Web-based Acceptance and Commitment Therapy for Hoarding Disorder

Utah State University80 enrolled

Overview

This study will help to determine if acceptance and commitment therapy delivered as a web-based intervention is a useful treatment for hoarding disorder and evaluate whether or not web-based treatment for hoarding is credible and acceptable. It may also help identify novel processes of change in hoarding treatment such as psychological inflexibility, mindfulness, and self-stigma.

The efficacy of an ACT self-help website for hoarding will be assessed through a randomized, waitlist-controlled trial. Participants will be recruited from within the United States through a variety of channels. Given the need to recruit a targeted sample with clinical levels of hoarding symptoms, online advertisements through Facebook and Google AdWords will be the primary recruitment method. Participants will complete an initial brief screening, provide consent, and then complete a baseline survey. Each of these steps will be completed online and participants will be automatically guided from each step to the next. That is, those who screen as eligible will be automatically directed to an online consent form, and those who provide consent will be automatically directed to begin the initial online baseline survey. They will be randomly assigned automatically upon completing the baseline survey to either use the ACT self-help website and receive supportive coaching for the next 8 weeks, or wait for the next 8 weeks. After 8 weeks, participants will be asked to complete a posttreatment survey. They will be asked to complete a final, follow-up survey after an additional 4 weeks after the posttreatment survey. After the follow-up survey is completed, waitlisted participants will be provided with access to the website. The website will implement a self-help version of ACT. Participants will be asked to complete 16 brief self-help website sessions, each taking around 15-20 minutes to finish, twice a week for eight weeks. Participants assigned to the website condition will also receive coaching.The purpose of coaching will be to help participants engage with the website and adhere to the intervention. Coaching will consist of an initial phone call of 10-15 minutes followed by weekly email contact during the 8-week treatment period. Coaches will be graduate students trained in clinical psychology.

Outcomes

Primary Outcomes

Saving Inventory-Revised (SI-R; Frost et al., 2004)

A self-report measure of hoarding symptoms

Time frame: Posttreatment (8 weeks after baseline)

Secondary Outcomes

Sheehan Disability Scale (Sheehan, Harnett-Sheehan, & Raj, 1996)

A self-report measure of functional impairment due to symptoms. Higher scores indicate greater impairment. Scores range from 0 to 30.

Time frame: Posttreatment (8 weeks after baseline) and follow-up (12 weeks after baseline)

Clinical Global Impression - Improvement (CGI-I; Guy, 1976).

A self-report measure of overall improvement in symptoms

Time frame: Posttreatment (8 weeks after baseline) and follow-up (12 weeks after baseline)

General Health Questionnaire-12 (GHQ-12; Goldberg, 1978)

A self-report measure of overall psychological distress

Time frame: Posttreatment (8 weeks after baseline) and follow-up (12 weeks after baseline)

Stigma of hoarding items (Chasson et al., 2018)

Seven self-report items assessing stigma towards individuals with hoarding disorder. These items are not a standardized scale but have been used in previous research (Chasson et al., 2018). Three items assess perceived difference (Example: How like or unlike do you think is a person with obsessive-compulsive disorder compared to everyone else in the general population?), three items assess disdain (Example: How good or bad do you think is a person with hoarding disorder compared to everyone else in the general population?) and one item assesses blame: How responsible do you think a person with serious mental illness is for his or her condition?

Time frame: Posttreatment (8 weeks after baseline) and follow-up (12 weeks after baseline)
