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,…

Difficulties regulating emotions have been coined as inherent to autism, possibly even presenting a core difficulty of autism. While several models of emotion regulation have been proposed in the past, in this targeted review article, we aim to map emotion regulation difficulties in autistic individuals within the framework of the extended process…

Relatively little is known about the experiences of parents of autistic teenagers, with the existing research on this life stage principally about transition. This study sought to address this gap. It focused specifically on parents of autistic teenagers with mental health difficulties and/or behaviours that challenge (MHD/BC). The study design…

Pre-registration refers to the practice of researchers preparing a time-stamped document describing the plans for a study. This open research tool is used to improve transparency, so that readers can evaluate the extent to which the researcher adhered to their original plans and tested their theory appropriately. In the current study, we conducted…

Alexithymia and autism are variably characterized by social cognitive and perceptual deficits, which can lead to profound social interaction difficulties. Such difficulties are also the hallmark of personality disorders (PDs), but the potential link between alexithymia, autism, and PDs remains unclear. Here, we investigated whether autistic and/or…

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…

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…

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…

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…

Alongside the rise in online qualitative research, fraudulent representation of research participants is increasing, and current strategies to address this issue within studies of non-neurodiverse samples may exclude autistic voices. Seeking to reduce fraudulent or "scammer" participation in our focus group study, and increase data…

Studies have shown that there are differences between the presentations of males and females diagnosed with autism. There remains a developing understanding about how the presentation of autism differs between boys (hereafter referred to as 'assigned males at birth') and girls (assigned females at birth). This study sought to investigate the…

There is limited literature on the association between parenting practices, parenting stress and externalising behaviours in autistic children. We investigated whether parenting practices mediate the association between parenting stress and externalising behaviours. Parents of school-aged autistic children (n = 138) completed an online survey on…

The quality of life of autistic children and their parents is impacted by the stress they experience, their coping strategies and the availability of professional health, social and educational support services. Recent changes in the structural organisation of child disability professional supports in Ireland mean that in-depth knowledge about…

Studies commonly measure the challenges of caring for autistic adolescents and young adults, but scarcely explore the positive aspects of the caregiving experience. This study employed an equal-status concurrent mixed methods approach to quantitatively assess predictors of positive aspects of caregiving and qualitatively examine 174 caregivers'…
