Abstract

Purpose: Assessing olfactory function is highly significant in clinical practice, particularly in the context of the recent COVID-19 pandemic. Recent approaches in this field emphasize the importance of reducing the time and cost devoted to olfactory testing procedures. Hence, the aim of the present study was to examine the reliability and basic characteristics of Digital Scent Device 20 (DSD-20), an innovative olfactory test consisting of 20 "universal odors", in a European population.

Methods: A total of 88 participants (mean age = 45.1, SD = 20.3) volunteered for the study. The sample consisted of 37 normosmic controls and 51 dysosmic patients.

Results: The correlation between DSD-20 and the total score in Sniffin' Sticks was high (TDI; R = .80, p < .001), and the test correlated with the individual components of the Sniffin' Sticks test. Furthermore, the correlation coefficient between DSD-20 test and retest was very high (R = .88, p < .001), which was additionally confirmed by a Bland-Altman plot. Essential characteristics of the DSD-20 are its simplicity in self-administration, speed of application, portability, and the fact that it can be reused.

Conclusion: Overall, the present study confirms previous notions on DSD-20 by demonstrating its high reliability and usefulness in separating patients with hyposmia/anosmia and normosmic controls.

数字气味装置 20：一种自动、自我管理的气味识别测试。

目的：评估嗅觉功能在临床实践中意义重大，尤其是在最近 COVID-19 大流行的情况下。该领域的最新方法强调了减少嗅觉测试程序所需的时间和成本的重要性。因此，本研究的目的是在欧洲人群中检验数字气味设备 20（DSD-20）的可靠性和基本特征，这是一种创新的嗅觉测试，包含 20 种 "通用气味"：共有 88 名参与者（平均年龄 45.1 岁，标准差 20.3 岁）自愿参与研究。样本包括 37 名正常对照组和 51 名嗅觉障碍患者：结果：DSD-20 和嗅觉棒总分之间的相关性很高（TDI; R = .80, p 结论：DSD-20 和嗅觉棒总分之间的相关性很高（TDI; R = .80, p 结论）：总体而言，本研究证实了之前关于 DSD-20 的观点，证明其在区分嗅觉减退/嗅觉缺失患者和正常对照组方面具有很高的可靠性和实用性。
