Health education may be defined as a process that seeks to achieve voluntary changes in behavior conducive to health. Systematic program planning, based on an extensive investigation of the needs of a specific population is essential if health education is to attain validity in the eyes of the public, health professionals and policy makers who assess its value. In addition, unless educational programs have clearly defined and measurable objectives, health education will continue to be an area that uses the measurement of activities, rather than the measurement of changes in behavior and health status, as its ultimate goal. The PRECEDE model, presented here, offers a quantifiable means of conducting an educational diagnosis in health, behavioral and cognitive, attitudinal and organizational terms before the development of an educational program. The process allows the practitioner to define objectives, which form the basis for subsequent analyses of the effectiveness of the program.
