Latent social communication cognition growth trajectories of term and preterm infants/toddlers based on caregiver report.

ABSTRACT:

Background

Analysis of developmental trajectories is crucial to understand how and when neurodevelopmental vulnerability contributes to social, communication, and cognitive impairments. We report on an online, longitudinal caregiver-report tool that characterizes the growth trajectories of social communication cognition (SCG) abilities in infants/toddlers born term or preterm.

Methods

Longitudinal item response theory modeling was used to estimate item parameters of caregiver ratings on the SCG domain of PediaTrac^TM in a sample of 571 neonates (331 term, 240 preterm) from the newborn period to 18 months. Moderating effects of sex was examined. It was hypothesized: 1) trajectories of the latent trait SCG could be estimated by gamma1 (slope) with alpha discriminatio
