Examining the effects rational emotive behaviour therapy (REBT) with embedded athlete rational resilience credo (ARRC) on the irrational beliefs, motivation regulation, and mental health of student-athletes

The use of rational emotive behavior therapy (REBT) in sport psychology is growing, and the use of the REBT-derived athlete rational resilience credo (ARRC) has been reported as an effective tool for use within REBT. The present study adds to the extant literature by examining the utility of REBT and the ARRC in reducing irrational beliefs, enhancing self-determined motivation, and mental health in three student-athletes. In a single-case design, student-athletes received REBT and were encouraged to produce their own ARRC. Visual analyses revealed that the ARRC in conjunction with REBT reduced irrational beliefs, improved self-determined motivation, and mental health in all three student-athletes. The current study supports and extends emerging REBT research by advancing the understanding of how REBT and the ARRC can be used to bolster self-determined motivation and mental health.
