Introduction The New Jersey Kids Study (NJKS) is a transdisciplinary statewide initiative to understand influences on child health, development, and disease. We conducted a mixed-methods study of project planning teams to investigate team effectiveness and relationships between team dynamics and quality of deliverables. Methods Ten theme-based working groups (WGs) (e.g., Neurodevelopment, Nutrition) informed protocol development and submitted final reports. WG members ( n = 79, 75%) completed questionnaires including de-identified demographic and professional information and a modified TeamSTEPPS Team Assessment Questionnaire (TAQ). Reviewers independently evaluated final reports using a standardized tool. We analyzed questionnaire results and final report assessments using linear regression and performed constant comparative qualitative analysis to identify central themes. Results WG-level factors associated with greater team effectiveness included proportion of full professors ( β = 31.24, 95% CI 27.65–34.82), team size ( β = 0.81, 95% CI 0.70–0.92), and percent dedicated research effort ( β = 0.11, 95% CI 0.09–0.13); age distribution ( β = −2.67, 95% CI –3.00 to –2.38) and diversity of school affiliations ( β = –33.32, 95% CI –36.84 to –29.80) were inversely associated with team effectiveness. No factors were associated with final report assessments. Perceptions of overall initiative leadership were associated with expressed enthusiasm for future NJKS participation. Qualitative analyses of final reports yielded four themes related to team science practices: organization and process, collaboration, task delegation, and decision-making patterns. Conclusions We identified several correlates of team effectiveness in a team science initiative's early planning phase. Extra effort may be needed to bridge differences in team members' backgrounds to enhance the effectiveness of diverse teams. This work also highlights leadership as an important component in future investigator engagement.

Children born small for gestational age (SGA) may be at risk for earlier puberty and adverse long-term health sequelae. This study investigates associations between SGA and age at menarche using secondary data on 1,027 female children in a population-based U.S. birth cohort that over-sampled non-marital births, which in the U.S. is a policy-relevant population. SGA was defined as <10th percentile of weight for gestational age compared to the national U.S. distribution. We estimated unadjusted and adjusted Ordinary Least Squares (OLS) models of associations between SGA and age at menarche in years, as well as unadjusted and adjusted logistic regression models of associations between SGA and early menarche (before age 11). SGA was not significantly associated with earlier age at menarche, even when adjusting for maternal sociodemographic characteristics, prenatal smoking, and maternal pre-pregnancy overweight and obesity. Similarly, SGA was not significantly associated with the odds of menarche occurring before age 11. However, maternal non-Hispanic Black race-ethnicity, Hispanic ethnicity, and pre-pregnancy obesity all had independent associations with average earlier age at menarche and menarche before age 11. Thus, maternal risk factors appear to play more influential roles in determining pubertal development.

Objective To investigate associations between postpartum depression in fathers and children’s behaviors at age 5 in a national high-risk U.S. sample. Study design A secondary data analysis of 1,796 children in a national birth cohort study that oversampled non-marital births was conducted. Paternal depression was assessed 1 year after the child was born and children’s behaviors were assessed by their primary caregivers when the children were 5 years old. Unadjusted and adjusted negative binomial regression models of associations between paternal depression and child behavior scores and logistic regression models of associations between paternal depression and high scores (at least 1.5 or 2.0 standard deviations above the mean) were estimated. Results In negative binomial regression models that adjusted for child, paternal, and family characteristics and maternal depression, paternal depression was associated with a 17% higher total externalizing behavior score (Incidence Rate Ratio (IRR): 1.17; 95% Confidence Interval (CI): 1.07–1.27), a 17% higher aggressive subscale score (IRR: 1.17; 95% CI: 1.08–1.27), and an 18% higher delinquent subscale score (IRR: 1.18; 95% CI: 1.03–1.35). In adjusted logistic regression models for scores ≥2.0 standard deviations above the mean, paternal depression was associated with high total externalizing scores (e.g., Odds Ratio (OR): 3.09; 95% CI: 1.77–5.41), high aggressive behavior scores (OR: 2.40; 95% CI: 1.30–4.43), and high delinquent behavior scores (OR: 2.08; 95% CI: 1.01–4.27). There were suggestive but non-robust associations between paternal depression and attention problems and no associations between paternal depression and internalizing behaviors or social problems. Conclusion Fathers’ depression at age 1 was associated with children’s externalizing behaviors at age 5, an important developmental stage when children transition to school. These findings suggest a need to identify and support fathers with depressive symptoms to promote optimal child development.

This study investigated associations between chronic developmental/behavioral and physical health conditions and social connectedness of adolescents using rich population-based data from a national U.S. birth cohort study. Potentially disabling health conditions were reported by caregivers and categorized by our team as developmental/behavioral or physical. Social connectedness was assessed using a validated scale that measured adolescents’ reports of positive social connectedness across relevant contexts (family, friends, school). Of the 3,207 adolescents included, over one third had at least one chronic health condition. Unadjusted and adjusted linear and logistic regression models of associations between the presence of chronic health conditions (any developmental/behavioral health condition and any physical health condition, compared to no conditions) and adolescents’ social connectedness outcomes were estimated. Compared to those with no chronic health conditions, adolescents with developmental/behavioral health conditions had lower odds of high positive social connectedness scores (adjusted odds ratio [AOR]: 0.80; CI [0.67, 0.94]), having friends they really care about (AOR: 0.76; CI [0.61, 0.94]), having people who care (AOR: 0.65; CI [0.50, 0.84]), and having people with whom to share good news (AOR: 0.77; CI [0.63, 0.94]). Adolescents with chronic physical health conditions had lower odds of reporting having people who care about them (AOR: 0.72; CI [0.55, 0.94]). The findings point to the need for interventions designed to foster the development of positive interpersonal relationships, reduce loneliness, and increase positive social identity among adolescents with chronic health conditions, particularly those with developmental/behavioral health conditions.

This study investigates the effects of welfare reform—a major policy shift in the United States that increased low-income mothers' employment and reliance on earnings instead of cash assistance—on the quality of the home environments mothers provide for their preschool-age children. Using empirical methods designed to identify plausibly causal effects, we estimate the effects of welfare reform on validated survey and observational measures of maternal behaviors that support children's cognitive skills and emotional adjustment and the material goods that parents purchase to stimulate their children's skill development. The results suggest that welfare reform did not affect the amount of time and material resources mothers devoted to cognitively stimulating activities with their young children. However, it significantly decreased emotional support provision scores, by approximately 0.3–0.4 standard deviations. The effects appear to be stronger for mothers with lower human capital. The findings provide evidence that welfare reform came at a cost to children in the form of lower quality parenting. They also underscore the importance of considering quality, and not just quantity, in assessing the effects of maternal work-incentive policies on parenting and children's home environments.
