Client satisfaction can be used as an indicator for service quality. Without concrete feedback from clients, however, the usefulness of client satisfaction data for service improvement can be limited. This study described the development of a client satisfaction measure that can be used to provide concrete feedback for service providers. Based on a conceptual framework proposed in the literature, the Client Satisfaction: Home Care (CSAT-HC) uses a client-centered perspective to measure client satisfaction for homecare services for older adults. A survey of 200 older adults receiving homecare services provided by a social service agency in a large U.S. Midwest city was conducted to assess the psychometric properties of CSAT-HC. Results based on the 156 completed surveys show that CSAT-HC has good validity (correlation r = .62 with a popular client satisfaction measure) and test-retest reliability (r = .75). These results indicate that CSAT-HC is a valid and reliable client satisfaction measure; and therefore, providers of homecare services for older adults can use CSAT-HC to obtain client feedback for quality assurance or program evaluation purpose. Future research may use CSAT-HC to explore the potential influences of quality of homecare services on the well-being of older adult clients.
