Research studied the activities of four special units set up by four Federal agencies to handle the diffusion and utilization of their respective research products. Comparative functional profiles of each unit were first developed and revised to constitute a consensus self-portrait. Next, data on the research utilization networks of two of the units were obtained from questionnaires. Subsequently, two interface conferences were convened involving sub-samples of those surveyed in the network study. A theoretical model was then developed to describe a resource-user problem-solving dialogue within which it was possible to analyze all functions and activities of diffusion and utilization agencies. Communication network maps were drawn to depict the types and flow of information. Major findings were that: 1) research information was rarely sought in crises; 2) attitudes toward dissemination and utilization were dominated by ideologies termed "linkage", "user-centering,""Research Development" and "capacity"; and 3) the most important elements in the dissemination and utilization system which needed improvement were a) linkage, b) diagnosis of user needs, and c) planning and organization of the overall dissemination and utilization system.
