This report provides an overview of the development and evaluation of an experimental television series for adult viewers on health care. The series was produced by the Children's Television Workshop and aired in prime time during 1974-1975 by the Public Broadcasting Service. The report synthesizes results of complementary impact studies conducted by four independent research contractors: a study of voluntary viewing by Response Analysis Corporation; an induced viewing field experiment by National Opinion Research Center; four national surveys by Gallup Organization; and national audience estimates by A.C. Nielsen Company. Chapters one and two describe the development of the series, summative research plans and findings. Chapters three and four examine media strategy issues concerning public television and its audience, and findings of the behavioral outcomes related to 24 specific health topics covered in the series. Limitations of the evaluation process, implications of the research findings, and suggestions for studies are discussed in the last two chapters. A summary of this report appears as a separate ERIC document. (SC)
