The experience and impact of intrusive thoughts in individuals with late bedtimes

There is increasing awareness of the interplay among sleep, circadian rhythms, and psychopathology. Recent findings show that obsessive–compulsive disorder (OCD) is associated with late bedtimes. Sleep disruption may exacerbate impairments in executive functioning in individuals with OCD, making these individuals vulnerable to experiencing intrusive thoughts that come from “out of the blue” (autogenous obsessions; AO) and to having difficulty dismissing them. The current study investigated types of intrusive thoughts experienced by individuals with (DB) and without (NDB) delayed bedtimes. Bedtime, and AO (uncued, affectively negative) vs. reactive obsessions (RO; triggered by environment, affectively neutral) were examined in 212 adults. As hypothesized, individuals with DB reported more frequent intrusive thoughts, as well as more AO, than NDB individuals. Additionally, DB participants reported a greater urge to neutralize intrusive thoughts than NDB participants. Future work should test the replicability of these findings and explore circadian disruptions in OCD using biological markers.
