Interpersonal attachment, early family environment, and trauma in hoarding: A systematic review.

The formation of intense emotional attachments to objects, difficulty parting with possessions, and the extreme accumulation of clutter are key features of Hoarding Disorder (HD). Although substantial literature implicates processes such as dysfunctional beliefs and maladaptive emotional cycles in HD, little is known about the vulnerability factors that lead to their development and hoarding symptomatology. The current review sought to systematically collate and integrate findings from studies investigating the relationship between hoarding symptoms and three proposed vulnerability factors: i) interpersonal attachment, ii) early family environment, and iii) traumatic or adverse life events.
