Assessing chronotype is essential in clinical and research environments, but the
Munich ChronoType Questionnaire (MCTQ), a widely utilised tool, is not available
in French. Therefore, we carried out an observational monocentric study to
validate the French MCTQ against the sleep diary for sleep schedules, the
Morningness-Eveningness Questionnaire (MEQ) for chronotype, and polysomnography
measures. We utilised the mid-sleep point on free days (MSF), adjusted for sleep
debt (MSFsc), to gauge morningness/eveningness. The study included 80
participants (average age: 40.9 years, 50% female). The sleep schedules
determined by the MCTQ and the sleep diary showed a high correlation. The MSFsc
demonstrated a significant correlation with the MEQ, persisting even under sleep
constraints such as an alarm on free days. The predictive accuracy was strong
for a morning chronotype and moderate for an evening chronotype as assessed
using the MEQ. In summary, the French MCTQ is a reliable tool for researchers
and clinicians for assessing sleep schedules and chronotype in French-speaking
populations. The MSFsc can effectively predict chronotype, even under sleep
constraints. However, for the evening chronotype, self-assessment appears to be
more accurate. The association with polysomnography measures enriches our
understanding of the chronotype at the intersection of behaviour and physiology.
