Objectives: Doping use is an ongoing concern in both competitive and recreational sports. The present study set out to investigate the effects of a self-affirmation intervention on the decision-making process relevant to doping among elite athletes who were doping users. Design A between subject experimental design was employed. Method: Sixty competitive athletes using doping substances took part in the study and were randomly assigned into active control and experimental groups. In the experimental group, participants received a self affirmation manipulation, whereas those in the active control group completed a neutral task. Subsequently, all participants were exposed to information relevant to the health side effects and moral aspects of doping use and subsequently completed a questionnaire about doping intentions and related social cognitions (i.e., attitudes, social and moral norms, self-efficacy beliefs, and anticipated regret). Results: Independent samples t-tests showed that self-affirmed participants reported significantly lower intentions to dope and temptation to engage in doping under risk-conducive situations. Multiple regression analysis showed that, whereas attitudes, moral norms and anticipated regret predicted doping use intentions, the effects of self-affirmation were not mediated by these social cognitive predictors of doping intentions. Conclusions: The study presents novel findings about the role of self-affirmation in the decision-making process relevant to doping use and can have direct implications for preventive interventions.
