Background: This research examined gender variations in depressive mood for high school students affected by emotional upset and how such depressive mood affect their sleep quality.

Methods: This research was conducted for 2 months from September 2015 to October 2015. Both males and females were divided into normal group and depressive group by Zung Self-rating Depression Scale (ZSDS). Each group adopted the Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality. Chi-Square test and AVOVA analysis through SPSS-21 were used as statistics methods.

Results: Analysis was made on a total of 155 students (83 male, 72 female students) that submitted clear answers to the questionnaire. There were 86 students in the normal group and 69 students on the depressive group according to the ZSDS. More female students had depressive mood than male students with 52.8% and 37.3% respectively but without particular statistical meaning. The average ZSDS for all high school students was 43.38 and the average PSQI was 5.39. The number of male students in the normal and depressive group who were diagnosed with sleep disorder were 2 (3.8%) and 9 (29.0%) respectively. But the number of female students in the normal and depressive group who were diagnosed with sleep disorder were 11 (32.4%) and 33 (86.8%) respectively, which was quite meaningful result. Both males and females shared a meaningful result over sleep latency, sleep disturbance, use of sleep medication, and daytime functional disturbance among 7 items of PSQI for sleep quality, and female students had a significantly meaningful result over sleep duration, habitual sleep effects.

Conclusions: This research showed that sleep quality of all high school students was not too bad but it can be problematic for those with depressive mood. Especially, female students with hormone changes and emotional instability were diagnosed with sleep disorder more than male students.
