Traumatic and stressful life events in hoarding: the role of loss and deprivation

Abstract

Background: Although past research shows hoarding to be associated with stressful life events involving loss and/or deprivation, the temporal relationship between the onset of symptoms and these events is not completely clear. Objectives: In a cross-sectional online study, we examined the relationship between the number of events involving loss or deprivation before/simultaneously vs. after the onset of hoarding and various hoarding-related beliefs, such as emotional attachment to possessions, and symptom severity. Further, we examined whether perceived social support moderated the influence of these events on emotional attachment to objects. Methods: One hundred seventeen subjects with hoarding problems responded to a series of instruments to assess the history and timing of traumatic and stressful loss and/or deprivation in relation to the onset of hoarding, and self-report tools evaluating the severity of hoarding, beliefs/motivations, depression, anxiety, general distress, and perceived social support. Results: The number of events involving loss or deprivation occurring before hoarding was related to increased emotional attachment to possessions, whereas events happening after the onset of hoarding were related to increased concerns about memory as drivers of hoarding symptoms. Events happening before hoarding did not interact with perceived social support to influence emotional attachment to objects. Conclusions: The timing of traumatic and stressful life events related to loss and deprivation is associated with different hoarding phenotypes, including beliefs/motivations for hoarding. If confirmed by longitudinal studies, these findings may be relevant for therapeutic and preventive measures.
