An analysis of the “eveningness–morningness” dimension in “depressive” college students

Among 1617 students identified as 'depressives', evening types were significantly more prevalent than morning types.

• Significant negative correlations were observed between eveningness-morningness scores and depression scale scores (BDI r= -.174, GDS-SF r= -.182, CESD r = -.176, all p < .001).
• The incidence of evening types was significantly higher than that of morning types among depressive students (chi2 = 11.18, p < .01).
• These findings suggest a potential relationship between eveningness and higher levels of depression in this population.
• Generalizability of results to clinical populations remains uncertain.
