隨著人口老化速度加快，政府陸續開辦各種長期照顧以降低家屬照顧負荷，增進長者生活品質，有關照顧服務品質與責信議題亦日趨受到重視。老人日開照顧服務是改善其生活品質的重要措施，但是目前在學理與量化研究上仍相對不足，為此，本文主要目的在於分析日開照顧中心老人生活品質及其影響因素。在檢閱日間照顧及生活品質文獻後，本文以集群抽樣方式針對「南投縣老人日間照顧中心實施方案」參與者進行訪問調查，並獲得226份樣本資料。經探討群體意識、服務滿意度及生活品質等變項之因素結構後，本研究建立變項間之結構方程模式，研究結果顯示年齡、服務滿意度及群體意識影響長者之生活品質，其中更以群體意識為最重要解釋變項。研究結果在學理及實務面的意涵並於文後深入討論。

With the population of older adults growing steadily, numerous long term care had been proposed by government to reduce family burden and improve the quality of life (QoL) of the aged. Issues of quality and accountability in care services for older people are of increasing importance. Elderly day services is one means to improve QoL, however, theoretical and quantitative discussion about this topic are rare. For this reason, this study aims to investigate QoL and its affecting factors. Through a review of the literature on day services and QoL, 226 older people who participate in Nantou County Elderly Day Service Center Project were selected by cluster sampling method. With examining the factor structure of sense of community (SoC), service satisfaction, and QoL, this study developed structural equation models among variables. Results indicate that age, services satisfaction, and SoC are potential effectives on QoL. In addition, SoC is the most important affecting factor. Finally, implications for academic and practice were discussed.
