Comparing traditional and continuous norming models for neurobehavioral assessments: A simulation study / Thomas W. FRAZIER in Research in Autism, 137 (September 2026)  

Public ISBD [article]  inResearch in Autism > 137 (September 2026) . - 202987 Titre : Comparing traditional and continuous norming models for neurobehavioral assessments: A simulation study Type de document : texte imprimé Auteurs : Thomas W. FRAZIER, Auteur ; Eric A. YOUNGSTROM, Auteur ; Knaebel BEN, Auteur ; Mirko ULJAREVIĆ, Auteur Article en page(s) : 202987 Langues : Anglais (eng) Mots-clés : Continuous norming  Generalized additive models  Simulation  Sample size  Test development Index. décimale : PER Périodiques Résumé : Developing accurate test norms is crucial to developmental disability practice but requires substantial resources. Continuous norms show promise relative to traditional norms, yet there is limited guidance on optimal methods and minimum sample sizes. This simulation study compared traditional norming with continuous norming models across 96 data conditions varying in sample size (500−1500), age trajectories (ages 2–22), variance patterns, and skewness. Generalized Additive Models for Location, Scale, and Shape (GAMLSS) that approximated the data generating conditions tended to be the best fitting models. Best fitting GAMLSS models showed closer fit to the data at N = 500 than traditional windowing norms at N = 1500 with the largest GAMLSS performance gains occurring by N = 750. Real-world neurobehavioral data supported the need for an iterative model selection process when developing continuous norms. Test developers can achieve high norming accuracy with smaller samples using a GAMLSS model selection process, potentially reducing costs while improving precision.

Comparison of Autism Screening in Younger and Older Toddlers / Raymond STURNER in Journal of Autism and Developmental Disorders, 47-10 (October 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-10 (October 2017) . - p.3180-3188 Titre : Comparison of Autism Screening in Younger and Older Toddlers Type de document : texte imprimé Auteurs : Raymond STURNER, Auteur ; Barbara HOWARD, Auteur ; Paul BERGMANN, Auteur ; Lydia STEWART, Auteur ; Talin E. AFARIAN, Auteur Article en page(s) : p.3180-3188 Langues : Anglais (eng) Mots-clés : Autism screening  M-CHAT  Developmental screening  Test development Index. décimale : PER Périodiques Résumé : This study examined the effect of age at completion of an autism screening test on item failure rates contrasting older (>20 months) with younger (<20 months) toddlers in a community primary care sample of 73,564 children. Items related to social development were categorized into one of three age sets per criteria from Inada et al. (Research in Autism Spectrum Disorders 4(4):605–611, 2010). Younger toddlers produced higher rates of item failure than older toddlers and items in both of the later acquired item sets had higher probability rates for failure than the earliest acquired item set (prior to 8 months). Use of the same items and the same scoring throughout the target age range for autism screening may not be the best strategy for identifying the youngest toddlers at risk for autism.
