Interaction analyses added to the multilevel models of the randomized trial tested whether intervention effects varied by student characteristics; the article reports no significant interactions for any background or ability variable.

"No signi ficant interaction effects were determined for age, gender, SES, or ethnic/linguistic background. The intervention effects were also not dependent on the level of the student’s nonverbal intelligence, vocabulary, or decoding skills."
