Measuring well-being in minority groups is complex and challenging. Scales are available that have been validated in specific parts of the population such as older people. However validation among combinations of minority groups such as older adults of ethnic minority backgrounds is lacking. Findings We pooled data from two surveys of older adults in Great Britain one conducted among White British people and one among four ethnic minority groups. Quality of life was measured by the Older People s Quality of Life OPQOL Control Autonomy Self-realisation Pleasure CASP-19 and World Health Organization Quality of Life scale for older people WHOQOL-OLD . We found differences some significant between groups in terms of selfreported importance of various aspects of quality of life. A regression model of each total quality of life scale revealed greater unexplained variability in the White British group than the others. Principal components analysis within each ethnic group s data showed considerable differences in the correlation structures. Conclusions There are differences between ethnic groups that are consistent across the three scales and are not explained by a battery of predictor variables. If scales such as these are used to compare quality of life between ethnic groups or equivalently between geographical regions the different results in each group are liable to bias any comparison which .
