Save Favorite

These data are for each item on all achievement and behavioral assessments completed during the original intervention projects. The dataset is wide, with separate variable names for each wave of assessment. All participants (n= 4,038) are included. These data can be linked to the "total level" data using the PK_ID variable.

These data represent a combined dataset of Drs. Stephanie Al Otaiba and Carol Connor's RCT projects. Therefore, these data are not unique, in that the original investigators may have shared the individual datasets in other places that we are not aware of.
