Abstract

The objective of the study was to assess which of three types of lectures are most effective for shifting adolescents to morning-type. Control group to which no lectures were given were observed in parallel conditions. Together in the study 120 adolescents (60 girls, 60 boys) participated, which attended affiliated junior high school. The effects of the class were estimated by an integrated questionnaire on whether the adolescents could participate in the 7 items after the class and a questionnaire on diurnal rhythms (MEQ Torsvall and Åkerstedt, 1980). The questionnaires were administered twice: just before and 1 month after the class. One-by-one comparison of before-class data to after-class one showed that significantly higher increase in Morning-Evening scores and also higher decrease in the frequency to be depressed in the Type 3 class students, than that in the other three classes (P<0.05 in both). Combination of classes of fundamental knowledge about the diurnal rhythms and sleep habits might be effective for preventing of the actual Japanese adolescents shifting to evening-type and for the mental health promotion of the adolescents.
