Autism spectrum disorder has often been assumed to be a protective factor against substance use, yet the extent of substance use in this population has been difficult to determine as limited research has been done on these interacting variables. This systematic literature review examined 26 studies published between 2009 and 2019 to uncover the…

Background: Attention-deficit/hyperactivity disorder (ADHD) is a known risk factor for substance-related problems (SRP) during adolescence, but the nature of this relationship and the importance of co-occurring conduct problems are not fully understood. Methods: Data stem from a linked dataset between a large population-based survey conducted in…

Children with Autism Spectrum Disorder (ASD) often display atypical sensory reactivity within the first years of life, prior to a diagnosis. This study examined sensory reactivity patterns at 14 months, changes from 14 to 23 months, and later ASD severity at 3 to 5 years of age in children (n = 87) at elevated likelihood of ASD. Results indicated…

This study examined sex differences in externalizing and internalizing symptoms of children with ASD without intellectual disability (ID). The sample (n = 80) included 40 girls and 40 boys, ages 6-12 years, with ASD (without ID) matched on age and IQ. Externalizing and internalizing symptoms were significantly elevated for this sample (girls and…

The aim of this study is to investigate the association between prematurity and diagnosis of neurodevelopmental disorders (ND) (attention deficit/hyperactivity disorder [ADHD] or autism spectrum disorder [ASD]) in Brazilian children and adolescents. Case-control study based on medical records data from a specialized outpatient clinic. Prematurity…

Purpose: Adults who stutter (AWS) often attempt, with varying degrees of success, to suppress their stuttered speech. The ability to effectively suppress motoric behavior after initiation relies on executive functions such as nonselective inhibition. Although previous studies found that AWS were slower to inhibit manual, button-press response than…

Background: Attention-deficit/hyperactivity disorder (ADHD) is associated with negative social and occupational outcomes across the life course. However, there has been limited population-based research that quantifies the impact of ADHD on academic achievement and academic trajectories. Aims: To compare academic performance and academic…

Background and aims: Social interactions in preschool and a child's gender are, in cross-sectional studies, related to the child's overall levels of hyperactive behaviour and engagement in preschool activities. However, whether social interaction and gender can predict children's engagement and hyperactivity is not thoroughly investigated. This…

The neurodiversity paradigm is a social justice concept that reframes neurologically based conditions including autism, ADHD, and learning disabilities, as beneficial forms of diversity. A question arising from this framework is the degree to which people forge neurodiversity identities based in self-acceptance. Little is known about identity…

The number of students with disabilities and specifically students with attention-deficit hyperactivity disorder (ADHD) entering postsecondary STEM education has been increasing in recent decades. However, many instructors and popular research-based curricula are not prepared to support such learner variation. The views and experiences of people…

This study analyzes the self-perceptions of social competence in children with attention-deficit/hyperactivity disorder (ADHD). It compares two groups of participants, children with ADHD (N = 20) and children without ADHD (N = 20) ages between 8 and 12 years old. Sociometric questionnaires were completed by two groups of participants and 707…

Parents of children with autism spectrum disorder (ASD) face higher levels of caregiver strain compared to parents of children with other disabilities. This study examined child clinical features that predict high levels of caregiver strain for 374 parents of children with ASD. Caregiver strain was measured using the Caregiver Strain Questionnaire…

Physical activity (PA) benefits children's cognition, in particular executive functions (EF). Children with Attention Deficit Hyperactivity Disorder (ADHD), Reading Difficulties (RD) and co-occurring ADHD/RD have low levels of PA and difficulties with EF. This study evaluated a PA programme to determine recruitment, attrition, feasibility (e.g.…

Although inclusive education policies conflict with punitive discipline measures, inclusion in mainstream schools may coexist with or allow such exclusionary punitive discipline. In Latin America, however, there is scarce research on how punitive measures are distributed, and if and how they affect students with disabilities enrolled in regular…

This study addressed the higher reported failure rates and motivation of college students with ADHD. The problem addressed in this study was that ADHD students withdrew from or failed courses more frequently than non-ADHD students. The purpose of this descriptive qualitative design study was to examine why college students with ADHD were more…
