Summary

This study tested whether adding in-home decluttering practice to a group workshop (Buried in Treasures) helps people with hoarding disorder. 41 adults aged 18-70 took part. The goal was to reduce clutter, difficulty discarding, and excessive acquiring. Results were measured using a questionnaire called the Saving Inventory-Revised.
