This volume reports the baseline (1978) data to be used in the 6-year longitudinal evaluation of the Child and Family Resource Program (CFRP). The CFRP, funded in 11 sites across the country as a Head Start demonstration program, is intended to develop models for providing services to low-income families with children from birth to eight years. Chapter I provides an overview of the evaluation with an introduction to the three component studies: The Descriptive Program Study of all 11 CFRP sites, the In-Depth Study of families and staff in CFRP, and the Impact Study of program families and comparison groups (not in the program) at six of the sites. Chapter II presents descriptive data from the Program Study and explains how the programs differ, in some respects, from one site to another. Descriptive data from the Impact and In-Depth Studies, focusing on family participation, social service networks and family interaction, are presented in Chapter III. Chapter IV describes the data collection for the Impact and In-Depth Studies, including instruments and procedures, sample recruitment and staff recruitment and training. Appendices contain information on technical progress reports, characteristics of the 11 programs and sample recruitment. (Author/BH)
