Abstract

Morningness-Eveningness Questionnaire scores correlated negatively with the Midpoint of sleep on free days, with a correlation coefficient of -0.45.

  • Midpoint of sleep on free days, adjusted for weekday sleep debt, was assessed using the Munich Questionnaire.
  • The MCTQ's Midpoint of sleep on free days showed strong positive correlations with sleep diary and actigraphy measures (r=0.74 and r=0.76, respectively).
  • Midpoint of sleep on free days was positively correlated with insomnia (r=0.26), depression (r=0.25), and anxiety (r=0.18).
  • A cut-off score derived from the Morningness-Eveningness Questionnaire was established to differentiate between morning type and other chronotypes in older adults.
