Study Summary

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.

Study Description

Sleep is an essential function for physical and mental health. It involves an interaction between homeostatic regulation (need for sleep in the event of deprivation) and circadian regulation (need for sleep according to day-night alternation). Democratized at the end of the 19th century, electric lighting made nocturnal activities possible, and hence the mismatch between individuals' biological and social rhythms (mismatch of rhythms, sleep irregularity, also known as social jetlag). This sleep irregularity is all the more alarming as it is growing epidemically in our societies, and can have numerous consequences on mental health (anxiety, depression), cardiometabolic health (insulin resistance), the immune system (repeated infections), functioning (driving, cognitive performance), 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 health issue, but has never been translated into French.

The investigators make the following assumptions:

  • Cronbach's alpha = 0.87 as in the English version.

  • a two-dimensional structure with a circadian regularity factor and a sleep continuity regularity factor will be confirmed by confirmatory factor analyses.

  • Convergent validity between SRQ results and actimetric measures of sleep regularity (Sleep Regularity Index, intra-individual variability).

The main objective of this study was to translate and validate the French version of the Sleep Regularity Questionnaire (SRQ).

The secondary objectives are to analyze the external validity (convergent and divergent) of the SRQ by calculating :

  • associations with sleep complaints (insomnia, somnolence),

  • mental health complaints (depression, anxiety),

  • sleep behaviors and electroencephalographic parameters (sleep architecture, fragmentation).
