Background:The impacts of COVID-19 for people with obsessive-compulsive disorder (OCD) may be considerable. Online cognitive behavioural therapy (iCBT) programmes provide scalable access to psychological interventions, although the effectiveness of iCBT for OCD during COVID-19 has not been evaluated.Aim:This study investigated the uptake and effectiveness of iCBT for OCD (both self- and clinician-guided courses) during the first 8 months of the pandemic in Australia (March to October 2020) and compared outcomes with the previous year.Method:1,343 adults (824/1343 (61.4%) female, mean age 33.54 years, SD = 12.00) commenced iCBT for OCD (1061 during the pandemic and 282 in the year before) and completed measures of OCD (Dimensional Obsessive-Compulsive Scale) and depression (Patient Health Questionaire-9) symptom severity, psychological distress (Kessler-10), and disability (WHO Disability Assessment Schedule) pre- and post-treatment.Results:During COVID-19, there was a 522% increase in monthly course registrations compared with the previous year, with peak uptake observed between April and June 2020 (a 1191% increase compared with April to June 2019). OCD and depression symptom severity were similar for the COVID and pre-COVID groups, although COVID-19 participants were more likely to enrol in self-guided courses (versus clinician-guided). In both pre- and during-COVID groups, the OCD iCBT course was associated with medium effect size reductions in OCD (g = 0.65–0.68) and depression symptom severity (g = 0.56–0.65), medium to large reductions in psychological distress (g = 0.77–0.83) and small reductions in disability (g = 0.35–.50).Conclusion:Results demonstrate the considerable uptake of online psychological services for those experiencing symptoms of OCD during COVID-19 and highlight the scalability of effective digital mental health services.

基于互联网的认知行为疗法对强迫症症状的吸收和效果与 COVID-19 相关的差异

背景：COVID-19 对强迫症 (OCD) 患者的影响可能相当大。在线认知行为疗法 (iCBT) 计划提供了可扩展的心理干预途径，尽管尚未评估 iCBT 在 COVID-19 期间对强迫症的有效性。目的：本研究调查了 iCBT 对强迫症（自我和临床医生）的吸收和有效性- 指导课程）在澳大利亚大流行的前 8 个月（2020 年 3 月至 2020 年 10 月），并将结果与​​上一年进行比较。方法：1,343 名成年人（824/1343（61.4%）女性，平均年龄 33.54 岁，标清= 12.00）开始针对强迫症的 iCBT（大流行期间为 1061 人，前一年为 282 人）并完成了强迫症（维度强迫症量表）和抑郁症（患者健康问卷 9）症状严重程度、心理困扰（Kessler-10）的测量，以及残疾（WHO 残疾评估表）治疗前后。结果：在 COVID-19 期间，与上一年相比，每月课程注册增加了 522%，在 2020 年 4 月至 2020 年 6 月期间观察到峰值吸收（a与 2019 年 4 月至 2019 年 6 月相比增加了 1191%）。尽管 COVID-19 参与者更有可能参加自学课程（相对于临床医生指导），但 COVID 和 COVID 前组的强迫症和抑郁症状严重程度相似。在 COVID 之前和期间的组中，G= 0.65–0.68) 和抑郁症状严重程度 (G= 0.56–0.65），心理困扰的中到大减少（G= 0.77–0.83）和残疾的小幅减少（G= 0.35–.50)。结论：结果表明，在 COVID-19 期间出现强迫症症状的人大量使用在线心理服务，并突出了有效数字心理健康服务的可扩展性。
