The factor structure of the CORE Phonics Survey was analyzed using a sample of 165 students in upper elementary school with specific learning disabilities. Confirmatory factor analysis was used to identify the hypothesized constructs of the CORE Phonics Survey and predictive validity of the CORE Phonics Survey to predict students' success in word…

We investigated the latent factor structure of the "Phonological Awareness Literacy Screening for Kindergarteners" in Spanish ("PALS español K"). Participants included 590 Spanish-speaking, public-school kindergarteners from five states. Three theoretically-guided factor structures were measured and tested with one half of our…

The genetic factor structure of a range of learning measures was explored in twin children, recruited in preschool and followed to Grade 2 ("N"?=?2,084). Measures of orthographic learning and word reading were included in the analyses to determine how these patterned with the learning processes. An exploratory factor analysis of the…
