The Roles of Alcohol Availability, Overserving, and Enforcement in Recreational and Social Settings on Alcohol Misuse and Harms: A Comparison of Australia and the United States.

To examine how alcohol availability, overserving, and enforcement in recreational and social settings are related to alcohol misuse and alcohol-impaired driving among young adults in Victoria, Australia and Washington State, United States. Longitudinal data came from 1,430 participants in Victoria (n = 757; 52% female) and Washington (n = 673; 53% female), surveyed in 2014 (age 25) and 2018 (age 29) from the International Youth Development Study, a population-based, cross-national study to examine factors influencing substance use. Path modeling tested associations between age 25 perceptions of the alcohol environment, age 25 social alcohol consumption, and age 31 alcohol-related harms. Multiple-group modeling examined differences in parameter estimates across both states. Age 25 perceptions of the alcohol environment (alcohol availability, overservice in evening social venues, legal enforcement) and alcohol consumption in evening social settings were similar between the two states. Higher alcohol availability and perceived tendency of evening social venues to overserve were associated with higher alcohol consumption in these contexts. In turn, higher alcohol consumption in these settings was associated with more problematic alcohol use and an increased likelihood of alcohol-impaired driving 4 years later. Perceived likelihood of legal enforcement in evening social settings was not related to alcohol consumption in these contexts. The recreational and social settings commonly frequented by young adults can influence drinking behaviors and alcohol-related harms. Reducing alcohol availability and over-servicing in settings where young adults often congregate and socialize could reduce problematic alcohol use and alcohol-impaired driving.

The longitudinal association of cumulative depression with cannabis use disorder among young adults.

This study examined whether the cumulative experience of elevated depressive symptoms from age 19 to 23 was associated with cannabis use disorder (CUD) at age 26, and whether the association varied by perceived ease of access to cannabis and perceived risk for harms from cannabis use. Data were from 4407 young adults participating in the Community Youth Development Study. Cumulative experience of elevated depressive symptoms was calculated by summing the number of times a participant scored 10+ on the 9-item Patient Health Questionnaire across three biennial survey waves (age 19 to 23). To assess CUD, the Diagnostic Interview Schedule was used. Participants also self-reported their ease of access to cannabis and the perceived harm of regular cannabis use at the age 19, 21, and 23 waves. Marginal structural modeling was used to account for multiple time-varying and time-fixed covariates through use of inverse probability weights. In final weighted models, a greater number of time points (i.e., study waves) showing elevated depressive symptoms was associated with an increased likelihood of CUD at age 26 (Prevalence Ratio = 1.46; 95% CI: 1.20, 1.77). There was no strong evidence for moderation of this association by perceived ease of access or perceived risk for harms due to regular cannabis use. Persistent experience of elevated depressive symptoms may place young adults at risk for cannabis use disorder. Strategies to reduce the burden of depressive symptoms among young adults may lead to downstream effects such as reducing the prevalence of cannabis-related problems.

Continuity and Change in Substance Use Patterns During the Transition from Adolescence to Young Adulthood: Examining Changes in Social Roles

AbstractThis study offers a model for using multidimensional growth mixture models to identify polysubstance use trajectories by examining transitions among conjoint substance use trajectories from adolescence to young adulthood and exploring potential moderators that may facilitate transitions towards healthier substance use trajectories in young adulthood. Longitudinal mixture modeling was used to examine six waves of data collected during adolescence (ages 13, 14, 15) and young adulthood (ages 25, 29, 31) in Seattle, Washington. Data were drawn from the International Youth Development Study, a longitudinal, cross-national study examining the life course patterns of substance use and development among youth. Participants (N = 961) completed questionnaires on six occasions that assessed demographics (sex, race, highest parent education), suspension and expulsion, individual substance use, partner substance use, and social role transitions (education, marriage, childbearing, employment). Four substance use classes were identified in adolescence and included low use (n = 572, 59.6%), alcohol dominant (n = 177, 18.4%), increasing use (n = 103, 10.7%), and poly-use (n = 109, 11.3%). Five substance use classes were identified in young adulthood and included low use (n = 134, 15.3%), alcohol only (n = 349, 39.8%), alcohol and tobacco (n = 97, 11.0%), alcohol and cannabis (n = 162, 18.5%), and poly-use (n = 135, 15.4%). The transition from adolescence to young adulthood showed the strongest continuity in the poly-use class and the weakest in the low use class, with a general trend toward adding substances rather than reducing them. College graduation moderated the transition in substance use patterns from adolescence to young adulthood for low use and alcohol dominant adolescent classes but not for the poly-use class. Delays in adult role assumptions were not consistently associated with substance use classes during this transition. However, where significant, delayed marriage and parenthood acted as protective factors against the progression of substance use leading into young adulthood. The findings underscore the need for early detection and tailored prevention efforts among adolescents. By identifying pivotal periods and specific substance use patterns, these findings inform the timing and focus of targeted interventions designed to reduce the escalation of substance use leading into young adulthood.

Using moderated nonlinear factor models to adjust for differential item functioning in the Student-Teacher Relationship Scale from kindergarten to Grade 6

Prior research has demonstrated that children form developmentally salient relationships with teachers and that these relationships are uniquely predictive of subsequent functioning both in and outside of school. However, prior work estimating trajectories and predictors of teacher-student relationship quality has failed to test and adjust for bias in questionnaire items. The present study used longitudinal data from the NICHD Study of Early Child Care and Youth Development (SECCYD; N = 1140) to test and adjust for measurement bias in the Student-Teacher Relationship Scale (STRS; Pianta, 2001) across grades (K–6) and sociodemographic characteristics (i.e., birth sex, race/ethnicity, family income-to-needs ratio, and maternal education) to generate less biased estimates of trajectories of teacher-student relationship quality. Results identified differential item functioning for three of seven STRS items assessing conflict and three of eight STRS items assessing closeness, with items functioning differentially across child grade, birth sex, race/ethnicity, and maternal education level. Comparisons of growth models using non-adjusted and adjusted STRS scores highlight substantive differences between scoring approaches, such that the effects of race/ethnicity, maternal education, and maternal sensitivity on teacher-student relationship quality were masked prior to adjusting for item bias. These findings demonstrate the importance of testing and correcting for item bias in questionnaire-based assessments of teacher-student relationship quality to ensure valid conclusions.

Transactional Linkages Between Parenting Behaviors and Child Executive Functions and Self-Regulation from Early Childhood to Adolescence.

Research on the development of executive functions (EFs) and self-regulation (SR) has focused heavily on the early childhood years, when these abilities first emerge. Less is known in comparison about how these abilities develop through adolescence, and how contextual factors, such as parenting, influence their development in later years. Using longitudinal data from the Study of Early Child Care and Youth Development (SECCYD), we used random intercept cross-lagged panel modeling (RI-CLPM) to examine the bidirectional linkages between three parenting behaviors (i.e., autonomy support, supportive presence, hostility), child EFs (i.e., working memory, inhibitory control) and child SR outcomes, from early childhood to adolescence. Parenting in early childhood was significantly associated with change in child EFs from early to middle childhood, but not from middle childhood to adolescence. Specifically, greater autonomy support in early childhood was associated with stronger child working memory and inhibitory control in middle childhood; greater supportive presence in early childhood was associated with stronger child working memory in middle childhood; and higher rates of hostility in early childhood were associated with weaker child inhibitory skills in middle childhood. Reciprocal effects of child EF and SR on parenting were also observed. Specifically, stronger child inhibitory control in early childhood was associated with less hostility in middle childhood, and stronger child self-regulation in middle childhood was associated with greater supportive presence in adolescence. Accounting for lagged and stability effects, there was significant residual covariance between parenting behaviors and child SR in adolescence, suggesting that parenting continues to be associated with the development of SR skills through adolescence. Understanding reciprocal linkages between parenting and child EF/SR through adolescence is critical in developing targeted parenting interventions beyond early childhood to improve children's outcomes.

Which aspects of education are health protective? a life course examination of early education and adulthood cardiometabolic health in the 30-year study of early child care and Youth Development (SECCYD)

BackgroundPast research describes robust associations between education and health, yet findings have generally been limited to the examination of education as the number of years of education or educational attainment. Little is known about the specific features or processes underpinning education that are health protective. The objective of the current study was to address this gap by examining specific aspects of early education pertaining to student characteristics and experiences, as well as features of the classroom environment, in predicting cardiometabolic health in adulthood.MethodsSubjects were 1364 participants in the NICHD Study of Early Child Care and Youth Development (SECCYD, 1991–2009) and recent SECCYD 30-year follow-up, the Study of Health in Early and Adult Life (SHINE, 2018–2022). Models examined individual education indicators (student social skills, student-teacher relationship quality, and classroom emotional and instructional quality in the period of elementary school and student academic performance between ages 54 months and 15 years) in relation to a composite of cardiometabolic risk in adulthood (ages 26–31), reflecting central adiposity, blood pressure, insulin resistance, inflammation, and dyslipidemia. Models were adjusted for key explanatory factors including socio-demographics, infant characteristics, parental socioeconomic status (SES), and child health status. Follow-up analyses were performed to test potential mediators of early education effects on adult health, including adult SES (educational attainment, household income) and health behaviors (diet quality, activity level, sleep duration, smoking).ResultsIn adjusted models, results showed greater student social skills, indexed by a mean of annual teacher ratings between kindergarten and 6th grade, predicted lower cardiometabolic risk in adulthood (β=-0.009, p <.05). In follow-up analyses, results showed the protective effect of student social skills on cardiometabolic risk may be mediated by adult income (β=-0.0014, p <.05) and diet quality (β=-0.0031, p <.05). Effects of the other early education indicators were non-significant (ps > 0.05).ConclusionsFindings point to the potential significance of early student social competence as a link to long-term health, possibly via the acquisition of resources needed for the maintenance of health, as well as through engagement in health behaviors supporting healthy eating. However, more research is needed to replicate these findings and to elaborate on the role of early student social competence and the pathways explaining its effects on cardiometabolic health in adulthood.

Psychosocial Adjustment as a Mediator in the Relationship between Childhood Exposure to Maternal Depression and Subsequent BMI and Overweight Risk.

This study investigated the correlation between early exposure to maternal depression (from 1 month to Grade 3) and the body mass index (BMI) and potential for overweight in adolescents at age 15. It further examined if the pathway of this correlation was influenced by psychosocial adjustment during mid-childhood (Grade 3 to Grade 6), specifically through internalizing and externalizing behaviors. Our study utilized data from 844 participants in the NICHD Study of Early Child Care and Youth Development (SECCYD) to assess the effects of maternal depression, observed from when the children were one month old to Grade 3, on BMI and the likelihood of overweight or obesity in adolescents aged 15. We also explored whether the average scores of internalizing and externalizing behaviors between Grades 3 and 6 mediated the impact of early maternal depressive symptoms on subsequent health outcomes. The analysis was adjusted for demographic and socioeconomic factors. Findings revealed that internalizing and externalizing behavioral issues significantly mediated the relationship between prolonged maternal depression exposure and subsequent BMI, as well as the risk of overweight or obesity, in adolescents at age 15. Notably, this mediating effect was predominantly evident in girls. Our research demonstrated that the correlation between prolonged exposure to maternal depressive symptoms in childhood and increased BMI and overweight risk in adolescence was significantly mediated through psychosocial adjustment behaviors. We advocate for further exploration of additional mediating factors in future studies.

Pubertal timing: A life course pathway linking early life risk to adulthood cardiometabolic health.

To evaluate a series of prospective life course models testing whether the timing of pubertal development is a pathway through which prepubertal risk factors may influence adulthood cardiometabolic health. Subjects were 655 female participants in the NICHD Study of Early Child Care and Youth Development (SECCYD) and recent SECCYD 30-year follow-up, the Study of Health in Early and Adult Life (SHINE). Prepubertal risk factors included maternal menarcheal age, child race/ethnicity, child health status indicators, and child adversity indicators. Pubertal timing was indexed by breast development onset (Tanner stage [TS] II), pubic hair onset (TS II) and menarcheal age. Adulthood cardiometabolic risk (CMR) was indexed by a composite of waist circumference, systolic blood pressure, diastolic blood pressure, hemoglobin A1c, C-reactive protein, and high-density lipoprotein. Inspection of paths between the prepubertal risk factors, pubertal timing indicators, and adulthood CMR composite showed later breast development onset (-0.173, p < .01), later pubic hair onset (-0.182, p < .01), and later menarche (-0.145, p < .01) each predicted lower adulthood CMR, and each pubertal timing indicator mediated effects of prepubertal risk factors on adulthood CMR. Specifically, the timing of breast development onset and menarche mediated effects of maternal menarcheal age, Black (vs. White), Asian/PI (vs. White), child BMI percentile, and child SES on adulthood CMR (all ps < .05), and the timing of pubic hair onset mediated effects of maternal menarcheal age, Black (vs. White), and child BMI percentile on adulthood CMR (all ps < .10). Findings in the current study contribute to the broader literature by identifying pubertal development and its timing as a potentially important pathway through which early life exposures may shape adulthood cardiometabolic health and disease. These findings have important implications for novel opportunities for increased surveillance and potential intervention focusing on pubertal development as a target to improve health more broadly.

The role of adolescent social inclusion in educational attainment among vulnerable youth.

Completing high school enables access to educational and employment opportunities associated with better physical and mental health and improved quality of life. Identifying modifiable factors that promote optimal educational trajectories for youth experiencing disadvantage is an important research focus. Social inclusion has been theorised to play a role in promoting better educational outcomes for this priority population, however limited research has examined this relationship. This study used three waves of data from the state-representative Australian arm of the International Youth Development Study (IYDS) (youngest cohort, N = 733; 54% female, 95% Australian born) to examine the extent to which vulnerability in primary school (Grade 5; Mage = 10.97, SD = 0.38) and social inclusion in mid-adolescence (Year 10; Mage = 15.50, SD = 0.53), were associated with school completion in young adulthood (post-secondary; Mage = 19.02, SD = 0.43). Regression models identified an interaction between social inclusion and vulnerability (OR = 1.37, 95% CI [1.06, 1.77], p = .016), indicating that the association between vulnerability and school completion varied as a student's level of social inclusion increased. Higher social inclusion was beneficial for youth with lower levels of vulnerability but did not appear to influence school completion for the most vulnerable students. For many young people, promoting social inclusion may support engagement in education and play a protective role. However, further research is needed to better understand the role of social inclusion for highly vulnerable youth, particularly the mechanisms via which social inclusion may have differential effects on school completion.

The mediating role of child delay of gratification in the link between early and prolonged poverty exposure and adolescent allostatic load

Early and prolonged exposure to poverty disrupts biological processes associated with the body’s stress response system, leading to long-term negative health outcomes, including obesity, autoimmune disorders, and cardiovascular disease. Allostatic load (AL), a composite measure of chronic stress on the body, is a robust predictor of subsequent health outcomes. However, developmental research examining the associations of early poverty exposure with AL in adolescence, as well as the underlying mechanisms of influence is limited. Early poverty exposure also impedes healthy development of child self-regulation, which may increase risk for high AL in adolescence, but this mechanistic pathway has not yet been tested. We used data from the national Study of Early Child Care and Youth Development (SECCYD) to examine the longitudinal associations between prolonged poverty exposure in early childhood (0–3 years) and AL in adolescence (age 15). We also tested the mediating role of child delay of gratification, a behavioral measure of self-regulation (at age 54 months), in the potential association between early poverty exposure and adolescent AL. Accounting for model covariates (i.e., child biological sex and race-ethnicity) and individual differences in child delay of gratification, early and prolonged poverty exposure was significantly associated with higher AL at age 15. The indirect effect through child delay of gratification was not significant, but the individual pathways of the indirect effect were significant, and the overall direct association of early poverty exposure with adolescent AL was significant. Our findings show that prolonged exposure to poverty in early childhood (0–3 years) can have significant negative associations with both child delay of gratification (at 54 months) and AL (at age 15). Given that the detrimental impacts of poverty exposure can be detected at an early age, targeted prevention efforts (e.g., anti-poverty programs such as cash assistance programs) may be able to offset some of the risks of early poverty exposure on self-regulation and AL.

Early Parenting Precursors of Child Developmental Outcomes: What Counts Beyond Parental Sensitivity?

SYNOPSIS Objective. Parental sensitivity is a precursor of child developmental outcomes, but other parental behaviors such as warmth, stimulation of cognitive development, intrusiveness, and hostility are also associated with those outcomes. The aim of the current study was to untangle unique linkages among parental sensitivity, other parental behaviors, and outcome domains deemed relevant for child welfare in an ethnically homogenous sample. Design. Data from European American dyads of the NICHD Study of Early Child Care and Youth Development (N = 1,097) across 13 waves from 6 months to 15 years of age were split into two datasets for cross validation. Twelve of 284 outcome measures were selected a priori as domain indicators. Only one measure was eligible for the domain Coping, therefore this measure and domain were omitted. Results. Confirmatory factor analysis revealed acceptable model fit for robust outcome domains of Emotional Regulation Problems, Self-Concept, and Problem Behavior assessed during childhood and adolescence. Using structural equation modeling, parental sensitivity statistically predicted Emotional Regulation Problems during primary school and Problem Behavior throughout primary school and adolescence. However, prediction in adolescence was no longer statistically significant after adding demographic confounders. Stimulation of cognitive development predicted Problem Behavior during primary school over and above parental sensitivity, yet, this effect was no longer statistically significant after adding demographic confounders. Parental intrusiveness and detachment, positive and negative regard, and flatness of affect showed no added predictive value. Conclusions. These findings may guide parsimonious assessment of the quality of the caregiving environment of young children.

Longitudinal associations between adult-supervised drinking during adolescence and alcohol misuse from ages 25–31 years: A comparison of Australia and the United States

Prior studies suggest that adult supervised drinking in adolescence predicts greater adolescent alcohol misuse. Long-term follow up data examining how adult supervised drinking during adolescence relates to alcohol misuse in adulthood are lacking. Longitudinal data from the International Youth Development Study tested associations between adult supervised drinking during adolescence (ages 13–16; 2002–2004) and adult alcohol misuse (ages 25–31; 2014, 2018, 2020). Cross-nationally matched samples were compared in Washington State, USA (n = 961) and Victoria, Australia (n = 1,957; total N = 2,918, 55 % female, 83 % White), where adult-supervised adolescent alcohol use was more common. Multilevel analyses adjusted for state, sex, adolescent drinking, parent education, family management, family history of substance use problems, and parent alcohol-related norms. Adult supervised drinking in adolescence (at dinner or parties, on holidays) predicted more adult alcohol misuse (mean Alcohol Use Disorders Identification Test score; b[SE] 0.07[0.03]; p = 0.004) and higher rates of alcohol-impaired driving (Odds Ratio [OR] 1.501, p = 0.034) and riding with an alcohol-impaired driver (OR 1.669, p = 0.005), but not the use of strategies to moderate alcohol intake (e.g., counting drinks). Better family management (monitoring, clear rules) in adolescence predicted less adult alcohol misuse. Associations were similar in the two states. Reducing the frequency of adult supervised drinking and improving family management practices in adolescence may help to decrease alcohol misuse well into adulthood. Findings support the widespread implementation of substance use prevention and family management training programs.

Taking the long view of adolescent work quality.

Following Schulenberg's research on teenage employment and vocational development, we ask to what extent do job dimensions reflecting the quality of work experience during mid-adolescence (e.g., work stress, autonomy, learning and advancement opportunities, hourly pay, wage satisfaction, and work hours) predict the same work experiences during the ensuing occupational career? Using longitudinal data from the Youth Development Study (N = 711 individuals over 3164 occasions), and hybrid panel models to control for unobserved time-stable selection influences, we find a high level of continuity of work quality from adolescence to mid-life. Multiple dimensions of adolescent work quality are associated with the same dimensions of work quality in adulthood, even after controlling for educational attainment and other time-varying adult confounders.

Revisiting implications of early family economic conditions for adolescent adaptations: An integrative cascade model.

Implications of family economic conditions (FECs) for child development have been extensively examined. What remains sparse is research spanning multiple life stages to delineate the far-reaching influences of early FECs for child subsequent development in different domains and how various family stress and investment processes jointly account for such association. To address these gaps, using data from 929 families in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (NICHD Early Child Care Research Network, 2001, 2005), this study examined how family income-to-needs ratio (FITNR) when children were 1-36 months old was associated with child language skills, social competence, externalizing, and internalizing problems at 6th grade. Parental investment and maternal/paternal depressive symptoms and sensitivity when children were 54 months old and in 3rd grade were tested as potential mediators. Results indicated that early FITNR shaped child cognitive, social, and behavioral adaptation in early adolescence indirectly through parental investment, depressive symptoms, and sensitive parenting in the preschool period and middle childhood. Parental investment, depressive symptoms, and sensitive parenting played such mediating roles above and beyond each other. Parental investment primarily accounted for the association between early FITNR and child later language skills, whereas parental depressive symptoms and sensitive parenting uniquely explained the associations between early FITNR and child subsequent internalizing symptoms, externalizing problems, social competence, and language skills. Theoretical/practical implications of such findings were discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Understanding puberty and its measurement: Ideas for a maturing field

Puberty is a complex developmental process involving neuroendocrine changes (e.g., hormones, brain development), physical maturity (e.g., breast development, facial hair growth), and social reorganization (e.g., new social roles and relationships). Despite robust literature on the psychological correlates of pubertal development, research is limited by (1) a narrow conceptualization of puberty, (2) a focus on single pubertal markers (e.g., onset), and (3) invasive clinical exams that may limit access to representative samples. Indeed, many aspects of pubertal development - when it begins, how quickly or slowly youth progress through puberty, and how one’s maturity is viewed by others - are central to young people’s development and their future health and wellbeing. Further, while pubertal measures can reflect many different aspects of puberty, each telling a distinct story about development, they are frequently used and understood in similar ways, often privileging the experiences of White youth (and especially, girls) over those with marginalized social identities.The goals of this symposium are to bring together three researchers who will discuss the conceptualization and measurement of puberty as well as the implications of different measurement approaches for understanding youth’s current and future health and wellbeing. In the first presentation, Niamh MacSweeney will present data from the Adolescent Brain Cognitive Development (ABCD) Study demonstrating the sex-specific association of adrenal and gonadal pubertal timing with brain development and subsequently, depression over four years. In the second presentation, Natasha Chaku will use data from the Study of Early Childcare and Youth Development (SECCYD) to explore how different measures (i.e., Tanner stages vs. parent reports) and analytic approaches (i.e., latent growth curves vs. sex and age-related residuals) for understanding pubertal timing can impact inferences related to adolescent mental health. In the final presentation, Anne-Lise Goddings will review the state of current pubertal assessment measures, discussing limitations identified from youth, clinicians, and researchers and the development of a novel digital tool, co-developed with young people. The discussant, Lindsay Till Hoyt, will integrate the findings, highlighting the importance of considering the accuracy and meaning of different pubertal measures and how they relate to the biopsychosocial experiences of diverse youth.

Progression of Comorbid Depression and Substance Use among Racially Diverse Adults.

Comorbidity of depression and substance abuse is common and a major public health burden. Studies of this form of comorbidity in racial and ethnic minoritized (REM) populations are minimal and have mixed findings. The present study examined the effect of general risk factors (family bonding, supervision, involvement, peer delinquency), depression risk factors (caregiver depression), and substance use risk factors (adult family members, sibling, and peer substance use) in early adolescence (~ ages 13-14) on comorbid depression and substance use in later adolescence (~ ages 15-17) and adulthood (~ ages 29-31) and continuity in comorbidity from adolescence to adulthood. Longitudinal data on 1000 Black (n = 680) Hispanic (n = 170) and White (n = 150) individuals came from the Rochester Youth Development Study. Participants were interviewed 14 times over 17 years beginning in 1988. General risk factors predicted comorbidity across racial/ethnic groups. Substance specific risk predicted comorbidity among Black and Hispanic individuals whereas depression specific risk was predictive among White individuals. Adolescent comorbidity predicted comorbidity in adulthood across race. These findings highlight the importance of substance use intervention for racial and ethnic minoritized individuals and mental health risk factors in Whites. The continuity of comorbidity from adolescence to adulthood highlights the importance of targeting adolescents for intervention to prevent long-term manifestation of this form of comorbidity and its associated consequences.

Body mass index, internalizing behavior and executive function: examining trait-state effects from age 2 to 15.

This study aimed to examine the reciprocal relation between body mass index and internalizing behavior from age 2 to 15, and also the predictive role of executive function. This study included a subset sample of 640 children (47% were male) from the National Institute of Child Health and Development Study of Early Child Care and Youth Development. A refined random-intercept cross-lagged model was employed to analyze: (1) the reciprocal relation between children's body mass index and internalizing behavior assessed in eight waves from age 2 to 15; (2) the predictive role of executive functioning in both children's body mass index and internalizing behavior. Trait-level body mass index-to-internalizing behavior association was not found; a significant state-level prediction from body mass index in 5th grade to internalizing behavior in 6th grade was found. Executive function was significantly associated with trait-level body mass index, trait-level internalizing behaviors, and state-level internalizing behaviors. The findings suggest that deficits in children's executive functioning may be a shared risk associated with both high body mass index and internalizing behaviors. From an intervention perspective, this study highlighted the importance of targeting executive function to intervene in children's obesity or internalizing behaviors.

Time-varying Correlates of Adult Singlehood: Education, Work, Living Arrangements, and Mental Health

Using the Youth Development Study (n = 504 women and 421 men), we examine how changes in education, work, living arrangements (e.g., living with children, parents, and/or roommates), and mental health predict occasions in adulthood when respondents were single (i.e., not living with a spouse or cohabiting with an unmarried partner) from ages 21 to 38. The odds of singlehood were higher when individuals were living with parents or living with roommates. The odds were lower when living with children, as well as after earning a BA/BS degree. Overall, the correlates shed light on the growing population of single US adults.

Longitudinal Links Between Parental Emotional Distress and Adolescent Delinquency: The Role of Marital Conflict and Parent-Child Conflict.

The mediating processes linking parental emotional distress and changes in adolescent delinquency over time are poorly understood. The current study examined this question using data from 457 adolescents (49.5% female; 89.5% White; assessed at ages 11, 12, and 15) and their parents, part of the national, longitudinal Study of Early Child Care and Youth Development (SECCYD). Maternal depression was only directly associated with changes in adolescent delinquency. Paternal depression was indirectly associated with changes in adolescent delinquency through a partner effect on mother-child conflict. The findings indicate the salience of parental depression and mother-child conflict for increases in adolescent delinquency and highlight the importance of including parental actor and partner effects for a more comprehensive understanding of the tested associations.

The predictive validity of the strange situation procedure: Evidence from registered analyses of two landmark longitudinal studies.

Meta-analyses demonstrate that the quality of early attachment is modestly associated with peer social competence (r = .19) and externalizing behavior (r = -.15), but weakly associated with internalizing symptoms (r = -.07) across early development (Groh et al., Child Development Perspectives, 11(1), 70-76, 2017). Nonetheless, these reviews suffer from limitations that undermine confidence in reported estimates, including evidence for publication bias and the lack of comprehensive assessments of outcome measures from longitudinal studies in the literature. Moreover, theoretical claims regarding the specificity of the predictive significance of early attachment variation for socioemotional versus academic outcomes had not been evaluated when the analyses for this report were registered (but see Dagan et al., Child Development, 1-20, 2023; Deneault et al., Developmental Review, 70, 101093, 2023). To address these limitations, we conducted a set of registered analyses to evaluate the predictive validity of infant attachment in two landmark studies of the Strange Situation: the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) and the NICHD Study of Early Child Care and Youth Development (SECCYD). Across-time composite assessments reflecting teacher report, mother report, and self-reports of each outcome measure were created. Bivariate associations between infant attachment security and socioemotional outcomes in the MLSRA were comparable to, or slightly weaker than, those reported in the recent meta-analyses, whereas those in the SECCYD were weaker for these outcomes. Controlling for four demographic covariates, partial correlation coefficients between infant attachment and all socioemotional outcomes were r ≤ .10 to .15 in both samples. Compositing Strange Situations at ages 12 and 18 months did not substantively alter the predictive validity of the measure in the MLSRA, though a composite measure of three different early attachment measures in the SECCYD did increase predictive validity coefficients. Associations between infant attachment security and academic skills were unexpectedly comparable to (SECCYD) or larger than (MLSRA) those observed with respect to socioemotional outcomes.
