Predicting young adult social functioning from developmental trajectories of externalizing behaviour

Cumulative contextual risk, mothers' and fathers' parenting, and adolescents' psychosocial problems in Ghana

Limited research exists on the association between cumulative risk factors and the psychosocial well-being of adolescents in low-income, culturally distinct settings. This study aimed to fill this gap by examining the impact of cumulative risk exposure on Ghanaian adolescents' psychosocial problems and exploring the mediating role of parenting. The study involved 212 adolescents (61% girls; average age = 13.38) who completed measures on cumulative risk, maternal and paternal warmth, behavioral control, anxiety, depression, overt aggression, and relational aggression. The results indicated that cumulative risk indirectly influenced adolescents' depression and overt aggression through paternal warmth. Furthermore, paternal behavioral control mediated the relationship between cumulative risk and adolescents' overt aggression. Findings highlight the importance of fathers' parenting in mediating cumulative risk effects.

Parental Deprivation- and Threat-Based Factors Associated with Youth Emotion-Based Neurocircuitry and Externalizing Behavior: A Systematic Review

Parental factors, including negative parenting practices (e.g., family conflict, low monitoring), parental depression, and parental substance use, are associated with externalizing behaviors among youth. However, the ways in which these parental factors are associated with youth brain function and consequent externalizing behavior has been less studied. Both the dimensional and stress acceleration models provide frameworks for understanding how parental factors may be associated with frontolimbic and frontoparietal networks implicated in emotional attention and regulation processes. The current review builds upon this work by examining how deprivation- and threat-based parental factors are associated with youth neurocircuitry involved in emotional functioning and externalizing behaviors. A systematic review using PRISMA guidelines was completed and included five studies assessing parenting behaviors, six studies assessing parental depressive symptoms and/or diagnosis, and 12 studies assessing parental history of substance use. Synthesis of reviewed studies discusses support for the dimensional and stress acceleration models within the context of deprivation and threat. Further, a limited number of studies tested (i.e., six studies) and supported (i.e., three studies) youth neural structure and function as a mediator of the association between parental factors and youth externalizing behavior. Specific recommendations for future work include more deliberate planning related to sample composition, improved clarity related to parental constructs, consistency in methodology, and longitudinal study design in order to better understand associations between contextual parental influences and youth neural and behavioral functioning.

Specialized and versatile antisocial behavioral profiles in preschoolers: Associations with persistent behavioral problems

This study investigated specialized and versatile antisocial patterns in preschoolers and examined the link between these patterns and the risk of developing chronic antisocial behaviors throughout childhood. A total of 556 children (50.6% boys, 88% White) participated in this three-wave longitudinal study at 3-5, 6-8, and 10-12 years old. A latent transition analysis revealed that most preschoolers (89.5%) who adopt several subtypes of antisocial behaviors simultaneously exhibit stable and severe antisocial behaviors throughout childhood. In contrast, most preschoolers (60%) who favor one specific subtype of antisocial behaviors desist from such behaviors between preschool and preadolescence. Importantly, aggression accompanied by other subtypes of antisocial behaviors predicted chronicity better than aggression alone, casting doubt on the notion that aggression is the strongest predictor of chronicity.

Differential processing of risk and reward in delinquent and non-delinquent youth

The present study examined the behavioral and neural differences in risky decision-making between delinquent (n = 23) and non-delinquent (n = 27) youth ages 13-17 years (M = 16, SD = 0.97) in relation to reward processing. While undergoing functional neuroimaging, participants completed an experimental risk task wherein they received feedback about the riskiness of their behavior in the form of facial expressions that morphed from happy to angry. Behavioral results indicated that delinquent youth took fewer risks and earned fewer rewards on the task than non-delinquent youth. Results from whole-brain analyses indicated no group differences in sensitivity to punishments (i.e. angry faces), but instead showed that delinquent youth evinced greater neural tracking of reward outcomes (i.e. cash-ins) in regions including the ventral striatum and inferior frontal gyrus. While behavioral results show that delinquent youth were more risk-averse, the neural results indicated that delinquent youth were also more reward-driven, potentially suggesting a preference for immediate rewards. Results offer important insights into differential decision-making processes between delinquent and non-delinquent youth.

Withdrawn Behavior in Preschool: Implications for Emotion Knowledge and Broader Emotional Competence

The present study investigated the respective roles of withdrawal, language, and context-inappropriate (CI) anger in the development of emotion knowledge (EK) among a subsample of 4 and 5 year-old preschoolers (n = 74). Measures included parent-reported withdrawn behavior, externalizing behavior, and CI anger, as well as child assessments of receptive language and EK. Ultimately, findings demonstrated that receptive language mediated the relationship between withdrawn behavior and situational EK. However, CI anger significantly interacted with receptive language, and, when incorporated into a second-stage moderated mediation analysis, moderate levels of CI anger rendered the indirect effect of withdrawn behavior on situational EK via receptive language insignificant. Cumulatively, these findings demonstrate a mechanism by which withdrawal may impact EK. They also indicate that such an effect may be attenuated in children with moderate levels of CI anger. Implications of these findings are discussed.

Individual differences in the development of youth externalizing problems predict a broad range of adult psychosocial outcomes

This study examined how youth aggressive and delinquent externalizing problem behaviors across childhood and adolescence are connected to consequential psychosocial life outcomes in adulthood. Using data from a longitudinal, high-risk sample (N = 1069) that assessed children and their parents regularly from early childhood (ages 3-5) through adulthood, multilevel growth factors of externalizing behaviors were used to predict adult outcomes (age 24-31), providing a sense of how externalizing problems across development were related to these outcomes via maternal, paternal, teacher, and child report. Findings indicated strong support for the lasting connections between youth externalizing problems with later educational attainment and legal difficulties, spanning informants and enduring beyond other meaningful contributors (i.e., child sex, cognitive ability, parental income and education, parental mental health and relationship quality). Some support was also found, although less consistently, linking externalizing problems and later alcohol use as well as romantic relationship quality. Delinquent/rule-breaking behaviors were often stronger predictors of later outcomes than aggressive behaviors. Taken together, these results indicate the importance of the role youth externalizing behaviors have in adult psychosocial functioning one to two decades later.

Outcomes of serious antisocial behavior from childhood to early adulthood in two Puerto Rican samples in two contexts

PURPOSE

The patterns or trajectories of serious antisocial behavior (ASB) in children are examined to determine the extent to which context, gender, and the severity and persistence of ASB from childhood/early adolescence to later adolescence/early adulthood is associated with negative outcomes.

METHODS

A four wave longitudinal study obtained data on two multi-stage probability household samples of Puerto Rican background children (5-13 years at baseline) living in the San Juan Metropolitan Area of Puerto Rico (PR) and the South Bronx (SBx) of New York. The outcomes studied were any psychiatric disorder including substance use disorders and teenage pregnancy.

RESULTS

Both males and females raised in the SBx had much higher risk of serious ASB (42.3%) as compared to those in PR (17.8%). Concurrent ASB4 + in the fourth wave was strongly related to SUD and MDD for both males and females at Wave 4.

CONCLUSIONS

Serious ASB is likely to persist at least to the next developmental period of a child and is likely to be associated with substance use disorders and major depression later in life.

The Development of Externalizing and Internalizing Behaviors Among Youth With or Without a Family History of Substance Use Disorder: The Indirect Effects of Early-Life Stress and Impulsivity

Youth with a family history of substance use disorder (FH+) are more prone to have externalizing and internalizing problems compared to youth without a family history of substance use disorder (FH-), increasing the likelihood of later maladjustment. However, mechanisms for this association remain understudied. In this longitudinal study, we examined if FH+ youth are more likely to experience early-life stressors (ELS), which in turn would increase impulsivity and the expression of externalizing and internalizing behaviors. Data were collected from youth and a parent (n = 386) during a baseline assessment (age 10-12 years) and every six months when the youth was 13-16 years old. In support of the primary hypothesis, FH+ youth reported higher levels of externalizing and internalizing behaviors through ELS to impulsivity providing a developmental pathway through which FH+ youth are more prone to externalizing and internalizing problems.

Mapping Pathways by Which Genetic Risk Influences Adolescent Externalizing Behavior: The Interplay Between Externalizing Polygenic Risk Scores, Parental Knowledge, and Peer Substance Use

Genetic predispositions and environmental influences both play an important role in adolescent externalizing behavior; however, they are not always independent. To elucidate gene-environment interplay, we examined the interrelationships between externalizing polygenic risk scores, parental knowledge, and peer substance use in impacting adolescent externalizing behavior across two time-points in a high-risk longitudinal sample of 1,200 adolescents (764 European and 436 African ancestry; Mage = 12.99) from the Collaborative Study on the Genetics of Alcoholism. Results from multivariate path analysis indicated that externalizing polygenic scores were directly associated with adolescent externalizing behavior but also indirectly via peer substance use, in the European ancestry sample. No significant polygenic association nor indirect effects of genetic risk were observed in the African ancestry group, likely due to more limited power. Our findings underscore the importance of gene-environment interplay and suggest peer substance use may be a mechanism through which genetic risk influences adolescent externalizing behavior.

Family Functioning in Families of Adolescents with Mental Health Disorders: The Role of Parenting Alliance

This study primarily examined the predictive role of emotional and behavioral disorders in family cohesion and the moderating role of parenting alliance. Adolescents’ mental health issues are a major concern, with important implications for individuals and their families. However, the impact of mental disorders on family processes has been less widely studied. Participants in this study were 72 parents of adolescent beneficiaries of mental health services. Questionnaires assessed family cohesion, parenting alliance, and sociodemographic factors. Results indicated that emotional and behavioral disorders did not have an influence on family cohesion. They also suggested that parenting alliance may be a protective factor for family cohesion. This paper highlights the role of parenting alliance as a potential protective factor in positive family processes. These findings support the importance of focusing on the parental subsystem in therapy, and the need to incorporate a positive parenting perspective when working with these families.

Maternal depression trajectories and child executive function over 9 years

BACKGROUND

The present study aimed to assess the relationship between maternal depression trajectories from pregnancy to 2 years after childbirth and childhood behavioral problems and executive function at 9 years.

METHODS

Data of mother-child pairs (N = 1191) extracted from the Panel Study on Korean Children (a cohort study) were used. Maternal depression was assessed using the Kessler depression scale during pregnancy and at 6 months, 1 years, and 2 years postpartum. At ages 4, 5, 6, 7, and 9 years, the children's behavioral outcomes were assessed using the Child Behavior Checklist. The children's executive function was assessed using the Executive Function Difficulty Screening Questionnaire at ages 7, 8, and 9 years. We performed a latent profile analysis to identify maternal depression trajectories and compared the children's behavioral problems and executive function among different trajectories.

RESULTS

According to maternal depression trajectory, the mother-child pairs were divided into the no symptom (n = 503), mild symptom (n = 558), and moderate symptom (n = 130) groups. Children of mothers with significant depressive symptoms had severe behavioral problems at ages 4, 5, 6, 7, and 9 years. Moreover, compared with children whose mothers were not depressed, those whose mothers had mild or moderate symptoms had impaired executive function at ages 7, 8, and 9 years.

CONCLUSIONS

Maternal depression up to 2 years after childbirth affects childhood behavior and executive function into middle childhood.

A long-term look at "early starters": Predicting adult psychosocial outcomes from childhood conduct problem trajectories

Current evidence suggests that multiple pathways of "early-starting" conduct problems exist, including persisting and declining trajectories. Since relatively little is known about the early onset-declining pathway, this study examined the long-term outcomes of different childhood conduct problem trajectories in a disproportionately high-risk sample (N = 754). Parents reported on children's conduct problems at six time points (kindergarten to grade 7). At age 25, psychosocial outcomes were assessed across five domains (psychopathology, substance use, risky sexual behavior, antisocial behavior, and adaptive outcomes). Four childhood conduct problem trajectories were identified: extremely high increasing (EHI; 3.7%), high stable (HS; 22.0%), moderate decreasing (MD; 38.8%), and low decreasing (LD; 35.5%). The EHI and HS groups displayed the poorest psychosocial functioning at age 25, whereas the LD group exhibited the most positive adjustment. Although individuals in the MD group displayed relatively positive adjustment on some outcomes, they displayed more psychopathology and lower well-being in adulthood than the LD group. These findings suggest that there are diverse pathways of early-starting conduct problems, and that all early starters are at risk for later maladjustment. However, the degree and type of risk is related to the severity of conduct problems throughout childhood.

Examining income dynamics and externalizing and internalizing trajectories through a developmental psychopathology lens: A nationally representative study

Prior research has documented elevations in levels of internalizing and externalizing behaviors among children in lower income families in comparison to more advantaged peers. However, most studies focus on behavior problems at a single point in time or within a short developmental period. Associations between income dynamics and developmental trajectories of behavior problems over time are less understood. To address this, the current study uses data from the National Longitudinal Study of Youth (N = 7,476; 50.8% male) to examine how income dynamics (annual income and income volatility) across three distinct developmental periods from early childhood to early adolescence relate to trajectories of externalizing and internalizing problems. Group-based mixture modeling revealed a five-group trajectory model for externalizing behavior and a four-group trajectory model for internalizing behavior. Higher cumulative annual income predicted greater likelihood of belonging to the low-stable group compared to the other, more problematic groups for both externalizing and internalizing trajectories. In addition, income losses predicted higher risk of membership in any group other than the low-stable group for internalizing and externalizing behavior. Developmental period-specific income dynamics, though not as consistent as cumulative dynamics, also predicted trajectory group membership.

Stability and Change in Patterns of Adolescent Antisocial Behavior

Research examining relations between various types of antisocial behavior (ASB) have generally been based on cross-sectional data. Although there is a strong correlation between types of ASB, it has been less common to examine how patterns of adolescents’ problems vary over time. This study used a person-oriented approach to examine patterns of ASB in adolescents longitudinally and also investigated how these patterns were associated with three outcomes. The sample consisted of 778 Swedish adolescents in grade 7 (13 years old) followed over time to grade 9. Patterns of ASB were identified based on adolescent-reported tobacco and alcohol use, truancy, bullying in school, and delinquency. The outcomes were drug use, depressive symptoms, and missing grades in grade 9. Results revealed an escalation in the frequency and seriousness of ASB over time, although the largest single cluster over time evidenced no ASB. One cluster in particular increased the risk of drug use, depression, and missing grades at grade 9. Results are discussed in relation to school-based prevention efforts.

Behavioral and Neural Dysregulation to Social Rewards and Links to Internalizing Symptoms in Adolescents

Adolescence is a time of unique sensitivity to socially salient stimuli such as social rewards. This period overlaps with the onset of psychopathology such as internalizing and externalizing symptoms. In the current studies, we examined behavioral and neural patterns of dysregulation to social rewards and threats, and links to internalizing and externalizing symptoms in youths. In study 1, we used a social Go/NoGo cognitive control task using peer faces to test for age-related behavioral differences in inhibitory failures in adolescents (N = 53, Mage = 13.37 years), and adults (N = 51, Mage = 43.71 years). In study 2, an independent adolescent sample (N = 51, Mage = 13.98 years) completed a similar social Go/NoGo cognitive control task during fMRI. Results show that adolescents had greater inhibitory failures - as measured by false alarm rate - to both social reward and threat cues than adults, and more so to social reward than threat cues. Greater inhibitory failures to social reward than threat cues were associated with greater internalizing symptoms, but were not significantly related to externalizing symptoms. At the neural level, greater inhibitory failures to social reward than threat cues as well as greater internalizing symptoms were both associated with heightened amygdala-ventral striatum connectivity. Our findings indicate that subcortico-subcortical connectivity, which is deemed to occur chronologically earlier and thus necessary for subcortico-cortical circuits, may serve as an early biomarker for emotion dysregulation and a risk factor for internalizing symptoms.

Risk Factors Associated With Boys' and Girls' Developmental Trajectories of Physical Aggression From Early Childhood Through Early Adolescence

Importance

This study used multitrajectory modeling to identify distinct trajectories of physical aggression from ages 1.5 to 13 years for boys and girls.

Objectives

To trace the development of boys' and girls' physical aggression problems from infancy to adolescence using mother ratings, teacher ratings, and self-ratings and to identify early family predictors of children on the high physical aggression trajectories.

Design, Setting, and Participants

This cohort study used data from the Quebec Longitudinal Study of Child Development (QLSCD), a study of a representative, population-based sample of 2223 infants born in 1997 and 1998 in the Canadian province of Quebec. The dates of analysis were January 2017 to January 2018.

Main Outcomes and Measures

Trained research assistants conducted 7 interviews (at child ages 1.5, 2.5, 3.5, 4.5, 5, 6, and 8 years) with the person most knowledgeable about the child (mothers in 99.6% [2214 of 2223] of cases). Teachers assessed the child's behavior at ages 6, 7, 8, 10, 12, and 13 years. Self-reports of behavior problems were obtained from the child at ages 10, 12, and 13 years.

Results

The sample included 2223 participants, 51.2% of whom were boys and 91.2% of whom were of white race/ethnicity. The mean response rate for mother ratings of physical aggression during the first 8 years of life was 80.9% (range, 65.1%-91.7%). For teacher ratings of physical aggression from ages 6 to 13 years, the mean response rate was 45.7% (range, 35.4%-56.9%), while the mean response rate of physical aggression assessment from self-ratings between ages 10 and 13 years was 57.9% (range, 55.2%-60.5%). Attrition was higher among families with low socioeconomic status and single-parent families, as well as among young mothers and mothers who were not fluent in French or English. A statistical analysis to examine the consequences of attrition was included. For boys and girls, the frequency of physical aggressions increased from age 1.5 years (2039 [91.7%]) to age 3.5 years (1941 [87.3%]) and then substantially decreased until age 13 years (1228 [55.2%]). Three distinct developmental trajectories of physical aggression were observed for girls and 5 for boys. Most family characteristics measured at 5 months after the child's birth were associated with a high physical aggression trajectory for boys and girls.

Conclusions and Relevance

Family characteristics at 5 months after the child's birth could be used to target preschool interventions aimed at preventing the development of boys' and girls' chronic physical aggression problems.

Behavioral Trajectories During Middle Childhood: Differential Effects of the School-Wide Positive Behavior Support Model

The aims of this study were to assess the longitudinal trajectories of externalizing problem behavior during middle childhood among typically developing children and to examine subgroup differences in the effectiveness of the School-Wide Positive Behavior Support (SWPBS) model, called N-PALS in Norway. Participants were approximately 3000 students, and behavioral assessments were performed by class head teachers at four time points from the 4th or 5th grade through the 7th grade. Using a combination of latent class growth analyses (LCGA) and growth mixture modeling (GMM), four distinct trajectory classes were identified, i.e., persistent low (84.4%), persistent high (2.5%), decreasing (7.9%), and increasing (5.3%). An indication of a significant positive effect of the N-PALS model was found for students with a persistently high-risk trajectory. The current study adds to the evidence that this school-wide prevention model can moderate the development of externalizing behavior problems among children and youth.

Childhood Predictors of Young Adult Social Functioning in 22q11.2 Deletion Syndrome

The primary objectives of the current prospective longitudinal study were to (a) describe social functioning outcomes and (b) identify childhood predictors of social functioning in young adults with 22q11.2 deletion syndrome (22q11.2DS). Childhood predictors of young adult social functioning were examined. Family environment and parental stress in adolescence were investigated as potential mediators between childhood variables and adult social functioning. Parent rated childhood internalizing symptoms significantly predicted young adult social functioning in 22q11.2DS, even after controlling for concurrent positive symptoms of psychosis, and problem behaviors contributing to parenting stress in adolescence partially mediated this relationship. These findings highlight child internalizing symptoms and adolescent problem behaviors as potential targets for social functioning interventions in 22q11.2DS.

Classifying trajectories of social-emotional difficulties through elementary school: Impacts of the Chicago school readiness project

Although research has shown fade-out of the cognitive benefits of classroom-based preschool interventions, less is known regarding the durability of social-emotional impacts. This study examines the extent to which the multicomponent Chicago School Readiness Project (CSRP) intervention lowered risk of internalizing, externalizing, attention, and social difficulties from Head Start through elementary school for 602 low-income children. Results suggest that most children in this sample showed few social-emotional difficulties over time. However, one quarter of the sample exhibited profiles of transitory or building difficulties over six years. Random assignment to the CSRP preschool intervention significantly reduced children's odds of transitory attention and social difficulties in middle childhood, with preliminary evidence suggesting stronger impacts for children attending elementary schools characterized by low academic rigor and high neighborhood crime. CSRP was not found to be effective in preventing more robust, increasing forms of difficulty in the externalizing and attention domains. Implications for early childhood intervention and policy are discussed. (PsycINFO Database Record

The predictors of perceived social support among former foster youth

Based on a 5-wave panel survey of 732 foster youth, the current study examined the respective relationships between foster youths' individual characteristics, youths' social connections with individuals and formal institutions, and the development of perceived social support across the transition to adulthood. Several youth characteristics - including self-reported delinquency and attachment insecurity - were found to be statistically significantly associated with perceived social support. Attachment insecurity also appeared to mediate the relationships between social support and several other youth-level characteristics, including prior placement disruptions and placement with relatives. Social connections with different types of individuals - including caregivers, relatives, natural mentors, and romantic partners - were found to be associated with additive increases in perceived social support. However, some types of connections (e.g., romantic partners, natural mentors) appeared to be associated with much larger increases in social support than other connections (e.g., school or employment). Collectively, the findings help inform agencies' efforts to bolster foster youths' social connections as they transition to adulthood.

Assessing Variations in Developmental Outcomes Among Teenage Offspring of Teen Mothers: Maternal Life Course Correlates

This study investigated potential heterogeneity in development among offspring (age 17) of teen mothers and maternal life course as correlates of variation. Using latent class analysis, subgroups of developmental outcomes were identified. Maternal standing in two life course realms (i.e., socioeconomic and domestic) was considered as a potential explanation for heterogeneity in offspring's development. Offspring reported on measures assessing their psychological, academic, and behavioral development. Teen mothers reported on measures of life course realms. Three subgroups of developmental outcomes were identified: on track (52%), at risk (37%), and troubled (11%). Findings suggest that economic hardship and number of pregnancies among teen mothers distinguish developmental patterns among teenage offspring, whereas teen mothers' educational attainment and marital status do not.

Developmental Trajectories of Youth Conduct Problems: Testing Later Development and Related Outcomes in a 12-Year Period

Developmental heterogeneity of youth conduct problems has been widely assumed, leading to the identification of distinctive groups at particular risk of more serious problems later in development. The present study intends to expand the main results of a prior study focused on identifying developmental trajectories of conduct problems (Stable-low, Stable-high, and Decreasing), by analyzing their developmental course and related outcomes during middle/late adolescence and early adulthood. Two follow-up studies were conducted 10 and 12 years after the initial study with 115 and 122 youths respectively (mean = 17.29 and 19.18). Overall results underline that the Early-onset persistent group showed the highest risk-profile; the Childhood-limited group revealed a moderate level of later maladjustment; and the Adolescence-onset group, currently identified, showed a significant peak of risk particularly in middle/late adolescence. These findings provide a more comprehensive representation of youth conduct problems, and open new means of discussion in terms of preventive intervention.

Gender Differences in at Risk Versus Offender Adolescents: A Dimensional Approach of Antisocial Behavior

The current study investigated gender differences in the main components of antisocial behavior in an at-risk versus an offender group of adolescents. One-hundred and forty-three adolescents divided into two different risk groups [at risk (n = 54) and offenders (n = 89)] were compared according to gender (111 boys and 32 girls). Externalizing symptoms were assessed with the Delinquent and Aggressive subscales of the Youth Self-report Questionnaire, internalizing problems with the Beck Anxiety Inventory and the Beck Depressive Inventory and personality traits with the Barratt-Impulsiveness Scale as well as the Youth Psychopathic Traits Inventory. Results revealed a consistent interaction pattern, with girls presenting higher levels of externalizing symptoms, more motor impulsivity and a more arrogant and deceitful interpersonal style than boys in the at-risk group. In contrast, in the offenders' group, psychopathic traits were more present in boys than in girls. Regarding internalizing problems, girls showed more depression than boys, independently of the risk group. Among offending youths, girls present equally severe externalizing problems, and problematic personality traits as boys. At-risk girls have the highest rates of difficulties across the tested domains and should therefore be specifically targeted for prevention and intervention.

Alexithymia and psychosocial problems among Italian preadolescents. A latent class analysis approach

The study, conducted on Italian preadolscents aged 11 to 13 belonging to the general population, aims to investigate the relationship between the emotional functioning, namely, alexithymia, and the risk of developing behavioral and emotional problems measured using the Strength and Difficulty Questionnaire. The latent class analysis approach allowed to identify two latent variables, accounting for the internalizing (emotional symptoms and difficulties in emotional awareness) and for the externalizing problems (conduct problems and hyperactivity, problematic relationships with peers, poor prosocial behaviors and externally oriented thinking). The two latent variables featured two latent classes: the difficulty in dealing with problems and the strength to face problems that was representative of most of the healthy participants with specific gender differences. Along with the analysis of psychopathological behaviors, the study of resilience and strengths can prove to be a key step in order to develop valuable preventive approaches to tackle psychiatric disorders.

Feedback learning and behavior problems after pediatric traumatic brain injury

BACKGROUND

Feedback learning is essential for behavioral development. We investigated feedback learning in relation to behavior problems after pediatric traumatic brain injury (TBI).

METHOD

Children aged 6-13 years diagnosed with TBI (n = 112; 1.7 years post-injury) were compared with children with traumatic control (TC) injury (n = 52). TBI severity was defined as mild TBI without risk factors for complicated TBI (mildRF- TBI, n = 24), mild TBI with ⩾1 risk factor for complicated TBI (mildRF+ TBI, n = 51) and moderate/severe TBI (n = 37). The Probabilistic Learning Test was used to measure feedback learning, assessing the effects of inconsistent feedback on learning and generalization of learning from the learning context to novel contexts. The relation between feedback learning and behavioral functioning rated by parents and teachers was explored.

RESULTS

No evidence was found for an effect of TBI on learning from inconsistent feedback, while the moderate/severe TBI group showed impaired generalization of learning from the learning context to novel contexts (p = 0.03, d = -0.51). Furthermore, the mildRF+ TBI and moderate/severe TBI groups had higher parent and teacher ratings of internalizing problems (p's ⩽ 0.04, d's ⩾ 0.47) than the TC group, while the moderate/severe TBI group also had higher parent ratings of externalizing problems (p = 0.006, d = 0.58). Importantly, poorer generalization of learning predicted higher parent ratings of externalizing problems in children with TBI (p = 0.03, β = -0.21) and had diagnostic utility for the identification of children with TBI and clinically significant externalizing behavior problems (area under the curve = 0.77, p = 0.001).

CONCLUSIONS

Moderate/severe pediatric TBI has a negative impact on generalization of learning, which may contribute to post-injury externalizing problems.

Do specific transitional patterns of antisocial behavior during adolescence increase risk for problems in young adulthood?

Latent transition analysis was used to identify patterns and trajectories of antisocial behavior (ASB) and their association with young adult outcomes in a nationally representative sample of adolescents (N = 5,422; 53.9% female). Participants were on average 13.96 years of age (SD = 1.06) at wave 1 of the study. Latent class analysis identified four classes of ASB including a non-ASB class, an aggressive class, a petty theft class, and a serious ASB class. In general, youth who were classified as serious stable ASB were the most at risk for problematic functioning in young adulthood. Youth who escalated to more serious patterns of ASB or reduced involvement also were at greater risk of negative outcomes in young adulthood compared to stable non-ASB youth, although they generally fared better than youth involved in stable patterns of more serious ASB. Gender differences indicated that involvement in ASB was a greater risk factor for alcohol use among boys and a greater risk factor for depression among girls in young adulthood. Results are discussed in terms of the predictive validity of classes of ASB to functioning in young adulthood and the implications of this research for prevention efforts.

Distinguishing among disruptive behaviors to help predict high school graduation: does gender matter?

This study examined unique predictive associations of aggressive and hyperactive-inattentive behaviors in elementary school with high school graduation. The current study also investigated whether these associations were moderated by gender. At Time 1, 745 children in the 3rd through 5th grades completed peer ratings on their classmates' disruptive behaviors. At Time 2, school records were reviewed to determine whether students graduated within four years of entering high school. Results showed that gender and hyperactivity-inattention are uniquely associated with high school graduation, but childhood aggression is not. Results also indicated that gender moderated associations between hyperactivity-inattention and graduation. Among boys, hyperactive-inattentive behaviors were not significantly associated with graduation, above and beyond aggression. In contrast, among girls, hyperactive-inattentive behaviors in childhood were significantly associated with graduation even after controlling for aggression. These findings suggest that in middle childhood, hyperactive-inattentive behaviors may be a more meaningful predictor of high school graduation than other forms of early disruptive behavior (e.g., aggression), especially for girls. Such findings could have significant implications for prevention and intervention programs designed to target children at risk for dropping out of school.

Psychopathology and academic performance, social well-being, and social preference at school: the TRAILS study

Psychopathology during adolescence has been associated with poor academic performance, low social well-being, and low social preference by peers at school. However, previous research has not accounted for comorbid psychopathology, informant-specific associations between psychopathology and functioning, and gender and age differences. This study addresses these limitations by examining adolescents' psychopathology and functioning at school, reported by child, parent, teacher, and peers during primary and secondary school in a large Dutch longitudinal cohort study (N = 2230). Teacher reports of psychopathology, especially regarding attention problems and withdrawn/depressed problems, followed by parent reports regarding hyperactivity, were most strongly associated with academic performance. The same held for social preference which was associated with teacher and parent ratings of withdrawn/depressed problems and hyperactivity. In contrast, social well-being was best predicted by child reports (at primary school) of affective problems. In girls, the association between ADHD problems and poor academic performance was stronger than in boys and conduct problems were more often associated with poor school functioning in general. These findings can help identify adolescents at risk for poor functioning and design interventions that effectively reduce or prevent poor school functioning.

Revisiting data related to the age of onset and developmental course of female conduct problems

Children who exhibit persistently elevated levels of conduct problems (CP) from early childhood, so-called early-starters, are known to be at increased risk for continued CP throughout middle childhood, adolescence, and adulthood. Theoretical and empirical work has focused on this subgroup of children characterized by similar risk factors, an early age of onset, and a persistent developmental course of CP. However, females were historically neglected from this literature. Although research on female CP has increased, conclusions drawn from limited prior work continue to predominate. The primary aim of this review was to evaluate the updated literature to determine the percentage of females who show the early-starter CP pattern relative to two other trajectories often theorized to be more characteristic of females: early-starting desisting and adolescent-onset CP. The findings suggest that a subgroup of females exhibits an early-starting and persistent CP pattern, while a separate group of females demonstrates an onset of CP in adolescence. In addition, although it has been argued that females with childhood CP are not likely to show CP into adolescence and adulthood, evidence for early-starting desisting CP was inconsistent. The results are discussed with respect to implications for developmental taxonomy theory and future basic research in the area of CP development, as well as intervention efforts.

Instruments measuring externalizing mental health problems in immigrant ethnic minority youths: a systematic review of measurement properties

BACKGROUND

Little is known about reliability and validity of instruments measuring externalizing mental health problems in immigrant ethnic minority youths.

AIMS

To provide an overview of studies on measurement properties of instruments measuring these problems in immigrant ethnic minority youths, their methodological quality and results.

METHODS

A systematic review of the literature in MEDLINE, EMbase, PsycINFO and Cochrane Library was performed. Evaluation of methodological quality of studies found was done by using the 'COSMIN-checklist'. Full text, original articles, published in English after 1990 were included. Articles had to concern the development or evaluation of the measurement properties of self-reported, parent-reported and/or teacher- or clinician-reported questionnaires assessing or screening externalizing mental health problems in immigrant ethnic minority youths. Specific results of analyses on (an) immigrant ethnic minority group had to be given.

RESULTS

Twenty-nine studies evaluating 18 instruments met our criteria. Most studies concerned instruments with known validity in Western populations, tested mainly in African Americans. Considering methodological quality, inequivalences between ethnicities were found, self-reports seemed to perform better, and administration of an instrument influenced reliability and validity.

CONCLUSION

It seems that the majority of instruments for assessing externalizing problems in immigrant ethnic minority youths is currently not sufficiently validated. Further evaluating existing instruments is crucial to accurately assess and interpreted externalizing problems in immigrant ethnic minority youths.

Early predictors of boys' antisocial trajectories

Despite the large number of studies tracing patterns of youth antisocial behavior (AB) during adolescence, few have prospective data on the developmental precursors of AB beginning during infancy. Using a cohort of 268 low-income boys first assessed at 18 months, the current study examined predictors of early- and late-starting trajectories of AB assessed during early childhood and early adolescence. Four trajectory groups were identified, including early- and late-starting groups, a low stable group, and a high decreasing group, characterized by multiple risk factors during early childhood and early adolescence. During early childhood, parenting and maternal depression discriminated two AB trajectory groups, an early-starting and a high decreasing group, who would go on to demonstrate a high preponderance of juvenile court involvement (60% to 79%) and elevated rates of clinical depression 13 to 15 years later. The results were discussed in reference to targeting malleable family risk factors during early childhood associated with patterns of AB and mental health disorders during adolescence.

Early environment and neurobehavioral development predict adult temperament clusters

Background

Investigation of the environmental influences on human behavioral phenotypes is important for our understanding of the causation of psychiatric disorders. However, there are complexities associated with the assessment of environmental influences on behavior.

Methods/Principal Findings

We conducted a series of analyses using a prospective, longitudinal study of a nationally representative birth cohort from Finland (the Northern Finland 1966 Birth Cohort). Participants included a total of 3,761 male and female cohort members who were living in Finland at the age of 16 years and who had complete temperament scores. Our initial analyses (Wessman et al., in press) provide evidence in support of four stable and robust temperament clusters. Using these temperament clusters, as well as independent temperament dimensions for comparison, we conducted a data-driven analysis to assess the influence of a broad set of life course measures, assessed pre-natally, in infancy, and during adolescence, on adult temperament.

Results

Measures of early environment, neurobehavioral development, and adolescent behavior significantly predict adult temperament, classified by both cluster membership and temperament dimensions. Specifically, our results suggest that a relatively consistent set of life course measures are associated with adult temperament profiles, including maternal education, characteristics of the family’s location and residence, adolescent academic performance, and adolescent smoking.

Conclusions

Our finding that a consistent set of life course measures predict temperament clusters indicate that these clusters represent distinct developmental temperament trajectories and that information about a subset of life course measures has implications for adult health outcomes.

How can peer group influence the behavior of adolescents: explanatory model

The current work aims to study both the peer group and family influence on adolescent behaviour. In order to achieve the aforementioned objective, an explanatory model based on the Structural Equations Modelling (SEM) was proposed. The sample used was the group of adolescents that participated in the Portuguese survey of the European study Health Behaviour in School-aged Children (HBSC). The Portuguese survey included students from grades 6, 8 and 10 within the public education system, with an average age of 14 years old (SD=1.89). The total sample of the HBSC study carried out in 2006 was 4,877; however with the use of the SEM, 1,238 participants were lost out of the total sample. The results show that peers have a direct influence in adolescents' risk behaviours. The relationship with parents did not demonstrate the expected mediation effect, with the exception of the following elements: relation between type of friends and risk behaviour; and communication with parent and lesser involvement in violence behaviours and increased well-being. The negative influence of the peer group is more connected to the involvement in risk behaviours, whilst the positive influence is more connected with protective behaviours.

Developmental trajectories of child to adolescent externalizing behavior and adult DSM-IV disorder: results of a 24-year longitudinal study

OBJECTIVE

Childhood externalizing behavior is found to be relatively persistent. Developmental pathways within types of externalizing behavior have been recognized from childhood to adolescence. We aimed to describe the prediction of adult DSM-IV disorders from developmental trajectories of externalizing behavior over a period of 24 years on a longitudinal multiple birth cohort study of 2,076 children. This has not been examined yet.

METHODS

Trajectories of the four externalizing behavior types aggression, opposition, property violations, and status violations were determined separately through latent class growth analysis (LCGA) using data of five waves, covering ages 4-18 years. Psychiatric disorders of 1,399 adults were assessed with the CIDI. We used regression analyses to determine the associations between children's trajectories and adults' psychiatric disorders.

RESULTS

All externalizing behavior types showed significant associations with disruptive disorder in adulthood. In all antisocial behavior types high-level trajectories showed the highest probability for predicting adult disorders. Particularly the status violations cluster predicted many disorders in adulthood. The trajectories most often predicted disruptive disorders in adulthood, but predicted also anxiety, mood, and substance use disorders.

CONCLUSIONS

We can conclude that an elevated level of externalizing behavior in childhood has impact on the long-term outcome, regardless of the developmental course of externalizing behavior. Furthermore, different types of externalizing behavior (i.e., aggression, opposition, property violations, and status violations) were related to different adult outcomes, and children and adolescents with externalizing behavior of the status violations subtype were most likely to be affected in adulthood.

Early trajectories of interparental conflict and externalizing problems as predictors of social competence in preadolescence

Consistent with developmental cascade notions, the present study investigated (a) associations between trajectories of interparental conflict and early externalizing problems during childhood and (b) early trajectories of externalizing problems as a pathway by which interparental conflict impacts children's social competence in preadolescence. Participants were 235 children and their parents and teachers. Children were assessed annually for 3 years, beginning when they were in kindergarten. Parents provided reports of interparental conflict and child externalizing problems. Children's social competence (prosocial behavior, social problems) was assessed approximately 5 years later via parent and teacher reports. Results from parallel process models indicated that changes in interparental conflict were positively associated with changes in externalizing problems during childhood. Further, demonstrating pathways consistent with notions of developmental cascades, early trajectories of externalizing problems accounted for the longitudinal link between early trajectories of interparental conflict and children's social problems in preadolescence.

Predicting adult emotional and behavioral problems from externalizing problem trajectories in a 24-year longitudinal study

The aim of this study was to examine the prediction of adult behavioral and emotional problems from developmental trajectories of externalizing behavior in a 24-years longitudinal population-based study of 2,076 children. The adult psychiatric outcome of these trajectories has not yet been examined. Trajectories of the four externalizing behavior types: aggression, opposition, property violations and status violations were determined separately through latent class growth analysis using data of five waves, covering ages 4-18 years. We used regression analyses to determine the associations between children's trajectories and adults' psychiatric problems based on the Adult Self-Report. The developmental trajectories of the four types of externalizing behavior mostly predicted intrusive, aggressive and rule-breaking behavior in adulthood. Non-destructive behaviors in childhood such as opposition and status violations predict adult problems to a larger extent than destructive behaviors such as aggression and property violations. In general, children who develop through high-level trajectories are likely to suffer from both internalizing and externalizing problem behavior in adulthood, regardless the direction of change (i.e. increasing/decreasing/persisting) of the high-level trajectory. We can conclude that the level rather than the developmental change of externalizing behavior problems has a larger impact on adult outcome.

Trajectories of positive and negative behaviors from early- to middle-adolescence

Although the positive youth development (PYD) model initially assumed inverse links between indicators of PYD and of risk/problem behaviors, empirical work in adolescence has suggested that more complex associations exist between trajectories of the two domains of functioning. To clarify the PYD model, this study assessed intraindividual change in positive and problematic indicators across Grades 5-10, and the links between these trajectories of development, among 2,516 participants from the 4-H Study of PYD (58.1% females; 64.9% European American, 7.0% African American, 12.3% Latino/a American, 2.6% Asian American or Pacific Islander, 1.8% Native American, 3.0% multiethnic-racial, and 8.4% with inconsistent race/ethnicity across waves). Results from person-centered analyses indicated that most youth clustered in the high trajectories of positive indicators and in the low trajectories of the negative ones. Consistent with past research, overlap between trajectories of positive and negative behaviors was found. These results suggest that theory and application need to accommodate to variation in the links between positive and problematic developmental trajectories.

Pathways and Predictors of Antisocial Behaviors in African American Adolescents from Poor Neighborhoods

Antisocial behavior among youth remains a serious personal and social problem in the United States. The purposes of this study were to (1) identify the shape and number of developmental trajectories of antisocial behavior in a sample of poor, inner-city African American youth, and (2) test predictors of group membership and the developmental course of antisocial behaviors. Using growth mixture modeling, we examined predictors of antisocial behavior pathways and the likelihood of arrest in a sample of 566 poor, urban African American adolescents (ages 11 to 16). Three distinct trajectory classes of antisocial behavior were identified over a period of six years: one low-risk group (low steady) and two high-risk groups (incremental and high starter). The conditional probabilities for being arrested during ages 14-16 were 0.18 for the low steady class, 0.68 for the incremental class, and 0.31 for high starter class. Prevention strategies for adolescents at high risk are discussed.
