An Integrated Conceptual Model of Quality of Life for Older Adults Based on a Synthesis of the Literature

Abstract

Quality of life is fast becoming a standard of measure of long-term care and gerontological service outcomes. Although the issue of quality of life has been of increasing interest in the field of aging, there has been little agreement as to the clarity and definition of the concept and how to measure it, especially as it relates to older adults. Presented here is a comprehensive, integrated model of quality of life that was developed by synthesizing existing constructs within the literature into six major life domains—(1) social well-being, (2) physical well-being, (3) psychological well-being, (4) cognitive well-being, (5) spiritual well-being, and (6) environmental well-being. Consistent with a general systems framework, this holistic model expands the predominant Health-Related Quality of Life constructs to incorporate non-physical aspects of well-being. Each of these domains was broken down into several dimensions in an effort to operationalize the concept of quality of life so that it can have some common standard of useful measurement. These major life domains and indicators are important factors in determining the perceptions of quality of life of older adults. Understanding what constitutes quality of life and how to measure it comprehensively has significant implications for social policy and practice in the field of aging.
