This study demonstrates the use of a social return on investment (SROI) approach in estimating the financial and social value created by volunteer-assisted community-based aging services. An expanded value added statement (EVAS) analysis found that the total value of outputs produced by the Concierge Club of San Diego substantially exceeded the cost of the program, after considering likely secondary and tertiary benefits for a range of affected stakeholders—including elderly service recipients, family members, volunteers, and societal institutions. Additional research is needed regarding the direct and indirect costs and benefits of volunteer support services for vulnerable older adults and their families. // (2015)
