Introduction to Inference-Based CBT for OCD

Inference-Based CBT is an evidence-based treatment for OCD. Yet it is hardly being used in Aotearoa New Zealand. This one hour lecture will provide an introduction to I-CBT. If there is sufficient interest, it will be followed in 2026 with a full I-CBT workshop.

I-CBT is an upstream modality that targets the obsessional doubt of the OCD cycle. When the obsessional doubt is resolved, then the anxiety and compulsive aspects of OCD do not take place. I-CBT is completed through 12 modules. This training will give clinicians a brief overview of I-CBT, its mechanism of change, and its 12 modules.
