Psychometric properties, factor structure and cross-cultural validity of the quantitative CHecklist for autism in toddlers (Q-CHAT) in an Italian community setting / Liliana RUTAA in Research in Autism Spectrum Disorders, 64 (August 2019)

Titre : Psychometric properties, factor structure and cross-cultural validity of the quantitative CHecklist for autism in toddlers (Q-CHAT) in an Italian community setting Type de document : Texte imprimé et/ou numérique Auteurs : Liliana RUTAA, Auteur ; Giuseppe Maurizio ARDUINO, Auteur ; Antonella GAGLIANO, Auteur ; Fabio APICELLA, Auteur ; Elisa LEONARDI, Auteur ; Francesca I.

Methods A group of n?=?2400 unselected Italian toddlers were screened by paediatricians during routine well?CHild visits between 18 and 24 months,in three Italian regions, representative of the North, Centre and South of Italy. The psychometric properties and factor structure of the Q?CHAT were explored and compared with published literature from Asia and the UK. Results The total Q?CHAT scores in our sample confirmed a normal distribution. Mean Q?CHAT scores across regions were consistent with those reported in UK studies and likewise, a gender effect was found, with boys scoring higher than girls.We also found a remarkable consistency with the three-factor structure of the Asian Q?CHAT. Internal consistency was acceptable for both the Q?CHAT total score and the three factors. Conclusions Our results confirm the dimensional distribution of autistic traits and related symptoms in unselected populations across different cultures. The Q?CHAT is a valid and reliable dimensional screening instrument to be used within a routine paediatric setting during well-child assessments.The main normative data and factor structure replicated in our sample En ligne : https://doi.org/10.1016/j.rasd.2019.04.004 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=399

However, it is still unclear whether ASD symptoms are measured the same way across different societies and world regions with this tool, since data on its cross-cultural validity are lacking. This study evaluated the cross-cultural measurement invariance of the CARS among children with ASD from six countries, for whom data were aggregated from previous studies in India (n = 101), Jamaica (n = 139), Mexico (n = 72), Spain (n = 99), Turkey (n = 150), and the United States of America (n = 186). We analyzed the approximate measurement invariance based on Bayesian structural equation modeling. The model did not fit the data and its measurement invariance did not hold, with all items found non-invariant across the countries. Items related to social communication and interaction (i.e., relating to people, imitation, emotional response, and verbal and nonverbal communication) displayed lower levels of cross-country non-invariance compared to items about stereotyped behaviors/sensory sensitivity (i.e., body and object use, adaptation to change, or taste, smell, and touch response). This study found that the CARS may not provide cross-culturally valid ASD assessments. Thus, cross-cultural comparisons with the CARS should consider first which items operate differently across samples of interest, since its cross-cultural measurement non-invariance could be a source of cross-cultural variability in ASD presentations. Additional studies are needed before drawing valid recommendations in relation to the cultural sensitivity of particular items.
