A recent taxometric investigation examined the underlying latent structure of hoarding symptoms, and found support for a dimensional solution, in line with the cognitive behavioral conceptualization of hoarding. Yet to date, we still know relatively little about the nature of this spectrum, particularly with respect to the transition point where healthy saving and acquiring behaviors turn pathological. The overarching aim of the current investigation was to characterize the full dimension of hoarding. We examined hoarding symptoms, associated features, and hypothesized cognitive risk factors across individuals with hoarding disorder and healthy controls, as well as collectors and at-risk young adults.

Participants (N=114) included those with hoarding disorder (HD=25), collectors (C=21), matched healthy controls (HC=23), and a group of university students who were characterized as at-risk based on elevated symptoms and a family history of hoarding (HR=43). Our sampling approach resulted in a normally distributed dimension of hoarding symptoms (skew=.08, kurtosis= -1.06), with the HD and HC groups on opposite ends of the spectrum. A series of group-wise comparisons were conducted across variables of interest. The HD, C, and HC groups did not differ on demographics, medication use, and chronic medical conditions; however, the HD group did report significantly more comorbid psychiatric conditions, particularly depression (F=7.8, ppppp>.05), and were significantly lower compared to either the C or HC group. Results will be discussed in light of implications for future research on hoarding, with a focus on prevention, as well as suggestions for refinement of the CBT model.
