What is the purpose of this trial?

This trial explores a new treatment strategy called imaginal exposure for individuals with hoarding disorder. Imaginal exposure involves imagining the act of discarding possessions to help reduce the anxiety associated with letting go of items. The study compares this method to a neutral writing activity to determine its effectiveness in improving hoarding symptoms and reducing related issues like fear of uncertainty and emotional avoidance. Individuals with hoarding disorder as their primary condition who are not currently in cognitive behavioral therapy might be suitable for this trial. As an unphased trial, it offers participants the chance to contribute to groundbreaking research that could lead to new treatment options for hoarding disorder.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that imaginal exposure writing is safe for people with hoarding disorder?

Research has shown that imaginal exposure writing for hoarding disorder is safe and well-tolerated. In past studies, this treatment improved hoarding symptoms without causing major side effects, and participants felt comfortable with the process. Although one study found it no more effective than a different writing task, it was still seen as beneficial overall. These findings suggest that imaginal exposure writing is a safe option for people with hoarding disorder. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Imaginal Exposure Writing is unique because it tackles hoarding disorder by having individuals face their fears about discarding possessions through guided writing exercises. Unlike traditional therapies like cognitive-behavioral therapy (CBT), which often require in-person sessions over a longer period, this treatment involves just three short writing sessions, making it more accessible and less time-consuming. Researchers are excited because this method could offer a new, effective way to address the emotional barriers of hoarding with minimal resources and effort.

What evidence suggests that imaginal exposure writing could be an effective treatment for hoarding disorder?

Research has shown that imaginal exposure, a therapy where individuals imagine discarding their belongings, might help reduce hoarding disorder symptoms. In this trial, participants will join either the Imaginal Exposure Writing arm or the Neutral Writing arm. Previous studies indicate that patients find imaginal exposure both manageable and acceptable. Specifically, one study found significant improvement in hoarding symptoms after imaginal exposure therapy, with benefits lasting at least a week. These findings suggest that imaginal exposure could be a promising option for those who find traditional cognitive behavioral therapy challenging. ^{1 2 3 4 6}

What Are the Treatments Tested in This Trial?

Interventions

• Imaginal Exposure Writing
• Neutral Writing

Trial Overview The study tests imaginal exposure therapy where participants imagine discarding items to reduce hoarding symptoms. This approach is compared to neutral writing and aims to ease the discomfort associated with throwing things away.

How Is the Trial Designed?

Group I: Imaginal Exposure Writing Experimental Treatment 1 Intervention

People with hoarding disorder will write for 20 minutes on each of 3 consecutive days about their worst-case scenario regarding discarding a possession (i.e., imaginal exposure).

Group II: Neutral Writing Placebo Group 1 Intervention

People with hoarding disorder will write for 20 minutes on each of 3 consecutive days about what they would do if they had a day off work or school.

Published Research Related to This Trial

A non-inferiority trial is being conducted to compare the effectiveness of group cognitive-behavioral therapy (CBT) and a structured support group called Buried in Treasures (BiT) for treating hoarding disorder, involving 300 participants over 16 weeks.

The primary goal of the study is to assess whether BiT can effectively reduce hoarding symptoms to a level comparable to that of traditional CBT, potentially increasing treatment accessibility for individuals with hoarding disorder.
