Research focused on children and youth.

We reviewed 22 articles on children and youth published in 2011 in the American Journal of Occupational Therapy and organized the articles by level of research and research type according to a framework adapted from the International Classification of Functioning, Disability and Health (ICF; World Health Organization, 2007). The largest percentage of articles described intervention effectiveness studies classified as Level III or IV. The bulk focused on the Body Function/Body Structure construct of the ICF, but as a whole the studies addressed all the constructs except Biomedical Molecular/Cellular. Rigor remains a concern, although laudable efforts have been made to increase strength of the evidence. Longitudinal, efficacy, and qualitative studies, as well as studies examining adolescents and the transition to adulthood, were absent from articles in this review and are important areas for future investigation. Several studies explicitly addressed intervention fidelity, an imperative in evidence-based research needed to move the profession toward the Centennial Vision.
