Can a professional committee have any impact, even indirectly, on the well-being of children? The Child Development Committee of the Maternal and Child Health Section of the American Public Health Association (APHA) was established in October 1976 with the hope of responding to this challenging question. The Committee determined that one ideal index of accomplishment would be community support for quality day care and health services to preschool children and families. As the Committee identified barriers to delivery of these services, a clear priority emerged: the improvement of communication and cooperation between health care professionals and child care professionals. Among suggested strategies for increasing this inter-professional understanding, holding regional multidisciplinary workshops was chosen as the most appropriate strategy. The first section of this volume describes the process by which the Committee identified and brought together the various existing resource groups to plan, fund, and produce the workshop. The second section presents evaluative comments and findings of follow-up contacts with state-level and local community representatives, with particular reference to workshop-induced changes or potential changes in the health care/day care relationships. Tables from preliminary questionnaire data, as well as copies of evaluation forms used during the on-site evaluation and the follow-up evaluation are appended. (Author/MP)
