Note. Table displays the mean change score (i.e., post-test score minus pre-test score) for each group and outcome measure, with the pre-test score for that measure co-varied out. For standardized language tests, both standard and raw score changes are listed. The control group was omitted from the ROW-S and EOW-S analyses due to small group size for those variables. P values indicate the significance of the ANCOVA analysis comparing the four groups’ change scores. See Table 1 Note for descriptions of variables and a list of abbreviations.
