Note: GR = good readers; PR = poor readers. Model 1 = rapid serial naming (RSN), phonological processing (PP), and orthographic processing (OP) as concurrent predictors of the performance on oral reading fluency (ORF)mediated by word reading accuracy (WA). Model 2: rapid serial naming (RSN), orthographic processing (OP), and phonological processing (PP) as concurrent predictors of the performance on oral reading fluency (ORF) mediated by pseudoword reading accuracy (PWA). CFI = Comparative Fit Index; RMSEA = Root Mean Square Error of Approximation and the confidence interval of 90%; TLI = Tucker-Lewis Index.
