Youth involved in the juvenile legal system face elevated rates of internalizing and externalizing behavioral health problems, including distress, substance use, and antisocial behavior. However, research rarely examines how these problems co-develop and relate to long-term legal outcomes. This study applied group-based multi-trajectory modeling to longitudinal data from 1,216 system-involved male youth (Mage = 15.29; 46% Latino/Hispanic, 37% Black, 15% White, 2% multiracial/other) to uncover patterns of co-occurring externalizing (antisocial behavior, harmful substance use, antagonistic traits) and internalizing (distress) problems and their association with rearrest in young adulthood. We identified eight unique trajectory groups, three of which showed elevated rearrest risk: (1) youth with moderate externalizing and internalizing problems that worsened over time, (2) youth with high-decreasing externalizing problems but moderate-increasing internalizing problems, and (3) youth with high-stable antagonistic traits in the absence of other elevated problems. Membership in these high-risk groups was predicted by specific contextual factors – including peer deviance, violence exposure, negative home environment, and low school orientation – highlighting the role of both risk and protective influences. These findings underscore the utility of longitudinal, dimensional behavioral health assessment in identifying long-term system-involvement risk and tailoring intervention strategies for system-involved youth.

Temperament has been linked to the development of externalizing symptoms, but the nature of these associations remains unclear. Traditional approaches often treat early reactive temperament as static, overlooking developmental variation. This study applied a longitudinal latent change score model to examine how levels and changes in Negative Affect (NA) and Surgency from age 3 to 5 predict Conduct Problems (CP) and Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in early childhood. Data from the National Educational Panel Study (N = 2,477) were analyzed. Temperament was assessed at ages 3, 4, and 5 using the Children’s Behavior Questionnaire, and CP and ADHD symptoms were measured at ages 5, 6, and 8 with the Strengths and Difficulties Questionnaire. Measurement invariance was established. Significant individual differences in developmental change emerged. Change in NA and Surgency, but not baseline levels, predicted higher latent CP and ADHD symptom levels at age 5 and further increases through age 8. These findings indicate that intraindividual change in reactive temperament can be a relevant marker of developmental risk. Temperamental risk for externalizing symptoms in early childhood is not fixed but may be shaped by both stable dispositions and developmental change, highlighting the importance of assessing temperament development to identify early emerging risk.

The present work investigated changes in well-being during the transition out of upper secondary education (i.e., from shortly before graduating from upper secondary education to approximately one year later). The motivation for a post-school pathway (e.g., starting university or vocational training) was examined as a potential predictor of between-person differences in well-being trajectories. German-speaking high school graduates (N = 874 between ages 16 and 20; 69% female, 95% born in Germany) reported on their affective well-being in up to four surveys and indicated their motivation for their post-school pathway. At three measurement occasions, participants also participated in a three-week experience sampling phase, in which they reported on their daily well-being. Latent change models revealed an initial increase in well-being after graduation, but mixed evidence for subsequent trajectories, as both positive and negative affect decreased on average. Changes in well-being were more pronounced for global than for daily assessments of affective well-being. We did not find associations between the motivation for a post-school pathway and well-being trajectories. Overall, these findings highlight the complexity of well-being trajectories during the transition out of upper secondary education and the importance of using multiple time points and assessment methods to understand these dynamics.

In a sample of early post-menarchal female adolescents, this study examined sleep regularity in relation to depression symptoms, circadian rhythms, and chronotype preference. Sixty-six female adolescents, aged 11–14 and within fifteen months post-menarche, completed a one-week sleep and circadian rhythm assessment involving self-reported sleep behaviors, 24-h sleep monitoring using wrist actigraphy, and serial cortisol and 6-sulfatoxymelatonin collections for four days. Sleep regularity was operationalized as the probability of being in the same wake/sleep state at any two timepoints 24 h apart (i.e., sleep regularity index (SRI)). Reduced SRI was associated with higher depressive symptoms (F [1,273] = 18.65, p = < .0001), as were eveningness chronotype (F [1,273] = 21.13, p = < .0001), sleep duration (F [1,273] = 6.25, p = .01), and self-reported life stress (F [1,273] = 22.82, p = < .0001). The interaction between SRI and chronotype was also a predictor of increased depression (F [1,273] = 18.65, p = < .0001), such that eveningness and low sleep regularity predicted higher scores. Sleep regularity was not significantly associated with cortisol awakening response, cortisol slope, or overnight melatonin levels. Sleep regularity appears linked to altered mood in early post-menarchal girls. Further research linking sleep regularity to physiological processes governing sleep is warranted. Interventions targeting sleep regularity stand to improve mental health outcomes, as well as promote healthy developmental trajectories for affect regulation.

Adolescence represents a pivotal neurodevelopmental period marked by escalating anxiety symptoms and heightened approach motivations. Although anxiety is typically linked to avoidance, concurrent shifts in motivational systems and neurocircuitry may alter its behavioral and neural expression, shaping developmental trajectories and treatment response. This study investigated how approach motivations (Behavioral Activation System; BAS) interact with anxiety to influence behavior and brain function in N = 121 adolescents (ages 9–13; 44% girls; 33.1% White, 22.3% Latino, 19.8% Asian, 14.9% Black, 9.9% Mixed Race). Participants completed a decision-making task and resting-state fMRI. Dimensional analyses examined joint effects of anxiety and BAS on risk-taking behaviors, task-evoked neural activity and connectivity, and intrinsic connectivity at rest. Higher anxiety was associated with risk aversion and inhibition when BAS was low, but with risk-taking and impulsivity when BAS was high (risk-taking: β = 0.25, p = .012; inhibitory control: β = 0.13, p < .001). During risk-taking, anxiety and BAS showed interactive effects on striatal (β = −0.10, p = .006) and amygdala (β = 0.10, p = .005) activity alongside distinct effects on prefrontal–subcortical connectivity (β = −0.30, p = .014; β = 0.17, p = .01). Higher BAS was associated with stronger intrinsic prefrontal–striatal connectivity (β = 0.23, p = .012), while anxiety showed no significant resting-state effects. Findings underscore the role of reward-related systems in adolescent anxiety and support developmentally informed, personalized intervention strategies.

Attachment disorganization has enduring consequences for children’s socioemotional health. Although disrupted caregiving (e.g., frightening or intrusive behaviors) is a strong antecedent of attachment disorganization, much of its variance remains unexplained, highlighting the need to identify additional precursors. This longitudinal study examined the combined effects of mothers’ observed disrupted caregiving at six months of age, and their self-reported psychopathology, childhood maltreatment history, and sociodemographic risk, on infant attachment disorganization in the strange situation procedure at 22 months of age. Participants included 285 mother–infant dyads (52% boys; 80% white) from a Canadian pregnancy cohort. Sociodemographic risk (β = .15), disrupted caregiving (β = .27), and their interaction (β = .24) were associated with attachment disorganization. Sociodemographic risk was associated with greater attachment disorganization only at high levels of disrupted caregiving. Intervention strategies that address both caregiving behaviors and broader sociodemographic risks are needed to reduce attachment disorganization.

New military recruits, typically emerging adults, must rapidly adapt to the stressors of basic combat training (BCT) – a developmentally significant and intentionally stressful experience. Drawing on a developmental psychopathology framework of risk and resilience, we prospectively examined predictors of psychological adaptation in a longitudinal sample of recruits (age mean = 19.0, SD = 3.0) assessed before and after BCT (59.7% of those eligible for follow-up; N = 657). Pre-registered hierarchical linear regressions tested direct and moderating effects of individual difference variables previously linked to risk and resilience. Higher levels of prior adversity, worse self-regulatory difficulties, and (unexpectedly) higher general cognitive ability at baseline were associated with worsening post-BCT internalizing distress, after accounting for baseline symptoms. Gender, baseline social support, and baseline Multidimensional Personality Questionnaire (MPQ) scales were not associated with longitudinal changes in internalizing distress, and no moderation effects were found. Our findings suggest that bolstering emotion regulation skills, especially among those with prior adversity, may be important for preventing the emergence of psychopathology and promoting more successful adaptation to military roles. The unexpected association between cognitive ability and distress may reflect context sensitivity, suggesting that the demands of BCT may alter the typical adaptive function of cognitive strengths.

Although temperamental negative affectivity has been identified as a developmental mechanism mediating the link between perinatal risk and internalizing problems in early childhood, its role in predicting broader behavioral and emotional problems across childhood remains understudied. We examined the longitudinal relations among perinatal complications (i.e., prenatal maternal depression and cardiometabolic complications, preterm birth, and low birth weight), children’s negative affectivity (Mage = 2.76; SD = 2.32; range = 0.24–12.46 years), and children’s internalizing, externalizing, and total problems (Mage = 5.12; SD = 2.63; range = 1.50–16.85 years) in the Environmental influences on Child Health Outcomes (ECHO) program (N = 3070; 47% females). Results support child negative affectivity as a mechanism in the developmental pathway linking perinatal maternal depressive symptoms and preterm birth to future emotional and behavioral problems, underscoring the importance of early prevention and intervention efforts to promote psychological well-being of at-risk children.

Encouraging children’s sympathy (i.e., concern for others) across an array of social contexts is important for strengthening their prosocial responses to conflict and reducing aggression. We examined Canadian children’s (6, 9, and 12 years; N = 186; 50% girls and 50% boys) situational sympathetic responding following harm to victims, and how sympathy across contexts was linked to their aggressive behaviors (beyond dispositional sympathy). Children’s situational sympathy (sadness supported by moral reasoning) was measured in response to (un)provoked harm to hypothetical peers in vignettes. Parents reported on children’s proactive and reactive aggression. We also measured children’s dispositional sympathy via child- and parent-reports. Results showed that children felt stronger situational sympathy for victims of unprovoked harm than provoked harm, and only sympathy following unprovoked harm showed age-related increases. Above and beyond dispositional sympathy, lower situational sympathy in response to provoked harm was associated with higher reactive aggression. These findings demonstrate that children’s sympathy is dampened by a victim’s prior negative behavior – an emotional blunting effect that may have implications for their own retaliatory behavior.

Low socioeconomic status (SES) is linked to pubertal development, mental health issues, and academic performance. However, the role of early pubertal development in the link between low SES and mental health and academic outcomes is unclear. Using longitudinal data from the ABCD Study (9–10 years at baseline, N = 9,848, 52.2% males) across four time points, we examined associations between household and neighborhood disadvantage, pubertal development, and mental health and academic achievement. Greater household and neighborhood disadvantage were associated with more advanced pubertal status at baseline in both males and females. Among females, higher pubertal status at baseline mediated the association between lower household income and neighborhood disadvantage with greater mental health problems and poorer school performance. Additionally, slower pubertal tempo attenuated the relationship between neighborhood disadvantage and these outcomes in females. These findings underscore the importance of considering both household and neighborhood contexts in shaping adolescent development and highlight pubertal development as a potential pathway underlying socioeconomic disparities in mental health and academic achievement.

This study addressed the prevalence of resilience within specific domains (domain-specific resilience) and across multiple domains (multidomain resilience), as well as the predictive value of resilience for long-term outcomes. Using data from 244 parentally bereaved youth ages 8 – 16 who completed multiple assessments over 15 years in a randomized preventive intervention trial, we examined resilience trajectories across 10 outcomes in five domains on which bereaved youth are at risk, assessed over 14 months. Resilience was defined as low, stable problems or high, stable competencies across assessments; and multidomain resilience as the number of outcomes on which there were resilient trajectories. Results showed that resilience was generally common within specific domains, though its prevalence varied across multiple domains. Multidomain resilience followed a near-normal distribution, with few people having no domain on which they are resilient or being resilient across all domains. Several domain-specific resilience trajectories and multidomain resilience predicted multiple outcomes 15 years after baseline.

Socioeconomic disadvantage has been established as a key risk factor for adverse child behavioral outcomes. Understanding how individual components of socioeconomic status (SES) interact with each other can elucidate protective factors and inform interventions and policies to promote positive developmental outcomes. This study examined the interactive effects of prenatal household income and neighborhood deprivation on child externalizing and internalizing problems (N = 793; Mage = 8.37 years; 51.2% females; 81.5% White). Results revealed an interaction effect between prenatal household income levels and neighborhood deprivation on child externalizing problems. Higher neighborhood deprivation was associated with higher child externalizing outcomes only at lower household income levels per person. Although no interaction between household income and neighborhood deprivation on child internalizing problems was observed, lower household income levels were independently associated with higher child internalizing problems. These findings underscore how prenatal individual- and neighborhood-level SES factors interact to shape children’s behavioral outcomes across childhood.

Friends and popular peers are important sources of influence across the transition into adolescence. The present study examines the assertion that the magnitude of influence from friends and popularity-based norms varies across behavioral domains. Participants were 543 (268 girls, 275 boys) students from 29 5th–8th grade (ages 10 to 14) classrooms in three Lithuanian public middle schools. Most were ethnic Lithuanians. Self-reports of socioemotional adjustment, including emotional problems, lack of emotional clarity, problem behaviors, social media use, and weight concerns, were collected in the fall and winter of a single academic year, approximately three months apart. Popularity and academic achievement were assessed through peer nominations. Top-ranked best friends were identified from outgoing nominations. Status-based norms, calculated separately for each socioemotional adjustment variable in the fall (Time 1), represented popularity-weighted classroom averages. Results from longitudinal Group Actor-Partner Interdependence Model analyses indicated that best friends and status-based norms exerted differing amounts of influence over different behaviors. When both were included in the same model (with shared effects removed), best friends influenced emotional problems, lack of emotional clarity, and problem behaviors. Among older adolescents, best friends also influenced academic achievement. Status-based norms influenced social media use and, among older adolescents, weight concerns.

The present three-wave longitudinal study tested two transdiagnostic mediators – anger and racism-related vigilance – of the link between racism and internalizing and externalizing problems. At Wave 1, the sample included 344 Mexican-origin adolescents (Mage = 13.5 years; 51.7% male, 45.9% female; 2.3% non-binary) residing in the Midwestern United States. Data across the three waves were collected from April 2021 through October 2024. The study examined how both direct and vicarious racism were related to internalizing and externalizing problems over time. Results from latent growth curve mediation analyses indicated that outward anger expression was a significant mediator; both direct and vicarious racism at Wave 1 were significantly associated with higher levels of anger at Wave 2, which in turn, were associated with higher levels of internalizing and externalizing problems at Wave 3. Racism-related vigilance was a significant mediator of the association between vicarious racism and internalizing problems only, according to results from post hoc sensitivity analyses. Implications for future theory, research, and clinical practice are discussed to help mitigate the effects of racism in new migration contexts for this vulnerable population.

Caregiver sensitivity to infant cues is well-established as a predictor of child development. Infants also actively influence their social environment, especially their caregivers, even from their earliest days. Sensory reactivity, characterized as hypo- (under) and hyper- (over) responding to environmental stimuli, is one domain of development that is likely to influence caregiver-infant interaction, due to its role in regulating emotions and responses to both physical and social stimuli. Although sensory reactivity could be an important target for improving caregiver-child interaction, the longitudinal, reciprocal relations between infant sensory reactivity and caregiver behaviors are currently unknown. In the present proof-of-concept study, we examined these associations in a community sample of mother-infant dyads (N = 252) at infant ages 6 and 12 months using a cross-lagged panel modeling approach. Preliminary findings, which will benefit from replication using a validated measure of sensory reactivity, indicated that maternal sensitivity may decrease infant hyperreactivity, and infant hyporeactivity may be associated with increases in maternal sensitivity. Maternal intrusiveness appears to exacerbate infant hyperreactivity over time and attenuate later infant hyporeactivity. The results of this study provide preliminary evidence for the mutually influential nature of infant sensory reactivity and maternal behavior and signals the importance of future investigation of these concepts.

Previous research reports that offspring of parents with histories of childhood maltreatment are at increased risk for mental health problems, yet the mechanisms remain unclear. This study examines the extent to which parent psychopathology mediates the relationship between parent maltreatment history and offspring psychopathology. Using a prospective cohort design, individuals with documented histories of childhood maltreatment (ages 0 – 11 years) during 1967 – 1971 and demographically matched controls were followed into adulthood and first interviewed in 1989-1995 (N = 1,196). Offspring (N = 697, Mage = 22.8 years) were assessed in 2009 – 2010. A general p-factor structure and a model with specific latent constructs were tested. Structural equation modeling was used for mediation. The results indicated that only minor offspring of maltreated parents exhibited more symptoms of depression than offspring of controls. Parent psychopathology predicted offspring psychopathology. Parent depression and dysthymia predicted greater offspring depression, anxiety, PTSD, alcohol use, drug use, and marijuana use. Parent anxiety and alcohol and drug symptoms also predicted offspring alcohol symptoms. There was no evidence that parent psychopathology explained the relationship between a parent’s history of maltreatment and their offspring’s psychopathology. These new results suggest that reconsideration of some assumptions about the intergeneration impacts of maltreatment may be warranted.

Treatment response in pediatric social anxiety disorder (SAD) is highly variable, and symptoms may be maintained by maladaptive attention. A previous study found that youth with SAD scan a more restricted area of faces than healthy controls during emotion recognition, potentially limiting interpretation of social cues. The current study followed up on these results by examining whether restricted face scanning 1) predicts response to psychological treatment, and 2) changes with successful treatment. Youth with SAD (n = 59) were assessed prior to treatment with internet-delivered cognitive behavioral therapy (ICBT) or supportive therapy (ISUPPORT) and then again three months after treatment. Restricted scanning of faces predicted a smaller symptom reduction, independent of treatment arm. Scanpath distribution was moderately stable from T1 to T2 and did not change with treatment. Restricted scanning of faces may be a risk factor for sustained SAD symptoms after therapy. As the visual scanpath is a key aspect of human visual processing, inflexible scanning could potentially interfere with information processing. Implications for theories of attention in pediatric SAD are discussed.

The study is the first to examine the effects of children’s and therapists’ in-session behaviors on later therapeutic alliance (TA; i.e., relational bond, task collaboration) as rated by children and therapists in an intervention for children with aggressive behavior. One hundred eighty children (ages 9.3–11.8; 69% male; 78% Black), screened as having aggressive behavior by teacher and parent ratings, received a 32-session group-based cognitive-behavioral intervention (Coping Power) at their schools. TA ratings were collected from children and therapists at mid- and end-of-intervention using the Therapeutic Alliance Scale for Children. Children’s and therapists’ behaviors during the first 16 sessions were coded by independent observers. Children’s negative in-session behaviors predicted lower child- and therapist-rated TA (averaged across mid- and end-of-intervention). Children’s in-session positive behaviors, at both the individual and group-wide level, predicted higher later TA. Therapists’ efforts to manage deviant behavior predicted stronger child-reported ratings of the relational bond and of child- and therapist-rated task collaboration. Exploratory analyses indicate that the effect of children’s in-session behaviors on later TA is moderated by therapists’ skills in managing the group and in managing deviant talk and behavior in sessions. Clinical and research implications of the findings are discussed.

Executive attention, an underlying mechanisms enabling self-regulation, can be behaviorally indicated by post-error slowing (PES) – a delay in reaction time following an error. PES develops during early childhood – plausibly shaped by genetic and environmental factors. We tested whether mothers’ and children’s PES predicted their post-traumatic stress disorder (PTSD) symptoms during a real-life stressful situation, and how each one’s PTSD symptoms moderated the other’s. Ninety-five kindergarten-aged children and mother pairs participated. In T1, participants’ PES was measured during a laboratory task. About 1.5 years afterwards, six months after a national traumatic event, mothers reported their own and their child’s PTSD symptoms (T2). Key findings show that for mothers with high PTSD symptoms, children with more developed PES at T1 showed less PTSD symptoms at T2. In contrast, for mothers with low PTSD symptoms, children’s PES was unrelated to their PTSD symptoms. For mothers of children with high PTSD symptoms, those with less developed PES at T1 showed high PTSD symptoms at T2. Mothers of children with low symptoms showed no such relation. The models explained 61.1% of children’s and 51% of mothers’ PTSD symptoms. These findings provide evidence for the protective effect of self-regulation against PTSD, and the mutual dyadic moderating effects of its manifestation.
