Brief Summary

Aim 1: To test the efficacy of contingency management for patients with hoarding disorder (HD). Hypothesis 1. Participants completing CM will show significant pre- to post-treatment decreases in severity of hoarding symptoms and clinician-rated impairment, and significant increases in quality of life. Exploratory analyses will examine whether effect sizes compare with those of prior trials of cognitive-behavioral therapy (CBT) for HD conducted within our clinic, whether problem severity at follow-up is predicted by hoarding severity measured immediately after treatment completion, and whether readiness for change improves with treatment.

Outcome Measures

Primary Outcomes (2)

• Hoarding Rating Scale (HRS)

  A brief 5-item interview to rate clutter, difficulty discarding, acquisition, distress, and impairment. Each item is rated on a likert scale from 1 to 8, with higher scores reflective of higher symptom severity.

  Change from week 1 (pre) to week 16 (post)

• Clutter Image Rating Scale

  A pictorial measure of clutter severity containing nine photographs depicting increasing levels of clutter. CIR Scores can range from 1 to 9, with picture 1 indicating an absence of clutter and 9 indicative of the highest level of clutter. Each available room will be rated.

  Change from week 1 (pre) to week 16 (post)

Secondary Outcomes (2)

• Readiness Ruler

  Change from week 1 (pre) to week 16 (post)

• The World Health Organization Quality of Life Scale (WHOQOL-BREF)

  Change from week 1 (pre) to week 16 (post)

Contingency Management

EXPERIMENTAL

Receives contingency payments each month based on decluttering scores

Behavioral: Contingency Management

Interventions

Contingency Management BEHAVIORAL

Participants in the current study will receive contingencies for improvement in clutter, as measured by a trained, independent in-home rater. Ratings will be completed by after study consent, and once every month thereafter, being conducted at weeks 0, 4, 8, 12, and 16 of treatment. Participants will be reimbursed for each new 1-point reduction in CIR score, a set dollar amount per month for each CIR point reduction they maintain from baseline. Therefore, a perfectly performing patient would earn reimbursement (A CIR reduction of 8 points made in the first month and maintained throughout treatment. If a CIR score is higher than the prior month, the reinforcement schedule will reset to zero.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Diagnosed with Primary Hoarding Disorder,
• currently participating in the Hoarding Disorder treatment group at the HH Anxiety Disorders Center

You may not qualify if:

• Not clinically appropriate for a group treatment format (i.e., active suicidality or aggressive behavior, psychosis, current physiological substance dependence, or personality issues that would be expected to substantially interfere with the group milieu; cognitively intact).
• Participants will also be excluded if they have previously completed CBT for HD.
• In addition, participants in the CM portion of the treatment will be required to live within one hour travel time of the treatment facility to allow for home visits with the independent rater.
