Sleep is an essential function for physical and mental health. The mismatch between biological rhythms and the social rhythms of individuals is increasingly common in modern societies. This sleep irregularity can have numerous consequences on mental health, cardiometabolic health, the immune system, functioning, and quality of life. To address the public health issue of sleep irregularity, it is important to be able to obtain a valid and reliable measure. The Sleep Regularity Questionnaire (SRQ) by Dzierzewski et al. addresses this issue, but has never been translated into French. The aim of the study is to translate and validate the French version of the Sleep Regularity Questionnaire.
