Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 13 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-08-31
• Study Completion Date: 2014-10-31

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.

Detailed Description

The primary aim of the current study is a preliminary investigation of the efficacy of contingency management (CM) in the treatment of hoarding disorder (HD). CM is a highly efficacious treatment that has been used to treat issues such as substance use disorders, medication/ medical regimen nonadherence, and schizophrenia. While the current best-practice treatment for HD (cognitive behavioral therapy; CBT) is efficacious in that it results in significant symptom reduction, many patients continue to have high levels of functional impairment and distressing symptoms after treatment completion. We strongly feel that CM is able to address many of the issues that arise in the context of CBT for hoarding and we feel that the addition of CM to as CBT will result in significant pre- to post-treatment decreases in severity of hoarding symptoms and impairment, and significant increases in quality of life.

Study Groups

Contingency Management

Receives contingency payments each month based on decluttering scores

Group Type: EXPERIMENTAL

Contingency Management

Intervention Type: 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.

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

Exclusion Criteria

• 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.
