Objectives: The purpose of this study was to identify determinants within the International Classification of Functioning, Disability and Health as a conceptual framework regarding the quality of life of older long-term care facility residents.Methods: A questionnaire-based cross-sectional design was conducted. All participants (n = 210) completed a questionnaire that included the Sheltered Care Environmental Scale, the Beck Depression Inventory, the Short Physical Performance Battery, the Mini-Mental State Examination, the World Health Organization Disability Assessment Schedule, and the World Health Organization Quality of Life Scale. The outcome was assessed using mixed-design multiple regression with a covariance model and hierarchical regression.Results: Personal factors, environmental factors, body function and structures, and activity and participation explained 35.9%, 18.5%, 25.2%, and 52.1% of the variability in quality of life, respectively. The hierarchical model included 10 variables and explained 84.3% of the total variability in quality of life.Conclusions: Activity and participation showed high explanatory power for the quality of life of older long-term care facility residents. The influence of activity and participation in the older population is an important issue, although these factors remain relatively unexplored. This exploratory study used the International Classification of Functioning, Disability and Health as a conceptual framework to provide a more sophisticated understanding of quality of life.Implications for rehabilitationAlthough the viewpoint of quality of life involves many more factors than an understanding of an individual disease or disability condition, activity and participation were found to be the most important factors.Simple clinical measures, such as activity limitations and participation restrictions, can be used as clinical markers of quality of life, thus enabling rehabilitation professionals to determine the quality of life of older people in institutions.The conceptual framework of determinants of quality of life that this study reports may be helpful for rehabilitation professionals to explore with patients to implement interventions.
