====== Electronic device use ======

Participants answered several questions on their use of electronic devices ([[sections|section]]: [[lifestyle & environment]]).\\
Assessment of mobile phone use can be found here [[Mobile phone use (MOB)|here]], and assessment of compulsive use of internet can be found [[Internet use (CIUS)|here]]. Note that questions on this topic have been asked to child participants as well, see subsections [[Hobbies & Activities (<18)]] and [[Screen use (<18)]].
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 assessments|additional questionnaire]] on shiftwork ([[SHIQ]]) and to a subcohort of children in the additional questionnaire on blue light exposure ([[BLUQ]]).
