Participants (or the parents of underage participants) were asked several questions regarding sleeping patterns, problems, and habits (section: lifestyle & environment).
Note that sleep was also assessed within Lifelines using the Munich ChronoType Questionnaire, the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale, and participants were asked whether they suffered from insomnia.
Also note that certain subcohorts of participants answered more detailed questions on their sleeping behavior in the additional questionnaires on ADHD and blue light exposure.
Participants in the general cohort were asked the following questions:
