Capturing attitudes towards research and data sharing in down syndrome (CARDS-DS)
Open science initiatives aim to accelerate research through data sharing. While prior research has explored public attitudes toward genomic data sharing, perspectives on sharing other data types, such as neuroimaging data, remain largely unexplored. To address this gap, we developed the CARDS-DS (Capturing Attitudes toward Research and Data Sharing in Down Syndrome) questionnaire, a novel survey designed to assess parental attitudes toward open-a…
Infant vocalizing and phenotypic outcomes in autism
Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR…
Examining the factor structure and discriminative utility of the Infant Behavior Questionnaire–Revised in infant siblings of autistic children
Using the Infant Behavior Questionnaire–Revised in a longitudinal sample of infant siblings of autistic children (HR; n = 427, 171 female, 83.4% White) and a comparison group of low-risk controls (LR, n = 200, 86 female, 81.5% White), collected between 2007 and 2017, this study identified an invariant factor structure of temperament traits across groups at 6 and 12 months. Second, after partitioning the groups by familial risk and diagnostic outc…
Diagnostic shifts in autism spectrum disorder can be linked to the fuzzy nature of the diagnostic boundary
BACKGROUND: Diagnostic shifts at early ages may provide invaluable insights into the nature of separation between autism spectrum disorder (ASD) and typical development. Recent conceptualizations of ASD suggest the condition is only fuzzily separated from non-ASD, with intermediate cases between the two. These intermediate cases may shift along a transition region over time, leading to apparent instability of diagnosis. METHODS: We used a cohort …
