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…

Control-measure use for this clientele has now been reduced. How do management personnel, families and care teams explain the changes? What clinical interventions did…

Teacher-student relationships (TSR) have long been demonstrated to have significant impact on student outcomes. There has been far less research, however, focused on identifying the specific mindsets that educators' hold which influence their actions toward students. As relationships are situated and contextual and qualitative in nature, this case…

Mothers experiencing psychological distress in the postpartum period may have difficulties parenting their children. Inconsistent and unresponsive parenting may increase the risk of later emotional and behavioural problems in children. The purpose of this study was to identify how maternal psychological characteristics cluster at eight weeks…

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…

This investigation examines the spread of problem behaviors (substance use and delinquency) between twin siblings. A sample of 628 twins (151 male twin pairs and 163 female twin pairs) drawn from the Quebec Newborn Twin Study completed inventories describing delinquency and substance use at ages 13, 14, and 15. A 3-wave longitudinal actor-partner…

This study used a genetically controlled design to examine the direction and the magnitude of effects in the over-time associations between perceived relationship quality with mothers and adolescent maladjustment (i.e., depressive symptoms and delinquency). A total of 163 monozygotic (MZ) twins pairs (85 female pairs, 78 male pairs) completed…

A number of studies report that from the first years of life, preterm children have more difficulty self-regulating and communicating in their social group. If these children show signs of difficulty adjusting socially, the question then is whether or not these problems continue and persist over time. The objective is to observe the combined…

Children with conduct problems are at greater risk for internalizing problems. The objectives of this study were to (1) examine trajectories of internalizing problems among children with and without clinically significant conduct problems during the transition to adolescence; and (2) identify how academic achievement, peer rejection, parent…

It is believed children stand to benefit from a greater male teacher presence in early childhood education (ECE) where, internationally, the vast majority of ECE teachers are female. This study (N = 180) examines the relationship between children's social adaptation and the educational practices of 53 ECE teachers, 23 (44%) of which were male.…

Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting,…

The purpose of this study was to examine the relationship between inattention, academic enabling behaviors (i.e., motivation, engagement, and interpersonal skills), and early literacy outcomes. Kindergarten students (N = 181; 55.2% male; 62% white) from two research sites (Southeastern U.S. and Eastern Canada) were assessed using the Letter Naming…

Over the last two decades, moves toward "inclusion" have prompted change in the formation of education policies, schooling structures and pedagogical practice. Yet, exclusion through the categorisation and segregation of students with diverse abilities has grown, particularly for students with challenging behaviour. This paper considers…

Although there is much research on School-Wide Positive Behavioural Interventions and Supports (PBIS) in the United States, there is little such research in Canada. The purpose of the current study was to provide a case study example of the relation between implementing PBIS and student academic and behavioural outcomes, as well as student…

While a significant number of individuals in Canada and globally are affected by prenatal fetal alcohol exposure, scant research exists that focuses specifically on the subjective experiences of this population. Based on a single case study exploring through Photovoice methodology the life experiences of a young adult with Fetal Alcohol Spectrum…
