The effectiveness of the Pathways and Resources for Engagement and Participation (PREP) intervention: improving participation of adolescents with physical disabilities.

Environment-based intervention strategies, guided by the Pathways and Resources for Engagement and Participation, are effective in improving and maintaining adolescent participation. Intervention was most effective for males and those with a higher number of functional issues. The study design serves as an example for future pragmatic studies accounting for individual-based changes and contexts.
