Results of linear regression analyses predicting phonological awareness and print knowledge for the CI group.

Regression 1:
Phonological awareness
(R2 = .34)
 Regression 2:
Print knowledge
(R2 = .23)
Predictor β t p sr2 β t p sr2
Language composite .324 1.06 .301 .04 .243 0.74 .468 .02
Speech production .066 0.23 .820 <.01 .271 0.88 .390 .03
Speech perception .287 1.33 .197 .06 -.006 -0.03 .978 <.01

Note. For both regressions, all predictor variables were entered simultaneously in one step. sr2 is the squared semi-partial correlation coefficient, which represents the percentage of total variance in the criterion variable accounted for by each individual predictor variable with the other variables controlled.
