Abstract: Promoting quality of life in older age is an internationally recognized priority, requiring valid measurement. We present a short version of the established Older People''s Quality of Life questionnaire (OPQOL-brief). The full OPQOL-35 was original in being developed from the perspectives of older people, assessed conceptually, and validated with a population sample using gold-standard psychometric assessment. The OPQOL-brief was also developed by asking older people to prioritize the most important items from the OPQOL-35, next assessed psychometrically with a population sample, and also statistically against the discarded 22 items. The aim was to assess the psychometric properties of the short, 13-item version of the OPQOL (OPQOL-brief), and to compare the performance of included and discarded items. The method was a national population survey of people aged 65+ living at home. The measures were OPQOL-brief, WHOQOL-QOL and CASP-19. The OPQOL-brief was found to be a highly reliable and valid, short measure of quality of life in older age. The OPQOL-brief is of value in assessment of interventions where a rigorously tested, short measure is required. The grounded development of the instrument is consistent with international policy emphasis on user involvement in shaping policy and research. [Copyright &y& Elsevier]
