothers, with few considering whether implementation adaptations were needed for men. Intervention curricula were multicomponent and largely targeted child nutrition, health, and couples' relationships. A minority of programs addressed parenting, psychosocial wellbeing, violence prevention, gender attitudes, or economic support. Behavior change techniques were limited to interactive counseling and peer learning. Male caregivers remain missing from caregiving interventions for young children. A greater focus on implementation research can inform better inclusion, engagement, and support for male caregivers in nurturing care interventions.

Association of Exposure to Intimate Partner Violence With Maternal Depressive Symptoms and Early Childhood Socioemotional Development Among Mothers and Children in Rural Tanzania.

Importance: Approximately 1 in 4 women experience intimate partner violence (IPV) or nonpartner sexual violence during their lifetime. Mothers exposed to IPV are more likely to experience depressive symptoms and to discipline their children harshly, which may affect their children's socioemotional development; however, there is limited evidence on these outcomes. Objective: To examine the association between IPV, maternal depressive symptoms, harsh child discipline, and child stimulation with child socioemotional development. Design, Setting, and Participants: This study used cross-sectional follow-up data collected from February 19 to October 10, 2014, from a birth cohort of children aged 18 to 36 months who were enrolled in a randomized, double-blind, placebo-controlled trial of neonatal vitamin A supplementation in the Morogoro region of Tanzania. Data analysis occurred between September 10, 2019, and January 20, 2020. Exposures: Lifetime experience of IPV was assessed using an abbreviated module of the Tanzania Demographic and Health Survey, maternal depressive symptoms were assessed with the Patient Health Questionnaire, and data on harsh child discipline and maternal stimulation of their children were collected using modules of the United Nations Children's Fund Multiple Indicator Cluster Survey. Main Outcomes and Measures: Child socioemotional development was measured by the Caregiver-Reported Early Childhood Development Instruments. Results: A total of 981 mother-child dyads were included in the analytic sample; 388 children (39.6%) were between ages 18 and 24 (mean [SD] age, 27.06 [6.08]) months, and 515 (52.5%) were male children. A negative association was observed between maternal report of physical IPV only (mean difference, -0.022; 95% CI, -0.045 to -0.006) and physical and sexual IPV (mean difference, -0.045; 95% CI, -0.077 to -0.013) with child socioemotional scores, but neither was statistically significant after including depressive symptoms in the model, which is consistent with mediation. Furthermore, a negative association was observed between maternal mild to severe depressive symptoms and child socioemotional development, including adjustment for IPV (mean difference, -0.073; 95% CI, -0.103 to -0.043). Harsh disciplinary practices and stimulation were not associated with child socioemotional development after adjusting for IPV, maternal depressive symptoms, and other factors. Conclusions and Relevance: The findings of this study suggest that maternal depressive symptoms may explain the negative association between IPV and child socioemotional development.

Physical punishment and child, adolescent, and adult outcomes in low- and middle-income countries: protocol for systematic review and meta-analysis.

BACKGROUND: Physical punishment at home and in schools is widespread around the world. Systematic reviews and meta-analyses have synthesized evidence, mostly from high-income countries (HICs), showing that physical punishment relates to multiple detrimental individual outcomes. Yet, less work has been done to synthesize the evidence on the association between physical punishment at home and schools and child, adolescent, and adult outcomes in low- and middle-income countries (LMICs), where more than 90% of children live and physical punishment is most socially normative and prevalent. In this manuscript, we present a protocol for a systematic review and meta-analysis on the characteristics of the research, associations, and variation in associations, between physical punishment at home and in schools and child, adolescent, and adult outcomes in LMICs. METHODS: We will conduct a review of studies published in peer-reviewed journals using quantitative methods to assess the association between physical punishment in childhood and/or adolescence and individual outcomes in LMICs. We will search for studies in 10 different databases using keywords in English, Spanish, Portuguese, Arabic, and Chinese related to physical punishment. We will extract qualitative data from the studies and the statistics needed to transform all study-level effect sizes into standardized mean difference effect sizes. For the analyses, we will employ multi-level meta-analyses to use multiple effect sizes per study and leverage within-study variation as well as between study variation using moderation analysis. Besides the meta-analyses, we will also conduct a narrative synthesis of the findings. DISCUSSION: The proposed systematic review and meta-analysis will provide timely evidence to inform global research, policy, and practice on the links between physical punishment and lifelong individual outcomes.

Prevention of violence against children in the home: an overview of reviews protocol.

BACKGROUND: Violence against children (VAC) in the home, or by household members, is a widespread problem with devastating and costly consequences for individuals and societies. In the past two decades, much research has been dedicated to the prevention of VAC in the home, in particular, in low- and- middle-income countries, but there are few systematic examinations of the growing body of literature. We present a protocol for an overview of reviews to synthesize the evidence from recent reviews on the effectiveness and characteristics of both universal and selective interventions to prevent VAC in the home or by household members. METHODS: We will conduct an overview of reviews of quantitative studies of universal and selective interventions to prevent VAC in the home published after 2000. Our outcomes will be VAC in the home (e.g., physical, sexual, or psychological violence or neglect) and drivers or direct risk factors for VAC (e.g., beliefs or attitudes towards VAC, parenting stress). We will search for reviews in multiple databases using controlled vocabularies and keywords. We will use the AMSTAR 2 to assess the quality of reviews and will extract information on outcomes, main results, and geographic distribution of primary studies, among other data. We will conduct a narrative synthesis of the findings. DISCUSSION: The proposed overview will provide timely evidence on effective strategies to prevent VAC in the home and will identify the key strengths and limitations of the current body of evidence on this topic. In doing so, we will inform future research, policy, and practice aimed at building effective strategies to prevent VAC globally. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42022304784.
