This manual offers guidelines for developing health and family planning support materials for illiterate and low-literate groups. The techniques used rely heavily on involvement of the target audience. Following the introduction, each of the nine sections of the guide discusses a separate step in the materials development process: (1) "target audiences" explains how to profile audiences and determine their specific needs; (2) "project planning" offers tips on formulating work plans to allocate time and financial resources; (3) "audience research" describes methods to derive information from the target audience to assess and understand its needs and concerns; (4) "message development" details the process of using data from focus group discussions and other audience research to develop messages and communicate them pictorially in a clear, sequential manner; (5) "guidelines for materials production" provides tips for preparing materials for low-literate groups; (6) "pretesting and revision" explains ways to ensure that the intended messages are conveyed and that the materials are acceptable to the target audience; (7) "printing" raises issues to consider during the production stage of the materials development process; (8) "distribution and training" describes how to disseminate the materials and train health workers to use them effectively with their clients; and (9) "evaluation" describes methods to examine the field use of the materials and their impact on the intended audience. The guide includes 18 references and lists 9 resources. Appendixes include pretest background sheets, data sheets, summary of results sheets, and a monthly record form for distribution of educational materials by health educators. (KC)
