Direct linkHuang, Yunhe; Arnold, Samuel R. C.; Foley, Kitty-Rose; Trollor, Julian N. – Journal of Autism and Developmental Disorders, 2022
Pathways to diagnosis in adulthood are poorly understood. Even less is known about undiagnosed adults who believe they may be autistic. This mixed-methods online survey examined adults' journeys from initial concern to receiving the diagnosis. Quantitative findings showed the diagnostic process to be highly heterogeneous. Qualitative analysis…

Song, Wei; Shea, Lindsay; Nonnemacher, Stacy L.; Brusilovskiy, Eugene; Townley, Greg; Salzer, Mark S. – Journal of Autism and Developmental Disorders, 2022
Little research has examined the full-range of participation among adults on the autism spectrum. The current study addresses this knowledge gap by comparing the frequency, importance, breadth, and sufficiency of participation between autistic adults and adults in the general population. Autistic adults participated less, had fewer areas that were…

Cameron, Lauren A.; Borland, Ross L.; Tonge, Bruce J.; Gray, Kylie M. – Journal of Applied Research in Intellectual Disabilities, 2022
Background: This systematic review aimed to explore how adults with autism participate in the community, the impact of community participation on quality of life and mental health, and factors that support and hinder participation. Method: A systematic review was conducted including studies published from inception to 17 January 2021. Results:…

Evans, Kiah; van der Meer, Larah; Eggleston, Matthew J. F.; Taylor, Lauren J.; Thabrew, Hiran; Waddington, Hannah; Whitehouse, Andrew J. O. – Journal of Autism and Developmental Disorders, 2022
The diagnostic experiences of autistic adults in New Zealand have not been investigated and little is known globally about autistic adults' satisfaction with the autism diagnostic process. This study describes the diagnostic experiences of 70 autistic adults living in New Zealand and explores how these experiences are related to satisfaction…

Thomas, Louisa; Lockwood, Patricia L.; Garvert, Mona M.; Balsters, Joshua H. – Journal of Autism and Developmental Disorders, 2022
Neuroeconomics paradigms have demonstrated that learning about another's beliefs can make you more like them (i.e., contagion). Due to social deficits in autism, it is possible that autistic individuals will be immune to contagion. We fit Bayesian computational models to a temporal discounting task, where participants made decisions for themselves…

Edelson, Stephen M.; Nicholas, David B.; Stoddart, Kevin P.; Bauman, Margaret B.; Mawlam, Laurie; Lawson, Wenn B.; Jose, Caroline; Morris, Rae; Wright, Scott D. – Journal of Autism and Developmental Disorders, 2021
Over the past decade, there has been a growing interest in adults on the autistic spectrum, and more recently, the challenges related to aging in this population. A two-day Think Tank meeting, focused on aging in autism, was convened amongst international leaders in the field of autism research and practice. This meeting included a series of…

Thorsen, Morten; Bilenberg, Niels; Thorsen, Lena; Michel, Tanja Maria – Journal of Autism and Developmental Disorders, 2022
Oxidative stress has been proposed as being important in the pathophysiology of autism spectrum disorders (ASD), and heightened levels of oxidative stress has found in children with ASD. Our aim was to investigate, whether this change is temporary or persist into adulthood. We included 89 adult patients with ASD and sex and age matched controls.…

Lim, Alliyza; Young, Robyn L.; Brewer, Neil – Journal of Autism and Developmental Disorders, 2022
We hypothesized that autistic adults may be erroneously judged as deceptive or lacking credibility due to demonstrating unexpected and atypical behaviors. Thirty autistic and 29 neurotypical individuals participated in video-recorded interviews, and we measured their demonstration of gaze aversion, repetitive body movements, literal interpretation…

MacLennan, K.; O'Brien, S.; Tavassoli, T. – Journal of Autism and Developmental Disorders, 2022
Autistic adults commonly experience sensory reactivity differences. Sensory hyperreactivity is frequently researched, whilst hyporeactivity and seeking, and experiences across domains, e.g., vision, are often neglected. Therefore, we aimed to understand more about the sensory experiences of autistic adults. We conducted a mixed-methods study,…

The Autism Spectrum Disorders in the European Union (ASDEU) survey investigated local services' use experiences of autistic adults, carers and professionals with interventions for autistic adults. The majority of the 697 participants experienced recommended considerations prior to deciding on intervention and during the intervention plan and…

Pan, Cheng-Chen; Wang, Hui-Ting; Adams, David; Kim, Kyungjin – Education and Training in Autism and Developmental Disabilities, 2022
The purpose of this study was to increase the duration of treadmill walking to reach moderate exercise intensity level for a 26-year-old male diagnosed with moderate autism spectrum disorder (ASD) accompanying an intellectual disability. We used a structured system including token reward system of visual representation of progress. A changing…

Schulz, S. E.; Stevenson, R. A. – Journal of Autism and Developmental Disorders, 2022
Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

Understanding Camouflaging as a Response to Autism-Related Stigma: A Social Identity Theory Approach
Perry, Ella; Mandy, William; Hull, Laura; Cage, Eilidh – Journal of Autism and Developmental Disorders, 2022
Camouflaging refers to strategies used by autistic people to mask or hide social difficulties. The current study draws on Social Identity Theory to examine the relationship between camouflaging and autism-related stigma, testing the hypothesis that camouflaging represents an individualistic strategy in response to stigma. Two hundred and…

Ryan, Christian; Cogan, Stephen; Phillips, Ailish; O'Connor, Lorraine – Journal of Autism and Developmental Disorders, 2021
High rates of alexithymia, a condition characterised by difficulties identifying and describing emotions, are frequently reported in both children and adults with autism spectrum disorder (ASD). However, the dilemma of measuring alexithymia via self-report has rarely been addressed. In this study, we compared objective and subjective measures of…

Coburn, Kelly L.; Williams, Diane L. – Journal of Autism and Developmental Disorders, 2022
Challenges to verbal encoding may affect the ability of autistic individuals to express their ideas. Therefore, visuospatial expression may represent a person's knowledge and skills more accurately than spoken language. To test this hypothesis, we asked seven autistic adults to linguistically retell and visuospatially reenact several animated…
