Background: Hoarding disorder (HD) is a common and debilitating disorder characterized by an accumulation of and failure to discard one's possessions. The identification and examination of underlying factors that may contribute to hoarding symptoms are needed to elucidate the nature of the disorder and refine existing treatments. Two transdiagnostic vulnerability factors that have been associated with hoarding symptoms are distress intolerance (DI) and intolerance of uncertainty (IU).
Objectives: This study examined the relationships between DI, IU, and symptoms of hoarding in two samples consisting of outpatients and individuals recruited from Amazon's Mechanical Turk. We hypothesized that DI and IU would show unique and interactive associations with hoarding symptoms.
Results: Across both samples, DI and IU were significantly associated with hoarding symptoms. However, DI and IU did not interact in their prediction of symptoms, and only IU remained a significant predictor, when accounting for relevant covariates.
Conclusions: Results suggest that IU is a robust predictor of hoarding symptoms and may be a promising and novel treatment target for HD.
