Group social skills interventions (GSSIs) are among the most commonly used treatments for improving social competence in youth with ASD, however, results remain variable. The current study examined predictors of treatment response to an empirically-supported GSSI for youth with ASD delivered in the community (N[subscript total]=75). Participants…

Academic accommodations for students experiencing disabilities are increasingly available at postsecondary institutions. More studies of the efficacy of accommodations for student success are warranted, however. Given the increased gender gap in university participation, more focus on the unique impact of gender is also needed. Using a sample of…

Research on stimulant misuse among students has been rising. These medicines are generally prescribed to treat ADHD, but they are also used by students to enhance their academic performance. To date, qualitative research on the topic is limited, specifically in understanding the "process" of misuse, i.e. the motivations embedded in a…

Attention-deficit/hyperactivity disorder (ADHD) overdiagnosis and overtreatment unnecessarily exposes children to potential harm and contributes to provider and community skepticism toward those with moderate or severe symptoms and significant impairments, resulting in less supportive care. Yet, which sociodemographic groups of children are…

Objective: Children with ADHD exhibit deficits in academic motivation compared to their peers. Yet conceptualizations of motivation according to prominent motivation theories connected to achievement have not been studied in college-bound youth with ADHD symptoms. Method: This study examined motivation according to these theories, differences in…

Objective: The QbTest that combines a continuous performance task (CPT) with a motion-tracking system may help identify attention deficit hyperactivity disorder (ADHD). This study examined the structure and diagnostic ability of the QbTest in children and adolescents. Method: Retrospective data from 1,274 children and adolescents were analyzed.…

Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are highly heritable neurodevelopmental disorders that frequently co-occur. Both rare and common genetic variants are important for ASD and ADHD risk but their combined contribution to clinical heterogeneity is unclear. In a sample of 39 ASD and/or ADHD families we…

Among preschool children referred for psychological assessment and intervention, attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed disorder. In order to create school-based interventions that are consistently and effectively implemented by teachers, it is important to understand teachers' knowledge and beliefs about…

Shared difficulties with cognitive control may play a role in co-occurring mental health problems frequently observed in autistic children. We investigated how different cognitive control processes (inhibitory control, conflict resolution, cognitive flexibility) associated with traits of autism spectrum disorder (ASD),…

Despite their negative effect, preschool suspension and expulsion are prevalent. Researchers have explored adverse childhood experiences and teachers' racial bias that link to disproportionate suspension and expulsion in preschools, but little research has investigated disability status as a risk factor. This study investigates the extent to which…

Background: Given the significant behavioral heterogeneity characterizing children with neurodevelopmental disorders and disabilities (NDD/D), the current study examined whether cluster analysis could classify a diverse sample into more homogeneous subgroups. Aims: We first utilized cluster analysis to identify subgroups of children demonstrating…

Until the advent of the DSM-5, the diagnostic systems excluded diagnosis of Attention-Deficit/Hyperactivity Disorder (AD/HD) and Autism in the same child. However, much debate exists surrounding the validity of this exclusion, with a number of studies identifying individuals who meet the diagnostic criteria for both disorders. The aim of this…

Students with ADHD can benefit from at-home learning in terms of managing their symptoms; however, lockdown restrictions due to the pandemic are having negative impacts on the student population. This study was designed to ascertain how students with ADHD have been impacted by at-home learning under lockdown restrictions. An interpretative…

Although numerous studies have analyzed organizational interventions with children with ADHD, minimal research has evaluated the impact of teaching universal organizational skills, classwide, to elementary aged students. This study investigated the impact of teaching organizational skills classwide to two classrooms of Grade 3, 4, and 5 general…

The current study investigated longitudinal associations between parent-rated temperament, observed exuberance and accelerometer activity level at 18-months and symptoms of ASD and ADHD at 36-months in a sample of 54 children at elevated likelihood for ASD. For the specific parent-rated temperament scales, most observed significant associations…
