Cognitive behavioral therapy (CBT) is the first choice of treatment of obsessive–compulsive disorder (OCD) in children and adolescents. However, there is often a lack of access to appropriate treatment close to the home of the patients. An internet-based CBT via videoconferencing could facilitate access to state-of-the-art treatment even in remote areas. The aim of this study was to investigate feasibility and acceptability of this telemedical approach. A total of nine children received 14 sessions of CBT. The first session took place face-to-face, the remaining 13 sessions via videoconference. OCD symptoms were recorded with a smartphone app and therapy materials were made accessible in a data cloud. We assessed diagnostic data before and after treatment and obtained measures to feasibility, treatment satisfaction and acceptability. Outcomes showed high acceptance and satisfaction on the part of patients with online treatment (89%) and that face-to-face therapy was not preferred over an internet-based approach (67%). The majority of patients and their parents classified the quality of treatment as high. They emphasized the usefulness of exposures with response prevention (E/RP) in triggering situations at home. The app itself was rated as easy to operate and useful. In addition to feasibility, a significant decrease in obsessive–compulsive symptoms was also achieved. Internet-based CBT for pediatric OCD is feasible and well received by the patients and their parents. Furthermore, obsessive–compulsive symptomatology decreased in all patients. The results of this study are encouraging and suggest the significance of further research regarding this technology-supported approach, with a specific focus on efficacy.

认知行为疗法（CBT）是儿童和青少年强迫症（OCD）的首选治疗方法。然而，患者家附近往往缺乏适当的治疗。通过视频会议的基于互联网的 CBT 可以促进获得最先进的治疗，即使在偏远地区也是如此。本研究的目的是调查这种远程医疗方法的可行性和可接受性。共有 9 名儿童接受了 14 节 CBT。第一次会议是面对面的，其余 13 次会议通过视频会议进行。使用智能手机应用程序记录强迫症症状，并在数据云中访问治疗材料。我们评估了治疗前后的诊断数据，并获得了可行性、治疗满意度和可接受性的衡量标准。结果显示，在线治疗患者的接受度和满意度很高 (89%)，面对面治疗并不优于基于互联网的方法 (67%)。大多数患者及其父母认为治疗质量很高。他们强调了暴露与反应预防 (E/RP) 在触发家庭情况方面的有用性。该应用程序本身被评为易于操作和有用。除了可行性之外，还实现了强迫症状的显着减少。基于互联网的儿童强迫症 CBT 是可行的，并受到患者及其父母的欢迎。此外，所有患者的强迫症症状均有所减少。这项研究的结果令人鼓舞，并表明对这种技术支持的方法进行进一步研究的重要性，
