在不同的研究中，报告的晚年抑郁症状的患病率差异很大，这一发现可能归因于文化和方法因素。EURO-D量表的制定是为了对欧洲国家之间的患病率和风险关联进行有效的比较。本研究使用验证性因子分析（CFA）和Rasch模型来评估是否达到了测量不变性的目标；使用在10个欧洲国家收集的EURO-D量表数据，作为欧洲健康、老龄化和退休调查（SHARE）的一部分（n = 22,777）。结果表明，主成分分析（PCA）后，10个国家中有9个国家的双因素解决方案（情感痛苦和动机）。对于CFA，在所有国家，双因素解决方案比单因素解决方案具有更好的整体拟合优度。然而，只有情感痛苦分量表在各国之间是相同的，而动机分量表则不是。Rasch模型表明EURO-D是一个等级量表。虽然校准模式在各国之间是相似的，但国家之间在项目校准方面的一致性对情感痛苦的项目加载比动机因素更强。总之，有证据支持EURO-D作为欧洲各国晚年抑郁症状的单维度或双维度量表测量。情感痛苦分量比动机分量具有更强的跨文化效度。版权所有(C) 2008约翰威利父子有限公司
The reported prevalence of late-life depressive symptoms varies widely between studies, a finding that might be attributed to cultural as well as methodological factors. The EURO-D scale was developed to allow valid comparison of prevalence and risk associations between European countries. This study used Confirmatory Factor Analysis (CFA) and Rasch models to assess whether the goal of measurement invariance had been achieved; using EURO-D scale data collected in 10 European countries as part of the Survey of Health, Ageing and Retirement in Europe (SHARE) (n = 22,777). The results suggested a two-factor solution (Affective Suffering and Motivation) after Principal Component Analysis (PCA) in 9 of the 10 countries. With CFA, in all countries, the two-factor solution had better overall goodness-of-fit than the one-factor solution. However, only the Affective Suffering subscale was equivalent across countries, while the Motivation subscale was not. The Rasch model indicated that the EURO-D was a hierarchical scale. While the calibration pattern was similar across countries, between countries agreement in item calibrations was stronger for the items loading on the affective suffering than the motivation factor. In conclusion, there is evidence to support the EURO-D as either a uni-dimensional or bi-dimensional scale measure of depressive symptoms in late-life across European countries. The Affective Suffering sub-component had more robust cross-cultural validity than the Motivation sub-component. Copyright (C) 2008 John Wiley & Sons, Ltd.
