This briefing report on program evaluation notes that the new wave of family-centered, integrated services is forcing the field to rethink its methodology, and that the move towards outcome-driven reforms requires carefully defined outcomes and ways to measure them. Highlights of a seminar meeting held to explore these issues are included. The background briefing report itself begins with an introduction that stresses the need to reform patterns of delivering services to children and families. It asserts that creative approaches to evaluation must be developed and tested, and that improved and integrated data systems must be an integral part of improving service delivery. This report presents a broad framework for understanding the challenges involved with this reform. Its purpose is to share some preliminary thinking about what issues are, and about the kinds of data systems and evaluation studies needed to implement and assess new initiatives. Part I centers on program evaluation and the search for a new paradigm. It describes different evaluation approaches (microsimulation, experimentation and quasi-experimentation, qualitative evaluation) and their relevance to the new paradigm, and considers the additional approach of case studies. Part II discusses outcomes definition and measurement. Part III looks at information systems and data integration. Part IV considers the role of the federal government in data integration and evaluation. Part V presents examples of current research, data integration, and evaluation initiatives. Lists of guides and references are included. (NB)
