Chromosome 22q11.2 deletion syndrome (22q11DS) is characterised by a complex behavioural phenotype including anxiety, attention-deficit/hyperactivity disorder and psychosis. In the current study, we aimed at improving our understanding of the heterogeneity of behavioural characteristics in a group of 129 young people (aged 4022) with a confirmed…

To illuminate individual differences in the development of attention-deficit hyperactivity disorder (ADHD) symptoms in the general population, psychometric measures are needed that can capture general population-level symptom variation reliably, validly, and comparably from childhood through to the transition to adulthood. The ADHD subscale of the…

Purpose: Recent studies have shown that many children who stutter may have elevated characteristics of attention-deficit/hyperactivity disorder (ADHD). Although childhood ADHD commonly persists into adulthood, it is unclear how many adults who stutter experience aspects of ADHD (e.g., inattention or hyperactivity/impulsivity). This study sought to…

Objective: To provide additional information about clinical features associated with adult ADHD in patients diagnosed in childhood compared to those first diagnosed in adulthood. Method: We stratified a sample of adults with ADHD into patients diagnosed in childhood versus adulthood and compared demographic and clinical characteristics. Results:…

Purpose: This study examined predictors of sexual victimization among autistic and non-autistic college students. Specifically, we aimed to determine whether autistic students are more likely than non-autistic students to experience unwanted sexual contact and sexual assault, controlling for co-occurring diagnoses. We also aimed to determine…

The current study examined whether children with and without ADHD differed in text processing when contradictory information was present. Forty-seven children between 10 and 14 years old performed a self-paced reading task. Half the passages contained contradictory information. Additionally, language and cognitive skills were assessed to examine…

Children with special educational needs (CSEN) in the early years have been identified as vulnerable to the pandemic restrictions. This study explored the lived experiences of educators teaching CSEN online in Hong Kong during the COVID-19 school closures. Semi-structured interviews with 21 educators revealed that educators perceived the prolonged…

Background: Prior studies examining the sleep of adolescents with and without attention-deficit/hyperactivity disorder (ADHD) have relied on mean values such as average sleep duration, which masks intraindividual variability. The objective was to investigate whether adolescents with ADHD have greater intraindividual variability of sleep/wake…

Attention-Deficit/Hyperactivity Disorder (ADHD) includes a multitude of symptoms and can be difficult to diagnose due to a variety of international definitions. Research identifies different viewpoints on diagnosis and treatment including medical, psychological, and sociocultural views. Some research suggests ADHD is a social construct and is…

Attention-deficit/hyperactivity disorder (ADHD) is characterized by inattentive, hyperactive, and impulsive behaviors. Impairment in individuals diagnosed with ADHD is significant; one such domain of impairment is achieving a college education. College students with ADHD tend to have lower grade point averages, take longer to graduate, and have…

The present study explored (a) whether differences between students with and without ADHD in reading comprehension are explained by their executive functions, and (b) the unique and shared contribution of the various executive functions to reading comprehension ability. To address these questions, ninety-six adolescents with and without ADHD…

The present study attempts to expand our understanding of frustration, clinical symptoms, and working memory by examining the unique contribution of attention-deficit/hyperactivity disorder symptoms and frustration to working memory capacity (WMC). A factor-analytic framework was utilized to isolate and examine WMC based on results from three…

The Positive and Negative Affect Schedule (PANAS) has been widely used to assess affect expression. Shortened and adolescent versions of the measure have been created, such as the 10-item PANAS for Children (PANAS-C). However, affect expression often involves substantial intraindividual variability, and no research has examined within-person…

Individual differences in executive functions (EF) are heritable and predictive of academic attainment (AA). However, little is known about genetic contributions to EFs or their genetic relationship with AA and intelligence. We conducted genome-wide association analyses for processing speed (PS) and the latent EF measures of working memory (WM)…

Background: Positive interactions with peers are critical to the everyday school experiences of students. Students with disabilities can benefit from social interactions during their general physical education (PE) classes, particularly if such interactions are extensive, frequent, meaningful, and positive and if equal-status relationships are…
