School disruption (SD) places students at risk of early school departure and other negative psychological outcomes. Based on the data derived from a sample of Ontario children and youth, this study aims to identify risk factors associated with SD among 1,241 school-aged students. A logistic regression model revealed that substance use, family…

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…

More students with attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) are being taught within the regular education classroom than ever before even though children with these disorders often require additional educational supports. Therefore, it is critical that teachers understand the challenges experienced by these…

Despite the many studies that have documented the association between symptoms of ADHD and social difficulties in children and adolescents, few have examined this phenomenon in college students. In addition, the underlying factors contributing to such social difficulties are still poorly understood. We hypothesised that college students with…

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…

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…

Few classroom behavioral interventions have been thoroughly studied using culturally and linguistically diverse populations, international student populations, or those from diverse socio-economic backgrounds. Yet, having such tools for school psychologists and teachers is critical for behavior management in the classroom. One important exception…

We examined inattention/overactivity (I/O) over time and in relation to caregiving in three matched groups: (1) Romanian Orphans (RO) with a minimum of eight months' deprivation prior to adoption, (2) Early Adopted (EA) children adopted from Romania prior to age four months, and (3) Canadian Born (CB) non-adopted children. Comparisons among groups…

The authors examined changes over a 1-year period in mothers' attributions for child behavior and child oppositional behavior among 53 mothers and nonproblem sons and 44 mothers and sons with attention-deficit/hyperactivity disorder (ADHD). Boys averaged 8 years of age (SD = 11 months) at Time 1. Families were primarily of European Canadian…

We begin with the suggestion that the definition of Attention Deficit Hyperactive Disorder (ADHD) still faces some challenges. Conceptually, inhibition of the Pavlovian kind preexisted the "behavioral inhibition" popular in the USA; the difference between them has to be understood in order to understand ADHD. The present project examines…

Fetal Alcohol Spectrum Disorder (FASD) is a term that encompasses the various neurodevelopmental disorders experienced by individuals with prenatal alcohol exposure. FASD incorporates the terms Fetal Alcohol Syndrome (FAS), Fetal Alcohol Effects (FAE), and Alcohol-Related Neurodevelopmental Disorder (ARND). Early studies showed that students with…

Hyperactivity, impulsivity, and inattention are among the most common behaviour problems in children. The aim of this study was to estimate the prevalence of hyperactivity-impulsivity and inattention in the Canadian population of 2-11-year-old girls and boys, using data from the first National Longitudinal Survey of Children and Youth (NLSCY)…
