Rational Emotive Behavior Therapy (REBT) is a comprehensive, active-irective, philosophically and empirically based psychotherapy which focuses on resolving emotional and behavioral problems and disturbances and enabling people to lead happier and more fulfilling lives. REBT was created and developed by the american psychotherapist and psychologist Albert Ellis who was inspired by many of the teachings of Asian, Greek, Roman and modern philosophers. REBT is one of the first and foremost forms of Cognitive Behavior Therapy (CBT) and was first expounded by Ellis in the mid-1950s.
