The purpose of the study was to assess early literacy skills and examine the presence and stability of challenging behaviors across the critical threshold of the kindergarten school year. Students' (n = 337) literacy performance (letter sound fluency, word attack, and phonological awareness) and challenging behaviors (teacher ratings of…

Background: Past research with children with specific language impairment (SLI) has shown them to have poorer planning and problem-solving ability, and delayed self-regulatory speech (SRS) relative to their typically developing (TD) peers. However, the studies are few in number and are restricted in terms of the number and age range of…

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…

This paper integrates the findings from the four studies in this special issue and discusses the implications for school psychology practice. Our research indicates that adolescents with attention-deficit hyperactivity disorder (ADHD) are typically aware of their difficulties and believe that their problem behaviors are pervasive, uncontrollable,…

Sleep disturbances are likely to be associated with emotional and behavioural problems in typically and atypically developing children. The study was aimed to evaluate sleep disturbances in children with autism spectrum disorder (ASD) and their associations with emotional/behavioural problems. The study comprised eighteen 5-year-old boys with…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

The purpose of the study was to establish the vitamin-mineral status of children with autism spectrum disorders (ASD) who exhibit attention-deficit/hyperactivity disorder (ADHD). Four research questions were formulated for the study. A quasi-experimental of ex post facto research design was used. The study was conducted in four special schools and…

To date, the phenotypic significance of EEG abnormalities in patients with ASD is unclear. In a population affected by ASD we aimed to evaluate: the phenotypic characteristics; the prevalence of EEG abnormalities; the potential correlations between EEG abnormalities and behavioral and cognitive variables. Sixty-nine patients with ASD underwent…

This study investigates parents' lived experiences of having a child diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). The aim was to explore parents' meaning-making processes in relation to their children's ADHD with a focus on understanding the impact that receiving a diagnosis had on the parents' perceptions of, and ways of…

A trial-based functional analysis (TBFA) offers several advantages beneficial for classroom settings. TBFA can be completed rapidly, requires fewer resources than traditional functional analyses (FAs), can occur in the natural environment during typically scheduled activities, and involves less intense data collection methods. However, a number of…

In the context of best practices consultation with high needs teachers, we examined (1) relations between teachers' appropriate response to student rule violations and rates of rule violations, and (2) rates of student misbehavior among teachers who do and do not achieve various benchmarks of integrity and/or growth in skills. Participants were 48…

A retrospective chart study of patients on open-label aripiprazole treatment was conducted in the Netherlands to add to the knowledge of aripiprazole in children and young adults with mild and borderline intellectual disabilities (IDs). Fifty-three youths, mean age 14.7 ± 3.4 years and mean IQ 64.5 ±13.8, were included. Treatment responders were…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

Growing evidence demonstrates associations between child race, teacher-child race match, and teacher ratings of externalizing behaviour problems in the early years of school. The present study deepens understanding of the relations between child, teacher, and classroom racial factors and teacher-reported externalizing behaviours by examining…

Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…
