Assessing general and autism-relevant quality of life in autistic adults: A psychometric investigation using item response theory / Zachary J WILLIAMS in Autism Research, 14-8 (August 2021)  

Public ISBD [article]  inAutism Research > 14-8 (August 2021) . - p.1633-1644 Titre : Assessing general and autism-relevant quality of life in autistic adults: A psychometric investigation using item response theory Type de document : texte imprimé Auteurs : Zachary J WILLIAMS, Auteur ; Katherine GOTHAM, Auteur Article en page(s) : p.1633-1644 Langues : Anglais (eng) Mots-clés : Adult  Autism Spectrum Disorder  Autistic Disorder  Female  Humans  Male  Psychometrics  Quality of Life  Sexism  Surveys and Questionnaires  ASQoL  autism  differential item functioning  item response theory  measurement invariance  quality of life  reliability  sex differences  validity  well-being  Roche. He also serves on the family advisory committee of the Autism Speaks Autism  Treatment Network Vanderbilt site and the autistic researcher review board of the  Autism Intervention Research Network on Physical Health (AIR-P). Katherine Gotham  has no conflicts of interest to disclose. Index. décimale : PER Périodiques Résumé : Although many interventions and services for autistic people have the ultimate goal of improving quality of life (QoL), there is relatively little research on how best to assess this construct in the autistic population, and existing scales designed for non-autistic individuals may not assess all meaningful facets of QoL in the autistic population. To address this need, the autism spectrum QoL form (ASQoL) was recently developed as a measure of the autism-relevant quality of life. However, the psychometrics of the ASQoL have not been examined beyond the authors' initial validation study, and important properties such as measurement invariance/differential item functioning (DIF) have not yet been tested. Using data from 700 autistic adults recruited from the Simons Foundation's SPARK cohort, the current study sought to perform a comprehensive independent psychometric evaluation of the ASQoL using item response theory, comparing its performance to a newly-proposed brief measure of general QoL (the WHOQOL-4). Our models revealed substantial DIF by sex and gender in the ASQoL, which caused ASQoL scores to grossly underestimate the self-reported QoL of autistic women. Based on a comparison of latent variable means, we demonstrated that observed sex/gender differences in manifest ASQoL scores were the result of statistical artifacts, a claim that was further supported by the lack of significant group differences on the sex/gender-invariant WHOQOL-4. Our findings indicate that the ASQoL composite score is psychometrically problematic in its current form, and substantial revisions may be necessary before valid and meaningful inferences can be made regarding autism-relevant aspects of QoL. LAY SUMMARY: Quality of life (QoL) is an extremely important outcome for autistic people, but many of the tools that are used to measure it does not take into account how QoL may be different for autistic people. Using data from 700 autistic adults, we examined the measurement properties of the autism spectrum quality of life form (ASQoL), a new measure of QoL designed specifically for autistic people. Our results indicate that the ASQoL shows a pronounced sex/gender bias, which causes it to underestimate QoL in autistic women. This bias needs to be eliminated before the ASQoL can be successfully used to measure QoL in the autistic population.

In this study, electronic medical records of 579 autistic individuals and 1897 matched controls prior to age 2 were analyzed for potential predictive conditions. Using a novel tool, the relative association of each condition in the autistic group was compared to the control group using logistic regressions across medical records. Generalized convulsive epilepsy, nystagmus, lack of normal physiological development, delayed milestones, and strabismus were more likely in those later diagnosed with ASD while perinatal jaundice was less likely to be associated. Lesser-known conditions, such as strabismus and nystagmus, may point to novel predictive co-occurring condition profiles which could improve screening practices for ASD.

Characterizing Interoceptive Differences in Autism: A Systematic Review and Meta-analysis of Case-control Studies / Zachary J. WILLIAMS in Journal of Autism and Developmental Disorders, 53-3 (March 2023)

The current study systematically reviewed and meta-analyzed the extant literature comparing interoceptive outcomes between autistic (AUT) and neurotypical (NT) individuals, determining which domains of interoception demonstrate robust between-group differences. A three-level Bayesian meta-analysis compared heartbeat counting performance, heartbeat discrimination performance, heartbeat counting confidence ratings, and self-reported interoceptive attention between AUT and NT groups (15 studies; nAUT=467, nNT=478). Autistic participants showed significantly reduced heartbeat counting performance [g=? 0.333, CrI95% (? 0.535, ? 0.138)] and higher confidence in their heartbeat counting abilities [g=0.430, CrI95% (0.123, 0.750)], but groups were equivalent on other meta-analyzed outcomes. Implications for future interoception research in autism are discussed.
