The Morningness-Eveningness Questionnaire (MEQ) and Munich ChronoType Questionnaire (MCTQ) are sometimes used to estimate circadian timing. However, it remains unclear if they can reflect a change in circadian timing after a light treatment. In this study, 31 participants (25-68 years) completed both questionnaires before and after a 13-28 day morning light treatment. The dim light melatonin onset (DLMO), a physiological marker of circadian timing, was also assessed in a subsample of 16 participants. The DLMO phase advanced on average by 47 minutes (p<0.001). The MEQ score increased by 1.8 points (p=0.046). The MSFsc measure derived from the MCTQ advanced by 8.7 minutes (p=0.17). The shift towards morningness observed in both questionnaires correlated with the phase advance observed in the DLMO (MEQ r=-0.46, p=0.036; MSFsc r=0.81, p<0.001). Results suggest that these circadian questionnaires can change in response to a light treatment, indicating they can reflect underlying changes in circadian timing.
晨型-夜型问卷（MEQ）和慕尼黑生物钟类型问卷（MCTQ）有时用于评估昼夜节律时间。然而，它们是否能反映光照治疗后昼夜节律时间的变化仍不清楚。在本研究中，31名参与者（25 - 68岁）在进行为期13 - 28天的早晨光照治疗前后均完成了这两份问卷。还对16名参与者的子样本评估了暗光褪黑素起始时间（DLMO），这是昼夜节律时间的一个生理指标。DLMO相位平均提前了47分钟（p<0.001）。MEQ得分增加了1.8分（p = 0.046）。从MCTQ得出的MSFsc测量值提前了8.7分钟（p = 0.17）。两份问卷中观察到的向晨型的转变与DLMO中观察到的相位提前相关（MEQ r = -0.46，p = 0.036；MSFsc r = 0.81，p<0.001）。结果表明，这些昼夜节律问卷会因光照治疗而发生变化，表明它们能够反映昼夜节律时间的潜在变化。
