We explored the relationship between circadian preference and perceived quality of the sleep/wake cycle in Italian high school students aged between 14 and 18 years. Three hundred and forty-five participants (299 females, 46 males) were administered the Morningness-Eveningness Questionnaire for Children and Adolescents (MEQ-CA) and the Mini Sleep Questionnaire (MSQ) to determine circadian preference and subjective quality of the sleep/wake cycle, respectively. The MSQ includes two main factors: sleep and wake; lower scores on these two factors correspond to a poorer quality of sleep and wake. Evening-type adolescents scored significantly lower than morning types on the wake factor. No significant effect of circadian preference was observed regarding the sleep factor. Our results suggest that Eveningness preference is significantly and negatively related to the perceived quality of the wake factor of Italian high school students.
