This report documents research conducted under the Women's Studies Project (WSP) from 9/93 to 3/98 on the impact of family planning (FP) on women's health and quality of life. Individual chapters discuss: WSP research methodologies; cross-cutting themes that emerged from the research and implications for reproductive health policies and programs; the conceptual framework guiding the research; lessons learned; and directions for future research. A lengthy chapter summarizes, by region and country, the findings of more than 30 research projects conducted worldwide under the WSP. Each study is briefly described, along with key results, in the appendices. WSP research topics reflect the diversity of women's concerns and include, among others: strategies to counter family and community opposition to contraceptive use (Mali); generational differences in FP experiences (China); the impact of men's views on women's contraceptive behavior (Bolivia); the impact of FP on women's domestic lives (Indonesia), on women's self-esteem and self-image (the Republic of Korea), and on women's participation in the work force (the Philippines); the impact of tubal ligation on quality of life (Brazil); the social and behavioral consequences of unintended pregnancy (Egypt); the effects of gender on adolescent views of sexuality (Jamaica); and FP and women's participation in the development process (Zimbabwe). Research was guided by a conceptual framework that incorporated the complex and multidimensional aspects of women's lives, the possible impact of strong external factors such as gender norms and sociopolitical climates, and the overall context of women's reproductive health needs. Lessons for future research include the following: (1) The research agenda should be defined locally, with input from the "triangle" of researchers, policymakers/providers, and women's advocates. (2) Women's advocates should be involved throughout the research process to ensure that research incorporates women's voices and reflects their concerns. (3) Multiple research methods provide a fuller understanding of women's perspectives. (4) Social science studies must devote explicit attention to protecting study participants' confidentiality and informed consent. (5) Information dissemination should be part of the research plan and budget, not an afterthought. (6) Disseminating research findings to study participants enhances the latter's prospects of benefitting from their experience. Includes recommendations for changes in health policies and programs.
