A Review and Analysis of Single-Case Research Examining Adolescent Participation in IEP Meetings

The purpose of this systematic review and meta-analysis was to identify and synthesize single-case research examining interventions used to increase the quantity and/or quality of participation by adolescents with disabilities during Individualized Education Program (IEP) meetings. For studies meeting quality indicators, we used visual analysis, Tau-U, and standardized mean difference to synthesize outcomes, including maintenance and generalization of effects. We identified seven studies examining quality of participation and eight studies examining quantity of participation that met our inclusion criteria; however, only three studies from each group met quality standards. Overall, interventions positively influenced student contributions at IEP meetings. When measured, increased quantity and quality of participation maintained over time and generalized to real IEP meetings. Implications for research and practice are discussed.
