Method Data were aggregated for toddlers aged 14?36 months who participated in previous studies or completed clinical screening. An item with < 30% of endorsements was classified as low endorsement, an item falling within the range of 30?60% as moderate endorsement, and an item with > 60% as high endorsement. Results All items had a low endorsement rate in at least one country and moderate to high in others. Of 20 items, 14 had a moderate to high endorsement rate in seven to nine countries. Of particular relevance are items with moderate to high endorsement rates in all countries excluding Malaysia, such as points to get help, points to show, brings things to show, follows a point, follows your gaze, and understands what is said. On the other hand, makes eye contact, responds to name, hearing concerns, and reciprocal smile were interpreted differently across the countries. Conclusions This study showed differences in parent/caregiver responding to M-CHAT(-R) items across ten countries, which may indicate cross-country variations in the recognition and evaluation of autistic symptoms in toddlers. Items related to joint attention, social engagement, and language comprehension were reported in a similar manner across countries and could be interpreted as universal autistic symptoms in toddlers.

Quantitative Checklist for Autism in Toddlers (Q-CHAT): A psychometric study with Serbian Toddlers / Dejan STEVANOVIC in Research in Autism Spectrum Disorders, 83 (May 2021)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 83 (May 2021) . - 101760 Titre : Quantitative Checklist for Autism in Toddlers (Q-CHAT): A psychometric study with Serbian Toddlers Type de document : Texte imprimé et/ou numérique Auteurs : Dejan STEVANOVIC, Auteur Article en page(s) : 101760 Langues : Anglais (eng) Mots-clés : Early screening  ASD  Instrument  Cross-cultural  Autistic traits Index. décimale : PER Périodiques Résumé : Background The present study evaluated the underlying structure of the Quantitative Checklist for Autism in Toddlers (Q-CHAT) in a Serbian sample and its measurement properties for community-based screening. Method Data were collected from parents of 220 toddlers aged 15–36 months. The parents completed together the Q-CHAT and the Modified Checklist for Autism in Toddlers - Revised (M-CHAT-R). Confirmatory factor analysis (CFA), internal consistency, convergent and known-groups validity were analyzed, with sensitivity, specificity, and predictive values calculated. Results From CFA, 17 out of 25 items emerged to represent three underlying factors, namely social communication/interaction, restrictive/repetitive behavior, and language impairment. The Q-CHAT-10 was found to have one-dimensional structure. Cronbach’s ? was ?.81 for Q-CHAT scores. All scores for toddlers with typical development were significantly lower compared to those with ASD. The cut-off points that best-balanced sensitivity/specificity for the total scores, were 37 for the Q-CHAT with all 25 items (96.2/81.9 %), 26 for the Q-CHAT with 17 items (96.2/93.3 %), and 3 (100/93.3 %) for the Q-CHAT-10, with the positive/negative predictive values of .39/.99, .57/1.00, and .67/1.00, respectively. Conclusions The Serbian Q-CHAT versions with 10 and 17 items showed sound internal consistency, convergent and know-groups validity, and high levels of sensitivity and specificity for community-based screening. A multidimensional structure with social communication/interaction, restrictive/repetitive behaviors, and language impairment aspects was confirmed. This implies that autistic traits in toddlers could be measured dimensionally with the Q-CHAT, but its structure should be verified in additional studies.
