Autistic individuals are twice as likely to meet criteria for anxiety than neurotypical children; yet we lack understanding of early presentations of anxiety in young autistic children, especially those with cognitive impairment. This study is the first to utilize an autism-specific anxiety diagnostic interview with 28 preschool cognitively…

Purpose: Increased local-to-global interference has been found in those with ASD, AD and OCD, and as such, may represent a transdiagnostic marker. As a first step to investigating this, we aimed to assess the overlap in traits of these disorders in a non-clinical sample, and whether local-global processing relates to the traits of the three…

Purpose: Adolescents and adults with Down syndrome are noted to display symptoms and behaviors consistent with a diagnosis of Obsessive Compulsive Disorder. While evidenced-based interventions, including psychopharmacology and therapeutic interventions including exposure and response prevention, exist and effectively treat obsessive-compulsive…

The mental health and well-being of children and adolescents are critical public health concerns globally. This cross-sectional study analysed nationally representative data from the combined 2016-2022 National Survey of Children's Health (n = 239,534) to produce estimates of parent-reported diagnoses of children's anxiety, depression and…

Background: Advancements in medicine have increased the life expectancy of the people with profound intellectual and multiple disabilities. The hypothesis is that as parents get older, they worry about no longer being there for their child. This paper explores the extent to which the experiences of older parents may differ from that of younger…

In autistic adults, measurement tools may not adequately differentiate between autistic characteristics and features of anxiety. This may be particularly evident in the case of social anxiety disorder; however, few measures of social anxiety disorder have been validated for autistic adults. Instead, assessments are often made using measures…

Background: Anxiety impairs adolescent development and is a risk factor for psychopathology. However, factors related to anxiety impairment's severity remain poorly studied. Objective: This study aims to document anxiety impairment across different domains in adolescents and to study associated factors (sociodemographic, specific anxiety, and…

Introduction: While social networks have become an integral part of people's lives, they also bring the potential for negative consequences, with problematic social network use emerging as a noteworthy concern, especially among adolescents. Guided by social control theory, this study examined bidirectional relationships between problematic social…

Objective: Previous research demonstrates that sociocultural appearance pressures and internalization of appearance ideals lead to disordered eating (DE); however, only a subset of individuals exposed to these influences develop clinically significant DE. Identifying moderators of these associations may increase efficacy of targeted preventions…

Objective: Children with ADHD often experience functional impairments across various aspects of daily life. This study addresses the dearth of longitudinal research on functional impairment trajectories from preschool to school age in children with symptoms of ADHD and comorbid disorders. Methods: We investigated the extent to which functional…
