Cognitive behavioural therapy (CBT) including exposure and response prevention is the first-line psychological treatment for obsessive compulsive disorder (OCD). Given changes in the clinical landscape, there are increasing efforts to evaluate its effectiveness in online contexts. Mirroring the traditional in-person delivery, few studies have assessed the role of therapist-guided, manual-based CBT for OCD delivered in real-time via videoconferencing methods. The present study sought to fill this gap by comparing in-person and online delivery of group-based CBT for the treatment of OCD. A convenience sample of participants with moderate to severe OCD (n = 144) were recruited from a naturalistic database from two large OCD specialty assessment and treatment centres. Patients received group-based CBT that was provided in-person (pre-COVID-19 pandemic; March 2018 to March 2020) or online via videoconferencing (during the COVID-19 pandemic; March 2020 to April 2021). In both delivery methods, treatment consisted of 2-h weekly sessions led by trained clinicians. Analyses revealed that, regardless of treatment modality, both in-person and online groups demonstrated significant, reliable, and statistically equivalent improvements in OCD symptoms post-treatment. Videoconferenced, clinician-led CBT may be a promising alternative to in-person delivery for those with moderate to severe OCD symptoms.

在线与面对面提供强迫症认知行为疗法：有效性检查

认知行为疗法（CBT）包括暴露和反应预防，是强迫症（OCD）的一线心理治疗。鉴于临床环境的变化，人们越来越多地努力评估其在在线环境中的有效性。与传统的面对面治疗一样，很少有研究评估治疗师指导的、基于手动的 CBT 通过视频会议方法实时治疗强迫症的作用。本研究试图通过比较面对面和在线提供的基于团体的 CBT 治疗强迫症的方法来填补这一空白。 从两个大型强迫症专业评估和治疗中心的自然数据库中招募了中度至重度强迫症参与者的方便样本（n = 144）。患者接受了面对面提供的基于团体的 CBT（COVID-19 大流行之前；2018 年 3 月至 2020 年 3 月）或通过视频会议在线提供（COVID-19 大流行期间；2020 年 3 月至 2021 年 4 月）。在这两种分娩方法中，治疗均包括由训练有素的临床医生主持的每周 2 小时的疗程。分析显示，无论采用何种治疗方式，现场治疗组和在线治疗组在治疗后强迫症症状均表现出显着、可靠且统计上相当的改善。对于那些患有中度至重度强迫症症状的人来说，视频会议、临床医生主导的 CBT 可能是面对面治疗的一种有希望的替代方案。
