Exploring the effects of Rational Emotive Behaviour Therapy (REBT) on the irrational beliefs and self-determined motivation of triathletes

The present study addresses proposals that Rational Emotive Behaviour Therapy
(REBT) can influence self-determined motivation. Triathletes received REBT
education, followed by either Rational Emotive Personal-Disclosure Mutual-Sharing
(REPDMS), or PDMS. Measurements of irrational beliefs and self-determined
motivation were collected prior to REBT (baseline), during the REBT education
period, and after the REPDMS session (post-intervention). An ABC single-case
design was adopted, allowing for statistical and visual analysis of data over time and
between groups. Findings indicate that REBT led to decreased irrational beliefs and
increased self-determined motivation. REPDMS appeared to have no influence on
irrational beliefs over and above REBT education.
