Abstract

Body-focused repetitive behaviors (BFRBs) are frequent but under-treated psychological disorders. The present study examined efficacy of three behavioral self-help techniques to reduce BFRBs: habit reversal training (HRT), decoupling (DC), and decoupling in sensu (DC-is). A total of 391 participants with BFRBs were randomly assigned to either HRT, DC, DC-is, or to a waitlist control group (WLC). After six weeks, a post assessment was conducted. The Generic Body-Focused Repetitive Behavior Scale-36 (GBS-36) served as the primary outcome. There were significant main effects for improvement in BFRB and depressive symptomatology over time, regardless of group assignment. For all GBS-36 scales, treatment groups showed greater improvement than WLC. DC and DC-is consistently showed greater improvements compared to WLC. According to moderator analyses individuals with more severe symptoms in the HRT and DC-is conditions benefited to a greater extent compared to WLC in terms of BFRB symptomatology. Also, individuals in DC condition with more severe depressive symptomatology showed a better outcome compared to HRT and WLC. Moreover, individuals with trichotillomania benefited more from DC or DC-is than from HRT. Subjective ratings of the techniques were satisfactory and comparable across groups, with DC-is receiving slightly lower subjective ratings. Future research should address the effects of the techniques when combined with psychotherapy. Also, long-term effects should be evaluated.

以身体为中心的重复性行为的自助:一项随机对照试验

以身体为中心的重复行为（BFRBs）是一种常见但治疗不足的心理障碍。本研究考察了三种行为自助技术减少BFRB的效果：习惯逆转训练（HRT）、脱钩（DC）和感官脱钩（DC-is）。共有391名患有BFRB的参与者被随机分配到HRT、DC、DC is或等待名单对照组（WLC）。六周后，进行了后评估。以一般身体为中心的重复行为量表-36（GBS-36）为主要结果。随着时间的推移，无论分组如何，BFRB和抑郁症状的改善都有显著的主要作用。在所有GBS-36量表中，治疗组的改善程度均高于WLC。DC和DC与WLC相比始终显示出更大的改进。根据主持人分析，在BFRB症状方面，与WLC相比，HRT和DC中症状更严重的个体在更大程度上受益。此外，与HRT和WLC相比，DC条件下抑郁症状更严重的个体表现出更好的结果。此外，拔毛癖患者从DC或DC比HRT受益更多。这些技术的主观评分令人满意，各组之间具有可比性，DC的主观评分略低。未来的研究应该解决这些技术与心理治疗相结合的效果。此外，还应评估长期影响。

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.
