背景：疲乏症状常见于癌症患者。评估疲劳的一种测试是多维疲劳量表(MFI-20)。它已经成功地应用于特定的癌症患者群体。然而，到目前为止，基于人口的正常值仍然缺失。方法：我们对德国成年人群中具有代表性的样本进行了调查，其中包括2,037名年龄在14-92岁的受试者。结果：MFI-20的5个子量表(一般疲劳、躯体疲劳、活动减少、动机减少、精神疲劳)的信度令人满意。MFI-20各分量表与EORTC生活质量问卷疲劳量表的相关分析表明，二者具有较好的一致性效度。作为一个重要的结果，我们发现MFI-20的所有分量表都显示出明显的、近乎线性的年龄依赖关系，老年人的疲劳值更高(p
Background: Fatigue symptoms are often found in cancer patients. One test to assess fatigue is the Multidimensional Fatigue Inventory (MFI-20). It has been successfully applied to specific groups of cancer patients. However, until now population-based norm values are missing. Methods: We conducted an investigation on a representative sample of the adult German population, which comprised 2,037 subjects aged 14-92 years. Results: The reliability of the 5 MFI-20 subscales (general fatigue, physical fatigue, reduced activity, reduced motivation, and mental fatigue) is satisfying. The correlations between MFI-20 subscales and the fatigue scale of the quality-of-life questionnaire EORTC indicate convergent validity. As an important result we found that all subscales of the MFI-20 showed a clear and nearly linear dependency on age with higher fatigue values for older subjects (p
