HADS（医院焦虑和抑郁量表）旨在测量焦虑（HADS焦虑）和抑郁（HADS抑郁）的症状。HADS被广泛使用，但在抑郁症状患病率的因素结构和性别差异方面都显示出模糊的结果。在老年人的非临床样本中，也缺乏对HADS的心理测量评估。本研究的目的是评估65 - 80岁普通人群HADS的因素结构，并检查可能存在的差异项目功能（DIF）与性别有关。这项研究是基于瑞典样本的数据，从65 - 80岁年龄组的总人口中随机抽取（n = 6659）。用验证性因素分析（CFA）检验因素结构。进行有序回归分析，以检测性别的DIF。通过序数和传统Cronbach's alpha检验了可靠性。验证性因素分析表明，两个项目（7和8）交叉负荷的双因素模型具有良好的模型拟合。内部一致性良好，在这两个分量表，测量顺序和传统的阿尔法。所有项目均显示地板效应。对于任何分量表，均未发现关于性别的有意义DIF的迹象。HADS焦虑和HADS抑郁是具有可接受的内部一致性的一维测量，并且在性别方面是不变的。尽管项目7和8存在显著的天花板效应和交叉负荷，但HADS的假设双因素模型可以推荐用于评估65 - 80岁的普通人群的心理困扰。
The HADS (Hospital Anxiety and Depression Scale) aims to measure symptoms of anxiety (HADS Anxiety) and depression (HADS Depression). The HADS is widely used but has shown ambiguous results both regarding the factor structure and sex differences in the prevalence of depressive symptoms. There is also a lack of psychometric evaluations of the HADS in non-clinical samples of older people. The aim of the study was to evaluate the factor structure of the HADS in a general population 65–80 years old and to exam possible presence of differential item functioning (DIF) with respect to sex. This study was based on data from a Swedish sample, randomized from the total population in the age group 65–80 years (n = 6659). Confirmatory factor analyses (CFA) were performed to examine the factor structure. Ordinal regression analyses were conducted to detect DIF for sex. Reliability was examined by both ordinal as well as traditional Cronbach’s alpha. The CFA showed a two-factor model with cross-loadings for two items (7 and 8) had excellent model fit. Internal consistency was good in both subscales, measured with ordinal and traditional alpha. Floor effects were presented for all items. No indication for meaningful DIF regarding sex was found for any of the subscales. HADS Anxiety and HADS Depression are unidimensional measures with acceptable internal consistency and are invariant with regard to sex. Despite pronounced ceiling effects and cross-loadings for item 7 and 8, the hypothesized two-factor model of HADS can be recommended to assess psychological distress among a general population 65–80 years old.
