Do Children's Learning-Related Behaviors Moderate the Impacts of an Empirically-Validated Early Literacy Intervention?

The present study included 314 children who had been involved in Project STAR, and explored how two learning-related behaviors, interest in literacy and effortful control, moderated the impact of the literacy intervention on reading outcomes. Results indicated significant associations of both learning-related behaviors with reading, with the children with the highest literacy interest and effortful control in the intervention group showing the highest reading outcomes. These results indicate that accounting for a greater breadth of possible moderators of intervention impacts is an important area to explore.
