| Abstract: | Hoarding disorder (HD ), a new DSM ‐5 classification, is characterized by difficulty discarding and the excessive acquisition of possessions to the extent that living spaces are compromised by clutter. Individuals with hoarding difficulties have a variety of motivations for object ownership, including emotional attachment towards their possessions which sometimes manifests through imbuing possessions with human‐like terms. Limited extant evidence suggests that anthropomorphism, attributing human qualities to non‐human objects, is related to hoarding, possibly because of difficulties with interpersonal attachment and social isolation. The current study investigated the relationship between hoarding behaviors (i.e., difficulty discarding, excessive acquisition, and clutter), hoarding beliefs (i.e., motivations for ownership including responsibility, emotional attachment, memory, control), anthropomorphism (i.e., generally in childhood, generally in adulthood, and towards three different personally‐owned objects), and loneliness. Moderation analyses examined whether hoarding beliefs or loneliness impacted how anthropomorphism related to hoarding symptoms. Results suggested that all dimensions of anthropomorphism were related to hoarding behaviors. Regression analyses indicated that anthropomorphism in adulthood and of personally owned‐objects were the best predictors of hoarding behavior. Mixed evidence was found for hoarding beliefs and loneliness moderating these associations. Findings successfully replicated and extended previous literature and provide a novel measure of anthropomorphism specifically incorporating personal ownership. |
