Abstract

Internet-delivered cognitive behavioural therapy (ICBT) is an effective treatment for obsessive-compulsive disorder (OCD). Currently there is limited research examining the predictors and moderators of outcome in ICBT for OCD. This study examined moderators of treatment outcome in a sample of 216 individuals who commenced a self-guided ICBT intervention for OCD (Mage = 34.00; SD = 12.57; 72.7% female). The results indicated that those with higher baseline OCD severity, depression severity, and neuroticism had less improvement at post-treatment and follow up (resulting in 40%, 24% and 12% higher symptom severity for every standard deviation increase on the measure at post-treatment and 33%, 17% and 20% higher symptoms at follow up respectively). However, participants with higher baseline treatment expectancy and readiness to reduce rituals and compulsions had better outcomes at post-treatment and three-month follow up (resulting in a 5% and 7% lower symptom severity for every standard deviation increase on the measure at post-treatment and 12% and 12% lower symptoms at follow up respectively). The results have important implications for who may respond best to self-guided ICBT.

自我指导的互联网认知行为疗法治疗强迫症效果的调节因素。

网络认知行为疗法（ICBT）是一种治疗强迫症（OCD）的有效方法。目前，对认知行为疗法治疗强迫症疗效的预测因素和调节因素的研究十分有限。本研究对216名强迫症患者（年龄=34.00；标准差=12.57；72.7%为女性）进行了自我指导的ICBT干预，并对治疗结果的调节因素进行了研究。结果表明，基线强迫症严重程度、抑郁严重程度和神经质程度较高的人在治疗后和随访中的改善程度较低（导致治疗后的测量值每增加一个标准差，症状严重程度分别增加 40%、24% 和 12%，随访中症状分别增加 33%、17% 和 20%）。然而，基线治疗期望值和减少仪式感和强迫症准备度较高的参与者在治疗后和三个月随访时的效果更好（治疗后测量值每增加一个标准差，症状严重程度分别降低 5% 和 7%，随访时症状分别降低 12% 和 12%）。这些结果对于哪些人最适合接受自我指导的综合心理治疗具有重要意义。

期刊介绍： The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
