The increasing proportion of older adults in the general population and the specific characteristics of this age group show the need for the development of specific instruments to measure quality of life in older adults. The study aimed at describing the development and validation of the Portuguese version of the World Health Organization Quality of Life for Older Persons (WHOQOL-OLD) module.
The WHOQOL-OLD instrument was administered in a sample of 424 older adults in the city of Porto Alegre, Southern Brazil, in 2005. The questionnaire comprises 24 items divided into six facets: sensory abilities; autonomy; past, present and future activities; social participation; death and dying; and intimacy. Besides the WHOQOL-OLD module, the WHOQOL-BREF, BDI and BHS instruments were also applied. The instrument's internal consistency was assessed using Cronbach's alpha coefficient.
The instrument showed adequate internal consistency (Cronbach's coefficients ranging from 0.71 to 0.88), discriminant validity (p<0.01), concurrent validity (correlation coefficients ranging from -0.61 to -0.50) and test-retest reliability (correlation coefficients ranging from 0.58 to 0.82). Findings concerning criterion validity need further studies.
The WHOQOL-OLD module is a useful alternative with good psychometric performance in the investigation of quality of life in older adults.
老年人群在总人口中的比例不断增加，且该年龄组具有特定特征，这表明需要开发专门用于测量老年人生活质量的工具。本研究旨在描述世界卫生组织老年人生活质量（WHOQOL-OLD）模块葡萄牙语版本的开发与验证过程。
2005年，在巴西南部阿雷格里港市的424名老年人样本中使用了WHOQOL-OLD工具。该问卷包含24个项目，分为六个方面：感官能力；自主性；过去、现在和未来的活动；社会参与；死亡与濒死；以及亲密关系。除了WHOQOL-OLD模块外，还应用了WHOQOL-BREF、BDI和BHS工具。使用克朗巴赫α系数评估该工具的内部一致性。
该工具显示出足够的内部一致性（克朗巴赫系数范围为0.71至0.88）、区分效度（p<0.01）、同时效度（相关系数范围为-0.61至-0.50）和重测信度（相关系数范围为0.58至0.82）。关于效标效度的研究结果需要进一步研究。
WHOQOL-OLD模块是一种有用的工具，在老年人生活质量调查中具有良好的心理测量性能。
