Abstract:
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.
