Systematic exposure and response prevention

Exposure therapy is a type of behavioural therapy that is designed to help people manage problematic fears. Through the use of various systematic techniques, a person is gradually exposed to the situation that causes them distress, without engaging in associated rituals or avoidance (i.e., response prevention). The goal of exposure therapy is to create a safe environment in which a person can reduce anxiety, decrease avoidance of dreaded situations, and improve one's quality of life.
