A best evidence synthesis of literacy instruction on the social adjustment of students with or at-risk for behavior disorders

The findings of a best-evidence synthesis of the collateral effect of literacy instruction on the social adjustment of students are reported. The goal of the synthesis was to extend the work of Wanzek, Vaughn, Kim, and Cavanaugh (2006) by (a) reviewing treatment-outcomes conducted using group design methodology; (b) focusing on a more defined set of outcome measures; and (c) analyzing outcomes using average effect size estimates as a common metric. Results of the review suggest that effective literacy instruction does not appear to have a collateral effect on the social adjustment of children. Limitations and future directions are presented.
