Cognitive-behavioral treatment (CBT), including inference-based cognitive-behavioral therapy (I-CBT) for OCD and exposure with response prevention (ERP) for OCD and anxiety disorders such as panic disorder, agoraphobia, social anxiety disorder, body dysmorphic disorder (BDD), and chronic worry/generalized anxiety disorder (GAD). I also treat body-focused repetitive behaviors (BFRBs) such as hair pulling (trichotillomania) and skin picking (excoriation) disorders with a form of CBT called Comprehensive Behavioral treatment (ComB).
