Elopement is a common and dangerous behavior among autistic children. Behavioral treatments can reduce elopement, but most evidence comes from small-N evaluations in specialized settings with strategies varying across studies. The current study compared the efficacy of the caregiver-mediated function-based elopement treatment to parent education…

Emerging research suggests that episodic memory challenges are commonly encountered by autistic individuals; however, the specific nature of these memory challenges remains elusive. Here, we address critical gaps in the literature by examining pattern separation memory, the ability to store distinct memories of similar stimuli, and its links to…

Autistic people experience high rates of mental health problems. A tendency towards behavioural repetition in autistic individuals could contribute to repetitive negative thinking, which is a transdiagnostic risk factor for mental health problems. Our research aimed to add to the literature by using transdiagnostic measures of both mental health…

Obsessive-compulsive disorder commonly co-occurs with autism. Research characterising the interplay between restricted, repetitive behaviours, activities and interests related to autism and obsessive-compulsive disorder symptoms has used theory-driven, bottom-up methodology. This study aimed to interview autistic adults about the subjective…

Shared family meals are associated with family functioning and thought to protect against disordered eating in families with neurotypical children. Limited research, however, has examined the mealtime structure or experience in families with children with autism (Autism spectrum condition) and/or attention deficit hyperactivity disorder, despite…

Rates of self-injurious thoughts and behaviors are elevated among autistic youth, yet research is limited to caregiver report or single-item questionnaires. Investigation of specific suicidal thoughts, triggers, and disclosure is needed to improve risk assessment and interventions. The current study characterized self-injurious thoughts and…

Autistic meltdowns have been explored from the perspectives of parents, but there is a paucity of research on the experience of meltdowns from the autistic perspective. Little is known about how adults experience these events. In this descriptive phenomenological study, we conducted online interviews with 32 autistic adults on the experience of…

To explore associations between autism traits and family functioning over time, we studied longitudinal data of a mixed group of 168 clinically referred autistic and non-autistic children. Cross-lagged models showed a significant association between fewer autism traits at the diagnostic assessment and better family functioning 1 year later for the…

Echolalia has been described as the repetition of words, phrases, songs or other more elaborate dialogues uttered by another person, which may be immediate or delayed (International Classification of Diseases, 11th Revision; "Diagnostic and Statistical Manual of Mental Disorders", 5th ed.). Some classify echolalia as a communication…

Anxiety has been associated with social communication and interaction differences among autistic children. We sought to clarify the direction of these associations longitudinally, and test executive function as a moderator. Participants were autistic children (N = 157; 15% female, 85% male) engaged in a longitudinal study. Analyses focused on two…

While the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) is considered a "reference standard" measure to observe symptoms of autism spectrum disorder (ASD), little is known about the utility of its Other Abnormal Behaviors or "E codes." This study investigated the unique influence of each E code (overactivity,…

Insistence on Sameness has been pathologized as a subtype of restricted, repetitive patterns of behavior, interests, or activities, in autism. We examined the meanings of Insistence on Sameness for autistic adults through the lens of critical autism studies and environmental psychology, exploring their foodways and experiences of food…

Over the past few years, screen-based usage among children and youth has increased significantly, particularly among those with autism. Yet current screen time guidelines do not address the specific needs of autistic children and youth. Therefore, the objective of this study was to develop specific and clear guidelines and strategies that…

Little is currently known about the autism spectrum disorder (ASD)-related difficulties of females narrowly below the ASD diagnostic threshold and whether the disorder conceptualisation should be broadened to capture their presentations. We extracted fine-grained information from the assessment reports of 222 children who were either diagnosed…

Naturalistic developmental behavioral interventions are an empirically supported intervention approach for young autistic children. Despite the prevalence of disruptive behaviors among autistic children, most manualized caregiver-mediated naturalistic developmental behavioral interventions include limited formal guidance on when and how to manage…
