Background The assessment of sleep quality in critically ill patients is a relevant factor of high‐quality care. Despite the fact that sleep disturbances and insufficient sleep management contain an increased risk of severe morbidity for these patients, a translated and applicable instrument to evaluate sleep is not available for German‐speaking intensive care settings. Aim This study aimed to translate the Richards Campbell Sleep Questionnaire ( RCSQ ), a simple and validated instrument eligible for measuring sleep quality in critically ill patients, and subsequently to evaluate the internal consistency of the German version of the RCSQ . Furthermore, it also aimed to inquire into the perception of sleep in a sample of critically ill patients. Methods The RCSQ was translated following established methodological standards. Data were collected cross‐sectionally in a sample of 51 patients at 3 intensive care units at a university hospital in Germany. Results The German version of the RCSQ showed an overall internal consistency (Cronbach's alpha) of 0·88. The mean of the RSCQ in the sample was 47·00 ( SD ± 27·57). Depth of sleep was rated the lowest and falling asleep again the highest of the RCSQ sleep items. Conclusion The study demonstrated very good internal consistency of the German version of the RCSQ , allowing for its application in practice and research in German‐speaking countries. Quality of sleep perception was generally low in this sample, emphasizing the need for enhanced care concepts regarding the sleep management of critically ill patients. Relevance to clinical practice Assessment of self‐perception of sleep is crucial in order to plan an individually tailored care process.
