This short interview gives a quick outline of Rational Emotive Behavior Therapy (REBT): Albert Ellis: A Guide to Rational Living. FIML is not REBT and REBT is not FIML but the two methods are mutually supportive and probably not contradictory in all that many ways.
FIML resembles REBT in that it is a practice that can and will reduce neuroticism and unrealistic thinking. FIML is based on real data agreed upon by both partners and in this sense it is a pragmatic, scientific approach to human psychology and communication as is REBT.
FIML is different from REBT in that it is based on a specific technique that can be taught and then used by partners without the help of a therapist. FIML works primarily with very short segments of communication. It deals with belief, cognition, and emotion, but emphasizes accessing them by being attentive to the moment in a very concrete way.
FIML is not just psychotherapy but also very much a technique for anyone who wants to optimize communication with those who are most important to them. FIML helps partners understand how emotion, semiotics, habit, personal history, word associations, and so on influence how they listen and speak. FIML is largely value-neutral in what it says, though the practice will tend to strengthen awareness, rational thinking, and sound ethical behavior.
