By systematically examining the implementation of maternity group home programs in 22 different homes, this report fills some of the gaps in the existing literature. However, much remains to be learned about the operation and effectiveness of maternity group homes. For one thing, this study examined only 7 of the more than 100 maternity group home programs in the country. Moreover, this study focused on relatively large programs, most of which included a number of different affiliated homes. Future research would be necessary to determine to what extent, and in what ways, the many smaller programs and independent maternity group homes might differ from those included in this study. In addition, we cannot know to what extent maternity group home programs live up to their potential to address some important consequences of teen pregnancy without a rigorous evaluation of their effectiveness. Future research should include a careful examination of the impact of these programs on the well-being of the young mothers and children they serve.
