====== Sleep reduction (CSRQ) ======

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 ([[sections|section]]: [[Children & adolescents]]) were used to assess sleep loss((DeWald et al. (2012). The Chronic Sleep Reduction Questionnaire (CSRQ): a cross‐cultural comparison and validation in Dutch and Australian adolescents. Journal of Sleep Research 21(5): 584-594)).\\
Furthermore, general questions on [[Sleep (<18)|sleep]] were also asked to underage participants.\\
