REBT is a therapeutic approach that views people's irrational beliefs as the primary cause of emotional disturbances. It uses cognitive, emotional, and behavioral techniques to help clients identify and dispute their irrational beliefs and replace them with more rational and adaptive beliefs. The goal of REBT is not just to help clients feel better temporarily but to make profound philosophical changes that help them be less susceptible to future disturbances. Key techniques include identifying clients' core irrational beliefs, disputing those beliefs through different questioning methods, and helping clients develop rational coping statements.
