Representativeness of autistic samples in studies recruiting through social media / Eya-Mist RØDGAARD in Autism Research, 15-8 (August 2022)
[article]
Titre : Representativeness of autistic samples in studies recruiting through social media Type de document : Texte imprimé et/ou numérique Auteurs : Eya-Mist RØDGAARD, Auteur ; Kristian JENSEN, Auteur ; Kamilla Woznica MISKOWIAK, Auteur ; Laurent MOTTRON, Auteur Article en page(s) : p.1447-1456 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/epidemiology Autistic Disorder Humans Intellectual Disability/epidemiology Social Media Surveys and Questionnaires autism online recruitment sampling bias selection bias Index. décimale : PER Périodiques Résumé : Survey-based research with recruitment through online channels is a convenient way to obtain large samples and has recently been increasingly used in autism research. However, sampling from online channels may be associated with a high risk of sampling bias causing findings not to be generalizable to the autism population. Here we examined autism studies that have sampled on social media for markers of sampling bias. Most samples showed one or more indicators of sampling bias, in the form of reversed sex ratio, higher employment rates, higher education level, lower fraction of individuals with intellectual disability, and later age of diagnosis than would be expected when comparing with for example population study results from published research. Findings from many of the included studies are therefore difficult to generalize to the broader autism population. Suggestions for how research strategies may be adapted to address some of the problems are discussed. LAY SUMMARY: Online surveys offer a convenient way to recruit large numbers of participants for autism research. However, the resulting samples may not fully reflect the autism population. Here we investigated the samples of 36 autism studies that recruited participants online and found that the demographic composition tended to deviate from what has been reported about the autism population in previous research. The results may thus not be generalizable to autism in general.

Titre : Searching for What Really Matters: A Thematic Analysis of Quality of Life among Preschool Children on the Autism Spectrum Type de document : Texte imprimé et/ou numérique Auteurs : Jérôme LICHTLE, Auteur ; Kristopher LAMORE, Auteur ; Amandine PEDOUX, Auteur ; Naomi DOWNES, Auteur ; Laurent MOTTRON, Auteur ; Emilie CAPPE, Auteur Article en page(s) : p.2098-2111 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/diagnosis Autistic Disorder Child Child Development Disorders, Pervasive Child, Preschool Early Intervention, Educational Humans Quality of Life Autism spectrum disorder Children Preschool Thematic analysis Index. décimale : PER Périodiques Résumé : Quality of life (QoL) is an essential measure when assessing health interventions. Most early interventions for preschool children on the spectrum evaluate the effects on autism symptoms. However, researchers increasingly believe that good interventions should also improve the QoL of these children. Domains of QoL among preschool children on the autism spectrum have not previously been researched. We interviewed adults on the spectrum to explore early childhood experiences that made their lives satisfying. Our data revealed four major themes: interests, environmental regularity, sensory differences and social interactions. This study provides the first insights on aspects of life important to pre-schoolers on the spectrum. Findings will contribute to developing items for a measure of QoL among this population.

[article]
Titre : Sex differences in brain plasticity: a new hypothesis for sex ratio bias in autism Type de document : Texte imprimé et/ou numérique Auteurs : Laurent MOTTRON, Auteur ; Pauline DURET, Auteur ; Sophia MUELLER, Auteur ; Robert D. MOORE, Auteur ; Baudouin FORGEOT D'ARC, Auteur ; Sebastien JACQUEMONT, Auteur ; Lan XIONG, Auteur Article en page(s) : p.1-19 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Several observations support the hypothesis that differences in synaptic and regional cerebral plasticity between the sexes account for the high ratio of males to females in autism. First, males are more susceptible than females to perturbations in genes involved in synaptic plasticity. Second, sex-related differences in non-autistic brain structure and function are observed in highly variable regions, namely, the heteromodal associative cortices, and overlap with structural particularities and enhanced activity of perceptual associative regions in autistic individuals. Finally, functional cortical reallocations following brain lesions in non-autistic adults (for example, traumatic brain injury, multiple sclerosis) are sex-dependent. Interactions between genetic sex and hormones may therefore result in higher synaptic and consecutively regional plasticity in perceptual brain areas in males than in females. The onset of autism may largely involve mutations altering synaptic plasticity that create a plastic reaction affecting the most variable and sexually dimorphic brain regions. The sex ratio bias in autism may arise because males have a lower threshold than females for the development of this plastic reaction following a genetic or environmental event.
