Predicting math outcomes: reading predictors and comorbidity

This commentary addresses issues concerning (a) the measurement of numbers, letters, and words versus cognitive processes in early screening batteries, and (b) comorbid associations of reading, math, and attention disorders. Based on reading prediction studies, assessments that include numbers should be most predictive of math outcomes. However, given the comorbid association of reading, math, and attention disorders, measures sensitive to reading and attention difficulties may be necessary in early screening batteries for math disabilities.
