Abstract
BackgroundLimited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality.MethodsA cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data.ResultsThe prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P < 0.001) and negative coping style (B = 0.049, P < 0.001) demonstrated a positive association with poor sleep quality, while positive coping style indicated a negative association with poor sleep quality (B = −0.029, P < 0.001). Interactions of negative life events and coping styles with sleep quality were not found (all P > 0.05). The association between negative life events and sleep quality was mediated by negative coping styles.ConclusionsOur results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.
Highlights
Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students
The present study focused on the status of sleep quality and the associations of negative life events and coping styles with sleep quality among Chinese adolescents
We found that (1) poor sleep quality was not rare among these Chinese adolescents, with a prevalence of 26.7%, (2) negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, (3) positive coping style was related to a decreased prevalence of poor sleep quality, and (4) negative coping style mediated the association between negative life events and sleep quality
Summary
Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. Previous studies have researched the relationships among negative life events, coping strategies, and sleep quality in patients [20, 21] or young adults [22], and few studies have examined the relationships in school adolescents, especially junior high school students, who spend most of their time in school. These students are immature in mind and poor in social cognitive ability, but school stressors are difficult to avoid [23], and it is very important to understand the relationships among these three factors for improving students’ sleep problems
