The aims of the current 30 year prospective study were to determine: (1) whether socially withdrawn kindergarten children are less likely than others to enter serious romantic relationships or become parents by age 34, (2) whether socially withdrawn children parent differently than non-withdrawn individuals when they grow up, and (3) whether subtypes of withdrawal are associated with different adult outcomes. Following Harrist et al. (1997), 558 kindergarten children (81% White, 17% Black) were categorized into one of the five groups: four clusters of social withdrawal ( n = 95 unsociable, 23 passive-anxious, 18 active-isolate, and 25 sad/depressed) or non-withdrawal ( n = 397), using directly observed school behavior and teacher ratings. About 30 years later ( M age = 34.45 years, SD = 0.62 years), participants self-reported on their romantic relationship and parent status and parenting warmth and harshness. Overall, the group of socially withdrawn children was no more or less likely than the non-withdrawn group to be in a current relationship or a parent, nor did they report any differences in parenting. However, the active-isolate subtype of social withdrawal, characterized by impulsivity and anger, was less likely than the non-withdrawn group to be in a current relationship ( B = −1.24, p < 0.05). This study suggests socially withdrawn children in the United States fare similarly to non-withdrawn peers in adulthood in their romantic relationships and parenting, but a subgroup of active-isolate children may be at risk of not entering adult relationships.

Early interventions are a preferred method for addressing behavioral problems in high-risk children, but often have only modest effects. Identifying sources of variation in intervention effects can suggest means to improve efficiency. One potential source of such variation is the genome. We conducted a genetic analysis of the Fast Track ran-domized control trial, a 10-year-long intervention to prevent high-risk kindergarteners from developing adult externalizing problems including substance abuse and antisocial behavior. We tested whether variants of the glucocorticoid receptor gene NR3C1 were associated with differences in response to the Fast Track intervention. We found that in European-American children, a variant of NR3C1 identified by the single-nucleotide polymorphism rs10482672 was associated with increased risk for external-izing psychopathology in control group children and decreased risk for externalizing psychopathology in intervention group children. Variation in NR3C1 measured in this study was not associated with differential intervention response in African-American children. We discuss implications for efforts to prevent externalizing problems in high-risk children and for public policy in the genomic era.

The present study investigated matches and mismatches between adolescent and parent socialization domains (i.e., protection, guidance) as related to adolescent reception of parental support during a laboratory-based social evaluation challenge. Participants were 80 early adolescents (Mage = 12.36 years, SD = 1.33, 55% males, 55% Black, 42.5% White, and 2.5% other races or ethnicities) and one parent or guardian per adolescent. Observational measures of parent socialization domains assessed sensitivity to adolescents’ thoughts and feelings (protection domain) and prosocial behavioral advice (guidance domain). Measures of parallel adolescent socialization domains included self-reported discomfort during a social evaluation challenge (protection domain) and desire to continue the social evaluation challenge (guidance domain). Adolescent reception of parental support was assessed using an observational measure of adolescent attentiveness and responsiveness to the parent during a parent–adolescent discussion about how to approach the social evaluation challenge. Analyses of interactions between measures of parent and adolescent socialization domains revealed: (a) higher levels of adolescent-reported discomfort during the social evaluation challenge interfered with their reception of parental prosocial behavioral advice but did not enhance their reception of parental sensitivity, and (b) higher levels of adolescent-reported desire to continue the social evaluation challenge interfered with their reception of parental sensitivity but did not enhance their reception of parental prosocial behavioral advice. This study advances socialization research by identifying conditions under which adolescents are more and less receptive to supportive communication from parents.

Background Across several sites in the United States, we examined whether kindergarten conduct problems among mostly population‐representative samples of children were associated with increased criminal and related (criminal + lost offender productivity + victim; described as criminal + victim hereafter) costs across adolescence and adulthood, as well as government and medical services costs in adulthood. Methods Participants (N = 1,339) were from two multisite longitudinal studies: Fast Track (n = 754) and the Child Development Project (n = 585). Parents and teachers reported on kindergarten conduct problems, administrative and national database records yielded indexes of criminal offending, and participants self‐reported their government and medical service use. Outcomes were assigned costs, and significant associations were adjusted for inflation to determine USD 2020 costs. Results A 1SD increase in kindergarten conduct problems was associated with a $21,934 increase in adolescent criminal + victim costs, a$63,998 increase in adult criminal + victim costs, a $12,753 increase in medical services costs, and a$146,279 increase in total costs. In the male sample, a 1SD increase in kindergarten conduct problems was associated with a $28,530 increase in adolescent criminal + victim costs, a$58,872 increase in adult criminal + victim costs, and a $144,140 increase in total costs. In the female sample, a 1SD increase in kindergarten conduct problems was associated with a$15,481 increase in adolescent criminal + victim costs, a $62,916 increase in adult criminal + victim costs, a$24,105 increase in medical services costs, and a $144,823 increase in total costs. Conclusions This investigation provides evidence of the long‐term costs associated with early‐starting conduct problems, which is important information that can be used by policymakers to support research and programs investing in a strong start for children.

Effective parental responses to peer victimization may hinge on parental awareness of youths’ peer victimization experiences, yet predictors of parental awareness are understudied. We investigated the extent of parent–adolescent agreement about early adolescents’ peer victimization experiences as well as predictors of parent–adolescent agreement. Participants included a diverse community sample of early adolescents (N = 80; Mage = 12.36 years, SD = 1.33; 55% Black, 42.5% White, 2.5% other race/ethnicity) and their parents. Observer-rated parental sensitivity and adolescent-reported parental warmth were examined as predictors of parent–adolescent agreement about peer victimization. Following contemporary analytic procedures for examining informant agreement and discrepancies, polynomial regression analyses revealed that parental sensitivity moderated the association between parent and early adolescent reports of peer victimization, such that the association between parent and early adolescent reports of peer victimization was stronger at higher levels of parental sensitivity than lower levels of parental sensitivity. These results provide insight into how to enhance parental awareness of peer victimization.

Applying both latent variable and network frameworks, we conducted a comprehensive psychometric evaluation of the diverse array of symptoms from three externalizing dimensions, including attention problems, aggressive behavior, and delinquency/rule-breaking of the Child Behavior Checklist (Achenbach, 1991) across six time points from childhood to early adolescence. We also examined sex differences. Participants (N = 1,339) were drawn from two multisite longitudinal studies: Fast Track and the Child Development Project. Parents reported on externalizing psychopathology in kindergarten and Grades 1, 2, 4, 5, and 7. Using exploratory structural equation modeling, we found almost uniformly excellent fit across time and samples. However, we also observed multiple cross-loadings and heterogeneity in terms of which symptoms cross-loaded across time points. Alternatively, using network modeling, we observed that symptoms of attention problems and aggressive behavior had stronger connections, relative to delinquency/rule-breaking, across time and samples. Significant differences in overall connectivity were found at early (kindergarten vs. Grade 1, Grade 1 vs. Grade 2) and late (Grade 5 vs. Grade 7) time points for the combined sample and only late time points for the male sample. In addition, the items impulsive and lies or cheats consistently displayed the greatest bridge strength, that is, symptom from one dimension that connects to symptoms from another dimension, across time and samples. Our results illustrate how two methods-latent variable and network modeling-provide important and complementary information on multidimensional constructs. Findings also inform understanding of externalizing psychopathology through childhood to early adolescence by identifying key symptoms, critical transition points, and possible transdiagnostic liabilities.

This study examined whether a key set of adolescent and early adulthood risk factors predicts problematic alcohol, cannabis, and other substance use in established adulthood. Two independent samples from the Child Development Project (CDP; n = 585; 48% girls; 81% White, 17% Black, 2% other race/ethnicity) and Fast Track (FT; n = 463; 45% girls; 52% White, 43% Black, 5% other race/ethnicity) were recruited in childhood and followed through age 34 (CDP) or 32 (FT). Predictors of substance use were assessed in adolescence based on adolescent and parent reports and in early adulthood based on adult self-reports. Adults reported their own problematic substance use in established adulthood. In both samples, more risk factors from adolescence and early adulthood predicted problematic alcohol use in established adulthood (compared to problematic cannabis use and other substance use). Externalizing behaviors and prior substance use in early adulthood were consistent predictors of problematic alcohol and cannabis misuse in established adulthood across samples; other predictors were specific to the sample and type of substance misuse. Prevention efforts might benefit from tailoring to address risk factors for specific substances, but prioritizing prevention of externalizing behaviors holds promise for preventing both alcohol and cannabis misuse in established adulthood.
