Rational Emotive Behaviour Therapy (REBT) and its relationship with self-determined motivation has received scant research attention despite growing interest in the motivational effects of REBT with athletes. Recent evidence suggests that reductions in irrational beliefs brought about by REBT may facilitate increases in self-determined motivation. The current study seeks to replicate and build this initial research using an idiographic single-case design to assess the effects of one-to-one REBT on the irrational beliefs, self-determined motivation, vitality, and sleep quality of four amateur triathletes. Self-report data were collected prior to, during, and after the REBT intervention. Visual analysis revealed that reductions in irrational beliefs were met with concomitant increases in self-determined motivation, vitality, and sleep quality. Social validation data supported the visual analysis findings. This current study supports and extends research by offering further advances in our understanding of the potential relationships between REBT, self-determined motivation, and athlete wellbeing.

使用理性情绪行为疗法 (REBT) 来增加铁人三项运动员的自决动机和心理健康。

尽管人们对 REBT 对运动员的激励作用越来越感兴趣，但理性情绪行为疗法 (REBT) 及其与自我决定动机的关系却很少受到研究的关注。最近的证据表明，REBT 带来的非理性信念的减少可能会促进自决动机的增加。目前的研究试图复制和构建这一初步研究，使用具体的单案例设计来评估一对一 REBT 对四名业余铁人三项运动员的非理性信念、自主动机、活力和睡眠质量的影响。在 REBT 干预之前、期间和之后收集了自我报告数据。视觉分析显示，非理性信念的减少伴随着自主动机、活力和睡眠质量的增加。社会验证数据支持视觉分析结果。目前的这项研究通过进一步推进我们对 REBT、自主动机和运动员幸福感之间潜在关系的理解来支持和扩展研究。关键词：CBT；辅导；运动; 精神健康; 案例分析
