Those who participated in the study were thirty-six Italian seniors in high school. In order to determine their ideal sleep timing, they each filled out the Morningness-Eveningness Questionnaire for Children and Adolescents (MEQ-CA).

This was done in a one month period, and was able to assess factors such as: habitual sleep timing though the midpoint (MS); habitual sleep quality through the parameter of sleep efficiency (SE); and habitual sleep duration through the parameter of total sleep time (TST) (Tonetti, Fabbri, Filardi, Martoni, Natale, 2015). At the end of each actigraphic-recording week, the students completed the Mini Sleep Questionnaire, and their school performance were assessed by the grades achieved after taking final exams. 1.
