Munich ChronoType Questionnaire (MCTQ)

The MCTQ estimates chronotype based on the midpoint between sleep onset and offset on work-free days (midsleep on free days: MSF), corrected for “oversleep” due to the sleep debt that individuals accumulate over the workweek (MSFsc). This MCTQ-proxy for chronotype is based on the assumption that sleep timing on work-free days is highly influenced by the circadian clock.The MCTQ estimates chronotype based on the midpoint between sleep onset and offset on work-free days (midsleep on free days: MSF), corrected for “oversleep” due to the sleep debt that individuals accumulate over the workweek (MSFsc).
