The Chronic Sleep Reduction Questionnaire – Review

DEWALD, J. F., SHORT, M. A., GRADISAR, M., OORT, F. J. and MEIJER, A. M. (2012), The Chronic Sleep Reduction Questionnaire (CSRQ): a cross-cultural comparison and validation in Dutch and Australian adolescents. Journal of Sleep Research, 21: 584–594. doi: 10.1111/j.1365-2869.2012.00999.x

Through the use of the Chronic Sleep Reduction Questionnaire (CSRQ), the researchers try to assess symptoms of chronic sleep reduction in adolescents. While this paper is mostly about validating this approach, the information is very useful to see how such experiments are set up, and their conclusions. Also the questionnaire itself can be a useful tool in further research.

The research question of how the CSRQ method compares to other measurements like a survey, sleep diary and actigraphy, is ultimately answered in this conclusion (TST: total sleep time)

as chronic sleep reduction focuses on symptoms of insufficient sleep rather than TST, this measurement is a more promising indicator of the effects of sleep problems on adolescents’ daily functioning than sleep duration.

Which means, I think, that the outcome of the questionnaire more accurately predicts problems in areas like academic performance and psychological wellbeing, than the number of hours these adolescents sleep. Which leaves the question: Why does the CSRQ measure sleep deprivation and not just problem behaviour?

Please tell me what you think!
