Methods of Measuring Quality of Life: Theoretical Aspects and Empirical Evidence from Older Persons at Rajshahi City in Bangladesh

Bangladesh has become an ageing society and is going to increase her older persons. Health condition, quality of life (QOL) and physical functioning are worsen as people age. Due to increasing life expectancies, enhancement of medical and health facilities, modernization, Bangladesh, recently, experiencing the rapid change in demographic transition, as well as the most common challenge, population ageing. This paper presents an organizing framework that assists researchers in the design and validation of formative and reflective measurement models for assessing QOL of older persons. The framework draws from the extant literature, includes both theoretical and empirical considerations, and is illustrated through empirical example for measuring QOL of older persons using data from a project entitled “Quality of Life and Active Ageing of Older persons at Rajshahi City in Bangladesh” conducted at the Department of Population Science and Human Resource Development, University of Rajshahi. This example concern constructs that is fundamental to theory-building in this discipline, and most of the scholars used formative model. In contrast, application of the framework to this example suggests that a reflective measurement model may be more appropriate. These results reinforce the need to justify, both theoretically and empirically, the choice of measurement model for measuring subjective QOL.
