Hoarding Disorder Research

The Anxiety Disorders Center at Hartford Hospital/Institute of Living is conducting a study investigating changes in brain functioning after treatment in people with Hoarding Disorder.

Researchers at the Anxiety Disorders Center are offering a treatment study for adults who meet criteria for hoarding disorder. People with hoarding disorder often save or collect too many things and have extreme difficulty throwing things away. This often results in so much clutter that it is difficult to use rooms in their home as they are intended.

In this study, participants will be randomly allocated to an immediate treatment condition or a delayed treatment condition. In the immediate treatment condition, participants will receive cognitive behavioral therapy (CBT) in a group setting with no waiting period beforehand. In the delayed treatment condition, participants will receive the CBT treatment after a 16 week delay. Participants are also required to complete multiple fMRI’s (brain scans) at set intervals throughout the course of the study to examine how the brain responds to different tasks as treatment progresses. The CBT sessions will occur weekly for 16 consecutive weeks and are mandatory for continued enrollment in the study. Participants will be compensated up to $200 for completing the study.

This study is open to adults ages 20 – 60 years old that meet criteria for hoarding disorder as well as other general study criteria.
