The World Health Organization’s WHOQOL-BREF quality of life assessment: Psychometric properties and results of the international ±eld trial A Report from the WHOQOL Group q S.M. Skevington 1 , M. Lotfy 2 & K.A. O’Connell 1 1 WHO Centre for the Study of Quality of Life, Department of Psychology, University of Bath, Bath, UK (E- mail: s.m.skevington@bath.ac.uk); 2 Department of Mental Health and Substance Dependence, World Health Organisation, Geneva, Switzerland Accepted in revised form 5 March 2003 Abstract Quality of life (QOL) assessments that are easily administered and which do not impose a great burden on the respondent are needed for use in large epidemiological surveys, clinical settings and clinical trials. Using data from the WHOQOL-BREF ±eld trials, the objectives of this work are to examine the performance of the WHOQOL-BREF as an integrated instrument, and to test its main psychometric properties. The WHOQOL-BREF is a 26-item version of the WHOQOL-100 assessment. Its psychometric properties were analysed using cross-sectional data obtained from a survey of adults carried out in 23 countries (n ¼ 11,830). Sick and well respondents were sampled from the general population, as well as from hos- pital, rehabilitation and primary care settings, serving patients with physical and mental disorders and with respect to quotas of important socio-demographic variables. The WHOQOL-BREF self-assessment was completed, together with socio-demographic and health status questions. Analyses of internal consistency, item–total correlations, discriminant validity and construct validity through con±rmatory factor analysis, indicate that the WHOQOL-BREF has good to excellent psychometric properties of reliability and per- forms well in preliminary tests of validity. These results indicate that overall, the WHOQOL-BREF is a sound, cross-culturally valid assessment of QOL, as reflected by its four domains: physical, psychological, social and environment. Key words: Assessment, Cross-cultural, Quality of life, WHOQOL-BREF Introduction Increasingly, health care planners are recognizing that measures of disease alone are insufficient de- terminants of health status. Over the past decades, two classes of complementary health status mea- sures have emerged to ±ll the information gap – objective measures of functional health status and subjective measures of health and well-being (for reviews see Refs. [1–4]). These measures are multi- level and multi-dimensional. There are many published quality of life (QOL) measures but there is still a lack of consensus among researchers about its de±nition and this is reflected in the choice of items for their instruments. The WHO de±nes QOL as ‘an individual’s per- ception of their position in life in the context of the culture and value systems in which they live, and in relation to their goals, expectations, standards and concerns’ [5]. In measuring QOL therefore, the WHOQOL Group takes the view that it is im- portant to know how satis±ed or bothered people
