Enhancing Treatment of Hoarding Disorder With Personalized In-Home Sorting and Decluttering Practice

Study Overview
=================
Brief Summary
-----------------
The proposed study aims to investigate the efficacy of adding in-home decluttering practice to Buried in Treasures Workshop (BIT) facilitated group treatment for hoarding disorder.

Detailed Description
-----------------
Patients participate in Buried in Treasures Workshop (BIT) that has been shown to improve symptoms of hoarding disorder. The investigators hypothesize that adding in-home decluttering practice to the BIT workshop will decrease hoarding symptoms and level of clutter over time.
