This study proposes to compare two forms of treatment for Hoarding Disorder (HD), a common and impairing neuropsychiatric syndrome that has a profound impact on the lives and functioning of individuals, families, and society. Specifically, we will compare a novel community-based group treatment led by individuals from the community who are not mental health professionals to the current standard of care treatment for Hoarding Disorder, cognitive behavioral therapy, conducted by psychologists in a group setting. We hypothesized that both treatment types will be similarly effective in reducing hoarding severity.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose treatment
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.
Sixteen sessions of peer-facilitated group support.
peer facilitated manualized support group
Sixteen 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.

Primary Outcomes

Saving Inventory-Revised (SI-R)
time frame: Administered at screening before start of treatment groups and after last treatment group (20 weeks later).

Secondary Outcomes

Neuropsychological Test Battery
time frame: Administered at screening before start of treatment groups and after last treatment group (20 weeks later).

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Diagnosis of Hoarding Disorder Exclusion Criteria: - Individuals with active psychosis, schizophrenia, intellectual disability, or known dementia will be excluded - Individuals who have participated in either cognitive-behavioral therapy for hoarding (group or individual) or in group Buried in Treasures in the past year

Description The study design for this proposal is a stratified, randomized, single-blind, non- inferiority trial comparing the current standard of care for treatment of Hoarding Disorder (HD), Group Cognitive Behavioral Therapy (G-CBT), to an innovative and promising community-based treatment, Group Buried in Treasures (G-BiT). Participants will be stratified by gender, psychiatric status (high vs. low burden of psychiatric symptoms) and insurance status (insured vs. under- or un-insured) so that equal numbers of individuals with each of these characteristics are randomized to each treatment arm. They will then be randomly assigned (randomized) to either G-CBT or G-BiT. Participants will know which treatment group they are assigned to, but those members of the research team who are conducting clinical or neuropsychological assessments or analyzing the data will not; they will be blinded to participant group assignment, and group leaders will be blinded to the psychiatric status, neurocognitive status, insurance status, etc, of participants. The study is a non-inferiority trial, that is, the hypothesis to be tested is that G-BiT is as effective, or no less effective, than G-CBT. We chose a non-inferiority design because we have no reason to believe G-BiT is better than G-CBT and our preliminary data, as well as outcomes previously reported for G- CBT and G-BiT, suggest that these treatments may have similar efficacies.
