Titre : Autism Screening in the First Year and Beyond: Comparison of Multiple Measures Type de document : texte imprimé Auteurs : Devon N. GANGI, Auteur ; Chandni PARIKH, Auteur ; Monique Moore HILL, Auteur ; Shyeena MAQBOOL, Auteur ; Rachel NI, Auteur ; Simon DVORAK, Auteur ; Gregory S. YOUNG, Auteur ; Sally OZONOFF, Auteur Année de publication : 2026 Article en page(s) : p.e70340 Langues : Anglais (eng) Mots-clés : autism early detection psychometric properties screening Index. décimale : PER Périodiques Résumé : ABSTRACT Autism screening aids in early detection and diagnosis. Several screeners are available for toddlers 16?months and older, but there is little data on the accuracy of screening measures used in the first year of life. A community sample (N?=?1641) completed three screeners?M-CHAT-R, ITC, VIRSA?online at 6, 9, 12, 18, and 24?months of age (including exploratory use of M-CHAT-R prior to 16?months). At 36?months, outcomes of ASD or Non-ASD were determined by tele-evaluation and outcome surveys. Psychometric properties were assessed for all screeners at all ages, both used individually and in combination. When used in the first year of life (6?12?months), psychometric properties were in the poor range, with area under the curve (AUC) 0.70 for all three screeners, whether used in isolation or combination. At 18 and 24?months, the M-CHAT-R and ITC outperformed the VIRSA, with psychometric properties in the fair range (AUC 0.70?0.79) used in isolation and the good range (AUC ≥?0.80) when used in combination. Using the M-CHAT-R and ITC at more than one age in the second year also fell in the good range. This study, using procedures to address limitations of prior screening studies and follow screen-negative cases, found that none of the three screeners had adequate psychometric properties in the first year. At 18 and 24?months, findings supported the use of multiple screeners, either in combination or longitudinally, for best prediction of autism diagnosis.

Titre : A video-based measure to identify autism risk in infancy Type de document : texte imprimé Auteurs : Gregory S. YOUNG, Auteur ; John N. CONSTANTINO, Auteur ; Simon DVORAK, Auteur ; Ashleigh BELDING, Auteur ; Devon N. GANGI, Auteur ; Alesha HILL, Auteur ; Monique HILL, Auteur ; Meghan MILLER, Auteur ; Chandni PARIKH, Auteur ; A.J. SCHWICHTENBERG, Auteur ; Erika SOLIS, Auteur ; Sally OZONOFF, Auteur Article en page(s) : p.88-94 Langues : Anglais (eng) Mots-clés : Autism infancy screening social development Index. décimale : PER Périodiques Résumé : BACKGROUND: Signs of autism are present in the first 2 years of life, but the average age of diagnosis lags far behind. Instruments that improve detection of autism risk in infancy are needed. This study developed and tested the psychometric properties of a novel video-based approach to detecting ASD in infancy. METHODS: A prospective longitudinal study of children at elevated or lower risk for autism spectrum disorder was conducted. Participants were 76 infants with an older sibling with ASD and 37 infants with no known family history of autism. The Video-referenced Infant Rating System for Autism (VIRSA) is a web-based application that presents pairs of videos of parents and infants playing together and requires forced-choice judgments of which video is most similar to the child being rated. Parents rated participants on the VIRSA at 6, 9, 12, and 18 months of age. We examined split-half and test-retest reliability; convergent and discriminant validity; and sensitivity, specificity, and negative and positive predictive value for concurrent and 36-month ASD diagnoses. RESULTS: The VIRSA demonstrated satisfactory reliability and convergent and discriminant validity. VIRSA ratings were significantly lower for children ultimately diagnosed with ASD than children with typical development by 12 months of age. VIRSA scores at 18 months identified all children diagnosed with ASD at that age, as well as 78% of children diagnosed at 36 months. CONCLUSIONS: This study represents an initial step in the development of a novel video-based approach to detection of ASD in infancy. The VIRSA's psychometric properties were promising when used by parents with an older affected child, but still must be tested in community samples with no family history of ASD. If results are replicated, then the VIRSA's low-burden, web-based format has the potential to reduce disparities in communities with limited access to screening.
