Using Rational Emotive Behavior Therapy (REBT) with Mixed Martial Arts (MMA) Athletes to Reduce Irrational Beliefs and Increase Unconditional Self-Acceptance

© 2016, Springer Science+Business Media New York. The reported application of rational emotive behavior therapy (REBT) with athletes is growing but remains scarce within sport psychology literature. This study used a single-case multiple-baseline across participants design to investigate the effects of REBT on irrational self-depreciation beliefs and unconditional self-acceptance (USA) with three male mixed martial arts (MMA) athletes. Visual and statistical analyses indicate a reduction in total irrationality and self-depreciation and an increase in USA, which was maintained at 6 months post-REBT for two of the three athletes. Social validation data revealed positive changes in emotion management and performance in all athletes. The mechanisms by which REBT promoted changes in self-depreciation and USA are discussed as are recommendations regarding the future implementation of REBT with athletes
