This operations research study sought to determine an effective and replicable communication-based model for increasing the involvement of community-based groups in improving access to and use of reproductive health services and information by young married couples, ages 24 and under. The study employed a quasi-experimental design with two experimental and two non-equivalent control groups in the Udaypur district of Nepal where the Nepal Red Cross Society (NRCS) had been implementing its Reaching and Enabling Women to Act on Reproductive Health Decision (REWARD) project with support from the United States Agency for International Development (USAID) and CEDPA. The two experimental models were the Youth Communication Action Group and the Mother’s Group. Researchers from the Center for Research on Environment, Health, and Population Activities (CREHPA) administered pre- and post-test surveys of young married women, ages 24 and under. The baseline survey, conducted in October 2000, covered a total sample of 1,000 respondents from the two experimental sites and 800 from the two control sites. The endline survey, conducted in October–November 2002, covered 744 respondents in the two experimental sites and 268 from one control site. A separate survey of 237 YCAG members was also conducted as a part of the endline study to assess the effectiveness of this model in enhancing the reproductive health knowledge and behavior of group members.
