The Danfa Comprehensive Rural Health and Family Planning Project was a joint effort of the Ghana Medical School, the Ministry of Health, UCLA, and USAID. A health education component was developed as an integral part of program inputs during the initial conceptual phase of the project. As a result non-equivalent experimental and control areas were designated permitting an assessment of program impact during a five-year period (1972-1977) for which baseline and follow-up study data were available. A new cadre of community-based workers (Health Education Assistants) was developed from existing health personnel in the country, and trained in health education and multipurpose health work. Although the HEAs were found to have difficulty in bringing about changes in health practices when other support services were not available, they did have measurable impact on villagers' adoption of family planning methods and a number of specific health practices.
