In an additional assessment on blue light exposure and sleep quality in underage participants (BLUQ), the ‘loss of energy’ and ‘sleepiness’ scales of the Chronic Sleep Reduction Questionnaire (section: Children & adolescents) were used to assess sleep loss1).
Furthermore, general questions on sleep were also asked to underage participants.
