The Infant/Toddler Program of the Louise Child Care Center began providing full time day care to young children of working parents in the fall of 1978. While delivering this service, the Center conducted a longitudinal, exploratory investigation into the responses of children and their families to a group-home day care setting. The study was conducted during the children's first eight months of attendance. The purpose of the first part of the study was to systematically observe, through video-documentation and subsequent behavioral analysis, the response of young children to daily separation from their parents. An additional focus of the study was to follow cognitive changes among participants. Use of the Bayley Scales of Infant Development allowed comparisons on developmental progress of the day care group against the Bayley standardized sample over time. This report is an overview of the program's findings on the 24 children in the project from October 1978 to June 1981. The first section of the report presents the purposes of the Infant/Toddler Program. The objectives of the research and their connection to other studies reported in the literature are discussed. Descriptions of the various components of the program follow, including an overview of the research design and methods of data collection and preparation. The remaining sections provide (1) a detailed examination and interpretation of the adjustment profiles of the children, (2) a summary statement of the findings, and (3) recommendations for further research. Related materials, including a discussion of stranger anxiety, videotaping protocols, and a case study are provided in eight appendices. (Author/RH)
