WRIT = Wide Range Intelligence Test; WRMT-R = Woodcock Reading Mastery Test- Revised; WJ = Woodcock Johnson; CREVT = Comprehensive Receptive and Expressive Vocabulary Test; NEPSY = A NEuroPSYchological Assessment; DKEFS = Delis Kaplan Executive Function System; RCFT = Rey Complex Figure Task; WMTB-C = Working Memory Test Battery for Children.
Standard score, population mean = 100 ± 15 (higher score = better performance).
Scaled score, population mean = 10 ± 3 (higher score = better performance).
T score, population mean = 50 ± 10 (higher score = better performance).
Only variables included in the final model are shown here with associated β statistics and corrected p-values. Variables excluded from final model are indicated with ‘---’. Note that final models are unique to each test, thus β values for a given variable cannot be quantitatively compared across tests.
