A Supplementary Approach for Effective Anti-Doping Education: A Pilot Study Applying Refutation Texts to Modify Misperception of the Whereabouts System

Background: Over the past twenty years, a multifaceted anti-doping system was established to detect, deter, and prevent doping among athletes. However, perception of the whereabouts system has been a controversial issue. This pilot study aimed to evaluate the effects of refutation text intervention on the perception of the whereabouts system. Methods: In two studies, we tested whether (1) detailed refutation texts are perceived as more effective than simply refuting with a true or false claim among 132 athletes (47.73% female, mean age = 20.99 ± 2.11), and if (2) refutation text intervention can alter the perception of the whereabouts system among 177 athletes (53.11% female, mean age = 21.17 ± 2.27). Descriptive statistics were calculated, followed by a one-sample T-test, independent T-test, chi-square test, and a repeated-measures analysis of variance. Results: The results demonstrate that five true/false statements were developed as refutation texts, and the mean accuracy of the true/false test is less than the probability of guess (p < 0.05, d = −0.18). In addition, detailed refutation texts evoked significantly greater perceived effectiveness than the simple refutation texts (p < 0.01, d = 0.66). Furthermore, the refutation text intervention enhanced the positive perception of the whereabouts system (p < 0.01, η(2) = 0.15). Conclusions: Our findings support the efficacy of refutation texts to improve the misperception of anti-doping regimes among athletes and have implications for future education prevention initiatives.
