This final report describes the activities and accomplishments of a 3-year project in New York City on the formation and maintenance of social relationships and social networks of children and adolescents with deaf-blindness. Research activities attempted to: (1) identify patterns of social interaction and social networks across educational environments which had varying degrees of integration or inclusive programs; (2) monitor the development of social relationships across natural environments; (3) document effective interventions and supports which promoted social exchange between students with deaf-blindness and their peers; and (4) increase social opportunities within the schools and communities for children and adolescents with deaf-blindness and their families. Project activities focused on increasing awareness about the social and communication skills of students with deaf-blindness and promoting opportunities for social interaction at school, at home, and in the community. The project provided direct services to 10 students with deaf-blindness, their peers, families, and educators. The report describes the project's theoretical and conceptual framework, methods and procedures, interventions, general results, and dissemination. An appendix summarizes classroom techniques for working with these students. (Contains a bibliography of about 100 references.) (DB)
