Rational Emotive Behavior Therapy (REBT) is a cognitive-behavioral approach to counseling developed by Albert Ellis in the 1950s. It is based on the principle that emotional and behavioral problems are not caused directly by external events but by the beliefs individuals hold about those events. REBT aims to help people identify irrational beliefs, challenge them logically, and replace them with rational and constructive beliefs. This process enables clients to develop healthier emotions, effective coping strategies, and adaptive behaviors. The central assumption of REBT is that human beings have the capacity for both rational and irrational thinking. Irrational beliefs are rigid, illogical, and absolute in nature. They often involve demands such as "I must succeed," "Others must treat me fairly," or "Life must always be easy." When these unrealistic demands are not fulfilled, individuals experience unhealthy emotions such as severe anxiety, depression, guilt, anger, or shame. REBT helps clients recognize that these beliefs are self-defeating and contribute to emotional distress. A key concept of REBT is the ABC model. In this model, A stands for the activating event, B represents the individual's beliefs about the event, and C refers to the emotional and behavioral consequences. According to Ellis, it is not the activating event that causes emotional disturbance but the beliefs associated with it. Later, the model was expanded to include D, which stands for disputing irrational beliefs, E for developing effective new beliefs, and F for experiencing new feelings and behaviors. This expanded model provides a structured framework for therapeutic intervention. The counseling process in REBT begins with assessment and identification of the client's emotional difficulties and irrational beliefs. The counselor
