Abstract

Background

People affected by skin picking disorder (SPD) feel a strong urge to manipulate their skin and feel incapable of stopping. First studies on cognitive-behavioral treatments found moderate to large effects on the reduction of symptomatology. We developed an easy to access cognitive-behavioral self-help program and tested its efficacy on SPD.

Method

The program includes modules on self-awareness, psychoeducation, strategies to control picking and relapse-prevention. In a multiple baseline-design 43 women diagnosed with SPD accessed the online program. Symptomatology was assessed via skin picking scales before, throughout, and after the completion of the intervention. We analyzed the data using a repeated measurement ANOVA and planned contrasts.

Results

We found significant large effects for skin picking symptom reduction throughout a 6-month follow-up (0.325 ≤ η_p² ≤ 0.430) for completers (n = 25). In planned contrasts the significant reduction of symptoms (after baseline self-monitoring) to 6-month follow-up was large (0.281 ≤ η_p² ≤ 0.375).

Conclusions

With the internet-based self-help program Knibbelstopp we implemented an efficacious self-help tool for SPD, which requires further investigation regarding generalizability of this effect. Our self-help program is accessible online and may help to improve the health care situation for German speaking individuals with SPD.

基于互联网的自助项目治疗多基线设计抠皮障碍的疗效:一项试点研究

背景受皮肤选择障碍（SPD）影响的人有强烈的皮肤操作冲动，感觉无法停止。首次对认知行为治疗的研究发现，对症状的减轻有中度到重度的影响。我们开发了一个易于访问的认知行为自助程序，并在SPD上测试了其效果。方法该程序包括自我意识、心理教育、控制选择策略和复发预防模块。在一项多基线设计中，43名被诊断为SPD的女性访问了该在线程序。在干预前、干预期间和干预完成后，通过皮肤采集量表评估症状。我们使用重复测量方差分析和计划对比分析数据。结果我们发现，在6个月的随访中，完成者（n=25）的皮肤挑刺症状减轻效果显著（0.325≤ηp2≤0.430）。在有计划的对比中，症状（基线自我监测后）到6个月随访的显著减少很大（0.281≤ηp2≤0.375）。结论通过基于互联网的自助计划Knibbelstopp，我们为SPD实施了一种有效的自助工具，这需要进一步调查这种效果的普遍性。我们的自助计划可以在线访问，可能有助于改善德语SPD患者的医疗保健状况。

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.
