Aims To develop a German version of the Dental Environment Stress (DES) questionnaire, and to evaluate its reliability and validity. Methods The original English DES questionnaire was translated into German using a forward–backward translation process. To evaluate construct stability, a subgroup of dental students ( n = 43) completed the DES twice (interval: 1 week). To evaluate how the DES responds to anticipated changes in stress, all dental students' ( n = 64) DES scores and saliva cortisol levels administered from a clinical study were compared between holiday and term time. Furthermore, the Depression, Anxiety and Stress Scale (DASS) and a stress self‐assessment were used to determine the validity of the DES. Reliability analyses were calculated using Kendall's tau correlations. To estimate reliability strength, correlation coefficients and intraclass correlations (ICCs) were used. Results Regarding construct stability, 24 of 25 DES items had at least moderate correlations, and most items showed strong correlations. Correlations for the seven subdomains were good (range: 0.778–1.000). The same was true for the total DES score (ICC: 0.944). Correlations for response to term‐time stress were weaker and more varied. Validity analyses revealed fair correlations between the DES and students' self‐assessment (Pearson's r = .592) and DASS score (Pearson's r = .392), suggesting satisfactory validity. Stress levels were quite similar between baseline and follow‐up. Conclusion The German DES is a reliable tool for evaluating stress in dental students. Because it can be used to identify individual stressors in various categories, it might enable the detection of specific stress situations in educational situations and facilitate solutions (adjustment of curricula, tailored consulting services).
