Background: The role of chronotype, the individual timing of sleep/activity, has been studied in relation to depressive and anxiety disorders. A cross-sectional association between a depressive episode and evening-type has been identified. However, until now the predicting capacity of chronotype concerning persistence of psychiatric disorders remains unclear. Our aim is to examine whether a later chronotype in patients with a depressive and/or anxiety disorder can serve as a predictor of a persistent course.

Methods: A subsample of patients with a depressive and/or anxiety disorder diagnosis and chronotype data of the longitudinal Netherlands Study of Depression and Anxiety (NESDA) was used. Diagnosis of depressive and anxiety disorders (1-month DSM-IV based diagnosis) were determined at baseline (n=505). From this group persistence was determined at 2-year (FU2) (persistent course: n=248, non-persistent course: n=208) and 4-year follow-up (FU4) (persistent course: n=151, non-persistent course: n=264). Chronotype was assessed at baseline with the Munich Chronotype Questionnaire.

Results: A later chronotype did not predict a persistent course of depressive and/or anxiety disorder at FU2 (OR (95% CI)=0.99 (0.83-1.19), P=0.92) or at FU4 (OR (95% CI)=0.94 (0.77-1.15), P=0.57).

Limitations: Persistence was defined as having a diagnosis of depressive and/or anxiety disorder at the two-year and four-year follow-up, patients may have remitted and relapsed between assessments.

Conclusion: Chronotype, measured as actual sleep timing, of patients with a depressive or anxiety disorder did not predict a persistent course which suggests it might be unsuitable as predictive tool in clinical settings.
