Children with autism or attention-deficit/hyperactivity disorder (ADHD) are more likely than neurotypical children to experience eating difficulties, such as picky/selective eating, slow eating, and over/under-eating. Recent studies show that eating difficulties can persist into adulthood for autistic individuals. Yet little is known about the…

Understanding the overlap of symptoms between oppositional defiant disorder (ODD) and obsessivecompulsive disorder (OCD) experienced by youth is pertinent for accurate diagnosis. A quantitative, retrospective, cross-sectional design format was used to assess the relationship between ODD and OCD in addition to evaluating the difference in ODD…

Fragile X syndrome (FXS), the leading heritable cause of intellectual disability, has a co-occurrence rate of autism spectrum disorder (ASD) estimated at ~60%. The onset and rates of motor development in FXS are slower relative to neurotypical development, and even more so in the context of co-occurring FXS + ASD. Extant evidence suggests these…

Despite very high rates of suicidal thoughts and behaviors (STB) in autistic adults, the key psychosocial drivers of this phenomenon remain unknown. To investigate, we examined how lifetime stressor exposure and severity, which have been found to predict STB in non-autistic populations, related to STB in a multinational dataset of 226 autistic…

This study explored predictors of community-based providers' adherence to MATCH, a modular cognitive behavioral therapy for children and adolescents. Provider-reported adherence to MATCH was measured using three increasingly strict criteria: (1) "session content" (whether the session covered MATCH content consistent with the client's…

In the present study, we sought to examine whether face recognition problems impact the social anxiety experienced by autistic people. Many autistic people -- perhaps between 15% and 30% -- exhibit severe face recognition problems that closely resemble developmental prosopagnosia. At present, however, little is known about the psychosocial…

However, there is a dearth…

Introduction: Prescription stimulants are an effective FDA approved treatment for attention deficit hyperactivity disorder (ADHD) however their safety has come under scrutiny. Multiple studies demonstrate safe use in pediatric populations, but prescriptions are increasing to adults and it is not evident which comorbidities might place people at…

Objective: ADHD symptoms are highly prevalent among university students. These symptoms, particularly the inattentive cluster, predispose students to poorer academic performance and worse academic adjustment. Moreover, ADHD symptoms are often comorbid with other common mental disorders; this comorbidity also leads to poor outcomes. South African…

Introduction: Social knowledge is an important aspect of social cognition that pertains to broader knowledge of social concepts and norms. People with intellectual disabilities are more likely to experience mental health challenges, and it's important to pay special attention to how comorbid conditions can affect their social cognition skills,…

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…
