Exposure and Response Prevention (ERP)

ERP is a specialized form of cognitive-behavioral therapy that gradually exposes clients to feared thoughts or situations while helping them resist the urge to perform compulsions — breaking the OCD cycle at its core.

Exposure and Response Prevention (ERP) is the gold-standard, evidence-based treatment for OCD. It works by gradually and systematically exposing clients to situations that trigger obsessive thoughts, while guiding them to refrain from compulsive responses. Over time, this breaks the anxiety-compulsion cycle and builds lasting tolerance.

Shannon Tarolli and Jen Meehan both specialize in ERP at Clarity Counseling of Delaware, bringing compassionate, structured support to clients who have often felt trapped by their OCD for years.

How It Works

The Exposure and Response Prevention process

  1. 1

    Assessment & Hierarchy Building

    Collaboratively mapping out your specific triggers, obsessions, and compulsions to build a structured exposure hierarchy — ordered from least to most distressing.

  2. 2

    Psychoeducation

    Understanding how OCD works, why compulsions provide only temporary relief, and how ERP interrupts the cycle.

  3. 3

    Graduated Exposure

    Working through the exposure hierarchy at a pace that challenges you without overwhelming. Each step builds confidence for the next.

  4. 4

    Response Prevention

    Learning to sit with anxiety and uncertainty without performing compulsions — developing the tolerance that breaks the OCD loop.

  5. 5

    Maintenance & Relapse Prevention

    Building a long-term plan to maintain gains and handle future flare-ups with confidence.
