A questionnaire to determine circadian typology in adolescence
The aim of the present work was to propose an Italian version of a questionnaire to determine circadian typology in adolescence. Based on previous research, we chose to replicate the results obtained with MEQ-A, and to evaluate two new questionnaires: the reduced version of the MEQ-A and the DTS-A. 3018 students, aged between 11 and 16 years, took part in the research. 1393 students completed the MEQ-A, 876 the MEQr-A, and 749 the DTS-A. On the whole, results confirmed that MEQ-A is the best questionnaire to determine circadian typology in adolescence. The next step should consider a validation with external criteria.
