Exploratory structural equation modeling (SEM) was applied to a multiple indicator (26 individual symptom ratings) by multitrait (ADHD-IN, ADHD-HI and ODD factors) by multiple source (mothers, fathers and teachers) model to test the invariance, convergent and discriminant validity of the Child and Adolescent Disruptive Behavior Inventory with 872…

The goal of this study was to investigate the relationship between children with attention-deficit/hyperactivity disorder (ADHD) symptoms and their teachers, and to examine whether this relationship was associated with children's academic motivation. The sample comprised 35 children with clinically elevated levels of ADHD symptoms and 36 children…

Research on school bullying often focuses on the directional path of bullying and/or victimization leading to psychosocial problems, while such one-dimensional views have been shown to be too simplistic. Furthermore, recent research has shown that patterns of bullying at school differ for boys and girls, which makes gender a particularly relevant…

Research Findings: The goal of this study was to examine empirical research on the design, delivery, and measurement of the effects of professional development (PD) for early childhood educators in order to provide insight into what the field has accomplished as well as suggest directions for future PD programs and research. Through the use of…

The impact of a school-based violence prevention program, Second Step, on peer victimization and aggression, and emotion regulation was evaluated among 457 sixth graders. A cluster-randomized trial was conducted with classrooms randomly assigned to intervention (n = 14) or control (n = 14) conditions. A repeated measures analysis of covariance on…

It is still under debate whether the reported effects of opioid maintenance therapy (OMT) on child behaviour are a direct effect of prenatal exposure, or whether other factors are involved. This prospective cohort study investigated three models: the teratogenic risk model, the maternal risk model, and a combined risk model in a group of 35…

Background: Individuals with fragile-X syndrome exhibit developmental delay, hyperexcitation and social anxiety; they also show lack of attention and hyperactivity. Few studies have investigated whether levels of functioning change with increasing age. Here, we explored developmental changes across adolescence in the cognitive and behavioural…

This study investigated female and male early childhood educators' (ECEs) perceptions of young children's aggression and rough-and-tumble play in the Canadian early childhood classroom. Participants were drawn from a larger sample of ECEs who completed an online questionnaire regarding their perceptions of young children's behaviours in the…

A growing body of research has shown that high quality early care and education (ECE) is positively related to the development of children's social and academic skills (e.g., Barnett, 2011; Lamb & Ahnert, 2006; NICHD ECCRN, 2006). There is evidence that high quality ECE experiences can improve children's levels of social adjustment (Bierman et…

The sex-positive framework of sexual development hypothesizes that healthy sexual experiences can be developmentally appropriate and rewarding for adolescents despite the risks involved. Research has not examined whether risky behaviors and rewarding cognitions actually change with sexual debut at a normative or late age. This study measured the…

Research Findings: Strong relationships among children, families, and early care and education (ECE) providers are key to quality infant-toddler care. These relationships are shaped during the initial transition period to group care. We used a mixed methods approach to (a) assess maternal perspectives on the transition to group care, (b) explore…

Early childhood educators' (ECE) perceptions of gender roles may contribute to the development of children's own gender-role identities. This qualitative study examined 40 Canadian female ECEs' perceptions of gender and children's shy, aggressive, and prosocial behaviors. Content analysis of extensive interviews revealed three themes: (1) shyness…

An exploratory, observation-based study sought to strengthen understanding of the development of social communication skills that facilitate academic success, particularly within general education settings. Sixteen middle and high school students with Autism Spectrum Disorders (ASD), all of whom participated in at least one period per day of core…

This study focuses on the associations between family variables and academic and social school readiness in low-income Black children. Analyses drew from the National Institute for Child Development (NICHD) Study of Early Child Care and Youth Development dataset. The participants included 122 children and their mothers. Data collection occurred…

The First Step to Success early intervention program (Walker, 1998) is a secondary prevention intervention that targets primary grade children with moderate or emerging behavior disorders. While the effectiveness of the First Step to Success early intervention program has been documented repeatedly (see Loman, Rodriguez, & Horner, 2010; Walker…
