Screen use (<18)
UNDER CONSTRUCTION
Underage participants were asked several questions regarding their hobbies and activities (section: lifestyle & environment).
Note that sports were assessed separately here.
A subcohort of adult participants answered some more detailed questions on daily activities in an additional questionnaire, ACTQ.
The following variables on nighttime screen use (section: lifestyle & environment) were collected in the context of an additional questionnaire on Shiftwork and Screen use (SHIQ).
Of note, the subsection nighttime screen use also includes variables of the additional questionnaire on blue light, which was sent to underage participants and of which the variables can be found on the page Blue Light (BLUQ).
Participants answered several questions on their use of electronic devices (section: lifestyle & environment).
Note that some additional information on electronic device use can be derived from the questions on participants' hobbies & activities. Assessment of mobile phone use can be found here here, and assessment of compulsive use of internet can be found here.
Also note that more detailed questions regarding electronic device use (and their effect on sleeping patterns) were asked to a subcohort of adults in the additional questionnaire on shiftwork (SHIQ) and to a subcohort of children in the additional questionnaire on blue light exposure (BLUQ).
