The Relation of Sleep Quality to Depression and Anxiety in Obsessive Compulsive Disorder

Abstract

Objective: Obsessive compulsive disorder (OCD) is one of the psychiatric disorders which causes labor loss and seen in between 1-2% of the society. The aim of this study is to compare OCD patients with healthy controls in terms of sleep quality and to investigate the relationship between sleep quality and clinical variables OCD patients. Materials and Methods: Forty-three OCD patients and forty healthy controls were included in the study. The Pittsburgh Sleep Quality index (PSQI), the Beck Depression inventory (BDI), the Beck Anxiety inventory (BAI), and the Yale-Brown obsessive compulsive scale (Y-BOCS) were applied to patients. Results: A significant difference determined between the OCD group and the control group in the mean scores of PSQI, BDI and BAI. There was also a significant difference in sleep quality between each two groups. A statistically significant difference was found between the PSQI total score and all the PSQI subscale scores of the OCD patient group and the control group. A relationship found between the Y-BOCS and PSQI subscales (except for the PSQI duration of sleep and the PSQI sleep disturbance). The PSQI sleep duration and the PSQI sleep disturbance subscales were not associated with the Y-BOCS, but these subscales were related to the BDI and the BAI scores. Conclusion: Sleep quality was found to be associated with disease severity, accompanying anxiety and depressive symptoms in OCD patients.
