Past meta-analyses show that both child-mother and child-father attachment insecurity are independently and jointly associated with more externalizing behaviors in children. Little is known, however, on the ways that different types of insecure attachment independently and jointly predict the development of externalizing behaviors over time.…

In recent years, preschooler's self-regulation has been extensively researched. This systematic review deals with the overlaps and differences among the many different terminologies and definitions of self-regulation in childhood and the association with preschooler's social-emotional and behavioural development. A systematic literature search in…

The study explores whether physical activity (PA) in early adolescence limits the risk of internalizing and externalizing problems in youth with difficult temperaments, from low-income families, or exposed to impaired family functioning. Participants (N = 1312; 53% girls) were drawn from the Quebec Longitudinal Study of Child Development (QLSCD).…

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…

Problematic and disruptive behaviours continue to be a pervasive problem in elementary school classrooms across the globe, with recent reports indicating rising trends. The present study seeks to describe a unique sample of children who are seeking mental health services and present with specific problematic school behaviours. Preliminary analyses…

There is growing evidence of the effectiveness of the pyramid model (PM) in promoting young children's social-emotional competence and reducing challenging behaviours. In the province of Quebec (Canada), as in many other regions, many children with special needs are integrated into early childhood settings where educators have not had specific…

To help a group of nine adolescent boys with behavioural needs improve their social-emotional skills, the researcher designed and conducted a longitudinal intervention at a public secondary school in British Columbia. In order to complete this task, the researcher drew on the various strengths of action research, lesson study and learning study.…

Estimates suggest that nearly 475,000 children and youth attending schools in the US are diagnosed with emotional and behaviour disorders (EBDs) such as childhood depression, dysthymia, conduct disorders, oppositional defiant disorder, attention deficit/hyperactivity disorder, selective mutism, and autism. Estimates of prevalence in Canada are…

Background: Mental health is a priority for high schools, but extant programs often focus on symptom reduction rather than promoting adolescents' developmental assets. Objective: The goal of this study is to examine whether Art in Mind (AIM), a strengths-based after-school organized art activity tailored to fit the needs of adolescents with…

Intellectual impairments in preschoolers have been widely studied. A regularity that emerges is that children's intellectual impairments have an important impact on later adjustments in life. However, few studies have looked at the intellectual profiles of young psychiatric outpatients. This study aimed to describe the intelligence profile of…

There is growing concern about the mental health and resilience of today's children and difficulties with self-regulation are implicated in educational outcomes, cognitive problems, internalizing problems such as depression and anxiety, externalizing problems such as aggression, and physical health problems. Self-regulation is a growing topic of…

To understand the perspectives and needs of autistic children and their families in the context of an emergency, 109 parents and 56 autistic children (5.75-18 years) from Canada completed an online survey about needs, barriers and facilitators to coping with the pandemic. Parents' concerns about their child's development and difficulties managing…

Children with Attention Deficit Hyperactivity Disorder (ADHD), a neurobehavioral disorder prevalent in childhood, demonstrate a persistent pattern of inattention and hyperactive and/or impulsive behavior that is more severe than their typically developing peers. Much of this challenging behavior is observed in the classroom. However, current…

This study explored the relationship between electronic media use, sleep and behaviour in preschool-aged children between the ages of three and five years. The primary hypothesis of this study was that excessive electronic media use (>2 hours a day) would positively correlate with sleep patterns (in particular, disturbances) and negative…

This study examined the longitudinal contribution of four different childcare arrangements attended during the preschool years to social behaviors and academic achievement up to age 15 years. Children participating in a Canadian longitudinal survey with available information on childcare attendance between ages 3 and 5 years (N = 6,852) were…
