Association Between Early Onset of Gambling Participation and Substance Use in Preadolescents and Age-17 Frequency and Characteristics of Addictive Behaviors
This study examined the specific and potential joint contribution of early onset of gambling participation (GP) and substance use (SU) in preadolescence to the frequency and characteristics of both behaviors in late adolescence, while controlling for confounders. Participants ( N = 1,270; 51.2% boys) were part of a Canadian birth cohort. Age 10–12 years self-reports of GP and SU over the past year (collected 2007–2009) were used to identify pread…
Peer victimization in college: The role of gendered personality traits and previous peer victimization experiences
This study examined the association of masculine and feminine personality traits with peer victimization in college and the moderating role of previous peer victimization experiences. Using a longitudinal sample of 716 participants (58% women), victimization in childhood and adolescence was assessed through peer- and self-reports. At age 19, participants evaluated their victimization in college and gendered personality traits. Control variables i…
Social support moderates the link between chronic peer victimization in school and later cortisol secretion
Using a genetically informed design based on twins, this study tested the association between chronic peer victimization from ages 12 to 17 and later cortisol secretion at age 19 and the moderating effect of social support in this regard. These associations were examined while also considering the effects of genetic factors and concurrent victimization experiences at age 19. Participants (148 monozygotic [MZ] and 227 dizygotic [DZ] twin pairs; 56…
Reciprocal associations between teachers' use of disciplinary practices and aggression in elementary school students
Transactional theories of human development suggest that the association between teachers' disciplinary practices and students' aggressive behavior may be reciprocal. However, no study has tested this possibility. Therefore, this study examines reciprocal associations between teachers' use of disciplinary practices (educational and punitive) and aggressive behaviors in elementary school students. A sample comprising 1038 students (62 % boys) was …
Evaluating the Impact of the How‐to Parenting Program on Child Mental Health: A Randomized Controlled Trial in Grade Schools
The How‐to Parenting Program teaches parents how to provide autonomy support, structure, and affiliation, the three components of the parenting style shown to be beneficial for children's mental health. Using a waitlist RCT, we assessed its impact on school‐aged children's externalizing and internalizing problems. We also tested whether family composition, participating parents' gender, child age, sex, and baseline mental health modified its effe…
Academic Achievement, Externalizing Problems, and Close Friends in Middle School: Testing a Developmental Cascade Model Leading to Educational Attainment in the Late Twenties
Gene–environment interplay linking friends’ antisociality with different developmental trajectories of antisocial behavior during adolescence
This study investigated gene-environment correlations and interactions underlying the association between distinct developmental trajectories of adolescents' antisocial behavior and their friends' antisociality. Participants were 398 twin pairs (53% girls; 87% European descent) followed from age 13 to 19 years. Self-reported antisocial behavior was obtained from the twins and from their friends. Latent class growth modeling identified three antis…
Preadolescent individual, familial, and social risk factors associated with longitudinal patterns of adolescent alcohol, cannabis, and other illicit drug use in a population-representative cohort
The aim of this exploratory study was to identify developmental patterns of adolescent concurrent alcohol, cannabis, and other illicit drug use and their preadolescent individual, familial, and social risk factors in a population-representative cohort from the province of Quebec, Canada ( N = 1,593; 48.4% male). Age 12-17 years self-reports of alcohol, cannabis, and other illicit drug use were collected. Latent growth modeling was used to analyze…
The mediation role of reading-related endophenotypes in the gene-to-reading pathway
Although individual differences in reading-related skills are largely influenced by genetic variation, the molecular basis of the heritability of this phenotype is far from understood. Functional single-nucleotide polymorphisms spanning reading-candidate genes and genome-wide significant top hits were identified. By using a multiple-predictor/multiple-mediator framework, we investigated whether relationships between functional genetic variants (D…
The role of friends in the development of children’s classroom behavioral engagement and peer acceptance in kindergarten: A dyadic approach
Concurrent and prospective associations between family socioeconomic status, social support and salivary diurnal and hair cortisol in adolescence
BACKGROUND: Exposure to socioeconomic adversity is hypothesized to impact hypothalamic-pituitary-adrenal (HPA) axis activity and cortisol secretion, but existing evidence is inconsistent. Yet, few studies have investigated this association using a developmental approach that considers potential protective contextual factors. This study examined the role of stability and changes in family socioeconomic status (SES) in the prediction of multiple co…
Childhood behavior problems and adverse economic outcomes: A 30‐year population‐based study of intergenerational income mobility
BACKGROUND: The objectives of this study were to (a) assess the associations between early behavioral problems and intergenerational income mobility (i.e., the degree to which income status is transmitted from one generation to the next), (b) verify whether these associations are moderated by child sex, and (c) explore indirect effects of early behavioral problems on income mobility via high school graduation. METHODS: Data were drawn from the Qu…
Mechanisms and pathways linking kindergarten behavior problems with mid-life employment earnings for males from low-income neighborhoods
Childhood behavior problems are associated with reduced labor market participation and lower earnings in adulthood, but little is known about the pathways and mechanisms that explain these associations. Drawing on a 33-year prospective birth cohort of White males from low-income backgrounds (n = 1040), we conducted a path analysis linking participants' teacher-rated behavior problems at age 6 years—that is, inattention, hyperactivity, aggression-…
Reconsidering the failure model: Using a genetically controlled design to assess the spread of problems from reactive aggression to internalizing symptoms through peer rejection across the primary sch…
According to the failure model (Patterson & Capaldi, 1990), peer rejection is the intermediary link between problem behaviors and internalizing symptoms. The present study tested the model with 464 monozygotic and same-sex dizygotic twin pairs (234 female, 230 male dyads). Teacher-reported reactive aggression and internalizing symptoms, and peer-reported peer rejection were collected at ages 6, 7, and 10 (from 2001 to 2008). Support for the failu…
Association between developmental patterns of single and concurrent externalizing behaviors and internalizing problems over the preschool years
The present study investigated whether distinct developmental patterns of externalizing behaviors (EBs: hyperactivity-impulsivity, noncompliance, physical aggression) based on parent reports were repeatedly and differentially associated with separate dimensions of internalizing problems such as general anxiety, separation anxiety, and depressive symptoms across the early, middle, and late preschool years in a population birth cohort ( N = 2,057, …
Sports Attitudes in Childhood and Income in Adulthood
Research shows that sports participation in youth is associated with earnings in adulthood. However, studies have often relied on self-reported earnings and on single indicators of sports participation. Using large-scale data linked to administrative records, we investigate: (a) whether sports attitudes at age 13 are uniquely related to income at ages 30–36 and (b) whether educational attainment and mental health in early adulthood mediate this a…

Link Between Peer Victimization in College and Cortisol Secretion: Roles of Genetic Vulnerabilities and Social Support
Teachers' behaviour and children's academic achievement: Evidence of gene–environment interactions
BACKGROUND: Children's academic achievement is considerably influenced by genetic factors, which rarely operate independently of environmental influences such as teachers' behaviour. Praise and punitive discipline are commonly used management strategies by teachers. However, their effects on the genetic expression of children's academic achievement are still unclear. AIMS: This study examined potential gene-environment interactions in the associa…
Classroom Placement and Twins’ Social Behaviors in Elementary School: Providing Empirical Evidence to Inform Educational Policy
Classroom placement of twins is an ongoing issue for educational policy. Many educational jurisdictions have standard policy most commonly founded in the belief that separation supports individual identity, personal development and academic opportunity. This study examined the effects of classroom placement in a sample of 560 twin pairs whose behaviors were assessed from ages 5 to 12 years. We found no detrimental effect of classroom sharing on t…
The interchangeability of liking and friend nominations to measure peer acceptance and friendship
Two studies examine the convergence between measures of friendship and measures of liking in the assessment of friendship and peer acceptance. In the first study, 551 (301 boys and 250 girls) Canadian primary school children (ages 8–11) nominated friends and liked-most classmates. In the second study, 282 (127 boys and 155 girls) US primary school children (ages 9–11) nominated friends and rated classmates on a sociometric preference scale. The r…
Interplay between peer experiences and classroom behavioral engagement throughout early childhood: Intraindividual and interindividual differences
The Intensity of Formal Child-Care Attendance Decreases the Shared Environment Contribution to School Readiness: A Twin Study
The purpose of this study was to explore if child-care intensity (hours/weeks) and age of onset could moderate genetic and environmental contributions to school readiness. A sample of 648 (85% Whites; 50% Females) pairs of twins was used to compute a GxE, CxE and ExE interaction analyses. The moderation model showed that shared environment explains 48% of individual differences in school readiness for children not attending formal child-care, and…
Academic Achievement in Grades 1 to 6: Association with Child, Parental and Socio-Familial Characteristics 5 Months After Birth
Early risk factors associated with preschool developmental patterns of single and co-occurrent disruptive behaviors in a population sample
The present study investigated prenatal and early postnatal risk factors associated with developmental patterns of disruptive behaviors (DBs; e.g., hyperactivity-impulsivity, noncompliance, physical aggression) from ages 1.5 to 5 years in a population birth cohort ( N = 2,057; 50.7% boys). Six high-trajectory classes obtained by latent growth modeling were used as longitudinal indicators of single-DB and co-occurrent DBs. Children following low o…
Developmental trajectories of childhood disruptive behaviors and adolescent delinquency: A six-site, cross-national study
This study used data from 6 sites and 3 countries to examine the developmental course of physical aggression in childhood and to analyze its linkage to violent and nonviolent offending outcomes in adolescence. The results indicate that among boys there is continuity in problem behavior from childhood to adolescence and that such continuity is especially acute when early problem behavior takes the form of physical aggression. Chronic physical aggr…
The power of friendship: Protection against an escalating cycle of peer victimization
Trajectories of Prosocial Behavior and Physical Aggression in Middle Childhood: Links to Adolescent School Dropout and Physical Violence
Trajectories of prosocial behavior and physical aggression between 6 and 12 years of age were identified for a sample ( N =1,025) of males. The trajectories were then used to predict school dropout and physical violence at age 17. Using a group‐based semi‐parametric method, two trajectories of prosociality (low and moderate declining) and three trajectories of physical aggression (low, moderate, and high declining) were obtained. Only a small min…
Transactional analysis of the reciprocal links between peer experiences and academic achievement from middle childhood to early adolescence
This study tested a transactional model of reciprocal influences regarding students' peer experiences (peer acceptance, peer rejection, and friends' academic achievement) and students' academic achievement from middle childhood to early adolescence. This longitudinal model was tested on 452 students (198 girls), mostly Caucasian and French speaking, who were assessed yearly from Grades 2 through 7. Structural equation models revealed that, for bo…
Deviant Friends and Early Adolescents' Emotional and Behavioral Adjustment
This study investigated whether friendships with deviant peers, in addition to being related to adolescents' behavioral adjustment problems, would also be negatively related to adolescents' emotional adjustment. Three hundred five adolescents who had either no mutual friends, nondeviant friends, or deviant friends were compared, with respect to their levels of delinquent behavior, depression, and loneliness at age 13. As expected, adolescents wit…
Neighborhood Processes, Self-Efficacy, and Adolescent Mental Health
Self-efficacy beliefs are central to mental health. Because adolescents' neighborhoods shape opportunities for experiences of control, predictability, and safety, we propose that neighborhood conditions are associated with adolescents' self-efficacy and, in turn, their internalizing problems (i.e., depression/anxiety symptoms). We tested these hypotheses using three waves of data from the Project on Human Development in Chicago Neighborhoods ( N …
Developmental profiles of peer social preference over the course of elementary school: Associations with trajectories of externalizing and internalizing behavior
Using a new longitudinal clustering technique, this study aimed to (a) empirically identify groups of children with distinct longitudinal profiles of peer social preference during elementary school; (b) compare these groups regarding their longitudinal pattern of classification into J. D. Coie, K. A. Dodge, and H. Coppotelli's (CDC; 1982) sociometric categories; and (c) compare these groups regarding their longitudinal trajectories of antisocial,…
Personal and familial predictors of peer victimization trajectories from primary to secondary school
Using a sample of 767 children (403 girls, 364 boys), this study aimed to (a) identify groups with distinct trajectories of peer victimization over a 6-year period from primary school through the transition to secondary school, and (b) examine the associated personal (i.e., aggression or internalizing problems) and familial (family status, socioeconomic status, the parent-child relationship) predictors. Peer victimization was assessed via self-re…
Rough-and-Tumble Play and the Development of Physical Aggression and Emotion Regulation: A Five-Year Follow-Up Study
The Road to Gang Membership: Characteristics of Male Gang and Nongang Members from Ages 10 to 14
This study examined the stability of belonging to a gang in early adolescence, the behaviour profiles, family characteristics, and friendships of nongang and gang members. The subjects in the present study were originally part of a larger sample of boys. One hundred and forty‐two boys who had a complete data set at ages 11, 12, 13, and 14 were selected for the present study. Loglinear analyses indicated that gang membership was stable from ages 1…
Risk Factor Models for Adolescent Verbal and Physical Aggression Toward Fathers
Parent and Peer Effects on Delinquency‐related Violence and Dating Violence: A Test of Two Mediational Models
Drawing on two complementary process models of violence, i.e., social cognitive theory and rejection sensitivity theory, the goal of the present study was (1) to examine the unique effects of parents and peers on boys’ violent behavior in delinquency‐related contexts and in dating relationships, (2) to assess the mediating processes underlying these links, and (3) to test whether these processes operate in the same way for delinquency‐related vio…
Stability and Variability of Adolescents’ Affiliation with Delinquent Friends: Predictors and Consequences
The effects of stability versus change in adolescents’ affiliation with delinquent or nondelinquent friends over a two‐year period (T1–T2) on delinquent behavior one year later (T3) were examined. In addition, T1 predictors of stability and change in the affiliation with delinquent or nondelinquent friends from T1 to T2 were assessed. Participants were 152 adolescents (77 girls, mean age 12.1 years at T1). Friends’ delinquent behavior was assesse…
Relations between Theory of Mind and Indirect and Physical Aggression in Kindergarten: Evidence of the Moderating Role of Prosocial Behaviors
The present study examined the association between theory of mind and indirect versus physical aggression, as well as the potential moderating role of prosocial behavior in this context. Participants were 399 twins and singletons drawn from two longitudinal studies in Canada. At five years of age, children completed a theory of mind task and a receptive vocabulary task. A year later, teachers evaluated children's indirect and physical aggression …
Examining genetic and environmental effects on reactive versus proactive aggression
This study compared the contribution of genes and environment to teacher-rated reactive and proactive aggression in 6-year-old twin pairs (172 pairs: 55 monozygotic girls, 48 monozygotic boys, 33 dizygotic girls, 36 dizygotic boys). Genetic effects accounted for 39% of the variance of reactive aggression and for 41% of the variance of proactive aggression. The remainder of the variance was explained by unique environmental effects. Genetic as wel…
Friendship conflict and the development of generalized physical aggression in the early school years: A genetically informed study of potential moderators
Several authors consider high and frequent conflicts between friends during childhood as a serious risk for subsequent conduct problems such as generalized physical aggression toward others (e.g., Kupersmidt, Burchinal, & Patterson, 1995; Sebanc, 2003). Although it seems logical to assume that friendship conflict could have some negative consequences on children's behaviors, some scholars have suggested that a certain amount of conflict between f…

The moderating role of peer norms in the associations of social withdrawal and aggression with peer victimization
This study examined the moderating role of classroom injunctive norms salience regarding social withdrawal and regarding aggression in the longitudinal association between these behaviors and peer victimization. A total of 1,769 fourth through sixth graders (895 girls, M = 10.25 years, SD = 1.03) from 23 schools (67 classrooms) completed a peer nomination inventory in the fall (T1) and spring (T2) of the same academic year. Participants circled t…
Do peer group norms moderate the expression of genetic risk for aggression
Do other people's plights matter? A genetically informed twin study of the role of social context in the link between peer victimization and children's aggression and depression symptoms
Using a genetically informed design, this study examined the additive and interactive effects of genetic risk, personal peer victimization experiences, and peer victimization experienced by others on children's aggression and depression symptoms. Of major interest was whether these effects varied depending on whether or not the victimized others were children's close friends. The sample comprised 197 monozygotic and same-sex dizygotic twin pairs …
Links between friendship relations and early adolescents’ trajectories of depressed mood
The present study examined to what extent different types of friendship experiences (i.e., friendlessness, having depressed friends, and having nondepressed friends) are associated with early adolescents' longitudinal trajectories of depressed mood. On the basis of a sample of 201 youths (108 girls, 93 boys), we identified 3 distinct longitudinal profiles of depressed mood from Grade 5 (age 11) through Grade 7 (age 13): one group with consistentl…
Patterns of Affiliation with Delinquent Friends During Late Childhood and Early Adolescence: Correlates and Consequences
This study examined longitudinal patterns of affiliation with delinquent friends during late childhood and early adolescence, i.e., from ages 10 through 13, in a sample of 376 participants of both genders. Four groups with distinct affiliation profiles were found: an early affiliative group, a late affiliative group, a declining group (i.e., a group that affiliates with delinquent friends early on but much less so thereafter), and a group of chil…
The role of maternal educational aspirations in mediating the risk of income source on academic failure in children from persistently poor families
Affiliation with Delinquent Friends: Contributions of Parents, Self-Esteem, Delinquent Behavior, and Rejection by Peers
Examined in this study was whether a perceived lack of closeness with parents (a) would be related indirectly to early adolescents' association with delinquent friends and (b)would be mediated by a lack of self-esteem. The mediated relation, however, was expected to hold only for (a) delinquent early adolescents who might be attracted to delinquent friends because of the similarity of behavioral characteristics or (b) early adolescents who are re…
Predictive and Concurrent Correlates of Gambling in Early Adolescent Boys
This study had two objectives: (a) to identify a link between gambling, delinquency, and substance use in a sample of early adolescent males and (b) to verify if behavioral precursors of gambling are similar to behavioral precursors of delinquency and substance use. Results indicated a concurrent link between gambling, delinquency, and substance use. They also revealed that low anxiety/withdrawal at 10 and 11 years of age predicted, although mode…
Affiliation with Delinquent Friends: Contributions of Parents, Self-Esteem, Delinquent Behavior, and Rejection by Peers
Examined in this study was whether a perceived lack of closeness with parents (a) would be related indirectly to early adolescents' association with delinquent friends and (b)would be mediated by a lack of self-esteem. The mediated relation, however, was expected to hold only for (a) delinquent early adolescents who might be attracted to delinquent friends because of the similarity of behavioral characteristics or (b) early adolescents who are re…
Does Preschool Help Prevent Delinquency in Boys With a History of Perinatal Complications
We examined whether a preschool intervention program moderates the effects of perinatal complications with a sample of boys from the most disadvantaged areas of Montreal (Canada). Some boys experienced the preschool program and some did not, which allowed us to test whether the program had any effects on the boys' risk for early adolescent delinquency given their perinatal histories. We hypothesized that perinatal complications would place boys a…
Effects of Friends’ Characteristics on Children’s Social Cognitions
Based on the notion that friends play a fundamental role in children’s social cognitive development, the study investigates the relation between friends’ characteristics (i.e., aggressiveness and prosociality) and children’s interpretation of social cues and generation of responses in hypothetical provocation situations. The study was conducted with a sample of 322 children (155 boys, 167 girls) from first through sixth grade. The results showed …
The power of friendship: Protection against an escalating cycle of peer victimization
Early parental separation and the psychosocial development of daughters 6-9 years old
The relationship of timing of early parental separation to psychosocial development of daughters was examined in 77 girls, 6-9 years of age over a four-year period. Disruptive behavior across contexts was prevalent in girls separated between birth and two years of age. Girls separated between three and five years of age showed more externalizing behavior problems, but only in school. Results suggest that early parental separation has more pervasi…
