Studies of the association between dyslexia and mental health have typically tried to minimise the influence of dyslexia comorbidities on the outcomes. However, in the "real world", many children with dyslexia have these comorbidities. In this study, we tested (1) if children with dyslexia with three common comorbidities -- inattention,…

The purpose of this study was to evaluate the reliability and validity of the Korean Behavior Assessment System for Children 3rd Edition Teacher Rating Scales--Child Form (K·BASC-3 TRS-C). We used the generalized partial credit model based on item response theory (IRT) to examine the internal validity of the scale's items and the latent trait in a…

Poor reading has been linked to negative outcomes on a wide range of emotional-behavioural dimensions in children. However, little is known about the time course of these associations. In this study we analyse data from a sample of Finnish children (N = 199; 106 boys) which included measures of reading fluency in grade 1 (age 7 or 8), and…

Objective: Neurotypical individuals can prioritize particularly valuable information in working memory. This is a well-replicated effect, demonstrated across a wide variety of task factors and age groups. However, it is not clear if individuals with symptoms of ADHD are able to do this effectively, as there is some evidence this group struggle to…

Objective: This study aimed to objectively assess signs of hyperactivity in adults suspected of having ADHD, addressing potential sex bias in diagnosis. Methods: About 13,179 (49% female) adults with an average age of 33 years with ADHD and 1,910 (41% female) adults with an average age of 36 years without ADHD were included. Motor activity was…

Symptoms of inattention (IA), hyperactivity, and impulsivity present in school-aged children are important indications of developmental problems. The assessment of these symptoms largely relies on questionnaires completed by parents, teachers, and the children themselves. However, inherent perceptual biases may lead to inaccuracies in these…

This study investigated the effectiveness of applying a smartphone to reduce the hyperactive/impulsive behaviors of 3 students with attention deficit hyperactivity disorder (ADHD) in class. A smartphone that can simultaneously provide vibration and visual text prompts was adopted in this study to remind the participants when they exhibited…

Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Objective: This study aimed to investigate the relationship between Cognitive Disengagement Syndrome (CDS) symptoms in children/adolescents and their parents within the Turkish population, examining the association with co-occurring ADHD symptoms, peer/social relationships, and total difficulties. Method: The study included 229 parents aged 18 to…

Objectives: There is a need to examine the utility of objective measures of attention-deficit/hyperactivity disorder (ADHD) symptoms in children. Objective measures of ADHD symptoms, such as physical activity, may provide a more nuanced assessment of behavior that can be used to augment traditional cross-informant ratings of ADHD symptoms by…

Introduction: This study seeks to psychometrically evaluate the inattention and hyperactivity/impulsivity subscales of the Vanderbilt ADHD Teacher Rating Scale (VADTRS) for the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents in Chile. Method: The sample included 353 students from the 2nd grade of primary…
