Evening preference may harm social life by worsening depression in recovered schizophrenia patients

The eveningness chronotype group exhibited higher depressive symptoms and poorer social functioning than morningness and intermediate groups.

• 185 patients with schizophrenia were categorized into morningness, eveningness, or intermediate chronotypes.
• The eveningness group had higher scores on depression and sleep quality assessments.
• Lower scores in personal and social performance were observed in the eveningness group compared to others.
• The influence of chronotype on social functioning may be mediated by depressive symptoms.
• Inclusion of depressive symptoms reduced the significance of chronotype effects on social functioning.
