ABSTRACT

This case study offers a unique insight into the application of a one-to-one REBT programme on the self-regulation of performance strategies and behaviors of a 17-year-old nationally ranked male tennis player. A needs analysis highlighted feelings of heightened anxiety prior to, and during, matches against players who were similarly ranked, coupled with a pre-occupation as to how his performance was viewed by significant others. This anxiety was exacerbated by a self-imposed deadline that involved gaining ATP (Association of Tennis Professionals) ranked status within a year’s time. The client was harbouring irrational beliefs concerning success that were having debilitating effects upon his ability to perform. Trait measures of irrational beliefs were taken on a session-by-session basis, whilst self-efficacy and perceptions of control of tennis specific performance markers were taken on a match-by-match basis. Additionally, semi-structured interviews were collected at pre-, middle-, and post-intervention exploring the self-regulatory behaviors of the client. Data revealed meaningful short- and long-term reductions in irrational beliefs, in conjunction with increases in self-efficacy and perception of control. Over the course of the intervention, self-regulatory behaviors changed from being maladaptive to adaptive in the attainment of performance goals. Social validation data further supported the effectiveness of REBT as an intervention to develop athletic performance.
