Predicting 18-month M-CHAT-R/F with PediaTracTMv3.0 motor and social/communication/cognition domains
… using cross-sectional (9- and 12-month) and longitudinal (0–12-month) latent traits of motor (MOT) and social/communication/cognitive (SCG) abilities. Results. Strong convergent validity was found between PediaTrac and ASQ-3 domains at both time points. MOT at 9-months was the strongest …

Latent class modelling of respiratory outcomes in a South African birth cohort
… for identifying latent structures and modelling longitudinal trajectories, tracking 1143 children until school age. To identify wheezing phenotypes, partition around medoids (PAM) clustering tailored for longitudinal data, latent class analysis (LCA) and LCA with random effects were applied and …

Negative Affect Longitudinally Predicts Anxiety, Not Autism, In Young Children With Fragile X Syndrome
… risk for anxiety disorders, yet few studies have longitudinally investigated FXS as a high risk sample for teasing apart the early manifestations of debilitating anxiety symptoms. Due to the high comorbidity and overlapping phenotypic features of autism and anxiety within FXS, investigating …

Longitudinal relationships between family routines and biological profiles in youth with asthma
… level. The current study investigated whether longitudinal trajectories of inflammatory markers of asthma could be predicted by levels of family routines in youth with asthma. Family routines were assessed at baseline through parent questionnaires and peripheral blood samples obtained from …

Using learning analytics to evaluate design changes in MOOCs : a case study on assessing course pacing
… The most striking difference was seen in the longitudinal trajectories, with instructor-paced students mostly taking the same trajectory and self-paced students pursuing their own individually paced trajectories. We showed that these trajectories are correlated with student grade, and students …

Neural correlates of executive functioning in preschool children
… who previously participated in the PediaTracTM longitudinal study were recruited for the current study, in which they completed behavioral measures of EF ability (n = 37) and resting-state EEG data collection (n = 34). Age-related decreases in theta power were found but expected increases in …
