Abstract

The Chronic Sleep Reduction Questionnaire is a validated questionnaire that measures symptoms of prolonged insufficient and/or poor sleep and therefore accounts for individuals' sleep need and sleep debt. This study extends its psychometric properties by providing cut-off scores, using a matched sample of 298 healthy adolescents (15.38 +/- 1.63years, 37.9% male, mean Chronic Sleep Reduction Questionnaire score: 32.98 +/- 6.51) and 298 adolescents with insomnia/delayed sleep-wake phase disorder (15.48 +/- 1.62years;37.9% male, mean Chronic Sleep Reduction Questionnaire score: 42.59 +/- 7.06). We found an area under the curve of 0.84 (95% confidence interval: 0.81-0.87). Cut-off scores for optimal sensitivity, optimal specificity and based on Youden's criterion are provided. These cut-off scores are highly relevant for use of the Chronic Sleep Reduction Questionnaire in future studies and clinical practice.
