This report describes Project OASIS (Older Adults Sharing Important Skills), a project designed to provide paraprofessional mental health services to nursing home residents by providing training for older adult volunteers in areas related to mental health and the elderly, supervision by OASIS staff, and consultation by staff. The background of the project is described and the advantages of using older adult volunteers to provide services to elderly nursing home residents are discussed. The development of Project OASIS as a pilot program is explained and training and development issues are explored. Profiles are included of the typical nursing home resident and of the average OASIS volunteer. Three nursing home resident-OASIS volunteer teams are described in brief case studies. The evaluation of the OASIS project is discussed; evaluation methods are described; and findings from volunteer, staff, and client interviews are presented. The report concludes that the OASIS project has been able to provide a diverse range of services to nursing home residents and has provided a meaningful and productive outlet for the volunteers interested in working with these residents. It is emphasized that the OASIS project can be replicated in communities of all sizes. (NB)
