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

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Group CBT with IPTBehavioural
Group treatment designed to target relationships with both possessions and people.
| Study group | Role | What they receive |
|---|---|---|
| CBT with IPT | Experimental | Group CBT with IPT will consist of 20 weekly two-hour sessions and has been developed for the proposed study based on the protocols for group CBT for HD and group IPT. Treatment includes strategies from CBT, including cognitive restructuring, behavioral exposures, and organizational strategies, as well as strategies from IPT, including role-play, interpersonal skills building, communication analysis, and decision analysis. Receives: Behavioral: Group CBT with IPT |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in Hoarding Rating Scale (HRS)
The Hoarding Rating Scale is a commonly used measure of hoarding symptoms in which participants rate the severity of their symptoms. Minimum score is 0 and maximum score is 40. Higher scores indicate more severe/worse symptoms.
Measured: Baseline, 10 weeks, 20 weeks, 24 weeks
Changes in Reciprocal Attachment Questionnaire Adapted (RAQ-A)
The Reciprocal Attachment Questionnaire Adapted assesses attachment to one's belongings, with higher scores indicating greater attachment to possessions (i.e., worse outcome). Minimum score is 75 and maximum score is 375.
Measured: Baseline, 10 weeks, 20 weeks, 24 weeks
Changes in Adult Attachment Scale (AAS)
The AAS is a measure of two dimensions proposed to underlie interpersonal attachment security: anxiety and avoidance. Higher scores indicate worse outcomes. Minimum score is 0 and maximum score is 72.
Measured: Baseline, 10 weeks, 20 weeks, 24 weeks
Changes in Interpersonal Needs Questionnaire (INQ)
The INQ is a measure of two interpersonal risk factors, namely perceived burdensomeness and thwarted belongingness, with higher scores indicating higher levels of each construct (i.e., worse outcome). Minimum score is 15 and maximum score is 105.
Measured: Baseline, 10 weeks, 20 weeks, 24 weeks
