A new German Charité Jet Lag Scale for jet lag symptoms and application

Travelling across multiple time zones provokes adaptation of endogenous circadian rhythm to the new time zone. Within the context of previous studies, an English-language state-of-health questionnaire, the Columbia Jet Lag Scale, is the only sufficiently validated scale for jet lag and its symptoms. This study presents a new state-of-health questionnaire in German, one intended to achieve standardisation of surveys on jet lag. The questionnaire was applied to define the baseline for the prevalence of jet lag symptoms based on a reference group (n = 36). The jet lag score ascertained was subsequently applied to determine the frequency of jet lag in a group of 53 subjects. Systematic investigation of the frequency of jet lag symptoms had not been previously presented. Among the group of 53 travelling test subjects, 60% demonstrated moderate jet lag symptoms.Practitioner Summary: This introduction of the Charité Jet Lag Scale, the first German jet lag questionnaire, calls attention to this topic for the first time since a 2000 publication in Ergonomics. Our systematic investigation of jet lag frequency, with the new scale, determined moderate jet lag symptoms among 60% of subjects.跨时区旅行可促使机体内源昼夜节律（endogenous circadian rhythm）适配新时区。 既往研究显示，仅英文版《哥伦比亚时差量表》（Columbia Jet Lag Scale）这一健康状况问卷得到充分验证，可用于评估时差反应及其相关症状。本研究开发了一款德文版健康状况问卷，旨在实现时差反应相关调研的标准化。 该问卷首先应用于参照组（n=36），以确立时差症状患病率的基准值；随后通过所得时差评分，对53名受试者群体的时差反应发生频率进行评估。此前尚无针对时差症状发生频率的系统性调研报道。在53名旅行受试群体中，60%表现为中度时差反应症状。 从业者总结：本研究推出首款德文版时差问卷《夏里特时差量表》（Charité Jet Lag Scale），自2000年《Ergonomics》（人类工效学）刊发相关研究以来，首次唤起学界对该主题的关注。本研究借助该新量表开展的时差反应频率系统性调研显示，60%的受试者存在中度时差反应症状。
