Longitudinal association between chronotype and depressive symptoms among college students: Mediating roles of perceived stress and self-control.
This study aims to explore the longitudinal relationship between chronotype and depressive symptoms and the mediating roles of perceived stress and self-control among college students. A total of 11,010 college students completed two web-based surveys during 17 to 29 October 2023 (Time 1, T1) and 15 to 24 April 2024 (Time 2, T2), respectively. Participants completed the reduced version of morningness-eveningness questionnaire, the 10-item Perceived Stress Scale, the Brief Self-Control Scale, the 2-item Patient Health Questionnaire, and 3 items of the Youth Self-Rating Insomnia Scale. The results indicated that perceived stress (T1) and self-control (T2) serially mediate the relationship between morning chronotype (T1) and depressive symptoms (T2) (β = -0.010, 95% CI: -0.012 to -0.009), after controlling for baseline sample characteristics, depressive symptoms (T1), and insomnia symptoms (T2). This longitudinal relationship was observed in both male (β = -0.009, 95% CI: -0.012 to -0.006) and female (β = -0.011, 95% CI: -0.013 to -0.009) participants. These findings enhance our understanding of the mechanisms by which chronotype affects college students' depressive symptoms, providing valuable insights for developing targeted interventions, such as stress-management workshops, to mitigate depression risk, especially among students with evening chronotypes.
期刊介绍:
Chronobiology International is the journal of biological and medical rhythm research. It is a transdisciplinary journal focusing on biological rhythm phenomena of all life forms. The journal publishes groundbreaking articles plus authoritative review papers, short communications of work in progress, case studies, and letters to the editor, for example, on genetic and molecular mechanisms of insect, animal and human biological timekeeping, including melatonin and pineal gland rhythms. It also publishes applied topics, for example, shiftwork, chronotypes, and associated personality traits; chronobiology and chronotherapy of sleep, cardiovascular, pulmonary, psychiatric, and other medical conditions. Articles in the journal pertain to basic and applied chronobiology, and to methods, statistics, and instrumentation for biological rhythm study.
