title: Obsessive-compulsive symptom dimensions and insomnia: The mediating role of anxiety sensitivity cognitive concerns.
abstract: Existing research on the relationship between obsessive-compulsive disorder (OCD) and insomnia is scarce. Moreover, no research has examined potential mechanisms that may account for the observed relations among OCD and sleep difficulties. The cognitive concerns subscale of anxiety sensitivity (AS), which reflects fears of mental incapacitation, has been linked to both symptoms of OCD and insomnia and may serve as a mechanism for increasing sleep disturbance among patients with OCD. The current study examined the relationship between OCD symptoms and insomnia and the potential mediating role of AS cognitive concerns. The sample consisted of 526 individuals recruited through Amazon's Mechanical Turk (Mturk), an online crowdsourcing marketplace. Results revealed distinct associations between the unacceptable thoughts domain of OCD and symptoms of insomnia. Additionally, AS cognitive concerns mediated the relationship between these constructs. Future research should seek to replicate these findings using clinical samples and prospective designs.
