Objective: Some studies show an association between ADHD and impaired balance/gait in children. However, it remains largely unexplored whether such an association exists in adults. We explore that association in this study. Method: This cross-sectional study included 45 adults aged 17 to 21 (25 with, and 20 without ADHD), most obtained from a…

The purpose of this study was to determine whether adolescents with and without attention-deficit/hyperactivity disorder (ADHD) differ regarding their friendships. The sample comprised 107 adolescents (59 ADHD, 48 typically developing comparison), ages 13 to 18 years. Adolescents and their parents completed questionnaires that measured the number…

A recent study suggests that parent report on the Social Symptom and Prosocial scales of the Childhood Joint Attention Rating Scale provides useful information about differences in the social development of school-aged autistic children. The current study provides additional psychometric data on the Childhood Joint Attention Rating Scale regarding…

Despite the presence of many studies on the conduct and adjustment traits of typically developing siblings of children with autism spectrum disorder (sibs-ASD) in the literature, studies examining the risk of siblings developing a psychiatric and psychological disorder or neurodevelopmental disability are limited. This study aims to comparatively…

To examine reliability, validity, factor structure, and measurement invariance (i.e., configural, metric, and scalar invariance) of the Japanese Conners' Adult attention deficit hyperactivity disorder (ADHD) Rating Scales (CAARS), Japanese nonclinical adults (N = 786) completed the CAARS Self-Report (CAARS-S). Each participant was also rated by…

Objective: Previous studies have linked ADHD with self-harm, but the processes underlying this association are not fully understood. This research aims to investigate the role of sleep disturbances as a potential pathway between ADHD diagnosis and self-harm behaviors. Materials and Methods: The study included 90 youth aged between 11 and 18 years,…

Background and Purpose: Schoolchildren with language difficulties experience more peer victimization compared to their typically developing (TD) peers. Whether these children also bully their peers (bully perpetration) more than TD children is unclear. Furthermore, little is known about peer victimization and bully perpetration among preschool…

Objective: Maladaptive daydreaming (MD) is characterized by vivid, excessive fantasy activity that becomes prioritized over other activities and may result in avoidant coping strategies. Little is known about the relationship between MD and internalized stigma in the neurodivergent sample. The current study aimed to examine emotional…

Objective: ADHD is subject to stigma from the general population. Exposure to stigma poses the risk of developing self-stigma of youth and parents, but few studies have focused on self-stigma of ADHD. Furthermore, parental factors have been implicated in self-stigma of youth, but no previous research has assessed the association between…

This study investigated attributions and stigmatization self-perceptions of 40 adolescents with and 34 adolescents without ADHD for their problematic behaviors and ADHD as a disorder. Adolescents identified behaviors that they believed described them, indicated which of these behaviors was most problematic for them, and responded to a…

College students with attention-deficit/hyperactivity disorder (ADHD) are at higher than average risk for alcohol and substance use; however, it is unclear whether having ADHD, either alone or in combination with other factors, increases this risk. Further, no prior studies have systematically examined factors that correlate with alcohol and…

Temporal proximity is one of the key factors determining whether events in different modalities are integrated into a unified percept. Sensitivity to audiovisual temporal asynchrony has been studied in adults in great detail. However, how such sensitivity matures during childhood is poorly understood. We examined perception of audiovisual temporal…

Research on aggression in the West has focused mainly on the dichotomy between proactive and reactive aggression, but not the co-occurring proactive-reactive aggression subtype, despite its prevalence. The authors investigated the differences in psychological and behavioral correlates among proactive, reactive, and proactive-reactive student…

Forty-seven college students with ADHD and 44 non-affected control participants completed two self-report questionnaires and six tests…

Background: Attention deficit hyperactivity disorder is increased in children with intellectual disability. Previous research has suggested stimulants are less effective than in typically developing children but no studies have titrated medication for individual optimal dosing or tested the effects for longer than 4 weeks. Method: One hundred and…
