This final report presents an overview and description of a federally-funded model demonstration project that focused on the delivery of comprehensive services to developmentally delayed infants in rural areas. Efforts during the first year of the project (FY 1982) focused on the development of processes and procedures for establishing community linkages and the model of child intervention. Emphasis during the second year (FY 1983) reflected the refinement of the linkage process and initiation of the direct service component. Documentation of the processes and procedures implemented and expansion of established linkages occurred during the third year (FY 1984). This volume presents an overview of the conceptual model and detailed descriptions of its implementation components. The following sections are included: Introduction; Community and Linkage Development; Formal Structured Interaction; Direct Services to Children/Families; Monitoring and Maintenance; Staffing Consideration; and Summary. Appended are Personnel Vitae. (Contains 32 references, 41 figures, and 9 tables.) (SG)
