Design outcomes

Primary

MeasureTime frame
1. Salivary cortisol (as a biomarker for stress) measured by ELISA at T2-T5 2. Salivary melatonin (as a biomarker for circadian rhythm) measured by ELISA at T2-T5 2. Daytime sleepiness assessed using the Pediatric Daytime Sleepiness Scale (PDSS, German translation) questionnaire at T1- T5 T1 = baseline, March 20; T2 = June 2015; T3 = November 2015; T4 = March 2016; T5 = June 2016.

Secondary

MeasureTime frame
1. Attention and concentration assessed using the d2-Revision (d2-R) test at T1-T5 2. Health-related quality of life in children assessed using the KINDL-R questionnair at T1-T5 3. Stress processing assessed using the German Coping Questionnaire for Children and Adolescents (SVF-KJ) questionnaire at T1-T5 4. Participant's assessment of stress measured using an inverse visual analogue scale measured every week during the intervention period of 3 semesters 5. Participant's assessment of daytime sleepiness measured using an inverse visual analogue scale measured every week during the intervention period of 3 semesters 6. Participant's assessment of concentration measured using an inverse visual analogue scale measured every week during the intervention period of 3 semesters 7. Participant's assessment of wellbeing measured using an inverse visual analogue scale measured every week during the intervention period of 3 semesters 8. Participant's assessment of fatigue measured using an inverse visual analogue scale measured every week during the intervention period of 3 semesters 9. Daylight and artificial light composition measured using a spectrometer continuously throughout the intervention 10. Indoor carbon dioxide concentration measured using a CO2-meter continuously throughout the intervention 11. Room temperature measured using a digital hygro-thermometer continuously throughout the intervention 12. Relative humidity measured using a digital hygro-thermometer continuously throughout the intervention 13. Power consumption measured using a power meter continuously throughout the intervention T1 = baseline, March 20; T2 = June 2015; T3 = November 2015; T4 = March 2016; T5 = June 2016.
