We present the 2-year experimental mixed-methods findings of a two-generation English as a second language (ESL) program. This program combines a high-dosage, child-oriented curriculum for parents with Head Start for children in addition to family-based supportive services. At baseline and after 2 years, 189 Latinx and Zomi immigrant parents comple...

Economic disadvantage has often been associated with poorer performance on measures of early childhood development. However, the causal impacts of income on child development remain unclear. The present study uses data from the Baby’s First Years randomized control trial to identify the causal impact of unconditional cash transfers on maternal repo...

This study explores the effects of the two‐generation program Career Advance —which combines education and training for parents in healthcare with Head Start for children—on children's academic, language, mathematics, and inhibitory control followed for 3 years. The sample (collected in Tulsa, Oklahoma from 2011 to 2018) includes 147 children in th...

Research on early language input and socioeconomic status typically relies on correlations in small convenience samples. Using data from Baby's First Years, this paper assesses the causal impact of monthly, unconditional cash transfers on child‐directed speech and child vocalizations among a large, racially diverse sample of low‐income U.S. mothers...

Gender-Sexuality Alliances (GSAs) and inclusive school policies and practices that affirm youth with minoritized sexual orientations or gender identities (e.g., lesbian, gay, bisexual, transgender, queer youth; LGBTQ+ youth) are two sources of support for LGBTQ+ youth that could promote school belonging. The current study tested a three-level multi...

How does unconditional income for families in poverty affect parental investments for their young children? Mothers in four US metropolitan areas were randomized to receive a monthly unconditional cash transfer of either $333 per month (high) or $20 per month (low) for the first several years after childbirth. During the first 3 years, high-cash gi...

Interest in two‐generation approaches to improve the developmental outcomes of children and their caregivers and the economic well‐being of families has increased amid persistent child and family poverty worldwide. Grounded in a dual developmental science perspective and the theory of linked lives, these approaches maximize developmental potential...

Gender sexuality alliances (GSAs) represent consciousness‐raisings that hold potential for critical consciousness development in youth. In this study, we focus on critical reflection—the understanding that oppression is structured and maintained by human action. We engage intersectionality as our analytical framework and analyze both student interv...

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, Pare...

Leveraging data from a longitudinal study of Chinese families ( n = 364), this research aims to understand the role of secure base script knowledge as a cognitive mechanism by which early caregiving experiences inform adolescents’ friendship quality and feelings of loneliness. Results showed that observed maternal sensitivity at 14 and 24 months ol...

A growing body of literature shows that adherence to some aspects of Western masculinity norms, including the suppression of emotional vulnerability, avoidance of seeking support from others, and exaggerated physical toughness, is associated with poorer psychological and social outcomes. While existing research suggests that parental gender beliefs...

Relational theories of human development explain how stereotypes and their underlying ideologies thwart social connections that are fundamental for individuals to thrive, especially in early adolescence. Intervention research to address this crisis of connection is still emergent and active listening is one promising strategy to this end; however,...

The climate crisis encompasses a constellation of risks that threaten human livelihoods, well-being, and survival globally. In this article, we present a new framework based on bioecological and dynamic systems perspectives, and on evidence for conceptualizing how the distinctive dual time frame of both acute (e.g., extreme weather events) and chro...

Importance Children experiencing poverty are more likely to experience worse health outcomes, including injury, chronic illness, worse nutrition, and poorer sleep. The extent to which poverty reduction improves these outcomes is unknown. Objective To evaluate the effect of a 3-year, monthly unconditional cash transfer on health, nutrition, sleep,...

Importance: Children experiencing poverty are more likely to experience worse health outcomes during the first few years of life, including injury, chronic illness, worse nutrition, and poorer sleep. The extent to which a poverty reduction intervention improves children's health, nutrition, sleep, and healthcare utilization is unknown. Objective: T...

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...

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; M age = 51.5; 49% girls). Results from random‐effects and more conservative child‐fixed effects models indicate that across these stu...

We present results of a randomized control trial of a two-generation English as a Second Language (ESL) program in which all families participated in Head Start while treatment parents also enrolled in a high dosage, family-focused ESL curriculum with supportive services. Examining 197 parent-child dyads among Spanish- (89%) and Zomi-speaking (11%)...

Objective: Depression disparities between heterosexual youth and lesbian, gay, bisexual, queer, and other non-heterosexual (LGBQ+) youth are robust and linked to discrimination in schools. Advocacy by school-based Gender-Sexuality Alliances (GSAs) to raise awareness of LGBQ+ issues and to counteract discrimination may reduce these disparities with...

Purpose: Our purpose was to assess the association between Gender-Sexuality Alliances (GSAs) advisors' self-efficacy to address transgender issues and their students' depressive symptoms, by students' gender identity (i.e., transgender vs. cisgender). We predict that higher advisor self-efficacy will be associated with decreases in student depressi...

Worldwide millions of families with children residing with low or precarious income receive some form of unconditional cash income. Nevertheless economists have limited causal evidence on how families receiving unconditional income would spend those funds. We examine financial and time investments in infants among families living in poverty from a...

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 system...

Gender-Sexuality Alliances (GSAs) are school clubs for LGBTQ + youth and peer allies to support one another. This 8-week weekly diary study considered whether a youth’s positive and negative affect during a given week could be predicted by experiences in their most recently attended GSA meeting. Ninety-nine GSA members (Mage = 15.90, SD = 1.33; 79%...

Grandparents are an important source of social support for parents’ adjustment to parenthood. In this study, we examine how urban Chinese mothers experience grandmother support in relation to their parenting stress, based on the interview and survey data of a sample of 352 first-time mothers with 14-month-old children living in Nanjing, China. We f...

Previous research indicates that parental emotion socialization (ES) practices play important roles in adolescents’ social and emotional development. However, longitudinal studies testing bidirectional effects are relatively scarce. Additionally, most studies have focused on people from Western societies. In the current three-year, multi-informant,...

SYNOPSIS This article focuses on the demand side of parenting programs, in addition to the traditionally studied supply side and argues that a path to scale of parenting programs must align and equally acknowledge supply and demand side domains and characteristics, whereas historically they are addressed in silos. Evidence suggests that a core set...

Background Policy debates over anti-poverty programs are often marked by pernicious stereotypes suggesting that direct cash transfers to people residing in poverty encourage health-risking behaviors such as smoking, drinking, and other substance use. Causal evidence on this issue is limited in the U.S. Given the prominent role of child allowances a...

Significance This study demonstrates the causal impact of a poverty reduction intervention on early childhood brain activity. Data from the Baby’s First Years study, a randomized control trial, show that a predictable, monthly unconditional cash transfer given to low-income families may have a causal impact on infant brain activity. In the context...

Family engagement in early learning and education is considered a key predictor of children's development. However, little is known about the link between family engagement in early learning opportunities in sociocultural diverse contexts, particularly in low- and-middle-income countries. This study examined the associations of family engagement in...

Drawing on survey and interview data from mothers of 14-month infants in Nanjing, China, we explore women’s job trajectories as they juggle work and family responsibilities. Four profiles that emerge among our sample of 371 mothers (high stability, rapid cyclers, high-paid wage-growth, and intermittent) reflected not only their work career trajecto...

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 childh...

What is breastfeeding “success”? In this article, we challenge the traditional biomedical definition, instead centering visions of success described by breastfeeding mothers themselves. Using semi-structured interviews, quantitative surveys, and written narratives of 38 first-time mothers in the United States, we describe five common pathways throu...

Childhood economic disadvantage is associated with lower cognitive and social-emotional skills, reduced educational attainment, and lower earnings in adulthood. Despite these robust correlations, it is unclear whether family income is the cause of differences observed between children growing up in poverty and their more fortunate peers or whether...

National‐level monitoring of quality of early childhood education (ECE) is key to achieving inclusive and equitable education. Most countries report structural quality while process characteristics are rarely observed at the national level. This study examined the associations between ECE and children's development in a middle‐income country using...

This study examined toddlers' autonomy- and connectedness-oriented behaviors and mothers' encouragement of autonomy and connectedness in two cohorts (1995 and 2008) in urban China. Observational data were collected from Chinese children and their mothers in a laboratory free play session. The results showed that compared with children in the 1995 c...

Despite a recent call for an expanded research agenda that is more likely to produce tangible societal reductions in inequality, efforts to articulate how social scientists can actually pursue this agenda remain few and far between. The central question this article addresses is, What can social scientists do to deliver the forms of knowledge that...

Objective: To assess whether in-hospital infant formula supplementation impacts later successful breastfeeding among healthy mother-infant dyads in the United States who are not intending to exclusively use infant formula. Study Design: Using secondary analysis of a national longitudinal survey (Infant Feeding Practices Study II, n = 2,399), we es...

Gender & Sexuality Alliances (GSAs) are school‐based clubs that support youth of diverse sexual orientations and gender identities. As identity‐centered spaces, GSAs could also foster discussions related to race and immigration (i.e., race and immigration talk). We conducted semi‐structured interviews from 2016 to 2018 with 38 GSA members (ages 13–...

A comprehensive evidence-based framework is needed to guide policies and programmes that enable children and adolescents to accrue the human capital required to meet the Sustainable Development Goals (SDGs). This paper proposes a comprehensive, multisectoral, multilevel life-course conceptualisation of human capital development by building on the N...

Parent-child reminiscing talk about positive and negative events provides children with unique opportunities to develop emotion competence. Very little work has involved families from low-income households and ethnically diverse backgrounds. We examined: 1) event valence (positive vs. negative) and ethnic differences in mother-child reminiscing tal...

Youth–adult partnerships are intentionally cultivated intergenerational relationships characterized by shared power among youth and adults. Although youth–adult partnerships (Y‐APs) are widely adopted as a strategy to promote key positive development outcomes in youth service organizations, research documents various challenges that affect their qu...

In a time of unprecedented polarization in the United States, particularly concerning immigration, schools are uniquely positioned to help students understand the consequences of drastic policy changes. Beyond formal settings such as social studies classes, extracurricular activities may be important for fostering discussions about sociohistorical...

Research among sexual and gender minority (SGM) youth has suggested associations between Gender-Sexuality Alliance (GSA) involvement and better health. Emergent research has similarly demonstrated associations between family support and general well-being among SGM youth. However, the trait of bravery has received little attention in this literatur...

Belonging to a school Gender and Sexuality Alliance (GSA) is associated with lower substance use among LGBTQ+ youth. However, it is unknown whether GSA participation facilitates access to resources for substance use concerns. Using longitudinal data from 38 Massachusetts high schools, we compared sources of support for substance use concerns listed...

An estimated 12 million girls aged 15–19 years, and 777,000 girls younger than 15 give birth globally each year. Contexts of war and displacement increase the likelihood of early marriage and childbearing. Given the developmentally sensitive periods of early childhood and adolescence, adolescent motherhood in conflict-affected contexts may put a fa...

Extracurricular groups can promote healthy development, yet the literature has given limited attention to indirect associations between extracurricular involvement and mental health or to sexual and gender minority youth. Among 580 youth (Mage = 15.59, range = 10–20 years) and adult advisors in 38 Gender‐Sexuality Alliances (GSAs), multilevel struc...

Though there is an expanding field of research on public prekindergarten, there is a relatively little comprehensive investigation into what public prekindergarten costs. We address some of the absences in the literature by analyzing public-sector expenditures for the city of Boston’s public prekindergarten program, a particularly high-quality prog...

Two‐generation human capital programs seek to promote the education of parents and children simultaneously. This study examines relations between family participation in CareerAdvance, which recruits parents of Head Start children into a workforce training program, and children’s Head Start attendance. The sample included 293 children (on average 4...

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) a...

Parent–child separation occurs for many reasons, both involuntary and voluntary. We review the effects on children and youth of parent–child separation due to several of the most common reasons that are responsible for the growth in this family circumstance worldwide. These include early institutionalization; war, persecution, and conflict; separat...

Objective: This study explores the transformation of patrilineality in grandparents' child care in China, which was traditionally oriented almost exclusively toward caring for sons' children. Background: Since China's 1949 revolution, grandparent child care has undergone rapid transformation, shifting from strongly patrilateral to bilateral or even...

Research Findings: This study uses data from a comprehensive meta-analytic database of early childhood education (ECE) program evaluations published between 1960 and 2007 in the United States to examine the incremental effects of adding enhancement program components to ECE programs on children’s cognitive abilities, pre-academic skills, behavioral...

Mixed-status families (families with at least one undocumented member) in the United States are experiencing a crisis of historic depth and scope due to recent changes in immigration enforcement policy. They experience unique challenges in their home-school partnerships because of an unprecedented policy-driven climate of fear affecting their every...

We examined associations between maternal writing support, math support, and directiveness and children’s literacy and math outcomes. Participants were 208 African American, Dominican, Mexican, and Chinese mothers and their first-grade children from low-income households. Mothers were video-recorded playing a grocery game with their children (i.e.,...

School-based extracurricular settings could promote dialogue on sociopolitical crises. We considered immigration discussions within gender-sexuality alliances (GSAs), which address multiple systems of oppression. Among 361 youth and 58 advisors in 38 GSAs (19 in 2016–2017/Year 1; 19 in 2017–2018/Year 2), youth in Year 1 reported increased discussio...

Two-generation human capital programs for families provide education and workforce training for parents simultaneously with education for children. This study uses a quasi-experimental design to examine the effects of a model two-generation program, CareerAdvance, which recruits parents of children enrolled in Head Start into a health care workforc...

In Colombia, the national law De Cero a Siempre (DCAS) provides a framework for holistic and integrated early childhood development and education for all children. Against the backdrop of the United Nations’ Sustainable Development Goals and the DCAS policy objectives, Colombia set out to apply a comprehensive measure to track the quality of early...

An unprecedented half of the world’s 57 million out of school children live in conflict-affected countries, and 50% of children of primary-school-age are not attending school. In addition, the unauthorized status of many refugees and migrants worldwide is associated with experiences of social exclusion as access to employment and social services ar...

Relatively little research has addressed whether conceptual frameworks of early learning generalize across different national contexts. This article reports on a cross-country measurement invariance analysis of the International Development and Early Learning Assessment (IDELA). The IDELA is a direct assessment tool for 3- to 6-year-old children, i...

Little is known about parents’ book-sharing styles in indigenous communities undergoing social and cultural change. This study investigated Guatemalan Mayan parents’ book-sharing styles and their relation to parents’ schooling experience and children's narrative contributions. Thirty parents and their first-grade children (ages 7–9) were audiotaped...

Drawing from a person‐environment fit framework, we identified profiles of youth in gay–straight alliances (GSAs) based on the extent to which they received information/resources, socializing/support, and advocacy opportunities in their GSAs and the extent to which this matched what they desired from their GSA along these three functions. Further,...

Patterns of breastfeeding over time are not currently well understood. Limited qualitative and quantitative evidence suggests that there may be latent subgroups of mothers in the United States following very different trajectories of breast milk provision for their infants. This study used a quantitative modelling method (group-based trajectory mod...

Audio Interview Interview with Dr. Breanne Grace on immigrant and refugee health and the effects of systematic personal, social, and institutional instability. (09:02)Download The Trump administration is aiming to expand the criteria for deeming an immigrant likely to become a “public charge.” Such a change would have important consequences for acc...

Gay–Straight Alliances (GSAs) aspire to empower youth to address multiple systems of oppression, including those affecting transgender and racial/ethnic minority youth, yet there is little indication of factors contributing to youths’ self-efficacy to do so. We examined individual and group factors predicting self-efficacy to address transgender an...

Young children living in conditions of war, disaster, and displacement are at high risk for developmental difficulties that can follow them throughout their lives. While there is robust evidence supporting the need for early childhood development (ECD) in humanitarian settings, implementation of ECD programming remains sparse, largely due to the la...

Background/Aims: For mothers in high-income country contexts, infant feeding represents one of the most fundamental and challenging aspects of the transition to parenthood. We present a specific theoretical model, based on life course theory principles, to explicate how the maternal ecology influences breastfeeding behaviors throughout the early pa...
