What We Treat Using ERP

Obsessive-Compulsive Disorder (OCD) is most effectively treated using Exposure and Response Prevention (ERP), a specialized form of Cognitive Behavioral Therapy. OCD involves intrusive thoughts, images, or urges (obsessions) that create anxiety, along with compulsions—such as checking, reassurance seeking, or mental reviewing—performed to reduce that distress.

In ERP, individuals learn that while intrusive thoughts are normal, the problem lies in how they respond to them. Compulsions may bring short-term relief, but they reinforce the cycle of OCD by teaching the brain that the thought was dangerous and required action.

Treatment involves gradually facing feared thoughts, images, or situations (exposure) while intentionally resisting compulsions (response prevention). For example, someone who fears leaving a door unlocked may practice leaving without checking. Over time, this helps reduce anxiety, build tolerance for uncertainty, and retrain the brain to see intrusive thoughts as less threatening.

Social Anxiety Disorder can be effectively treated using ERP, which focuses on reducing fear of social situations by breaking the cycle of avoidance and safety behaviors. This condition involves a strong fear of being judged, embarrassed, or negatively evaluated.

In ERP, individuals learn that behaviors like avoiding eye contact, over-rehearsing, or seeking reassurance may temporarily reduce anxiety but ultimately maintain it by preventing new learning.

Treatment involves gradually entering feared social situations (exposure) while dropping safety behaviors (response prevention). For example, someone might practice starting conversations without over-preparing or allow themselves to show signs of anxiety without trying to hide them. Over time, this helps disconfirm feared outcomes, reduce self-focused attention, and build confidence in social interactions.

As a result, they often avoid social interactions whenever possible. When faced with social situations they can’t avoid, they may experience physical symptoms like a racing heart, sweating, shaking, blushing, dizziness, or even full-blown panic attacks. Social anxiety can significantly interfere with everyday activities, including school, work, or maintaining relationships.

Perfectionism can be addressed using ERP by targeting rigid standards and the behaviors used to avoid mistakes or discomfort. Individuals with perfectionism often engage in excessive checking, over-preparing, procrastination, or avoidance to prevent imperfection.

In ERP, individuals learn that these behaviors maintain anxiety and reinforce the belief that mistakes are unacceptable or harmful.

Treatment involves intentionally creating situations where imperfection is possible (exposure) while resisting the urge to correct, check, or overcompensate (response prevention). For example, someone might submit work without excessive review or deliberately leave small errors uncorrected. Over time, this helps build tolerance for imperfection, reduce fear of mistakes, and develop more flexible standards.

Panic Disorder is effectively treated using ERP, particularly through interoceptive exposure, which targets fear of physical sensations. Panic attacks involve intense bodily symptoms that are often misinterpreted as dangerous.

In ERP, individuals learn that attempts to avoid or control these sensations—such as escaping situations or using safety behaviors—maintain the fear of panic.

Treatment involves deliberately bringing on feared physical sensations (exposure), such as increased heart rate or dizziness, while refraining from avoidance or safety behaviors (response prevention). Individuals may also enter situations they’ve been avoiding. Over time, this reduces fear of bodily sensations, breaks the cycle of panic, and restores confidence in one’s ability to cope.

When someone becomes overly focused on the possibility of experiencing future panic attacks and begins to fear them, they may be diagnosed with panic disorder. Many individuals with panic disorder also begin avoiding public or unfamiliar places where they fear having an attack and not being able to get help, this pattern of avoidance is referred to as agoraphobia.

Generalized Anxiety Disorder can be treated using ERP by targeting excessive worry and attempts to gain certainty. GAD involves persistent worry about everyday concerns, often driven by a low tolerance for uncertainty.

In ERP, individuals learn that behaviors like reassurance seeking, overthinking, or mentally reviewing scenarios function similarly to compulsions by temporarily reducing anxiety but reinforcing the need for certainty.

Treatment involves intentionally facing uncertainty (exposure) while resisting the urge to engage in worry or reassurance (response prevention). For example, someone might allow a worry to remain unresolved without analyzing it. Over time, this helps increase tolerance for uncertainty, reduce reliance on worry, and decrease overall anxiety.

Specific phobias are highly responsive to ERP, which focuses on reducing fear through direct, repeated exposure to the feared object or situation. Phobias involve intense, immediate anxiety and strong avoidance.

In ERP, individuals learn that avoidance keeps the fear strong by preventing the brain from learning that the situation is safe or manageable.

Treatment involves gradually and repeatedly confronting the feared stimulus (exposure) while refraining from escaping or using safety behaviors (response prevention). For example, someone with a fear of dogs might start by looking at pictures, then being near a dog, and eventually interacting with one. Over time, anxiety decreases, and the fear response weakens, allowing for greater freedom in daily life.

People with specific phobias will often go out of their way to avoid encountering their feared object or situation, even if it interferes with daily life, work, or relationships. Some commonly used terms for specific phobias include emetophobia (fear of vomiting), claustrophobia (fear of enclosed spaces), and trypophobia (aversion to clusters of holes or patterns).

Leslie Sommer was a trusted therapist for my daughter during her teenage years. She helped her achieve her goals and reflect on what kind of choices she wanted to be making with her life. Leslie supported her in navigating the ups and downs of evolving friendships, family tensions, and adolescence in general. My daughter looked forward to her appointments. I couldn't recommend her more.

She provided gentle and supportive care to our daughter, while also providing clear tools and methods for her to utilize on her own if going through a hard moment. Leslie would bring my husband and I in regularly to update us on how our daughter was doing and check in with us as well.

Questions About ERP Therapy

Yes. Exposure and Response Prevention (ERP) is the most effective, evidence-based treatment for OCD and many anxiety disorders. While these conditions may not fully “disappear,” ERP helps people gain control over their symptoms, significantly reduce distress, and return to living a full, meaningful life.

ERP works by helping you gradually face the thoughts, situations, or sensations you fear—without relying on avoidance or rituals. Over time, your brain learns that anxiety is tolerable and temporary, and that you don’t need compulsions or reassurance to feel okay. This leads to less anxiety and more freedom in your daily life.

Anxiety and OCD are driven by a combination of biological sensitivity, life experiences, and learned patterns of avoiding discomfort. These patterns keep anxiety going over time. ERP directly targets this cycle by helping you face fears and break habits like avoidance, checking, and reassurance seeking.

Anxiety and OCD aren’t simply problems of logic—they’re driven by how your brain responds to perceived threats. Trying to “think your way out” often makes anxiety worse. ERP focuses on changing your relationship with anxiety through action and experience, rather than trying to eliminate it through reasoning alone.

Many people begin to notice improvement within a few weeks of consistent ERP practice. Significant progress often occurs over a few months, depending on the severity of symptoms and level of engagement. ERP is most effective when practiced regularly both in and outside of sessions.
