Autism significantly impacts how individuals interact, communicate and perceive the world. Gastrointestinal disturbances, particularly constipation, are prevalent among autistic people, affecting their overall well-being. However, to the best of our knowledge, no specific guidelines are currently available regarding the diagnosis of constipation…

Fixel-based analysis was used to probe age-related changes in white matter micro- and macrostructure of the corpus callosum between participants with (N = 54) and without (N = 50) autism spectrum disorder (ASD). Data were obtained from the Autism Brain Imaging Data Exchange-II (ABIDE-II). Compared to age-matched controls, young adolescents with…

Purpose: Prior work developed a shortened 16-item version of the Social Responsiveness Scale (SRS), a quantitative measure of social communication and autism spectrum disorder (ASD)-related traits. However, its properties for use in risk factor estimation have not been fully tested compared to the full SRS. We compared the associations between…

This study tests a handwriting model for children and youth with Autism Spectrum Disorder (ASD) that displays the relationships between handwriting process and product characteristics, and the predictors of these characteristics. Structural Equation Modelling was used to test the model for children and youth with ASD (n = 50) and typically…

This study aimed to conduct a scoping review to know children and adolescents' main oral health concerns with Autism Spectrum Disorder (ASD) and thus identify any oral characteristic that stands out, aiming at preventive and interceptive clinical conduct. A search was performed in the three electronic databases and the gray literature; in…

Autistic traits are found throughout the general population, but their link to creative attributes has received little attention in childhood populations. In adults, autistic traits are linked to both creative benefits and disadvantages, moderated by the autistic trait and the creative domain under investigation. The current study investigates the…

Behavioral correlates to happiness (i.e., indices of happiness) have been used as means of measuring happiness in individuals with developmental disabilities. However, research has not yet evaluated the possibility that indices of happiness/unhappiness (IHUs) may signal the presence of a setting event that could affect other behaviors. The purpose…

Autobiographical memory (ABM) and social cognition are mutually constituted, and both are affected in autism. Meanwhile, very little is known about the heterogeneity of ABM in autism, how ABM differences are present in real-world contexts, and how to best respond to autistic children's ABM differences. The goals of this qualitative study were to…

According to relational frame theory (RFT), temporal relational responding is key to important repertoires, including sequencing, ordering, planning, and time understanding. Previous studies have taught several other varieties of relational responding (e.g., comparison, deictics) but relatively little work has been done in the case of temporal…

Children with autism frequently present with complex mental health diagnoses and psychotropic medications are often a component of comprehensive biopsychosocial treatment plans for these conditions. The purpose of this study is to provide rates and patterns of psychotropic medication use, and predictors thereof, in children and youth with autism…

Previous studies have reported that people with autism spectrum disorder (ASD) have higher levels of loneliness than neurotypical (NTP) people, most likely because of their difficulties in social communication with their predominantly NTP peers. However, direct investigations on the causal influence of friendship on their feelings of loneliness is…

This study investigated how emotional valence of a perceived emotional state impacted performance on the Reading the Mind in the Eyes task (RMET) in adolescents with autism spectrum disorder (ASD) and typically developing (TD) controls. Valence of items on the RMET, Adult (RMET-A) and Child (RMET-C) versions, was first classified in a survey of…

We conducted a systematic review of the literature to evaluate the quality of the dietary data and the methods used to obtain them in studies with children and adolescents with ASD. The search of PsycINFO, PubMed, SciELO, and Web of Science using SPIDER strategy retrieved 1975 studies. Data on dietary intake assessment methodologies were…

Purpose: Social media sites provide autistic youth a familiar space to interact that is devoid of many of the challenges that accompany face-to-face interactions. As such, it is important to determine whether the linguistic profiles observed during online interactions are consistent with face-to-face interactions. This preliminary study took a…

Purpose: This qualitative study examines autistic adolescents' perception of the quality of their relationship with their parent using the Three Minute Speech Sample. Methods: Twenty autistic youth (13-17 years; 83% male) spoke, uninterrupted, for three minutes about their thoughts and feelings regarding their mothers. Audio-recorded speech…
