An Initial Investigation of the Relationship Between Insomnia and Hoarding.

Objective: Insomnia has been shown to have profound negative consequences on multiple aspects of daily functioning. Despite increased interest in the association between insomnia and psychopathology, no research has examined the relationships between insomnia and hoarding. The aim of the current investigation was to examine the associations between insomnia and hoarding severity.

Methods: Participants consisted of patients with hoarding disorder (n = 24).

Results: Results revealed that insomnia was a significant predictor of increased hoarding severity. In addition, when examining the relationships among insomnia and specific hoarding symptoms, sleep difficulties were associated with increased acquiring and difficulty discarding behaviors.

Conclusions: These findings add to a growing body of literature on insomnia and various forms of psychopathology, as well as research on symptoms related to hoarding. Reducing insomnia symptoms among hoarders may help to reduce hoarding-related behaviors and increase treatment efficacy.
