Alexithymia and Autistic Traits as Contributing Factors to Empathy Difficulties in Preadolescent Children / L. G. SPEYER in Journal of Autism and Developmental Disorders, 52-2 (February 2022)

Empathy, alexithymia and autistic traits have yet to be examined concurrently in children. Therefore, we examined the co-occurrence of empathy difficulties and alexithymia in 59 typically developing and 5 autistic children. Multiple measures (self-report, parent-report and a behavioural task) were used to evaluate empathy and to assess differences in self- and parent-reports using multiple regressions. Alexithymia was found to predict empathy significantly better than autistic traits, providing support for the alexithymia hypothesis. From a therapeutic perspective, results suggest autistic children who screen positive for elevated alexithymic traits may benefit from additional support targeting emotion identification.

Alexithymia in children with and without autism spectrum disorders / Cáit GRIFFIN in Autism Research, 9-7 (July 2016)  

Public ISBD [article]  inAutism Research > 9-7 (July 2016) . - p.773-780 Titre : Alexithymia in children with and without autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Cáit GRIFFIN, Auteur ; Michael V. LOMBARDO, Auteur ; Bonnie AUYEUNG, Auteur Article en page(s) : p.773-780 Langues : Anglais (eng) Mots-clés : autism  alexithymia  parent-report  self-report  autistic traits  children Index. décimale : PER Périodiques Résumé : Alexithymia refers to pronounced difficulty in identifying and describing one's own emotions and is associated with an externally oriented focus of thinking. Alexithymia is known to be much more common in adults with autism spectrum disorders (ASD) compared with the typically developing (TD) adult population. However, we know very little about alexithymia in young children with ASD and advancing our understanding of this topic may be of critical clinical and translational importance. Here, we present the first study to examine alexithymia in children with ASD. We find that alexithymia is substantially elevated in ASD on both self- and parent-report measures. Despite both measures being sensitive to on-average group differentiation, we find no evidence of correlation between such measures, indicating that children and their parents may be using different sources of information. Parent-rated alexithymia is also associated with increasing levels of autistic traits. Discrepancy between self and other alexithymia ratings are also associated with autistic traits, but only in ASD. These results underscore the idea that assessing alexithymia in ASD at younger ages may help identify important subgroups that have particular difficulties in the domain of emotion processing.

Attitudes of the autism community to early autism research / Sue FLETCHER-WATSON in Autism, 21-1 (January 2017)

This work invokes specific ethical concerns such as use of ‘at-risk’ language, communicating study findings to parents and the future perspective of enrolled infants when they reach adulthood. This study aimed to ground this research field in an understanding of the perspectives of members of the autism community. Following focus groups to identify topics, an online survey was distributed to autistic adults, parents of children with autism and practitioners in health and education settings across 11 European countries. Survey respondents (n?=?2317) were positively disposed towards early autism research, and there was significant overlap in their priorities for the field and preferred language to describe infant research participants. However, there were also differences including overall less favourable endorsement of early autism research by autistic adults relative to other groups and a dislike of the phrase ‘at-risk’ to describe infant participants, in all groups except healthcare practitioners. The findings overall indicate that the autism community in Europe is supportive of early autism research. Researchers should endeavour to maintain this by continuing to take community perspectives into account.

Autism prevalence in China is comparable to Western prevalence / X. SUN in Molecular Autism, 10 (2019)  

Public ISBD [article]  inMolecular Autism > 10 (2019) . - 7 p. Titre : Autism prevalence in China is comparable to Western prevalence Type de document : Texte imprimé et/ou numérique Auteurs : X.

Langues : Anglais (eng) Mots-clés : *Autism  *Children  *China  *Diagnosis  *Prevalence  *Screening  University of Hong Kong and the Peking University Institutional Review Board.  Consent was provided to participants via the screening package before  participating. Participants were asked to indicate whether they continued to  consent at the end of the study.Not applicable.The authors declare that they have  no competing interests.Springer Nature remains neutral with regard to  jurisdictional claims in published maps and institutional affiliations. Index. décimale : PER Périodiques Résumé : Background: Autism prevalence in the West is approximately 1% of school age children. Autism prevalence in China has been reported to be lower than in the West. This is likely due to at least two reasons: (1) most studies in China only included the special school population, overlooking the mainstream school population; and (2) most studies in China have not used contemporary screening and diagnostic methods. To address this, we tested total autism prevalence (mainstream and special schools) in Jilin City, and mainstream school autism prevalence in Jiamusi and Shenzhen cities. Methods: The study included a three-step process: (1) screening; (2) clinical assessment of 'screen positives' plus controls; and (3) research diagnostic assessment of those meeting clinical threshold for concerns at step 2. Prevalence estimates per 10,000 children aged 6-10 years old were weighted for study design using diagnostic criteria applied at the research assessment stage. Results: In Jilin City, 77 cases of autism were identified from a total population of 7258, equating to a prevalence of 108 per 10,000 (95% confidence interval (CI) 89, 130). In Shenzhen City: 21,420 children were screened and 35 cases of autism were identified, resulting in a mainstream prevalence of 42 per 10,000 (95% CI 20-89). In Jiamusi City, 16,358 children were screened, with 10 autism cases being identified, with a mainstream prevalence of 19 per 10,000 (95% CI 10-38). Conclusions: Results from Jilin City, where both mainstream and special school data were available, revealed a similar prevalence of autism in China to the West, at around 1%. Results from Shenzhen and Jiamusi cities, where only mainstream data were available, prevalence is also in line with Western estimates. In all three cities, new cases of autism were identified by the study in mainstream schools, reflecting current under-diagnosis. Non-significant variation across different cities is seen indicating the need to explore potential variation of autism across diverse Chinese regions with large sample sizes to achieve a fully robust national picture.

We sought to directly measure the occurrence of autism traits in a cohort of individuals with AgCC and to investigate the neural underpinnings of this association. We screened a large AgCC cohort (n = 106) with the Autism Spectrum Quotient (AQ) and found that 45 % of children, 35 % of adolescents, and 18 % of adults exceeded the predetermined autism-screening cut-off. Interestingly, performance on the AQ’s imagination domain was inversely correlated with magnetoencephalography measures of resting-state functional connectivity in the right superior temporal gyrus. Individuals with AgCC should be screened for ASD and disorders of the corpus callosum should be considered in autism diagnostic evaluations as well.
