The World Health Organization has developed a brief generic questionnaire to assess quality of life, the WHOQOL-BREF. It has been studied in diverse groups, but not specifically in older people. The purpose of this study was to analyze the psychometric properties of the French version of the WHOQOL-BREF questionnaire in healthy older people and to compare the mean profiles of participants with the mean profile obtained in the international validation study of the WHOQOL-BREF. Of the total sample of 262 Swiss French speaking older participants, 122 completed a retest after 2 weeks. The WHOQOL-BREF items demonstrated high test-retest reliability and validity. The WHOQOL-BREF items were differentially related to physical and mental health measures (SF-12 components, morbidity, and depression), thereby demonstrating convergent and discriminant validity. Compared to the international validation sample of the WHOQOL-BREF, participants of the present study reported higher QOL on 22 of the 26 items. A comparison of item profiles between male and female participants revealed gender differences for two items only (social support and negative feelings). We conclude that the psychometric properties of the WHOQOL-BREF items in older adults are good. To consider the 24 specific facets that are assessed by the WHOQOL-BREF appropriately, we recommend using item profiles on the individual and the sample level.
世界卫生组织制定了一份简短的通用问卷来评估生活质量，即世界卫生组织生活质量简表（WHOQOL-BREF）。该问卷已在不同群体中进行了研究，但未专门针对老年人。本研究的目的是分析法语版WHOQOL-BREF问卷在健康老年人中的心理测量特性，并将参与者的平均概况与WHOQOL-BREF国际验证研究中获得的平均概况进行比较。在262名瑞士法语区老年参与者的总样本中，122人在2周后完成了重测。WHOQOL-BREF各项显示出较高的重测信度和效度。WHOQOL-BREF各项与身心健康指标（SF-12分量表、发病率和抑郁）存在差异相关，从而证明了收敛效度和区分效度。与WHOQOL-BREF的国际验证样本相比，本研究的参与者在26项中的22项上报告了更高的生活质量。男性和女性参与者之间的项目概况比较仅显示出两项存在性别差异（社会支持和负面情绪）。我们得出结论，WHOQOL-BREF各项在老年人中的心理测量特性良好。为了恰当地考虑WHOQOL-BREF评估的24个具体方面，我们建议在个体和样本层面使用项目概况。
