Quality of Well-Being Scale
Erik J. Groessl & Robert M. Kaplan
The Quality of Well-Being Scale (QWB) is a generic, preference-based measure of health-related quality of life (HRQOL). It has been extensively validated, and its psychometric properties are well established. A self-administered version of the QWB (QWB-SA) has been developed and validated in response to limitations of the QWB, and it is easier to administer in most research and clinical assessment protocols. The questionnaire assesses the presence or absence of symptoms and functioning on specific days prior to administration. The measure produces a single score that ranges from 0 (death) to 1.0 (optimal HRQOL). The score can be integrated with time and mortality to calculate quality-adjusted life years (QALYs) and conduct cost-effectiveness analysis. To place each case on the continuum between death and optimum functioning, the measure uses mean preference weights from a community sample. QWB scores are most commonly used to describe the HRQOL of larger groups or samples and ...
