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.

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.

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.

Pathways between family SES, parent characteristics, early experiences, and child language outcomes in South Korea: A combined analysis of the family stress model and the family investment model.

Whereas previous research has examined the role that parenting and home environments play in explaining the relation between family socioeconomic status and children's language development in the United States, relatively little is known about the associations between these constructs in other cultures. This study tested an integrated model of language development within a longitudinal data set of 1,894 socioeconomically diverse Korean children (48.35% girls; > 99% native-born Korean citizens) from the first year of life (age 3-8 months) to ages 3 and 6 years. A model integrating parent and environmental characteristics from the family stress model and the family investment model that also included maternal self-efficacy and knowledge of child development was shown to adequately explain the associations between family socioeconomic status and children's language development. Implications for applying similar integrated models in international contexts are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Estimates of a multidimensional index of nurturing care in the next 1000 days of life for children in low-income and middle-income countries: a modelling study.

BACKGROUND: Nurturing care is crucial for children's ongoing development during the pre-primary education period, or the next 1000 days of life. We generated nationally representative prevalence estimates of access to ten basic indicators of nurturing care among children aged 3-4 years in low-income and middle-income countries (LMICs). METHODS: We applied multiple imputation and predictive modelling to data on children living in LMICs. Individual-level data on ten indicators were from UNICEF's Multiple Indicator Cluster Surveys and the Demographic Health Surveys Program, and we included data on all children aged 36 to 59 months for whom the surveys asked relevant questions on parenting and child development. We defined minimally adequate care as receiving at least one of two indicators in each of five dimensions of nurturing care: responsive caregiving, early learning, safety and security, nutrition, and health. We used a two-step multi-level multiple imputation procedure to address missing data across individuals, indicators, and countries. Using imputed datasets, we generated a set of expected-a-posteriori estimates of the percentage and overall number of children receiving each indicator of nurturing care, as well as overall minimally adequate care, for each country, country income grouping, and region, and across all LMICs. For the 54 countries with individual-level data on all indicators, we also produced subgroup estimates of nurturing care on the basis of household wealth, child sex, and urbanicity. FINDINGS: We included individual-level data collected between 2005 and 2019 on 426 349 children aged 3-4 years in 104 LMICs. Across the 137 LMICs considered in our modelling, we estimated that 62·0 million (90% credible interval [CrI] 51·6-71·7) children aged 3-4 years, equivalent to 25·4% (90% CrI 21·2-29·4) of that age group in LMICs, were receiving minimally adequate nurturing care at the time of assessment, leaving 181·9 million (172·2-192·3) without adequate care. Access to care was highest for nutrition (86·2% [84·2-88·2], or 210·3 million [205·4-215·1], with healthy weight), and lowest for early learning (29·3% [21·5-39·6], or 71·5 million [52·5-96·6], in early childhood care and education), responsive caregiving (29·7% [25·6-34·9], or 72·4 million [62·4-85·0], experiencing adequate stimulation from non-maternal caregivers), and safety and security (32·3% [28·3-36·7], or 78·7 million [68·9-89·5], living without physical punishment). Gaps were evident in the estimates, with 50·8% (38·3-60·7) of children from upper middle-income countries receiving minimally adequate care compared with 5·6% (4·8-6·4) in low-income countries. Within 54 countries with complete child-level data, 10·7% (10·4-10·9) of children from households in the lowest wealth quintile had access to minimally adequate care compared with 41·2% (40·7-41·7) in the highest quintile. Inequalities were also large by urbanicity (17·7% [17·5-18.0] rural vs 32·2% [31·8-32.6] urban) but smaller by child sex (23·9% [23·6-24·2] girls vs 22·1% [21·9-22·4] boys). INTERPRETATION: Most children in LMICs are not receiving minimally adequate nurturing care during the next 1000-day period. Further investments in indicator measurement and resources for preschool-age children are needed, particularly for low-income populations and in the domains of responsive caregiving, early learning, and safety and security. FUNDING: None.

An observational approach for exploring variability in young children's regulation-related skills within classroom contexts.

Prior work has conceptualized children's executive function and self-regulation skills as relatively stable across short periods of time. Grounded in long-standing contextual theories of human development, this study introduces a new observational tool for measuring children's regulatory skills across different naturally occurring situations within early childhood classrooms. Using 460 observations of 91 children (M age = 5.54 years) in 16 socio-demographically diverse Prekindergarten and Kindergarten classrooms, we found that this tool-the Regulation-Related Skills Measure (RRSM)-reliably captured observed dimensions of young children's attention control and inhibitory control, but failed to appropriately represent more "internal" regulatory processes (e.g., working memory). Associations between the RRSM and other measures of children's executive function and self-regulation (i.e., direct assessments, adult reports) were low to moderate (r = 0.03 to 0.44), suggesting these tools are likely to be complementary in that they provide overlapping but ultimately distinct information regarding children's regulatory performance. Finally, results suggested substantial within-child variation in regulatory behaviors across different situations within the classroom, with the same children demonstrating consistently stronger attention control and inhibitory control during transitions than during either teacher- or student-directed activities. These findings underscore the situationally-dependent nature of children's self-regulatory performance, with implications for both theory and practice. Future research is needed to replicate these findings in more diverse, representative samples of children.

Maternal Stress and Early Neurodevelopment: Exploring the Protective Role of Maternal Growth Mindset.

OBJECTIVE: The purpose of this study was to test associations between maternal stress, maternal mindset, and infant neurodevelopment at 12 months of age. Specifically, we sought to examine the extent to which maternal growth mindsets may serve to attenuate the negative associations between maternal stress and infants' neurodevelopment. METHODS: The current exploratory study leverages data from a longitudinal cohort study following mother-infant dyads. Maternal-perceived stress, maternal mindset, and infant electroencephalography (EEG) recordings were collected when infants were 12 months of age. The final analytic sample included 33 dyads. RESULTS: Results revealed no statistically significant main effects of maternal stress or maternal mindset for any of the infant EEG frequency band outcomes. After including interactions between maternal stress and mindset, statistically significant positive interactions were detected for all EEG frequency bands. Simple slope tests revealed significant negative associations between maternal stress and each of the 6 EEG frequency bands for mothers with more fixed-oriented mindsets. Associations between maternal stress and infant EEG outcomes for mothers with more growth-oriented mindsets did not differ from 0. CONCLUSION: These findings suggest that infants raised by mothers with growth mindsets may be protected against the neurodevelopmental consequences of higher maternal stress.

Measuring and forecasting progress in education: what about early childhood?

A recent Nature article modelled within-country inequalities in primary, secondary, and tertiary education and forecast progress towards Sustainable Development Goal (SDG) targets related to education (SDG 4). However, their paper entirely overlooks inequalities in achieving Target 4.2, which aims to achieve universal access to quality early childhood development, care and preschool education by 2030. This is an important omission because of the substantial brain, cognitive and socioemotional developments that occur in early life and because of increasing evidence of early-life learning's large impacts on subsequent education and lifetime wellbeing. We provide an overview of this evidence and use new analyses to illustrate medium- and long-term implications of early learning, first by presenting associations between pre-primary programme participation and adolescent mathematics and science test scores in 73 countries and secondly, by estimating the costs of inaction (not making pre-primary programmes universal) in terms of forgone lifetime earnings in 134 countries. We find considerable losses, comparable to or greater than current governmental expenditures on all education (as percentages of GDP), particularly in low- and lower-middle-income countries. In addition to improving primary, secondary and tertiary schooling, we conclude that to attain SDG 4 and reduce inequalities in a post-COVID era, it is essential to prioritize quality early childhood care and education, including adopting policies that support families to promote early learning and their children's education.

Measuring early childhood development: considerations and evidence regarding the Caregiver Reported Early Development Instruments.

Reflecting a burgeoning political interest in supporting young children around the world, global demand for reliable, valid, and scalable assessments of early childhood development (ECD) is on the rise. One of the more popular sets of tools for measuring the ECD of children under age 3 is the Caregiver Reported Early Development Instruments (CREDI), which includes both a long form for research and evaluation and a short form for population-level monitoring. In this commentary, we describe the goals and limitations of the CREDI, research to support its use as a population-level ECD instrument, as well as the major gaps in its evidence base. We also discuss how the work of Alderman and colleagues (in this issue) addresses some of these outstanding gaps, highlighting several critical areas for future research.

Physical punishment as a predictor of early cognitive development: Evidence from econometric approaches.

This study estimates the effect of physical punishment on the cognitive development of 1,167 low-income Colombian children (Mage = 17.8 months old) using 3 analytic strategies: lagged-dependent variables, a difference-in-differences-like approach (DD), and a novel strategy combining matching with a DD-like approach. Across approaches, physical punishment at ages 9-26 months predicted reductions in children's cognitive development of 0.08-0.21 SD at ages 27-46 months. These results, plus null results of falsification tests, strengthen the argument that physical punishment leads to slower cognitive growth and illustrate the utility of alternative statistical methods to reduce problems of selection bias in developmental research.

Maternal knowledge, stimulation, and early childhood development in low-income families in Colombia.

Theoretical models assume that parental knowledge about child development and caregiving motivates parental stimulation, shaping child development. Evidence supporting these models is scarce in low- and middle-income countries (LMICs). This study tests the relations between maternal knowledge, stimulation, and child development in a Colombian sample of 1,277 low-income mothers and their children under the age of five. Mothers showed diverse knowledge about child development and caregiving. Moreover, maternal knowledge when children were 9-26 months old indirectly predicted growth in children's cognitive, receptive language, and gross motor skills at ages 27-46 months, partially through maternal engagement in stimulating activities with the child.

Maternal, paternal, and other caregivers' stimulation in low- and- middle-income countries.

BACKGROUND AND OBJECTIVES: Globally, studies have shown associations between maternal stimulation and early child development. Yet, little is known about the prevalence of paternal and other caregivers' stimulation practices, particularly in low- and- middle-income countries (LMICs). METHODS: Data from the Multiple Indicators Cluster Survey (MICS) and the Demographic and Health Survey (DHS) were combined across 62 LMICs (2010-2018). The sample included 205,150 mothers of children aged 3 and 4 years. High levels of stimulation were defined as caregiver engagement in at least 4 out of 6 possible activities with the child. The proportion of mothers, fathers, and other caregivers providing high levels of stimulation was calculated by country, region, and for the whole sample. Socioeconomic disparities within and between countries were estimated. RESULTS: On average, 39.8% (95% CI 37.4 to 42.2) of mothers, 11.9% (95% CI 10.1 to 13.8) of fathers, and 20.7% (95% CI 18.4 to 23.0) of other adult caregivers provided high levels of stimulation. Stimulation varied by region, country income group, and Human Development Index (HDI), with higher levels of maternal and paternal-but not other caregivers'-stimulation in high-income and high-HDI countries. Within countries, stimulation levels were, on average, lower in the poorest relative to the richest households, and some but not all countries exhibited differences by child sex (i.e., boys vs. girls) or area (i.e., urban vs. rural). CONCLUSIONS: Results suggest a need for intervention efforts that focus on increasing caregiver stimulation in LMICs, particularly for fathers and in low-income contexts.

Intimate Partner Violence, Maternal and Paternal Parenting, and Early Child Development.

BACKGROUND AND OBJECTIVES: Previous research has demonstrated associations between maternal experience of intimate partner violence (IPV) and a range of adverse outcomes among women and their young children. However, few studies have examined the associations between maternal experience of IPV and early child development (ECD) outcomes in low- and middle-income countries (LMIC). Our objectives in this study were to examine the association between IPV victimization and ECD and assess whether the association was mediated by maternal and paternal stimulation. METHODS: We combined cross-sectional data from the Demographic and Health Surveys for 15 202 households representing mothers and fathers of children aged 36 to 59 months in 11 LMIC. We used multivariable linear regression models to estimate the association between IPV victimization in the year preceding the survey and ECD, which we measured using the Early Child Development Index. We used path analysis to determine if the association between IPV victimization and ECD was mediated through maternal and paternal stimulation. RESULTS: After adjusting for sociodemographic variables, IPV victimization was negatively associated with ECD (ß = -.11; 95% confidence interval = -.15 to -.07). Path analysis indicated that the direct association between IPV victimization and ECD was partially and independently mediated through maternal and paternal stimulation. CONCLUSIONS: Interventions that include components to prevent IPV may be effective for improving ECD in LMIC.

Measuring early childhood development in Brazil: validation of the Caregiver Reported Early Development Instruments (CREDI) / Medição do desenvolvimento na primeira infância no Brasil: validação dosInstrumentos sobre o Desenvolvimento na Primeira Infância Relatado por Cuidadores(CREDI)

Abstract Objective The present study aims to analyze the psychometric properties and general validity of the Caregiver Reported Early Development Instruments (CREDI) short form for the population-level assessment of early childhood development for Brazilian children under age 3. Method The study analyzed the acceptability, test-retest reliability, internal consistency and discriminant validity of the CREDI short-form tool. The study also analyzed the concurrent validity of the CREDI with a direct observational measure (Inter-American Development Bank's Regional Project on Child Development Indicators; PRIDI). The full sample includes 1,265 Brazilian caregivers of children from 0 to 35 months (678 of which comprising an in-person sample and 587 an online sample). Results Results from qualitative interviews suggest overall high rates of acceptability. Most of the items showed adequate test-retest reliability, with an average agreement of 84%. Cronbach's alpha suggested adequate internal consistency/inter-item reliability (α > 0.80) for the CREDI within each of the six age groups (0-5, 6-11, 12-17, 18-23, 24-29 and 30-35 months of age). Multivariate analyses of construct validity showed that a significant proportion of the variance in CREDI scores could be explained by child gender and family characteristics, most importantly caregiver-reported cognitive stimulation in the home (p < 0.0001). Regarding concurrent validity, scores on the CREDI were significantly correlated with overall PRIDI scores within the in-person sample at r = 0.46 (p < 0.001). Conclusions The results suggested that the CREDI short form is a valid, reliable, and acceptable measure of early childhood development for children under the age of 3 years in Brazil.

Método O estudo analisou a aceitabilidade, a confiabilidade teste-reteste, a consistência interna e a validade discriminante da ferramenta CREDI. O estudo também analisou a validade concorrente do CREDI com uma medida observacional direta (Projeto Regional sobre os Indicadores de Desenvolvimento na Infância do Banco Interamericano de Desenvolvimento; PRIDI). A amostra total inclui 1.265 cuidadores brasileiros de crianças de 0 a 35 meses (678 em uma amostra presencial e 587 em uma amostra on-line). Resultados Os resultados das entrevistas qualitativas sugerem altas taxas gerais de aceitabilidade. A maior parte dos itens mostrou confiabilidade teste-reteste adequada, com concordância média de 84%. O coeficiente alfa de Cronbach sugeriu consistência interna/confiabilidade entre itens (α > 0,80) para o CREDI em cada uma das seis faixas etárias (0-5 α = 6-11, 12-17, 18-23, 24-29 e 30-35 meses de idade). As análises multivariadas da validade do constructo mostraram que uma proporção significativa da variação nas pontuações do CREDI pode ser explicada pelo sexo da criança e pelas características familiares, mais importante o estímulo cognitivo em casa relatado pelo cuidador (p < 0,0001). Com relação à validade concorrente, as pontuações do CREDI foram significativamente correlacionadas às pontuações gerais do PRIDI na amostra presencial em r = 0,46 (p < 0,001). Conclusões Os resultados sugerem que o formulário curto CREDI é uma medida válida, confiável e aceitável de desenvolvimento na primeira infância para crianças com menos de três anos no Brasil.

Contextual and socioeconomic variation in early motor and language development.

OBJECTIVE: To compare early motor and language development of children <3 years of age growing up in high-income and low-income contexts. DESIGN: Cross-sectional study. SETTING: We analysed differences in motor and language skills across study sites in Cambodia, Chile, Ghana, Guatemala, Lebanon, Pakistan, the Philippines and the USA. MAIN OUTCOME MEASURE: Cognitive and language development assessed with the Caregiver Reported Early Development Instruments (CREDI) tool. RESULTS: 4649 children aged 0-35 months (mean age=18 months) were analysed. On average, children in sites with a low Human Development Index (HDI) had 0.54 SD (95% CI -0.63 to -0.44) lower CREDI motor scores and 0.73 SD (95% CI -0.82 to -0.64) lower language scores than children growing up in high HDI sites. On average, each unit increase in national log income per capita was associated with a 0.77-month (95% CI -0.93 to 0.60) reduction in the age of motor milestone attainment and a reduction in the age of language milestone attainment of 0.55 months (95% CI -0.79 to -0.30). These observed developmental differences were not universal: no developmental differences across sites with highly heterogeneous socioeconomic contexts were found among children growing up in households with highly educated caregivers providing stimulating early environments. CONCLUSION: Developmental gaps in settings with low HDI are substantial on average, but appear to be largely attributable to differences in family-level socioeconomic status and caregiving practices. Programmes targeting the most vulnerable subpopulations will be essential to reduce early life disparities and improve long-run outcomes.

Early childhood exposure to non-violent discipline and physical and psychological aggression in low- and middle-income countries: National, regional, and global prevalence estimates.

BACKGROUND: Advocates for children's rights have recommended the elimination of all forms of violent discipline given its detrimental effects on children's development. Yet, little is known about the global prevalence of various forms of discipline, including physical and psychological aggression, as well as alternative forms of non-violent discipline, especially in low- and middle-income countries (LMICs). OBJECTIVE: This study aims to obtain national, regional, and global prevalence estimates of the percentage and number of 2- to- 4-y-olds in LMICs exposed to these disciplinary practices by their caregivers. PARTICIPANTS AND SETTING: We use data collected between 2010 and 2016 from 107,063 2- to- 4-y-old children living in 49 LMICs as part of the Multiple Indicator Cluster Survey (MICS). METHODS: Using the best-fitting model based on cross-validation techniques, we performed predictive modeling to generate country-level prevalence estimates for 131 LMICs in 2013, as well as 95% confidence intervals around these estimates. RESULTS: We estimate that 296.2 million 2- to- 4-y-olds (95% CI 256.9, 300.9) were exposed to non-violent discipline in 2013, which corresponds to 83.9% of the population. Furthermore, 220.4 million (95% CI 138.1, 283.7) and 230.7 million (95% CI 128.4, 300.6) children were exposed to aggressive physical and psychological discipline, respectively, which corresponds to prevalence of 62.5% and 65.4%. We also identify a high heterogeneity in the estimates across and within regions, finding a higher prevalence of both violent disciplinary methods in South Asia and Sub-Saharan Africa. CONCLUSIONS: These results suggest the need for new policies and programs to minimize violent discipline around the world.
