Clinical preventive services for adolescents.

Context: Most of the many clinical preventive services (CPS) recommended for adolescents by various national organizations lack good evidence of effectiveness.

The objective of the current study was to identify those CPS for adolescents that do have a strong evidence base, to update the literature review and summarize evidence gaps where research is needed, and to summarize current delivery prevalence and opportunities.
