About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Facilitated group therapy for hoarding disorder with behavioral practice

Primary outcomes

  1. Number of Patients Who Met and Exceeded Response Criteria of the Saving Inventory-Revised (SI-R)

    Time frame: Change from baseline (pre-treatment) to week 18 (post-treatment) the Immediate Treatment Arm/Group and change from baseline (pre-treatment at 18 weeks) to 36 weeks (post-treatment) for the Delayed Treatment Arm/Group

    The SI-R is a 23-item questionnaire with 3 sub-scales for difficulty discarding, excessive clutter, and compulsive acquisition.

    The total score ranges from 0 to 92. The greater the score, the more severe the hoarding symptoms. Total score higher than 41 shows significant difficulty with clutter.

    For the acquisition subscale, items 2 (reverse score), 9, 11, 14, 16, 18 and 21 are summed together. The subscale ranges from 0 to 28 and score greater than 13 indicates difficulty with excessive acquisition.

    For the difficulty discarding subscale, items 4(reverse score), 6, 7, 13, 17, 19, 23 are summed together. The subscale ranges from 0 to 28 and score greater than 13 indicates difficulty with discarding.

    For the clutter subscale, items 1, 3, 5, 8, 10, 12, 15, 20, 22 are summed together. The subscale ranges from 0 to 36 and score greater than 15 indicates difficulty with accumulated clutter.

    Response was defined as at least a 14 point change (pre-post) in the total score.
