Focusing on the effects that research on the Taiwan family planning program has had on social change, both in the intergration of research findings into national action programs and in the dissemination of these ideas to other Asian countries, this report discusses five individual case studies and presents a summary and analysis of the research data. The first case illustrates how an action-oriented research program served as a base for the national expansion of an individual program and describes the organizational setup and approaches that expedited research utilization. A communication-oriented study with clear objectives, stressed in the second case, demonstrates the value of a single agency, the importance of feedback, the value of building on previous research, and the benefits of communication among research and staff members. The third case describes a nonfertility incentive plan, its regional implications, and the role of foreign aid in implementing the plan. The final two cases illustrate, respectively, reasons why contraceptive research findings are not applied and the value of giving close attention to feedback from field workers and consumers of the service.
