Autism spectrum disorder: An examination of sex differences in neuropsychological and self-report measures of executive and non-executive cognitive function / Eleni A. DEMETRIOU in Autism, 25-8 (November 2021)

One area not studied in detail is whether females and males with autism perform differently in tests of cognitive ability. The results of previous research are quite mixed. One explanation may be that some research comparing females and males with autism did not include a neurotypical control group for comparison. As a result, it is not clear whether the sex differences in cognitive ability observed in people with autism are similar to differences between neurotypical males and females. To better understand whether there are unique differences between males and females with autism, it is important to also compare them with neurotypical males and females. In our research, we included a neurotypical group and compared males and females with and without a diagnosis of autism. We found that the sex differences in autism are similar to what we observe in males and females without autism. Our study showed that compared with males, females (with and without autism) do better in assessments of processing speed, cognitive flexibility, verbal learning and memory and semantic fluency. Our results suggest that although females show different cognitive performance to males, these sex differences were not specific to the group with a diagnosis of autism.

Disability, functioning, and quality of life among treatment-seeking young autistic adults and its relation to depression, anxiety, and stress / S. H. PARK in Autism, 23-7 (October 2019)  

Public ISBD [article]  inAutism > 23-7 (October 2019) . - p.1675-1686 Titre : Disability, functioning, and quality of life among treatment-seeking young autistic adults and its relation to depression, anxiety, and stress Type de document : Texte imprimé et/ou numérique Auteurs : S.

This group was compared to young adults presenting to the same service with primary mental health disorders (depression, n = 343; bipolar, n = 132; psychosis, n = 166; and anxiety, n = 303). This study also investigated the influence of mood symptoms on general health and functioning in the autism spectrum disorder group. Young autistic adults reported significant general health and functioning impairments that were of similar degree to those presenting with primary mental health disorders. Interestingly, the autistic group also reported similarly high levels of mood symptoms to those with primary depressive and anxiety disorders. In the autistic group, depressive symptoms were strongly associated with distress, quality of life, and work loss days, while stress symptoms were strongly associated with disability. This study highlights further research, and mental health services are required specifically targeting young autistic adults to address their significant unmet needs.

Reduced heart rate variability in adults with autism spectrum disorder / R. THAPA in Autism Research, 12-6 (June 2019)  

Public ISBD [article]  inAutism Research > 12-6 (June 2019) . - p.922-930 Titre : Reduced heart rate variability in adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R.

GUASTELLA, Auteur Année de publication : 2019 Article en page(s) : p.922-930 Langues : Anglais (eng) Mots-clés : autonomic nervous system  biological marker  heart rate variability  mental health  parasympathetic nervous system  social development  sympathetic nervous system Index. décimale : PER Périodiques Résumé : A growing body of research has suggested heart rate variability (HRV) may be reduced in autism spectrum disorder (ASD) in comparison to neurotypical cohorts. While there have been several studies investigating HRV in children diagnosed with ASD, few studies have been conducted in adults. The objective of the current study was to investigate autonomic nervous system activity as assessed by HRV in adults diagnosed with ASD. We hypothesized that adults with ASD would show a reduction in HRV compared to neurotypical participants. Participants diagnosed with ASD (n = 55) were recruited from the Autism Clinic for Translational Research at the Brain and Mind Centre (University of Sydney) between 2013 and 2017. Neurotypical participants were recruited from advertisements and online media. Resting state heart rate was measured for 5 min while participants sat in an upright position. Results showed there was an overall significant difference in resting-state HRV between adults diagnosed with ASD compared to the neurotypical control group. Logarithmically transformed high frequency (HF) and root mean square of successive differences were particularly decreased in the ASD group, suggesting lower parasympathetic activity. The use of psychotropic medications and comorbidities were associated with reductions in low frequency of HRV. Our data suggest an overall dysregulation in resting autonomic activity in adults with ASD. This may represent an important physiological mechanism leading to potential cardiovascular risk in ASD, which warrants further investigation. Autism Res 2019, 12: 922-930. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: ASD is commonly associated with a range of physical and mental health comorbidities. Autonomic disruptions underlying reductions in heart rate variability (HRV) have been linked to a range of mental and physical health conditions. We assessed resting-state HRV in adults diagnosed with ASD in comparison to healthy individuals. Our results showed reduced heart rate variability in people diagnosed with ASD compared to adults without ASD. These findings implicate a role for autonomic activity as a potentially modifiable risk factor for ASD.

Validation of the 36-item and 12-item self-report World Health Organization Disability Assessment Schedule II (WHODAS-II) in individuals with autism spectrum disorder / S. H. PARK in Autism Research, 12-7 (July 2019)

However, its psychometric properties have not been explored extensively in individuals with autism spectrum disorder (ASD). This study examined the psychometric properties of the 36-item and 12-item Self-Report WHODAS-II from 109 individuals diagnosed with ASD and without intellectual disability (IQ >/= 70). Participants were consecutively recruited from the Brain and Mind Centre in New South Wales, Australia. The WHODAS-II showed adequate internal consistency for all domain scores (alpha = 0.78-0.97 for 36-item) and for the summary scale (alpha = 0.95 for 36-item; 0.86 for 12-item). All items also exhibited satisfactory correlations with their respective domain (r = 0.39-0.94 for 36-item) and summary scores (r = 0.42-0.71 for 36-item; 0.42-0.67 for 12-item), except item 4.5 "sexual activity" from the 36-item WHODAS-II (r = 0.19). Concurrent validity was shown by moderate correlations between similar constructs across the WHODAS-II and the World Health Organization Quality of Life BREF (Ps < 0.05). The second-order 7-factor model showed the best fit for the 36-item WHODAS-II, while the second-order 6-factor model demonstrated an acceptable fit for the 12-item WHODAS-II. The model fit could be improved with some modifications. The Schmid-Leiman transformation further confirmed the appropriateness of the second-order factor structure. Overall, the results indicated that the WHODAS-II is a viable generic self-report measure for disability in autistic individuals without ID. Autism Res 2019, 12: 1101-1111. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: The majority of autistic people have a disability with a profound or severe limitation in their core activities. However, there is currently limited research identifying reliable and valid self-report measures for disability in the autistic population. This study examined the psychometric properties of the World Health Organization Disability Assessment Schedule II (WHODAS-II) from 109 autistic individuals without intellectual disability. Our results suggest that the WHODAS-II is a viable generic self-report measure for disability in autistic individuals.
