Peer reviewed Peer reviewed
Direct linkDirect link
Spencer, Mercedes; Wagner, Richard K.; Petscher, Yaacov – Journal of Educational Psychology, 2019
The present study examined the reading comprehension and receptive vocabulary skills of children with poor reading comprehension despite adequate decoding using a regression-based matching technique. Participants included five cohorts of children who were identified as typical readers (N = 70,493 - 75,553) or as children with specific reading…

Quinn, Jamie M.; Wagner, Richard K.; Petscher, Yaacov; Roberts, Greg; Menzel, Andrew J.; Schatschneider, Christopher – Journal of Educational Psychology, 2020
In this large-scale study of students from Title 1 schools (N = 14,773), we used multiple-group latent change score (LCS) modeling to investigate the developmental relations between vocabulary knowledge and reading comprehension in students with a school-identified learning disability (LD; n = 627) and typically developing students (n = 14,146).…

Quinn, Jamie M.; Wagner, Richard K.; Petscher, Yaacov; Lopez, Danielle – Child Development, 2015
The present study followed a sample of first-grade (N = 316, M[subscript age] = 7.05 at first test) through fourth-grade students to evaluate dynamic developmental relations between vocabulary knowledge and reading comprehension. Using latent change score modeling, competing models were fit to the repeated measurements of vocabulary knowledge and…

Spencer, Mercedes; Muse, Andrea; Wagner, Richard K.; Foorman, Barbara; Petscher, Yaacov; Schatschneider, Christopher; Tighe, Elizabeth L.; Bishop, M. Denise – Reading and Writing: An Interdisciplinary Journal, 2015
We report results from two studies on the underlying dimensions of morphological awareness and vocabulary knowledge in elementary-aged children. In Study 1, 99 fourth-grade students were given multiple measures of morphological awareness and vocabulary. A single factor accounted for individual differences in all morphology and vocabulary…

Modeling the Co-Development of Correlated Processes with Longitudinal and Cross-Construct Effects
Peer reviewed Peer reviewed

Petscher, Yaacov; Quinn, Jamie M.; Wagner, Richard K. – Developmental Psychology, 2016
Conceptualizations of developmental trends are driven by the particular method used to analyze the period of change of interest. Various techniques exist to analyze developmental data, including individual growth curve analysis in observed and latent frameworks, cross-lagged regression to assess interrelations among variables, and multilevel…

Incorporating RTI in a Hybrid Model of Reading Disability
Peer reviewed Peer reviewed
Direct linkDirect link
Spencer, Mercedes; Wagner, Richard K.; Schatschneider, Christopher; Quinn, Jamie M.; Lopez, Danielle; Petscher, Yaacov – Learning Disability Quarterly, 2014
The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…
