背景：WHOQOL-OLD是一种评估老年人主观生活质量的工具。它以世卫组织对生活质量的定义为基础，有20多种语言版本。然而，在大多数国家，WHOQOL-OLD的心理测量特性仅在小的当地样本的基础上进行评估，而不是在代表性研究中进行评估。在这项研究中，WHOQOL-OLD的心理测量特性进行评估的基础上，德国的老年人population.Methods的代表性样本：面对面的访谈，1133名受访者从德国人口年龄在60岁及以上进行。通过WHOQOL-BREF、WHOQOL-OLD和SF 12评估生活质量。此外，GDS，DemTect和IADL被用于评估抑郁症状，认知能力和进行日常活动的能力。心理测量学性质的WHOQOL-OLD的经典和概率测试理论，验证性因素分析和多元回归model.Results：Cronbach的α被发现是0.85以上的四个和两个以上的WHOQOL-OLD的六个方面的.75。IRT分析表明，WHOQOL-OLD的所有项目都对相关方面的测量有很大贡献。虽然WHOQOL-OLD的六面结构得到了验证性因素分析结果的支持，但无法确定WHOQOL-OLD总量表的共同潜在因素。与其他生活质量的措施和多元回归模型与GDS，IADL和DemTect的相关性表明一个良好的标准效度的所有六个WHOQOL-老年人facets.Conclusions：研究结果证实，良好的心理测量性能的WHOQOL-老年人，已被发现在国际研究中可以复制在一个有代表性的研究德国人口。这些结果表明，WHOQOL-OLD是一种非常适合确定老龄化人口需求和愿望的工具。
Background: The WHOQOL-OLD is an instrument for the assessment of subjective quality of life in elderly people. It is based on the WHO definition of quality of life and is available in more than 20 languages. However, in most countries, the psychometric properties of the WHOQOL-OLD have been assessed only on the basis of small local samples and not in representative studies. In this study, the psychometric properties of the WHOQOL-OLD are evaluated based on a representative sample of Germany's elderly population.Methods: Face-to-face interviews with 1133 respondents from the German population aged 60 years and older were conducted. Quality of life was assessed by means of the WHOQOL-BREF, the WHOQOL-OLD and the SF12. Moreover, the GDS, the DemTect and the IADL were applied for the assessment of depressive symptoms, cognitive capacities and capacity for carrying out daily activities. Psychometric properties of the WHOQOL-OLD were evaluated by means of classical and probabilistic test theory, confirmatory factor analysis and multivariate regression model.Results: Cronbach's alpha was found to be above 0.85 for four and above .75 for two of the six facets of the WHOQOL-OLD. IRT analyses indicated that all items of the WHOQOL-OLD contribute considerably to the measurement of the associated facets. While the six-facet structure of the WHOQOL-OLD was well supported by the results of the confirmatory factor analysis, a common latent factor for the WHOQOL-OLD total scale could not be identified. Correlations with other quality of life measures and multivariate regression models with GDS, IADL and the DemTect indicate a good criterion validity of all six WHOQOL-OLD facets.Conclusions: Study results confirm that the good psychometric properties of the WHOQOL-OLD that have been found in international studies could be replicated in a representative study of the German population. These results suggest that the WHOQOL-OLD is an instrument that is well suited to identify the needs and the wishes of an aging population.
