Peer relationships and depressive symptomatology in boys at puberty

The physical changes of puberty coincide with an increase in the salience of peer relationships and a growing risk for depression and other forms of psychopathology. Previously, we reported that pubertal tempo, defined as a child's rate of intraindividual change in pubertal status (measured using parent-reported Tanner stages; Marshall & Tanner, 1970), was associated with changes in boys'--but not girls'--depressive symptoms over and above effects explained by pubertal timing (Mendle, Harden, Brooks-Gunn, & Graber, 2010). The present study extends this previous research by examining changes in the quality of peer relationships in the association between individual differences in pubertal development and change in boys' depressive symptoms. Boys (N = 128, M = 9.61 years, SD = 0.70, at Time 1) were recruited from public schools and assessed annually for 4 years. Results from latent growth curve models indicated that earlier pubertal timing and more rapid pubertal tempo were associated with greater decrements in the quality of boys' peer relationships. After accounting for the association between change in peer relationships and depressive symptoms, the direct effects of pubertal timing and tempo on depressive symptoms were no longer significant. These results highlight a multifaceted approach to studying puberty and emphasize how social mechanisms may intersect with biological risk to produce psychological distress.     

Poverty,ethnicity, and risk of obesity among low birth weight infants

The independent and joint effects of family and neighborhood poverty and ethnicity upon weight trajectories from age two to six-and-a-half were examined using data from the Infant Health and Development Program (N = 985), an early intervention program for low birth weight children and families. At age two, family poverty was associated with higher body mass index (BMI), whereas neighborhood poverty and ethnicity were not. Over time, the BMI of toddlers from poor and near poor neighborhoods increased nonlinearly, while those from nonpoor neighborhoods remained stable. BMIs of Hispanic-American toddlers increased steadily over time, unlike African-American and Anglo-American toddlers. Although initially similar, over time African-American toddlers' BMIs increased more rapidly than Anglo-American toddlers. Family and neighborhood poverty and ethnicity were associated with BMI. More work is needed on how poverty and ethnicity contribute to differences in early weight gain in conjunction with sociocultural and environmental factors in the home and community.     

Does the Amount of Participation in Afterschool Programs Relate to Developmental Outcomes? A Review of the Literature

Contrary to the findings from previous reviews we found little support for the general notion that greater amounts of participation in afterschool programs was related to academic, behavioral, or socio-emotional outcomes. However, some relationships did emerge depending on how participation was conceptualized and measured, and the methodology used to assess the relationship between participation and outcomes. For example, some benefits occurred when participants with high levels of participation were compared to non-participants, not when they were compared to other program participants. Several suggestions are offered to improve future research on the relationship between aspects of participation and developmental outcomes.     

Head Start and urban children's school readiness: a birth cohort study in 18 cities

We used longitudinal data from a birth cohort study, the Fragile Families and Child Wellbeing Study, to investigate the links between Head Start and school readiness in a large and diverse sample of urban children at age 5 (N = 2,803; 18 cities). We found that Head Start attendance was associated with enhanced cognitive ability and social competence and reduced attention problems but not reduced internalizing or externalizing behavior problems. These findings were robust to model specifications (including models with city-fixed effects and propensity-scoring matching). Furthermore, the effects of Head Start varied by the reference group. Head Start was associated with improved cognitive development when compared with parental care or other nonparental care, as well as improved social competence (compared with parental care) and reduced attention problems (compared with other nonparental care). In contrast, compared with attendance at pre-kindergarten or other center-based care, Head Start attendance was not associated with cognitive gains but with improved social competence and reduced attention and externalizing behavior problems (compared with attendance at other center-based care). These associations were not moderated by child gender or race/ethnicity.     

Family processes as pathways from income to young children's development

A variety of family processes have been hypothesized to mediate associations between income and young children's development. Maternal emotional distress, parental authoritative and authoritarian behavior (videotaped mother-child interactions), and provision of cognitively stimulating activities (Home Observation for Measurement of the Environment [HOME] scales) were examined as possible mediators in a sample of 493 White and African American low-birth-weight premature infants who were followed from birth through age 5. Cognitive ability was assessed by standardized test, and child behavior problems by maternal report, when the children were 3 and 5 years of age. As expected, family income was associated with child outcomes. The provision of stimulating experiences in the home mediated the relation between family income and both children's outcomes; maternal emotional distress and parenting practices mediated the relation between income and children's behavior problems.     

Links Between Motor Control and Classroom Behaviors: Moderation by Low Birth Weight

It is unclear from past research on effortful control whether one of its components, motor control, independently contributes to adaptive classroom behaviors. The goal of this study was to identify associations between early motor control, measured by the walk-a-line task at age 3, and teacher-reported learning-related behaviors (approaches to learning and attention problems) and behavior problems in kindergarten classrooms. Models tested whether children who were vulnerable to poorer learning behaviors and more behavior problems due to having been born low birth weight benefited more, less, or the same as other children from better motor control. Data were drawn from the national Fragile Families and Child-Wellbeing Study (n = 751). Regression models indicated that motor control was significantly associated with better approaches to learning and fewer behavior problems. Children who were low birth weight benefitted more than normal birth weight children from better motor control with respect to their approaches to learning, but equally with respect to behavior problems. Additionally, for low but not normal birth weight children, better motor control predicted fewer attention problems. These findings suggest that motor control follows a compensatory model of development for low birth weight children and classroom behaviors.

A randomized study of neighborhood effects on low-income children's educational outcomes

Experimental data from the Moving to Opportunity for Fair Housing Demonstration were used to examine (a) if moving from high- to low-poverty neighborhoods (via randomization) was associated with low-income minority children's achievement, grade retention, and suspensions/expulsions; (b) if moving minimized gender differences in these outcomes; and (c) potential mediators of observed program effects. Data on school-age children (mean age = 11.79 years, SD = 3.26) were obtained from standardized assessments and parent and adolescent interviews during the New York City site's 3-year follow-up evaluation (N = 588). Moving to low-poverty neighborhoods had positive effects on 11-18-year-old boys' achievement scores compared with those of their peers in high-poverty neighborhoods. These male adolescents' scores were comparable to females' scores, whereas male adolescents in high-poverty neighborhoods scored 10 points lower than female peers. Homework time and school safety partially accounted for program effects. From a policy perspective, the program benefited disadvantaged male adolescents at high risk for dropping out of school.     

Do parent-child relationships change during puberty?

This article reviews changes in parent-child relationships during puberty, emphasizing the developmental processes that might be implicated in these changes. Evidence suggests increases in conflict and less warm interactions in relationships between parents and children during puberty. Changes are assumed to be short term, although little longitudinal research has directly addressed the issue of long-lasting effects. Other developmental changes occurring for the adolescent, the parent, or both (such as social cognitive or self-definitional change), as well as other relationship changes, personality characteristics, and the sheer number of life events or transitions have all been posited as potential contributors to changes in the parent-child relationship for young adolescents. These possible contributors, however, have seldom been studied in conjunction with pubertal changes. Such integrative research is necessary to test various models through which puberty, social relationships, social cognitive, self-definitional, and other processes influence one another and are influenced by one another during the transition to adolescence.
