This study examines how maternal adverse parenting (hostility, neglect, low warmth) and psychological distress explain the associations between child temperament factors and externalizing problems. It also examines if these associations differ according to the child's biological sex. The sample consists of 339 school-age children receiving in-schoo...
Conference Paper
Previous research showed that children who experience maltreatment are at-risk of developing externalizing and internalizing behavior problems (Cicchetti & Toth, 2016; Debowska et al., 2017; Romano et al., 2018). Although these associations are well established, their underlying mechanisms, including mediating effects, are less well understood. Ind...
Article
Relatively few studies have focused on relational factors within the school environment that could moderate the associations between temperament and behavior problems. The purpose of this longitudinal study was to examine whether student-teacher relationship quality (i.e., Closeness, Conflict, and Dependency) moderated longitudinal associations bet...

Introduction Childhood conduct problems (CP) are characterized by maladaptive externalizing behaviors and are linked with poor sleep. CP are highly comorbid with other psychological problems, including attention deficit/hyperactivity disorder and depression, which are also associated with disturbed sleep. The present study examined if childhood CP...
Article
School dropout can be an ongoing process of academic failure and disengagement starting as early as elementary school. Given the importance of early identification of risk factors, the present study examines (a) whether early conduct problems and depressive symptoms predict a higher risk of school dropout, (b) whether depressive symptoms moderate t...

Full-text available
While research addresses neighborhood disorder as leading to conduct problems, the role of individual-level differences in shaping adolescent perceptions of neighborhood has been overlooked. Data on youth, over-selected for childhood conduct problems (N = 744, 58% childhood conduct problems, 47% girls), were used to examine the link between conduct...
Article
Introduction Children with conduct problems (CP) exhibit problematic externalizing behaviors that violate the rights of others and/or societal norms, are likely to present with comorbid psychological problems, engage in high-risk behaviours during adolescence and in turn, display poorer prospective health in adulthood. However, little known about t...
Article
COVID-19 underscores the importance of understanding variation in adherence to rules concerning health behaviors. Children with conduct problems have difficulty with rule adherence, and linking early conduct problems with later adherence to COVID-19 guidelines can provide new insight into public health. The current study employed a sample (N = 744)...
Article
Original definitions of psychopathy suggest the existence of two variants that present with distinct clinical features among antisocial adults, but whether these clinical differences originate early in life or emerge at some point during childhood remains uncertain. We examined if primary and secondary variants follow distinct developmental traject...

Adolescents who have been maltreated are at greater risk of developing both internalizing and externalizing behavior problems (e.g., Gardnet et al., 2019; VanZomeren-Dohm et al., 2016). However, not all maltreated adolescents show high levels of problems (Yoon, 2018), suggesting that some variables might moderate these relations. The aim of this st...

Temperament research has often focused on familial factors that may moderate the associations between temperament and children behaviors (Roubinov et al., 2017). However, as children enter school, their relationships extend beyond those developed within the family environment (Quin, 2017). The primary goal of this study was to examine whether the q...

Despite the high prevalence and the negative consequences of conduct problems (CP) and depressive symptoms (DS) comorbidity, factors that could explain this comorbidity in children, such as temperament, are still poorly understood (Beauchaine & Chicchetti, 2016; McDougough-Caplan et al., 2018). Moreover, while previous findings support the relevanc...
Article
Though conceptually distinct from other behavior problems, indirect aggression (IA) is correlated with physical aggression and is linked to oppositional defiant disorder and conduct disorder from childhood to adolescence. Thus, IA could be part of the clinical picture of children with identified conduct problems (CP). However, trajectories of IA ha...

The three dimensions of psychopathic traits in childhood predict high levels of conduct problems. Theoretical conceptions suggest that, in addition to predicting the onset of conduct problems, traits also contribute to their developmental pathways. However, little is known about the associations between the trajectories of the three dimensions of p...
Article
The Dual Failure Model suggests that peer victimization (social failure) and academic difficulties (academic failure) mediate the association between externalizing and later internalizing problems. The present study sought to better understand why children with externalizing problems develop later internalizing problems by testing the Dual Failure...

Full-text available
The clinical relevance of using a multi-informant approach to assess behavioral problems in youths is well established. However, empirical studies have consistently shown weak agreement across informants (parents, teachers, youths). Moreover, there is no consensus regarding the most valid strategy for combining informant reports to assess these pro...

Objective Clinicians may specify the diagnosis of conduct disorder (CD) as “with limited prosocial emotions” (LPE). This specifier is thought to identify youths with particularly severe and stable symptomatology. However, few studies have examined the clinical usefulness of the LPE specifier among children with childhood-onset CD. The current study...

Full-text available
Studies suggest that girls with externalizing problems (ExtP) who receive school-based mental health services may have more severe impairments than boys. In addition, girls with ExtP who receive mental health treatments have been found do so for shorter durations, but this remains to be confirmed among children receiving school-based mental health...

Les problèmes de comportement et les problèmes dépressifs surviennent fréquemment en cooccurrence à l’adolescence et entraînent leur lot de conséquences. En se basant sur le modèle de Patterson et Capaldi (1990), la présente étude a pour but de valider le rôle des variables de rejet social (rejet par les pairs, insertion sociale) et des difficultés...
Article
Early onset conduct problems (CP) are at high risk of persistence throughout childhood. In addition, previous research has suggested that CP are at higher risk of persistence when they co-occur with psychopathic traits. Among the three dimensions of psychopathic traits in children (callous-unemotional, narcissism, and impulsivity), research has mai...
