This manual was developed for those interested in promoting change to improve health conditions of their communities. Parts I and II focus on fundamental health education processes and discuss techniques and approaches for working with community members to plan and develop programs that are responsive to the community's expressed needs and goals. Part III presents another aspect of educational programs, that of transmitting information about health topics. This section includes specific reference materials on selected health topics relevant to developing countries, and it also discusses methods and aids for presenting such information to individuals or groups. Part IV deals with four common community health problems: nutrition; maternal and child health; control of communicable diseases; and accidents--preventing and meeting emergencies. Six appendices are also included: (1) a discussion of how to construct a sample survey for the population; (2) examples of survey questions; (3) examples of six kinds of educational materials and aids; (4) a bibliography of sources of materials and information; (5) a vocabulary of words used in the manual; and (6) five preliminary guidelines regarding immunizations and health education.
