Background: The purpose of this study was to examine the relationship between perceived coach-created empowering and disempowering motivational climate and doping likelihood among athletes and whether the attitudes towards doping and doping self-regulatory efficacy mediates these relationships. Methods: Athletes (N = 948; 50% male; mean age, 20.32, SD = 2.45) recruited from a variety of sports completed questionnaires assessing their perceptions of coach-created motivational climate, attitudes towards doping, doping self-regulatory efficacy, and doping likelihood. Results: The study's results showed significant negative direct effects of a perceived empowering climate on doping likelihood (beta = -0.50) and attitudes towards doping (beta = -0.48), and a positive effect on self-regulatory efficacy (beta = 0.48). On the contrary, a disempowering climate had positive direct effects on doping likelihood (beta = 0.53) and attitudes towards doping (beta = 0.45), and a negative effect on self-regulatory efficacy (beta = -0.49). Significant indirect effects on doping likelihood via attitudes and self-regulatory efficacy were found. Conclusions: Our findings suggest that athletes who perceive a more empowering climate created by the coach are less likely to use banned substances due to their more negative attitudes towards doping and stronger belief in their ability to resist the temptation to use doping.
