本研究欲瞭解失能老人各項資源、居住安排的決定掌控力、居住安排與生活品質之間的關係。以結構式問卷實地訪談住在社區家裡和機構裡的失能老人共計324位。結果符合理論架構與假設，亦即老人的資源、決定掌控力、居住安排均與生活品質有顯著的關係。複迴歸分析也證實大部分變項能預測老人的生活品質。 The purpose of this study is to examine the effect of various resources, living arrangement, and locus of control of living arrangement on quality of life in disabled older persons. Survey research with face to face interview was employed. Feelings and experiences of 324 disabled older persons using structured questionnaires were collected. The findings indicated that some personal resources in terms of sociodemographic characteristics and health resources, economic resources, family resources as well as social resources do have influences on quality of life. In addition to resources, locus of control on living arrangement and living arrangement also has their effects. More to the point, the older persons who are younger, are healthier, have more income, spend less care expense, have more interactions with adult children, use fewer formal resources, live in community, have larger locus of control, have higher quality of life. The finding supports the predictions generated from our research framework. Finally, practice and policy implications are discussed.
