This final report describes the activities and accomplishments of a 3-year model demonstration early intervention network serving infants who are deaf-blind and their families. The primary goal of the project was to build the capacity of early intervention programs. Sixteen early intervention programs participated in at least one component of the project and nine programs participated in a majority of project activities. Project activities involved identifying, developing, and documenting effective early intervention practices with infants whose multiple disabilities include both vision and hearing loss and their families. Project objectives were accomplished through such activities as: family/professional focus group meetings, program self-reviews, program development plans, interdisciplinary focus group meetings, a supervisory focus group meeting, workshops, follow-up consultation, and materials development. The project produced a manual on effective practices in early intervention with this population and four videotapes which have been made commercially available: "Making the Most of Early Communication,""What Can Baby Hear? Auditory Tests and Interventions for Infants with Multiple Disabilities,""What Can Baby See? Vision Tests and Interventions for Infants with Multiple Disabilities," and "Vision Tests for Infants." Individual sections of the report cover the project s goals and objectives, conceptual framework, model and participants, activities, problems and departures from the original plan, evaluation findings, and impact.
