以前的研究已经确定了差异项目功能（DIF）的抑郁症状的措施，但DIF的影响很少报道。鉴于抑郁症状评估在老年人中的重要性，我们研究了由于人口统计学特征导致的DIF是否会导致常用措施的显着评分变化。四项认知老化的纵向研究提供了3，754名老年人的样本量，包括有和没有临床诊断为重度抑郁症的个体。每项研究至少采用以下一种测量方法：流行病学研究中心抑郁量表（CES-D; 20项有序反应或10项二分反应版本）、老年抑郁量表（GDS）和蒙哥马利-卡斯伯格抑郁评定量表（MADRS）。混合逻辑回归-项目反应理论方法被用来检查DIF的存在和影响，由于年龄，性别，种族/民族，和多年的教育对抑郁症状的项目。虽然由于人口统计学因素，DIF在几个项目上存在统计学显著性，但其对抑郁症状评分的累积影响几乎可以忽略不计。研究结果支持了先前报道的老年人抑郁症状的人口统计学差异的实质意义，表明这些个体差异不太可能是由于我们研究的人口统计学特征引起的项目偏倚。
Previous studies have identified differential item function (DIF) in depressive symptoms measures, but the impact of DIF has been rarely reported. Given the critical importance of depressive symptoms assessment among older adults, we examined whether DIF due to demographic characteristics resulted in salient score changes in commonly used measures. Four longitudinal studies of cognitive aging provided a sample size of 3,754 older adults, and included individuals both with and without a clinical diagnosis of major depression. Each study administered at least one of the following measures: the Center for Epidemiologic Studies Depression scale (CES-D; 20-item ordinal response or 10-item dichotomous response versions), the Geriatric Depression Scale (GDS), and the Montgomery-Åsberg Depression Rating Scale (MADRS). Hybrid logistic regression-item response theory methods were used to examine the presence and impact of DIF due to age, sex, race/ethnicity, and years of education on the depressive symptoms items. Although statistically significant DIF due to demographic factors was present on several items, its cumulative impact on depressive symptoms scores was practically negligible. The findings support substantive meaningfulness of previously reported demographic differences in depressive symptoms among older adults, showing that these individual differences were unlikely to have resulted from item bias attributable to demographic characteristics we examined.
