How Age Affects the Link Between Depression Symptoms and Morning or Evening Preferences

A negative association between eveningness and depressive symptoms was observed, particularly in individuals aged 20s and 50s.

• Eveningness, as measured by the Morningness-Eveningness Questionnaire, is associated with higher depressive symptoms.
• The association was significant in individuals aged 20s (beta=-.31) and 50s (beta=-.38), indicating a stronger link to eveningness.
• No significant association was found in individuals aged 30s and 40s, suggesting age may moderate this relationship.
• The findings indicate that the relationship between depressive symptoms and eveningness varies across different age groups.
