Disparities in school, work, and community participation impact the 15% of youth in the United States estimated to have a developmental disability. A growing body of literature suggests disparities in participation are due to barriers in the physical and social environment. Practitioners and advocates have developed skill and advocacy interventions in an attempt to increase the participation of youth with disabilities. Yet none of these interventions focus specifically on acquiring the problem-solving skills needed to identify environmental barriers and generate modification strategies to resolve barriers to participation. Research indicates that there is a vital need to develop manualized, theory-based interventions that empower youth with developmental disabilities to identify and advocate for environments that support their participation in school, work, and the community.
