Do Parents and Clinicians Agree on Ratings of Autism-Related Behaviors at 12 Months of Age? A Study of Infants at High and Low Risk for ASD / S. L. MACARI in Journal of Autism and Developmental Disorders, 48-4 (April 2018)

Similar items were compared from the First Year Inventory (Baranek et al. First-Year Inventory (FYI) 2.0. University of North Carolina, Chapel Hill, 2003), a parent screener for ASD, and the ADOS-2 Toddler Module (Lord et al. 2013), a standardized ASD diagnostic tool. Measures were administered concurrently to 12-month-olds at high and low risk for ASD. Results suggest that clinicians and parents rated behaviors similarly. In addition, both informants rated high-risk infants as more impaired in several social-communication behaviors. Furthermore, the format of questions impacted agreement across observers. These findings have implications for the development of a new generation of screening instruments for ASD.

Operationalizing atypical gaze in toddlers with autism spectrum disorders: a cohesion-based approach / Q. WANG in Molecular Autism, 9 (2018)  

Public ISBD [article]  inMolecular Autism > 9 (2018) . - 25p. Titre : Operationalizing atypical gaze in toddlers with autism spectrum disorders: a cohesion-based approach Type de document : Texte imprimé et/ou numérique Auteurs : Q. WANG, Auteur ; Daniel J. CAMPBELL, Auteur ; S. L. MACARI, Auteur ; Katarzyna CHAWARSKA, Auteur ; F. SHIC, Auteur Article en page(s) : 25p. Langues : Anglais (eng) Mots-clés : Attention  Autism Spectrum Disorder/diagnosis/physiopathology  Case-Control Studies  Child, Preschool  Female  Fixation, Ocular  Humans  Infant  Male  Social Behavior  Visual Perception  asd  Attentional synchrony  Atypicality  Autism  Cohesion  Eye tracking  Visual attention Index. décimale : PER Périodiques Résumé : Background: Multiple eye-tracking studies have highlighted the "atypical" nature of social attention in autism. However, it is unclear how "atypical" or "typical" should be quantified. Methods: We developed a method for identifying moments when members of a group looked at similar places (High-Cohesion Time Frames; HCTFs). We defined typicality as the proximity of gaze points to typically developing (TD) gaze points during TD HCTFs. Comparing toddlers with ASD (n = 112) to developmentally delayed (DD, n = 36) and TD (n = 163) toddlers during a video with Dyadic Bid, Sandwich-Making, Joint Attention, and Animated Toys conditions, we examined (a) individual typicality scores, (b) the relationship between typicality and symptom severity, and (c) HCTF distributions associated with each diagnostic group. Results: The ASD group had lower gaze typicality scores compared to the TD and DD groups in the Dyadic Bid and Sandwich-Making conditions but not during Animated Toys. The DD and TD groups did not differ in any condition. Correlational analyses indicated that higher typicality scores were associated with increased looking at pre-planned locations of the scene indexed by each experimental condition. In the ASD group, lower gaze typicality was associated with more severe autism symptoms. Examining ASD HCTFs, the gaze of toddlers with ASD was least cohesive during Dyadic Bid and most cohesive during Animated Toys. Conclusion: In contrast to non-ASD groups, toddlers with ASD show high cohesion during salient nonsocial events, suggesting that consistency in looking strategies may depend more on perceptual features. These findings are consequential for understanding individual differences in visual attention in ASD and for the design of more sensitive biomarker tasks for stratification, between-group differentiation, and measuring response to treatment.
