Exposure and response prevention (ERP) therapy is a behavioral therapy that helps people learn to manage their response to feared situations and stimuli. It's often used to treat obsessive-compulsive disorder (OCD). 

Key aspects of ERP: 

• Gradual exposure: ERP gradually exposes people to situations that trigger their obsessions in a safe environment. 

• Confrontation: ERP encourages people to confront and accept their obsessions. 

• Response prevention: ERP helps people learn to refrain from their response to a feared stimulus. 

• Coping skills: ERP provides people with coping skills to prevent compulsions from taking over. 

• Trained clinician: A trained clinician works with the patient to develop an exposure plan and coach them through the process. 

• Hierarchy: A therapist can help build a hierarchy to keep the patient motivated. 

• Anxiety tolerance: ERP helps people learn to tolerate the anxiety that they feel, rather than avoiding it.
