Abstract
A significant mediation effect was observed where chronotype influenced depressive symptoms through insomnia severity in older adults with depression.
- Chronotype, as measured by the Morningness-Eveningness Questionnaire, is linked to depression severity in older adults.
- Insomnia severity, assessed with the Insomnia Severity Index, fully mediates the relationship between chronotype and depressive symptoms.
- Sleep hygiene practices are associated with the interplay between chronotype and insomnia severity.
- Both depressive symptoms and sleep hygiene act as partial mediators in the relationship between chronotype and insomnia severity.
