Supporting data for "Circadian Rhythm and Insomnia in Youths"

The folder contains six datasets used in the PhD thesis titled “Circadian Rhythm and Insomnia in Youths” by CHEUNG Tin Wai Forrest; each dataset corresponds to one study in the thesis. Dataset 1 (for Study 1) contained the processed data extracted from a systemic review used in the meta-analysis. Dataset 2 (for Study 2) contained cross-sectional data on sleep patterns and chronotype (timing of sleep and wake) in a group of Hong Kong youths. Dataset 3 (for Study 3) contains data on circadian characteristics (measured by questionnaire, actigraphy, and dim-light melatonin onset assessment) in patients with insomnia and delayed sleep-wake phase disorder. Dataset 4 (for Study 4) contains the same group of participants as Dataset 3, including variables on polysomnography parameters and processed data on electroencephalogram band power. There are two datasets for Study 5 (long and wide format). Both datasets contain data for an intervention study conducted on insomnia patients with evening chronotype. Data included patient’s self-report questionnaire, clinical-rated measures, notes from clinical interviews, sleep diary, and actigraphy data.
