Utilizing volunteer research assistants in epidemiologic studies.

Utilizing volunteers in research-assistant roles can provide a new model for extending research dollars in epidemiologic studies of the elderly. This is increasingly important with a rapidly growing older population suffering from an increasing prevalence of disability, disease, and the related medical costs. During a two-year cross-sectional study of factors that predict health aging conducted by the Buck Center for Research in Aging in Marin County, California, 82 volunteers were recruited and trained to fill roles often held by paid research assistants. The key activities of telephone screening, interviewing, coding, and data entry were successfully completed by trained volunteers following standards and within a time frame comparable to similar studies. Volunteer research assistants contributed approximately 13,600 hours that resulted in a savings in personnel costs of over $100,000. Many of the people recruited and trained as volunteer research assistants were healthy older adults and retired workers. The project utilized their transferable skills and talents in an interesting and productive capacity.
