ABSTRACT
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, 50.7% boys). Six high trajectory classes obtained by latent growth modeling were used as longitudinal indicators of single EB and co-occurrent EBs. Children following low or moderate trajectories for all EBs served as the reference class. Results revealed that children in trajectory classes reflecting high levels of co-occurring EBs showed higher levels of general anxiety, separation anxiety, and depressive symptoms across the preschool years. In contrast, children in trajectory classes reflecting single EB manifested higher levels of some, but not all, dimensions of internalizing problems. In addition, their scores varied from one period to another. No sex differences were observed in the above associations. These results underline the need for comprehensive assessments across distinct types of EBs and internalizing problems to better reflect the characteristics that distinguish individual children. Finally, results suggest that children showing early co-occurrent EBs and internalizing symptoms may be an important group to target for in-depth assessment and possibly preventive intervention.

The developmental association between disruptive behaviors (DBs: hyperactivity-impulsivity, non-compliance, physical aggression) and internalizing problems in early childhood is not well understood and has generated competing hypotheses and mixed results. Using a person-centered strategy, the present study aimed to examine concurrent trajectories of DBs and trajectories of internalizing problems from age 1.5 to 5 years in a population-representative sample (N = 2057; 50.7% boys). Six trajectories of DBs and three trajectories of internalizing problems, based on parent reports and obtained via latent growth modeling across five periods of assessment, were used as longitudinal indicators of each type of behaviors. Children following low or moderate trajectories served as the reference class. Compared to children in the reference class, those in trajectory classes characterized by high levels of co-occurring DBs (OR = 6.60) and, to a lesser extent, those in single high DB classes (OR = 2.78) were more likely to follow a high trajectory of internalizing problems simultaneously. These results support a multiple problem hypothesis regarding the association between DBs and internalizing problems, consistent with a developmental perspective that includes a general factor underpinning different psychopathologies. These findings highlight the importance of considering the co-occurrence between DBs and internalizing problems when studying either construct in children.
ABSTRACT
PURPOSE: Inconsistent reports raise the question of the extent to which poor adult outcomes are associated with adolescent polysubstance use (PSU: alcohol, marijuana, other illicit drugs) above and beyond earlier risk factors. METHODS: Early adulthood substance-related and psychosocial outcomes were examined in association with age 13 to 17 developmental patterns of PSU in boys from urban, low SES neighborhoods (N = 926). Three classes obtained by latent growth modeling described low/non-users (N = 565, 61.0%), lower risk PSU (later onset, occasional use, 2 ≤ substances; N = 223, 24.1%), and higher risk PSU (earlier onset, frequent use, 3 ≥ substances; N = 138, 14.9%). Preadolescent individual, familial and social predictors of adolescent PSU patterns were used as covariates. RESULTS: Adolescent PSU contributed to both age-24 substance-related outcomes (frequency of alcohol, drug use, and getting drunk, risky behaviors under influence, and use-related problems) and psychosocial outcomes (no high school diploma, professional or financial strain, ASP symptoms, criminal record) over and above preadolescent risk factors. Controlling for preadolescent risk factors, adolescent PSU made a more important contribution to adult substance use outcomes (increasing the risk by about 110%) than to psychosocial outcomes (16.8% risk increase). PSU classes showed poorer adjustment for all age-24 substance use, and for various psychosocial outcomes than low/non-users. Higher risk polysubstance users also reported poorer outcomes than their lower risk peers for most substance use outcomes, and for professional or financial strain and criminal record. CONCLUSION: Findings highlight the contribution of adolescent PSU in a dose-response fashion, over and above preadolescent risk factors, on both homotypic and heterotypic outcomes in early adulthood.

This study investigated adolescents' single and co-occurring developmental patterns of gambling participation and substance use and their association with gambling and substance use-related issues at age 17, controlling for confounders. Multiple assessments from age 12 to 17 were conducted in a population-based cohort (N=1594, 51.2% boys). Latent growth modeling was used to analyze developmental patterns and Generalized linear models to examine their association with age-17 gambling and substance use-related problems, types and variety of activities, and substance abuse. Results revealed six developmental patterns, including Low- or Non-substance Users or Gamblers (24.2% sample), two trajectory-classes of Later-Onset Increasing (to a moderate level) substance users, either with or without gambling participation (7.8% and 45.5%, respectively), two trajectory-classes of Early-Onset Increasing (to a higher level) substance users, either with or without gambling participation (6.2% and 12.7%, respectively), and a smaller trajectory-class of Slow-Increasing Substance Users and Early-Onset Gamblers, declining to non-gambling after age 13 (3.6%). Gambling participation and substance use did not appear to influence each other with regard to their onset and course throughout adolescence, and to age-17 types and variety of gambling activities or substances used, problems related to gambling participation or substance use, or substance abuse. These findings are consistent with the addictive syndrome model and with both common and individualized approaches to prevention and treatment for adolescent gamblers or substance users.

The present study documented in two distinct population-based samples the contribution of preschool fluid and crystallized cognitive abilities to school achievement in primary school and examined the mediating role of crystallized abilities in this sequence of predictive associations. In both samples, participants were assessed on the same cognitive abilities at 63 months (sample 1, n = 1072), and at 41 and 73 months (sample 2, n = 1583), and then with respect to their school achievement from grade 1 (7 years) to grade 6 (12 years). Preschool crystallized abilities were found to play a key role in predicting school achievement. They contributed substantially to school achievement in the early school years, but more modestly in the later years, due to the strong auto-regression of school achievement. They also mediated the association between fluid abilities and later school achievement in the early grades of school, with the former having modest direct contribution to the latter in the later grades. These findings are discussed regarding their implication for preventive interventions.

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 or moderate trajectories for all DBs served as the reference class. Results showed low commonality of risk factors among single-DB trajectory classes, suggesting that "pure" forms of DBs have specific etiologies. In contrast, the trajectory classes with a high DB in common shared 20.0% to 46.7% of their risk factors. Overall, 40.0% of significant risk factors across trajectory classes were common to between two and four classes, whereas 60.0% of the significant risk factors were specific to one class or another. However, risk factors common among classes accounted for the greater part (63.2%) of the associations, especially in co-occurrent DBs trajectory classes. These risk factors included male sex, a higher number of siblings, maternal symptoms of depression and conduct problems, young motherhood, lack of positive parenting, family dysfunction, and lower socioeconomic status. Children thus develop early distinct patterns of DBs associated with both common and specific prenatal and early postnatal risk factors. Longitudinal assessments of early manifestations of DB, including a range of behaviors and a variety of potential risk factors to reflect the distinctiveness of children and their families, could help guide etiological research, tailor early interventions, and prevent a cascade of deleterious influences and outcomes.

This study examined developmental patterns of co-occurrent alcohol, marijuana, and other illicit drugs use during adolescence and the associated preadolescent risk factors in a longitudinal sample of 926 boys from low-socioeconomic, urban neighborhoods. Latent growth mixture modeling revealed six developmental patterns: non-/low-alcohol and non-illicit drug users (61% sample) and five polysubstance user-groups varying in severity based on onset, frequency and type of substances used. In comparisons with non-/low-users, several preadolescent risk factors were associated with increasing severity of polysubstance use. Higher sensation-seeking and lower anxiety were associated with all user-groups. Low self-esteem and family-related risk factors differentiated all user-groups from later-onset users. Higher impulsivity and school problems characterized early-onset and frequent polysubstance users. Impulsive sensation-seekers with lower anxiety and self-esteem cumulated a larger number and higher severity of risk factors and were at risk of early-onset frequent polysubstance use, emphasising the importance of indicated prevention for these high-risk boys.

Past studies have identified various risk and protective factors for problem gambling (PG). However, no study has examined the interplay between these factors using a combination of person-centered and variable-centered approaches embedded within a longitudinal design. The present study aimed to (a) identify distinct profiles in early adolescence based on a set of risk factors commonly associated with PG (impulsivity, depression, anxiety, drug-alcohol use, aggressiveness, and antisociality), (b) explore the difference in reported gambling problems between these profiles during midadolescence and early adulthood, and (c) identify family- and peer-related variables that could operate as protective or compensatory factors in this context. Two samples were used: (a) a population sample (N = 1,033) living in low socioeconomic-status neighborhoods and (b) a population sample (N = 3,017) representative of students attending Quebec schools. Latent profile analyses were conducted to identify at-risk profiles based on individual risk factors measured at age 12 years. Negative binomial regression models were estimated to compare profiles in terms of their reported gambling problems at ages 16 and 23. Finally, family- and peer-related variables measured at age 14 were included to test their protective or compensatory role with respect to the link between at-risk profiles and gambling problems. Four profiles were identified: well-adjusted, internalizing, externalizing, and comorbid. Compared to the well-adjusted profile, the externalizing and comorbid profiles reported more gambling problems at ages 16 and 23, but the internalizing profile did not differ significantly. Various protective and compensatory factors emerged for each profile at both time points. (PsycINFO Database Record

Despite the well-established association between problem gambling and ADHD core categories of impulsivity-hyperactivity and inattention, the link between parents' problem gambling and impulsivity-hyperactivity/inattention (IH/I) behaviors in children has not been investigated. This study investigated the association between parents' problem gambling and children's IH/I behaviors while controlling for potential confounding variables. A population-based prospective cohort followed-up from kindergarten to age 30, the Quebec Longitudinal Study of Kindergarten Children (QLSKC), provided data over three generations. Among 1358 participants at age 30, parents with a child aged 1 year or older (N = 468; Mean age = 4.65 years; SD = 2.70) were selected. Generalized Linear Models included measures of grandparents' and parents' problem gambling, parents' IH/I behaviors in childhood, and a host of risk factors and comorbidities to predict IH/I in children. Intergenerational bivariate associations were observed between grandparents' problem gambling, parents' IH/I in childhood and problem gambling at age 30, and between parents' IH/I, problem gambling, and children's IH/I behaviors. Parents' problem gambling predicted children's IH/I behaviors above and beyond the effects of covariates such as family and socioeconomic characteristics, alcohol and drug use, depression symptoms and parents' gambling involvement. Parents' IH/I behaviors in childhood also predicted children's IH/I and had a moderating, enhancing effect on parents' problem gambling association with their offspring's IH/I behaviors. Problem gambling is a characteristic of parents' mental health that is distinctively associated with children's IH/I behaviors, above and beyond parents' own history of IH/I and of typically related addictive, psychopathological or socioeconomic risk factors and comorbidities.

The pathways model of problem gambling suggests the existence of three developmental pathways to problem gambling, each differentiated by a set of predisposing biopsychosocial characteristics: behaviorally conditioned (BC), emotionally vulnerable (EV), and biologically vulnerable (BV) gamblers. This study examined the empirical validity of the Pathways Model among adolescents followed up to early adulthood. A prospective-longitudinal design was used, thus overcoming limitations of past studies that used concurrent or retrospective designs. Two samples were used: (1) a population sample of French-speaking adolescents (N = 1033) living in low socio-economic status (SES) neighborhoods from the Greater Region of Montreal (Quebec, Canada), and (2) a population sample of adolescents (N = 3017), representative of French-speaking students in Quebec. Only participants with at-risk or problem gambling by mid-adolescence or early adulthood were included in the main analysis (n = 180). Latent Profile Analyses were conducted to identify the optimal number of profiles, in accordance with participants' scores on a set of variables prescribed by the Pathways Model and measured during early adolescence: depression, anxiety, impulsivity, hyperactivity, antisocial/aggressive behavior, and drug problems. A four-profile model fit the data best. Three profiles differed from each other in ways consistent with the Pathways Model (i.e., BC, EV, and BV gamblers). A fourth profile emerged, resembling a combination of EV and BV gamblers. Four profiles of at-risk and problem gamblers were identified. Three of these profiles closely resemble those suggested by the Pathways Model.

In both adolescents and adults, gambling problems and depressive symptoms co-occur and share some common risk factors (e.g., impulsivity and socio-family risk). However, little is known about (1) the developmental course of the co-morbidity of these problems; (2) variables that may moderate the effect of these common risk factors on gambling problems and depressive symptoms. Of specific interest could be individuals' social relationships with significant others such as parents and friends, because research shows that they moderate the effect of other risk factors on gambling problems and depressive symptoms. The goals of this study were to: (a) identify developmental pathways for gambling problems and depressive symptoms, with a focus on co-morbidity; (b) assess the moderating effect of relationship quality with parents and friends on the link between common risk factors and the trajectories of gambling problems and depressive symptoms. Study participants were 878 males. Predictors were assessed during childhood and adolescence and gambling problems and depressive symptoms were assessed in late adolescence and young adulthood. Latent class analysis revealed four distinct joint trajectories of gambling problems and depressive symptoms. Subsequent logistic regression revealed that impulsivity predicted membership in all pathogenic trajectories, and quality of the relationship with parents predicted membership in depressogenic trajectories. In addition, we found that the membership in the comorbid trajectory can be predicted by an interaction between friendship quality and socio-family risk.

Comorbidity is frequent among disruptive behaviors (DB) and leads to mental health problems during adolescence and adulthood. However, the early developmental origins of this comorbidity have so far received little attention. This study investigated the developmental comorbidity of three DB categories during early childhood: hyperactivity-impulsivity, non-compliance, and physical aggression. Joint developmental trajectories of DB were identified based on annual mother interviews from age 1½ to 5 years, in a population-representative birth-cohort (N = 2045). A significant proportion of children (13 % to 21 %, depending on the type of DB) consistently displayed high levels of hyperactivity-impulsivity, non-compliance, or physical aggression from age 1½ to 5 years. Developmental comorbidity was frequent, especially for boys: 10 % of boys and 3.7 % of girls were on a stable trajectory with high levels of symptoms for the three categories of DB. Significant associations were observed between preschool joint-trajectories of DB and indicators of DB and school adjustment assessed by teachers in first grade. Preschoolers who maintained high levels of hyperactivity-impulsivity, non-compliance, and physical aggression, displayed the highest number of DB symptoms in first grade for all categories according to their teacher. They were also among the most disadvantaged of their class for school adjustment indicators. Thus, DB manifestations and developmental comorbidity of DB are highly prevalent in infancy. Early childhood appears to be a critical period to prevent persistent and comorbid DB that leads to impairment at the very beginning of school attendance and to long-term serious health and social adjustment problems.

BACKGROUND: The monoamine oxidase A (MAOA) gene has been shown to moderate the impact of maltreatment on antisocial behaviour. Replication efforts have, however, yielded inconsistent results. AIMS: To investigate whether the interaction between the MAOA gene and violence is present across the full distribution of violence or emerges at higher levels of exposure. METHOD: Participants were 327 male members of the Québec Longitudinal Study of Kindergarten Children. Exposure to violence comprised retrospective reports of mother's and father's maltreatment, sexual and physical abuse. Conduct disorder and antisocial personality symptoms were assessed in semi-structured interviews and partner violence, property-violent crimes and arrest were self-reported. RESULTS: Non-linear interactions between the MAOA gene and violence were detected, suggesting that the genetic moderation may come about once a certain level of violence is experienced. CONCLUSIONS: Future studies should investigate the mechanisms translating substantial violence exposure, which could, subsequently, trigger the expression of genetically based differences in antisocial behaviour.

AIMS: To estimate trajectories of gambling variety from mid-adolescence to age 30 years, and compare the different trajectory groups with regard to the type and the frequency of gambling activities practiced and gambling-related problems. DESIGN: Prospective longitudinal cohort study. SETTING: Province of Quebec, Canada. PARTICIPANTS: A mixed-gender general population cohort assessed at ages 15 (n=1882), 22 (n=1785) and 30 (n=1358). MEASUREMENTS: Adolescent and adult versions of the South Oaks Gambling Screen (SOGS). FINDINGS: Group-based trajectory analysis identified three distinct trajectories: a late-onset low trajectory (26.7% of sample) initiating gambling at age 22, an early-onset low trajectory (64.8% of sample), characterized by one to two different activities from age 15 onwards and a high trajectory (8.4% of sample), with an average of four to five different activities from age 15 to 30. Males (14.2%) were four times more likely to be on a high trajectory than females (3.5%) (P<0.001). Preferred types of gambling activities were similar across the three trajectories. Participants on a high trajectory reported higher gambling frequency at ages 15 and 30, and were more likely to experience problem gambling at age 30: 3.09 [95% confidence interval (CI)=1.66, 5.75] and 2.26 (95% CI=1.27, 4.04) times more, respectively, than late-onset low and early-onset low participants, even when socio-economic status (SES), frequency of gambling and problem gambling in adolescence, gender, age 30 education, SES and frequency of gambling were controlled. CONCLUSIONS: Engaging in several different types of gambling in early adulthood appears to be a risk factor for emergence of problem gambling.

Studies of gambling starting before adulthood in the general population are either cross-sectional, based on the stability of these behaviors between 2 time points, or cover a short developmental period. The present study aimed at investigating the developmental trajectories of gambling problems across 3 key periods of development, mid-adolescence, early adulthood, and age 30, in a mixed-gender cohort from the general population. Using a semiparametric mixture model, trajectories were computed based on self-reports collected at ages 15 (N = 1,882), 22 (N = 1,785), and 30 (N = 1,358). Two distinct trajectories were identified: 1 trajectory including males and females who were unlikely to have experienced gambling problems across the 15-year period, and 1 trajectory including participants likely to have experienced at least 1 problem over the last 12 months at each time of assessment. Participants following a high trajectory were predominantly male, participated frequently in 3 to 4 different gambling activities, and were more likely to report substance use and problems related to their alcohol and drug consumption at age 30. Thus, gambling problems in the general population are already observable at age 15 in a small group of individuals, who maintain some level of these problems through early adulthood, before moderately but significantly desisting by age 30, while also experiencing other addictive behaviors and related problems.

The Quebec Longitudinal Study of Kindergarten Children (QLSKC) is an ongoing population-based prospective longitudinal study presently spanning ages 6-29 years, designed to study the prevalence, risk factors, development and consequences of behavioural and emotional problems during elementary school. Kindergarten boys and girls attending French-speaking public schools in the Canadian province of Quebec during the 1986-87 and 1987-88 school years were included in the cohort: 2000 children representative of the population and 1017 children exhibiting disruptive behaviour problems. To date, 12 waves of data have been collected, and three generations of participants have been involved in the study (i.e. the study child, his parents and the first child of the study child). Information on demographics, psycho-social and lifestyle factors, child and family member characteristics (physical and mental health), and outcomes such as psychiatric diagnoses, delinquency or school diploma were assessed during three important developmental stages (childhood, adolescence and early adulthood). Blood samples were also collected in early adulthood for genetic analyses. Information on publications, available data and access to data can be found on the following website (http://www.gripinfo.ca/Grip/Public/www/).

OBJECTIVE: Literature clearly documents the association between mental health problems, particularly attention deficit hyperactivity disorder (ADHD), and educational attainment. However, inattention and hyperactivity are generally not considered independently from each other in prospective studies. The aim of the present study was to differentiate the unique, additive, or interactive contributions of inattention and hyperactivity symptoms to educational attainment. METHOD: The authors randomly selected 2,000 participants from a representative sample of Canadian children and estimated developmental trajectories of inattention and hyperactivity between the ages of 6 and 12 years using yearly assessments. High school graduation status, at age 22-23 years, was obtained from official records. RESULTS: Four trajectories of inattention and four trajectories of hyperactivity were observed between the ages of 6 and 12 years. After controlling for hyperactivity and other confounding variables, a high inattention trajectory (compared with low inattention) strongly predicted not having a high school diploma at 22-23 years of age (odds ratio=7.66, 95% confidence interval [CI]=5.06-11.58). To a lesser extent, a declining or rising trajectory of inattention also made a significant contribution (odds ratios of 2.67 [95% CI=1.90-3.75] and 3.87 [95% CI=2.75-5.45], respectively). Hyperactivity was not a significant predictor once inattention was taken into account. CONCLUSIONS: Inattention rather than hyperactivity during elementary school significantly predicts long-term educational attainment. Children with attention problems, regardless of hyperactivity, need preventive intervention early in their development.

An experimental preventive intervention nested into a longitudinal study was used to test the developmental distinctiveness of proactive and reactive aggression. The randomized multimodal preventive intervention targeted a subsample of boys rated disruptive by their teachers. These boys were initially part of a sample of 895 boys, followed from kindergarten to 17 years of age. Semiparametric analyses of developmental trajectories for self-reported proactive and reactive aggression (between 13 and 17 years of age) indicated three trajectories for each type of aggression that varied in size and shape (Low, Moderate, and High Peaking). Intent-to-treat comparisons between the boys in the prevention group and the control group confirmed that the preventive intervention between 7 and 9 years of age, which included parenting skills and social skills training, could impact the development of reactive more than proactive aggression. The intervention effect identified in reactive aggression was related to a reduction in self-reported coercive parenting. The importance of these results for the distinction between subtypes of aggressive behaviors and the value of longitudinal-experimental studies from early childhood onward is discussed.

The authors examined cross-lagged links among gambling, substance use, theft, and violence from midadolescence to young adulthood and whether behavioral disinhibition, deviant peers, and parental supervision as common risk factors explain or moderate those links. In 2 community samples, male Caucasians were assessed for gambling participation and problems with the South Oaks Gambling Screen-Revised for Adolescents (K. C. Winters, R. Stinchfield, & J. Fulkerson, 1993) at age 16 years and the South Oaks Gambling Screen (H. R. Lesieur & S. B. Blume, 1987) at age 23. Other problem behaviors were also assessed both times. Risk factors were measured at age 16. Adolescent substance use was related to subsequent theft and violence but not gambling. Gambling problems were linked to subsequent gambling participation. For adolescents with deviant peers, gambling problems were linked to subsequent theft; this was not the case for adolescents without deviant peers. Only for individuals high on disinhibition did stability of gambling problems resemble moderate stabilities of other problem behaviors. Each risk factor was related to each problem behavior (exception: parenting unrelated to gambling). These risk factors partly explained the cross-lagged links among behaviors and thus may be useful targets of prevention. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

BACKGROUND: Knowledge on the onset and the development of antisocial behavior in females is limited, because most of the research in this domain is based on males. METHODS: We critically reviewed 46 empirical studies that examined developmental trajectories of antisocial behavior in females, notably to help determine whether or not an early-onset/life-course-persistent trajectory exists in females. RESULTS: The review suggested that antisocial behavior in females can follow different developmental trajectories (e.g., early-onset/life-course-persistent, childhood-limited, adolescence-limited, adolescence-delayed-onset, adulthood-onset). However, many of the studies reviewed were limited by factors such as the use of global measures of antisocial behavior, the identification of the trajectories based on threshold criteria, and the small sample sizes. CONCLUSIONS: Future studies should take into account the shortcomings highlighted in this review. Such studies are needed to improve the understanding and prevention of the development of antisocial behavior in females.
