Abstract

Background

Hoarding disorder causes significant impairment, but existing treatments have notable barriers to access and do not target several psychological processes that may contribute to hoarding. Therefore, this study evaluated an acceptance and commitment therapy (ACT) self-help website for hoarding with minimal coaching in a randomized waitlist-controlled trial to evaluate initial feasibility and efficacy.

Methods

Participants were 73 U.S.-based adults with clinically significant hoarding symptoms. The website comprised 16 self-help sessions to be completed over 8 weeks. Measures were taken at baseline, posttreatment, and 1-month follow-up.

Results

Multilevel models indicated that the ACT condition improved significantly more than waitlist on hoarding symptom severity (the primary outcome; β = 0.74, Holm-corrected p = .01) as well as secondary outcomes (e.g., functional impairment, well-being, and progress toward personal values, Holm-corrected ps < .05). Rates of reliable (34.61%) and clinically significant (11.54%) change at posttreatment were limited, with no significant differences between groups. Responses indicated that this intervention was acceptable, credible, and easy to use, although adherence could be further improved.

Conclusions

Overall, results suggest that an ACT self-help program for hoarding can be acceptable and efficacious. Limitations include a predominantly White and female sample and the lack of an active control condition.

腾出空间:一个接受和承诺囤积治疗网站的随机候补对照试验

囤积症会造成严重的损害，但现有的治疗方法有明显的障碍，并且没有针对可能导致囤积的几个心理过程。因此，本研究在一项随机候补对照试验中评估了一个接受和承诺治疗(ACT)自助网站，以评估囤积的初步可行性和有效性。方法研究对象为73名有明显囤积症状的美国成年人。该网站包括16个自助课程，需要在8周内完成。在基线、治疗后和1个月随访时采取措施。结果多水平模型显示ACT组在囤积症状严重程度(主要结局)上的改善显著高于等候组;β = 0.74，经holm校正的p = 0.01)以及次要结果(如功能障碍、幸福感和个人价值观的进展，经holm校正的ps <. 05)。治疗后的可靠变化率(34.61%)和临床显著变化率(11.54%)有限，两组间无显著差异。反应表明，这种干预是可接受的，可信的，易于使用，尽管依从性可以进一步提高。结论总体而言，本研究结果表明ACT自助治疗囤积症是可接受且有效的。局限性包括以白人和女性为主的样本和缺乏积极的控制条件。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
