Brief Summary

This study assesses the effectiveness of a novel group treatment for hoarding disorder.

Detailed Description

The primary aim of this study is to investigate the effectiveness of a novel group treatment for hoarding disorder. Participants will be randomized to receive either treatment as usual (cognitive behavioral therapy: CBT) or treatment as usual augmented by interpersonal psychotherapy (IPT). It is hypothesized that group CBT with IPT will result in greater decreases in hoarding symptoms, as compared to standard group CBT. It is further hypothesized that CBT with IPT will result in greater reductions in object attachment and maladaptive beliefs about relationships with others, as well as greater increases in interpersonal attachment.

Minimum score is 15 and maximum score is 105.
Changes in Hoarding Rating Scale (HRS)	Baseline, 10 weeks, 20 weeks, 24 weeks	The Hoarding Rating Scale is a commonly used measure of hoarding symptoms in which participants rate the severity of their symptoms.
