Exposure and Response Prevention (ERP) Training
ERP is the most extensively researched psychosocial treatment for OCD, with response rates reaching 60–80% when implemented correctly. Yet despite its established evidence base, well-trained ERP practitioners remain rare. Research shows that even clinicians trained in Cognitive Behavioral Therapy (CBT) frequently don't use exposure, or don't use it correctly. That scarcity means clients with OCD often wait years to find effective care.
PESI's ERP training changes that.
Whether you're new to exposure-based work or looking to sharpen your technique with the latest inhibitory learning research, PESI gives you the step-by-step skills to use ERP safely, confidently, and effectively, with OCD, panic disorder, agoraphobia, social anxiety, and the full spectrum of anxiety presentations.
ERP is the treatment of choice for:
- Obsessive-compulsive disorder (OCD) across all subtypes
- Panic disorder and agoraphobia
- Social anxiety disorder
- Specific phobias
- Illness anxiety disorder
- Body dysmorphic disorder
- Hoarding disorder
- OCD-related conditions, including Tics and Tourette's

Evidence-Based Mechanisms Behind the Method
How ERP Works: The Clinical Framework
ERP has two core components, and understanding the science behind each is what separates competent ERP delivery from truly effective ERP delivery.
Exposure means deliberately confronting the thoughts, images, objects, or situations that trigger a client's obsessions and anxiety. Exposures can be in vivo (real-world contact), imaginal (mental rehearsal), or interoceptive (confronting uncomfortable physical sensations). The clinician's job is to sequence these exposures strategically, building a graduated hierarchy that matches the client's fear ratings and moves progressively toward more challenging material.
Response Prevention means resisting the compulsive behavior or mental ritual the client would typically use to reduce distress. No washing. No checking. No reassurance-seeking. No mental neutralizing. This is the part that feels hardest for clients, and for some clinicians. But it is the mechanism through which lasting change occurs.
Why it works—inhibitory learning:
The earlier habituation model of ERP (anxiety goes up, then comes down through repeated exposure) has been refined by cutting-edge research into inhibitory learning. Under this updated framework, the goal isn't simply to reduce anxiety; it's to create new learning that inhibits the threat associations driving the OCD cycle. Clinicians trained in inhibitory learning principles know how to structure exposures to maximize expectancy violation, deepen extinction, minimize covert avoidance, and improve generalization after treatment ends.
This distinction matters clinically. ERP delivered without inhibitory learning principles can be less effective and harder for clients to sustain.
The exposure hierarchy: A well-constructed ERP hierarchy maps each client's specific triggers and compulsions, ranks them by distress level using a SUDS (Subjective Units of Distress Scale), and sequences exposure practice from lower-level to higher-level items. Building this hierarchy is a learned clinical skill and a core focus of PESI's ERP training.
