On the Possibility of a Conceptual Model of Quality of Life

Abstract

Up to now, quality of life (QOL) research has been guided by several conceptual frameworks that allow for the generation of rather general approaches to QOL with very fragmented explanatory contributions, while no specific conceptual models can be identified in the literature. This paper, which is based on a critical review of mainstream literature, aims to highlight the main difficulties in building a conceptual model of QOL and to propose a model that can overcome some of the current issues. The difficulties in constructing such a conceptual model stem mainly from the variety of definitions and the range assigned to the concept of QOL, the consequent operationalisation of the concept, the relativity and multidimensionality of the concept and the subsequent problems with unidimensional measures. This paper proposes a conceptual model that adopts an individual perspective on the theoretical construct and introduces several novel ideas for building a comprehensive explanatory framework for QOL. The following developments and improvements are suggested with the purpose of clarifying the intricate field of QOL research and closing in on a conceptual model: honing in on essential dimensions instead of constantly expanding the concept, increasing the effort put into theorising about QOL, adopting a life course perspective, generating longitudinal data and utilising research on agency. There is a high need for the development of a conceptual model of QOL and the concurrent integration of QOL approaches, at least at the European level, as this would contribute to fostering the advancement of the QOL research field and highlighting core European values regarding QOL standards.
