Titre : Autism screening at 18 months of age: a comparison of the Q-CHAT-10 and M-CHAT screeners Type de document : Texte imprimé et/ou numérique Auteurs : R. STURNER, Auteur ; B. HOWARD, Auteur ; P. BERGMANN, Auteur ; S. ATTAR, Auteur ; L. STEWART-ARTZ, Auteur ; K. BET, Auteur ; Carrie ALLISON, Auteur ; Simon BARON-COHEN, Auteur Article en page(s) : 2p. Langues : Anglais (eng) Mots-clés : Autism screening Developmental screening M-chat Q-CHAT Primary Care and its for-profit subsidiary, CHADIS, Inc. CHADIS, the web-tool used in the study was developed by Dr. Sturner and his spouse, Dr. Howard. Dr. Sturner is Director of the Center and Dr. Howard is President of CHADIS, Inc. Both are members of the Board of Directors of Center and are paid employees or consultants to both entities.

Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism screening is recommended at 18- and 24-month pediatric well visits. The Modified Checklist for Autism in Toddlers-Revised (M-CHAT-R) authors recommend a follow-up interview (M-CHAT-R/F) when positive. M-CHAT-R/F may be less accurate for 18-month-olds than 24-month-olds and accuracy for identification prior to two years is not known in samples that include children screening negative. Since autism symptoms may emerge gradually, ordinally scoring items based on the full range of response options, such as in the 10-item version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT-10), might better capture autism signs than the dichotomous (i.e., yes/no) items in M-CHAT-R or the pass/fail scoring of Q-CHAT-10 items. The aims of this study were to determine and compare the accuracy of the M-CHAT-R/F and the Q-CHAT-10 and to describe the accuracy of the ordinally scored Q-CHAT-10 (Q-CHAT-10-O) for predicting autism in a sample of children who were screened at 18 months. METHODS: This is a community pediatrics validation study with screen positive (n?=?167) and age- and practice-matched screen negative children (n?=?241) recruited for diagnostic evaluations completed prior to 2 years old. Clinical diagnosis of autism was based on results of in-person diagnostic autism evaluations by research reliable testers blind to screening results and using the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) Toddler Module and Mullen Scales of Early Learning (MSEL) per standard guidelines. RESULTS: While the M-CHAT-R/F had higher specificity and PPV compared to M-CHAT-R, Q-CHAT-10-O showed higher sensitivity than M-CHAT-R/F and Q-CHAT-10. LIMITATIONS: Many parents declined participation and the sample is over-represented by higher educated parents. Results cannot be extended to older ages. CONCLUSIONS: Limitations of the currently recommended two-stage M-CHAT-R/F at the 18-month visit include low sensitivity with minimal balancing benefit of improved PPV from the follow-up interview. Ordinal, rather than dichotomous, scoring of autism screening items appears to be beneficial at this age. The Q-CHAT-10-O with ordinal scoring shows advantages to M-CHAT-R/F with half the number of items, no requirement for a follow-up interview, and improved sensitivity. Yet, Q-CHAT-10-O sensitivity is less than M-CHAT-R (without follow-up) and specificity is less than the two-stage procedure. Such limitations are consistent with recognition that screening needs to recur beyond this age.

This report describes the five virtual instruments available at the time of manuscript development for use by experienced clinicians making diagnostic determinations of ASD for toddlers across the 12- to 36-months age range. We focus on synchronous virtual assessments in which clinicians guide the child's caregiver through a range of assessment activities and observe spontaneous and elicited behaviors. Assessments are compared on dimensions of targeted behavioral domains, specific activities and presses employed, scoring approaches, and other key logistical considerations to guide instrument selection for use in varied clinical and research contexts.
