Abstract

Cognitive-behavioral therapy including exposure and response prevention is the first-line treatment of pediatric OCD showing response- and remission rates around 70% and 53%. Thus, there is room for improvements. Metacognitive therapy (MCT) for OCD might be cost-effective and focuses on modifying metacognitive beliefs about the significance and dangerousness of intrusive thoughts/feelings, and about the need to perform rituals. MCT is effective in adults but needs to be evaluated in youths. In the current study, eleven adolescents divided in three groups received eight MCT group sessions of 75 min duration (and two 60 min workshop for parents) delivered by an MCT-therapist and an assistant. The within-group effect size (hedges g) from pre-to post-treatment on the CY-BOCS was 1.90, and the response and remission rates were 82% and 55%, respectively. Effect sizes for secondary outcomes were also large. Therapist time (one certified MCT-therapist and a clinical psychology student working together) used per patient to achieve these results were 2.18 therapy sessions of 75-min duration in addition to 33 min therapist time per patient of workshops for the parents. Follow-up assessments were not available, and the results should be interpreted with caution. However, they are encouraging and suggest that MCT for pediatric OCD should be evaluated further.

治疗小儿强迫症的团体元认知疗法：试点研究

包括暴露和反应预防在内的认知行为疗法是治疗小儿强迫症的一线疗法，其反应率和缓解率分别约为 70% 和 53%。因此，仍有改进的余地。强迫症的元认知疗法（MCT）可能具有成本效益，其重点是改变对侵入性想法/感觉的重要性和危险性以及对仪式需要的元认知信念。MCT对成年人有效，但对青少年还需要进行评估。在本次研究中，11 名青少年被分为三组，接受了由一名 MCT 治疗师和一名助理主持的八次 75 分钟的 MCT 小组课程（以及两次 60 分钟的家长工作坊）。从治疗前到治疗后，CY-BOCS的组内效应大小（对冲克）为1.90，反应率和缓解率分别为82%和55%。次要结果的效应大小也很大。为取得这些结果，治疗师（一名获得认证的 MCT 治疗师和一名临床心理学学生合作）为每位患者花费了 2.18 次治疗，每次 75 分钟，此外，治疗师还为每位患者花费了 33 分钟为家长举办研讨会。由于没有进行后续评估，因此在解释结果时应谨慎。不过，这些结果令人鼓舞，并建议进一步评估 MCT 治疗小儿强迫症的效果。

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.
