Primary care of adolescents. Issues in program development and implementation.

Recent reviews of adolescent primary care urge the development of a dynamic program evaluation strategy. An action research evaluation model that combines service, training, and research to foster the development and implementation of primary care services is presented. The strategy includes description of patient populations, determination of patient health care needs, specification of service objectives, assessment of health care resources, and evaluation of service procedures and outcomes. Elements of the action research strategy are applied to evaluate two current issues in adolescent primary care: family-oriented versus adolescent-limited services and "new morbidity".
