Translating CBT for OCD into Practice: Modalities, Effectiveness, and Implementation

Dear Colleagues,

Cognitive Behavioral Therapy (CBT) is the first-line treatment for Obsessive–Compulsive Disorder (OCD), with strong evidence supporting its efficacy through standard 10–12 week protocols. However, its real-world effectiveness remains a challenge, particularly when considering accessibility, intensity, and healthcare system constraints. CBT delivery has diversified in recent years. Low-intensity formats—such as digital programs, reduced-frequency sessions, and varied providers (e.g., graduate students)—have enhanced access in programs like the UK's IAPT and Australia’s MindSpot. In Japan, adaptations include reducing session frequency to once or twice per month to ease patient burden while maintaining core components. Conversely, high-intensity CBT (e.g., twice-weekly sessions or inpatient care) is essential for severe or comorbid cases. As systems move toward stepped care, evaluating the effectiveness and clinical utility of each modality becomes increasingly important. This Special Issue invites original research and reviews on the delivery, scalability, and cost-effectiveness of CBT for OCD. We welcome studies on intensity variation, digital tools, therapist-level factors, and implementation models. In addition to assessing each modality’s effectiveness, we seek contributions that explore how interventions can be selected, prioritized, or integrated within healthcare systems—whether through algorithms, adaptable pathways, or comprehensive frameworks.
