Treiman, Rebecca; Hulslander, Jacqueline; Olson, Richard K.; Willcutt, Erik G.; Byrne, Brian; Kessler, Brett – Scientific Studies of Reading, 2019
We examined the predictive value of early spelling for later reading performance by analyzing data from 970 U.S. children whose spelling was assessed in the summer following the completion of kindergarten (M age = 6 years; 3 months). The word reading performance of most of the children was then tested after the completion of Grade 1 (age 7;5),…

Hajovsky, Daniel B.; Reynolds, Matthew R. – Canadian Journal of School Psychology, 2019
To better understand the longitudinal relations between risk and relationship variables during early to middle adolescence, we employed latent variable cross-lagged panel models using data (N = 1,050) from the National Institute of Child Health and Human Development Study. Results showed self-reported individual risk behavior ([beta] = 0.77-0.88)…

Cirino, Paul T.; Tolar, Tammy D.; Fuchs, Lynn S. – Journal of Educational Research, 2019
Algebra I is a crucial course for middle and high school students for successful STEM-related coursework. A key issue is whether students should take Algebra I in Grade 8 versus Grade 9. Large-scale policy studies show conflicting results, and there are few (particularly longitudinal) individual difference studies. In the study, 53 students were…

Estrada, Eduardo; Ferrer, Emilio; Shaywitz, Bennett A.; Holahan, John M.; Shaywitz, Sally E. – Developmental Psychology, 2018
Identifying change at the individual level is an important goal for researchers, educators, and clinicians. We present a set of statistical procedures for identifying individuals who depart from a normative change. Using Latent Change Scores models (LCS), we illustrate how the Individual Likelihood computed from a statistical model for change…
