Rational Emotive Behavior Therapy (REBT) is a form of cognitive-behavioral therapy developed by Albert Ellis in the 1950s. It focuses on identifying and changing irrational beliefs that lead to emotional distress and unhealthy behaviors. By challenging these beliefs, individuals can develop healthier thought patterns and improve their emotional well-being. In REBT, clients learn to recognize the connection between their thoughts, feelings, and actions. The therapy emphasizes the importance of self-acceptance and encourages individuals to replace negative beliefs with more rational ones. This process helps people cope with challenges and enhances their overall mental health.
