Trial Outcomes & Findings for Comparison of Treatment for Hoarding Disorder (NCT NCT02040805)

NCT ID: NCT02040805

Last Updated: 2020-02-11

Results Overview

This is a 23-item self-report questionnaire that measures hoarding symptoms and their impact, including problems with acquisition, clutter, and difficulty discarding, as well as distress and impairment/interference. The SI-R is scored on a scale of 0-92. Higher scores indicate more severe hoarding, and scores of 42 and over are considered clinically significant hoarding. Although subscale scores can be calculated, this study uses total scores as the primary outcome.

Measure
Group Cognitive-Behavioral Therapy
Sixteen sessions of group therapy facilitated by a psychologist. Group Cognitive Behavioral Therapy: Group therapy over approximately 20 weeks, based on a structured manual adapted from the individual CBT workbook for hoarding by Steketee and Frost (2006). Each session will be 2 hours in length and consists of weekly check-ins, psychoeducation about hoarding, developing understanding and awareness of one's hoarding symptoms and patterns, behavior modification, cognitive restructuring, goal-setting, motivational enhancement, in vivo and imaginal exposure for discarding and acquisition, executive skills training (organization, sorting, planning, decision-making, problem-solving, etc.), guidelines on establishing "clutter buddies", and relapse prevention. Groups will be led by clinical postdoctoral psychology fellows in the Department of Psychiatry at UCSF.
Peer Facilitated Support Group
Fifteen sessions of peer-facilitated group support. Peer Facilitated Support Group: Fifteen sessions of peer facilitated, group support, over the course of 20 weeks, based on a structured manualized approach (Buried in Treasures: Help for Compulsive Acquiring, Saving, and Hoarding). Each session will be 2 hours in length. In this model, two trained peers, usually, but not necessarily, with personal lived experience of hoarding, will guide the group chapter by chapter through the Buried in Treasures manual.

SECONDARY outcome

Timeframe: Administered at baseline and after last treatment group (20 weeks later).

Population: All randomized participants who were not lost to follow-up.

The ADL-H is a 15-item self-report questionnaire that measures hoarding specific difficulties or problems that may impact daily functioning. It includes questions on activities affected by clutter or hoarding, problems in the home, and safety issues. For this study, the score on each ADL-H item was summed to create a total score ranging from 0 to 75. Higher scores indicate more severe functional impairment due to hoarding.

POST_HOC outcome

Timeframe: The post-hoc longitudinal data were collected at varying time points, but at least three months after the treatment ended. The range was 3 months to 25 months, with a mean of 14 months after treatment end.

Population: All randomized participants who were not lost to follow-up.

This is a 23-item self-report questionnaire that measures hoarding symptoms and their impact, including problems with acquisition, clutter, and difficulty discarding, as well as distress and impairment/interference. Using the SI-R, we obtained longitudinal follow-up data (defined as a second post-treatment assessment of hoarding symptom severity at least three months following completion of treatment). The total SI-R score was used, which ranges from 0-92, higher scores indicating more severe hoarding.
