People are living longer and healthier than at any other time point in history. Therefore, in the last decade, international interest has focussed on the study of quality of life (QoL) in older people. Our aim was to study the psychometric properties of the generic QoL measure WHOQOL-BREF (WHOQOL, World Health Organization Quality of Life) and specific older adult module WHOQOL-OLD in a sample of 286 Spanish elderly.
Participants were 60 years and older from community centres, primary care centres, family associations and nursing homes. The following information was collected: demographics, self-perception of health, depressive symptoms (Geriatric Depression Scale, GDS-30), functional status (SF-12) and QoL (WHOQOL-BREF and WHOQOL-OLD). Analysis was performed using classic psychometric techniques with SPSS v15.0.
We found no ceiling and floor effects, and missing data was low. The internal consistency measured by Cronbach's alpha was 0.90 for the WHOQOL-BREF total scale and 0.80 for the WHOQOL-OLD. A priori expected associations were found between WHOQOL-BREF and WHOQOL-OLD with the SF-12 and the GDS-30, indicating good construct validity. WHOQOL-BREF and WHOQOL-OLD domain scores differentiated between participants with lower and higher level of education, and between groups of older people (healthy vs. unhealthy; non-depressed vs. depressed; non-carers vs. carers and non-residents vs. residents).
The WHOQOL-BREF and WHOQOL-OLD questionnaires demonstrate acceptable psychometric performance in a convenience sample of Spanish older people. They are valuable measures of QoL for use with older people.
人们的寿命和健康状况都达到了历史上的最佳水平。因此，在过去的十年中，国际社会对老年人生活质量（QoL）的研究产生了浓厚的兴趣。我们的目的是在一个由 286 名西班牙老年人组成的样本中研究通用生活质量量表 WHOQOL-BREF（WHOQOL，世界卫生组织生活质量）和特定老年模块 WHOQOL-OLD 的心理测量特性。
参与者来自社区中心、初级保健中心、家庭协会和养老院，年龄均在 60 岁及以上。收集的信息包括人口统计学资料、自我健康感知、抑郁症状（老年抑郁量表，GDS-30）、功能状态（SF-12）和生活质量（WHOQOL-BREF 和 WHOQOL-OLD）。使用 SPSS v15.0 进行经典心理测量技术分析。
我们没有发现天花板和地板效应，且数据缺失率较低。WHOQOL-BREF 总量表的内部一致性用 Cronbach's alpha 衡量为 0.90，WHOQOL-OLD 为 0.80。在 WHOQOL-BREF 和 WHOQOL-OLD 与 SF-12 和 GDS-30 之间发现了先验预期的关联，表明具有良好的结构效度。WHOQOL-BREF 和 WHOQOL-OLD 量表的各领域得分可区分出受教育程度较低和较高的参与者，以及老年人的不同群体（健康与不健康；无抑郁与抑郁；非照顾者与照顾者以及非居住者与居住者）。
在一个方便的西班牙老年人样本中，WHOQOL-BREF 和 WHOQOL-OLD 问卷表现出可接受的心理测量性能。它们是评估老年人生活质量的有价值的测量工具。
