BITS Clinical Study

Building Community-Academic Partnerships For Evidence Based Treatment of Hoarding Disorder


Hoarding disorder (HD) is a highly disabling condition in which individuals have persistent difficulty parting with personal possessions, which results in clutter and inability to use the rooms in the home for their intended use. It causes public health problems when clutter attracts pest infestations or obstructs fire exits in apartment buildings, endangering both personal and neighbors’ safety. 

Better treatments are needed to prevent the morbidity of hoarding disorder. Buried in Treasures Workshop (BIT) has been shown to improve symptoms of hoarding disorder including decreasing acquiring and improving difficulty discarding.

Purpose: To test the feasibility of adding ten in-home decluterring sessions (2 hours per session) to the BIT workshop. We will 
assess whether this intervention will reduce both hoarding symptoms and clutter.

This clinical study is funded by the Department of Psychiatry and Behavioral Sciences of Stanford University and the National Institute of Health.
