The Nature of Quality of Life: A Conceptual Model to Inform Assessment

Abstract
The phenomenon of quality of life (QoL) has been subject to ongoing debate and many models have been proposed. Over the latter half of the 20th century, QoL models have proliferated, particularly in relation to the population with intellectual disabilities (ID) which have arguably improved living conditions and helped to guard against abuse. While this is a complex phenomenon, there is agreement across a wide literature that QoL has two distinct aspects relating to the individual (whether disabled or not) and the resources necessary for a “good” QoL. Considerable support is also provided for a number of diverse but robust domains. However, how the “nature” of QoL is conceptualized is unclear. The article reviews multidisciplinary research on QoL and goes on to present a theoretical model of the nature of QoL that encompasses identified domains. The model is based on Maslow's hierarchy of needs (1987) which defines its scope; Sen's Capability Approach (1985), which elaborates the resource context impacting QoL; and Ryan and Deci's Self‐Determination Theory (2000), which describes person‐context interactions important to personally valued QoL. This conceptualization was framed within four facets—Foundational well‐being; Psychosocial well‐being; Status; and Autonomy—each of which have two aspects: “individual,” describing personal needs that, when fulfilled, are associated with better QoL, and “context,” describing resources necessary to enab...
