Given the high co-occurrence of social anxiety in autism, no reviews to date have explored how cognitive and behavioural mechanisms identified to maintain social anxiety in non-autistic individuals may operate in autistic individuals. This systematic review evaluated: (1) empirical evidence underlying the Clark and Wells (1995) Cognitive Model of S...

Aims Optimal management of Behavioural and Psychological symptoms of Dementia (BPSD) remains challenging. This report describes using nabilone, a synthetic cannabinoid, in a 61-year-old woman with Alzheimer's dementia (AD) experiencing progressive BPSDs. Methods AM was diagnosed with AD in February 2019 and prescribed donepezil and mirtazapine. In...

Autistic people have a greater need to access services (e.g., health and social care, welfare, justice, etc.), yet face significant disadvantages when doing so, often due to poor two-way communication between service providers and service users. This study aimed to co-develop practical, evidence-based adaptations to facilitate communication between...

Social camouflaging in autism involves hiding social differences and autistic traits to fit in with neurotypical settings and is associated with poorer mental health in both autistic adolescents and adults. This study explored the association between self-reported social camouflaging behaviours and adolescents’ self-report of generalised anxiety di...

Although anti-racist adaptations to dialectical behaviour therapy (DBT) are emerging, little qualitative research exists exploring adolescents’ perspectives on therapists’ approach, cultural competency and humility regarding ethnicity, race and culture (ERC) within DBT. This study explored diverse adolescents’ experiences of talking about ERC durin...

Objectives To explore how healthcare practitioners (HCPs) made decisions about the implementation of digital health technologies (DHTs) in their clinical practice before and during the COVID-19 pandemic. Design A multimethods study, comprising semistructured interviews conducted prior to the COVID-19 pandemic, supplemented with an online survey th...

Background Social camouflaging (hereafter camouflaging) in autism includes factors such as masking and compensating for one's neurodevelopmental differences, and to assimilate or ‘fit in’ with non‐autistic peers. Efforts to hide one's authentic self and autism traits (masking) resemble impression management (IM) in safety behaviours identified in C...

Compared to neurotypical peers, autistic adolescents show greater cognitive inflexibility (CI) which manifests at the behavioral and cognitive level and potentially increases vulnerability for the development of internalizing (INT) and externalizing (EXT) symptoms. This systematic review and meta‐analysis explored the association between CI and INT...

Lay abstract: Autism is a diagnosis given to individuals by professionals but is also increasingly seen as an identity which an individual can choose for themselves. We wanted to explore how having autism as an identity affects autistic young people. There is evidence that autistic adults have better psychological well-being when they feel more so...

Autism is a neurodevelopmental condition that affects individuals across their lifetime, though the effects of ageing in older adulthood are poorly understood to date. This systematic review assessed six characteristics in older autistic adults (cognitive functioning, co-occurring difficulties, autism symptom severity, social integration, adaptive...

Circumstances surrounding the COVID-19 pandemic have resulted in significant personal and professional adjustments. Students and trainees, including those in autism research, face unique challenges to accomplishing their training and career goals during this unprecedented time. In this commentary, we, as members of the International Society for Aut...

We explored the role of negative performance beliefs and self-focused attention considered central to psychological models of social anxiety but not studied in autism. Firstly, we compared self- and observer ratings of performance on a social task for 71 young autistic people, 41 high and 30 low in social anxiety, finding a significant main effect...

Autism is a neurodevelopmental condition that affects individuals across their lifetime, though the effects of ageing in older adulthood are poorly understood to date. This systematic review assessed six characteristics in older autistic adults (cognitive functioning, co-occurring difficulties, autism symptom severity, social integration, adaptive...

Understanding shared and unique constructs underlying social communication difficulties in autism spectrum disorder (ASD) and social anxiety disorder (SAD) can address potential diagnostic overshadowing when evaluating SAD in the context of autism. Using self-report measures, factor analyses examined constructs underlying autistic traits, social an...

Lay abstract: Within the neurodiversity movement, one recent divergence is in the semantic choice of language when describing autism, as members of the autism and autistic community preferred to use identity-first language (autistic person), whereas professionals were more likely to use person-first language (person with autism). This study explor...

Lay abstract: Prior research suggests that autistic students in higher education might struggle with developing autonomy, competence and establish relatedness due to their executive functioning and social communication difficulties. We interviewed 18 autistic and 18 typically developing students to explore how students perceived themselves to be i...

This is the first longitudinal study to quantitatively evaluate changes in social network structure (SNS) and perceived social support (PSS) amongst first-year students on the autism spectrum (n = 21) and typically developing (TD; n = 182) students transitioning to university. The relative impact of changes in SNS/PSS, students’ social anxiety and...

Applying to university can be an anxiety-provoking time for many autistic students, though enrolment can be increased by actively involving them in transition planning. We provide an evaluation of a transition to university pilot programme (Autism Summer School) for autistic students (16–19 years) who are seeking to apply/attend university. The con...

Transitioning to university can be anxiety-provoking for all students. The relationship between social anxiety, autistic traits and students’ social network structure, and perceived support is poorly understood. This study used a group-matched design where autistic students ( n = 28) and typically developing students ( n = 28) were matched on sex,...

The academic, daily-living, and social challenges all students face during university transition can become magnified for many autistic students, who might struggle to adapt to changes in their social network structure (SNS) and perceived social support (PSS). This study assessed the development, feasibility, and convergent validity of a novel onli...

Previous studies using diffusion tensor imaging (DTI) to investigate white matter (WM) structural connectivity have suggested widespread, although inconsistent WM alterations in autism spectrum disorder (ASD), such as greater reductions in fractional anisotropy (FA). However, findings may lack generalizability because: (a) most have focused solely...

Background: Social communication impairments associated with Autism Spectrum Disorder (ASD) is a multi-faceted phenomenon that encapsulates a broad range of skills with Theory of Mind (ToM) as a key component. Early Theory of Mind (ToM) skills, such as joint attention, typically develop during infancy and provide a foundation for the co-emergence o...

Up to 40% of children with Autism Spectrum Disorder (ASD) exhibit co-occurring anxiety symptoms. Despite recent success in mitigating anxiety symptoms in school-aged children with ASD (mean age >9 years) using adapted versions of Cognitive Behavioural Therapy, little is known about potential treatment outcomes for younger children. To address the g...

Parenting children with ASD has a complex history. Given parents' increasingly pivotal role in children's treatment, it is critical to consider parental style and behaviours. This study (1) compares parenting style of parents of children with ASD, parents of children with anxiety disorders, and parents of typically developing (TD) children and (2)...

Pivotal response treatment (PRT) is an evidence-based behavioral intervention based on applied behavior analysis principles aimed to improve social communication skills in individuals with autism spectrum disorder (ASD). PRT adopts a more naturalistic approach and focuses on using a number of strategies to help increase children’s motivation during...

Background Disruptive behavior in Autism Spectrum Disorder (ASD) is an important clinical problem, but its neural basis remains poorly understood. The current research aims to better understand the neural underpinnings of disruptive behavior in ASD, while addressing whether the neural basis is shared with or separable from that of core ASD symptoms...

Up to 1/3 of children and adolescents with ASD demonstrate symptoms of disruptive behaviour and anxiety, affecting daily activities. Both disruptive behaviour and anxiety have been linked to poor self-regulation, though little is known about their relationships wtih each other. This paper examined the use of Default Mode Network as a novel neural w...

Reports of the cognitive enhancing effects of modafinil have been inconsistent across human and rodent literatures. Cognitive enhancements are typically observed on specific tasks above a certain difficulty threshold, being more pronounced in subjects with impaired baseline performance. The current study employs a novel touchscreen task in rodents...

Poster presentation at 2014 Neuroscience Meeting Planner. Undergraduate thesis research project on investigating the role of modafinil’s cognitive enhancing effect in rodents, using a novel self-ordered sequencing touchscreen task.
