Study summary

The purpose of this study is to investigate whether a well-established case management model called Critical Time Intervention (CTI) can help individuals with hoarding disorder who are concerned about the risk of eviction. Each individual with hoarding disorder will be assigned to work with a CTI Specialist for 9 months, who will provide referrals for mental health treatment, legal consultations, and registration for entitlements. All participants will be offered a facilitated group intervention called the Buried in Treasures Workshop. The CTI Specialist will also facilitate reconnecting the individual with supportive family/friends and will monitor and support the de-cluttering of the patient's home.

What researchers measure

Primary outcomes

  1. Savings Inventory-Revised

    The Saving Inventory-Revised scale (SI-R) is a 23-item questionnaire with 3 factor-analytically defined sub-scales for difficulty discarding, excessive clutter, and compulsive acquisition. The total score (sum of 23 items) ranges from 0 to 92. Total score higher than 41 shows significant difficulty with clutter. For the acquisition subscale we sum items 2 (reverse score), 9, 11, 14, 16, 18 and 21. The subscale ranges from 0 to 28 and score greater than 13 indicates difficulty with excessive acquisition. For the difficulty discarding subscale we sum items 4(reverse score), 6, 7, 13, 17, 19, 23. The subscale ranges from 0 to 28 and score greater than 13 indicates difficulty with discarding. For the clutter subscale we sum items 1, 3, 5, 8, 10, 12, 15, 20, 22. The subscale ranges from 0 to 36 and score greater than 15 indicates difficulty with accumulated clutter.

    Time frame: Baseline, 3 months, 6 months and 9 months

  2. Clutter Image Rating Scale

    Clutter Image Rating ScaleL Three sets of photographs, each containing nine photos of a single room with varying levels of clutter. A selection is made as to which photograph best resembles their own home. This scale assesses the clutter levels in the bedroom, living room and kitchen. The scale for each room ranges from 1 to 9. Clutter that reaches the level 4 indicates significant difficulty with clutter that affects the person's life.

    Time frame: Baseline, 3 months, 6 months and 9 months
