BACKGROUND/AIMS: A timely diagnosis of dementia is important, and the Cognitive Function Instrument (CFI) is a newly developed instrument to screen for cognitive decline. The aim of this study was to evaluate the validity and internal consistency of the Norwegian version of the CFI.
METHODS
We included 265 participants with dementia, mild cognitive impairment (MCI), subjective cognitive impairment (SCI), and a reference group without subjective or assessed cognitive decline. The participants and their relatives answered the self- and proxy-rated versions of the CFI.
RESULTS
The Norwegian CFI had power to discriminate between people with dementia and with MCI, SCI, and the reference group. The proxy version had better power than the self-rated version in our participants (area under the curve [AUC] proxy-rated varying from 0.79 to 0.99, AUC self-rated varying from 0.56 to 0.85).
CONCLUSION
The Norwegian CFI was found to be a useful, valid, and robust instrument.
背景/目的：及时诊断痴呆症很重要，认知功能量表（CFI）是一种新开发的用于筛查认知衰退的工具。本研究的目的是评估挪威语版CFI的有效性和内部一致性。
方法
我们纳入了265名患有痴呆症、轻度认知障碍（MCI）、主观认知障碍（SCI）的参与者以及一个无主观或经评估无认知衰退的参照组。参与者及其亲属回答了CFI的自评版和代理评版。
结果
挪威语版CFI有能力区分患有痴呆症、MCI、SCI的人群以及参照组。在我们的参与者中，代理评版比自评版具有更好的区分能力（代理评版的曲线下面积[AUC]在0.79至0.99之间，自评版的AUC在0.56至0.85之间）。
结论
挪威语版CFI被发现是一种有用、有效且可靠的工具。
