Objective: The objective of this study was to explore the association between morningness-eveningness and the level of depression symptoms in healthy young adults after controlling for variables of sleep quantity, sleep regularity and sleep quality including the perception of problematic sleepiness. Methods: A sample of 1025 students (643 females) aged 18-24 yrs., 1st-4th year of study at University of Zagreb completed a modified version of the School Sleep Habits Survey (Wolfson & Carskadon, 1998), which included the Composite Scale of Morningness (CMS) and Depressed Mood Scale (DSM), to assess circadian preferences and depression symptoms in addition to sleep parameters. Hierarchical multiple regression analysis was performed to predict depression scores with one block of demographic variables (gender, year of study), and four blocks of sleep-related variables including: CSM scores, sleep debt (misalignment between preferred sleep duration and weekday sleep duration), indices of sleep irregularity (bedtime and wake-up time irregularity), indices of sleep quality (night waking, premature awakening, difficulty falling asleep, nightmares/bad dreams, general satisfaction with sleep, day dysfunction due to sleepiness). Results: CSM scores correlated negatively with depression symptoms (r = 0.115, P < 0.001), implying that higher preference for eveningness was associated with more frequent depressive mood. Hierarchical multiple regression analysis showed that CSM scores were independent predictor of depression after controlling for sleep debt and indices of sleep regularity. However, when indices of sleep quality were entered into model, CSM scores were no longer significant predictor of depression symptoms. The best predictors of depression symptoms in the final model were subjects’ perception of day dysfunction due to sleepiness, experience of nightmares or bad dreams and general satisfaction with sleep. Conclusion: The association between eveningness preference and depression symptoms in healthy young adults is not related to insufficient sleep or indices of sleep irregularity. Our results indicate that subjects’ perception of problematic sleepiness and general satisfaction with sleep could be responsible for the relationship between eveningness and depression symptoms.
