Patterns of self-reported depressive symptoms in relation to morningness-eveningness in inpatients with a depressive disorder

Patients with an evening preference had significantly higher Beck Depression Inventory scores at admission compared to those with a morning preference.

• Evening preference is associated with a higher severity of cognitive depressive symptoms in hospitalized patients.
• No significant differences in affective and somatic symptoms were found between morning and evening preference groups.
• Results indicate that chronotype may play a role in the symptomatology of depressive disorders.
• The study analyzed data from 64 patients, with 31 identified as morning preference and 33 as evening preference.
• Both groups were comparable in demographic factors, suggesting that chronotype may independently influence depressive symptoms.
