Thompson, James R.; Shaw, Leslie A.; Shogren, Karrie A.; Sigurðsson, Tryggvi; Stefándóttir, Guðny – American Journal on Intellectual and Developmental Disabilities, 2020
An innovation in developing the Supports Intensity Scale--Children's Version (SIS-C) was the adoption of latent variable modeling approaches to norm development. In regard to translated versions of the SIS-C, the latent modeling approaches provided opportunities to leverage the large standardization sample generated in the United States (n=4,015)…

Tomaszewski, Brianne; Hepburn, Susan; Blakeley-Smith, Audrey; Rogers, Sally J. – American Journal on Intellectual and Developmental Disabilities, 2020
Longitudinal growth modeling was utilized to examine adaptive behavior over eight years across the three time points (i.e., ages 2-10). Seventy-six parents completed the Vineland Adaptive Behavior Scales interviews of adaptive behavior. Child participants completed standardized developmental testing and an executive function task in toddlerhood…

Joyce, Anna; Hill, Catherine M.; Karmiloff-Smith, Annette; Dimitriou, Dagmara – American Journal on Intellectual and Developmental Disabilities, 2019
Sleep plays a key role in the consolidation of newly acquired information and skills into long term memory. Children with Down syndrome (DS) and Williams syndrome (WS) frequently experience sleep problems, abnormal sleep architecture, and difficulties with learning; thus, we predicted that children from these clinical populations would demonstrate…

Speech disorders occur commonly in individuals with Down syndrome (DS), although data regarding the auditory-perceptual speech features are limited. This descriptive study assessed 47 perceptual speech features during connected speech samples in 26 children with DS. The most severely affected speech features were: naturalness, imprecise…

Facon, Bruno; Magis, David – American Journal on Intellectual and Developmental Disabilities, 2019
Uncertainty persists regarding the post-childhood trajectory of syntactic acquisition of persons with Down syndrome (DS). In some studies, asymptote is reached in the early teens, whereas others find syntax continuing to develop at least into early adulthood. This study addressed the issue using a cross-sectional approach. Receptive syntax and…

Adams, Dawn; Clarke, Samantha; Griffith, Gemma; Howlin, Pat; Moss, Jo; Petty, Jane; Tunnicliffe, Penny; Oliver, Chris – American Journal on Intellectual and Developmental Disabilities, 2018
It is well documented that mothers of children with challenging behavior (CB) experience elevated levels of stress and that this persists over time, but less is known about the experience of mothers of children with rare genetic syndromes. This article describes 2 studies, 1 cross-sectional and 1 longitudinal, comparing well-being in mothers of…
