Delayed Bedtimes and Obsessive–Compulsive Symptoms

There is increasing recognition of an important interplay between psychiatric disorders and sleep. Clinical observations and several empirical studies have shown that later bedtimes are associated with obsessive-compulsive disorder (OCD). This study examined the relation of delayed bedtimes (DBs) and symptoms of OCD. Two hundred and sixty-six undergraduates completed a battery of questionnaires assessing sleep patterns, mood, and obsessive-compulsive (OC) symptoms. Results showed that participants with DBs reported increased rates of OC symptoms, as compared with non-DB participants. Further, this relation remained significant when controlling for negative affect. Additional work examining the interplay between sleep and OC symptoms is warranted.
