Very little research has been done so far on the psychological determinants of performance-enhancing substance use in sports. The purpose of this study was to propose and test a motivational model of performance-enhancing substance use with elite athletes (N = 1,201). The model posits that intrinsic and extrinsic motivation toward sport predict, respectively, positive and negative sportspersonship orientations, which in turn negatively predict the use of performance-enhancing substances. Participants completed a questionnaire assessing intrinsic and extrinsic motivation toward sport, sportspersonship orientations, and performance-enhancing substance use in the last 12 months. Findings supported the motivational model. The present findings support the role of intrinsic motivation and sportspersonship orientations in preventing athletes from engaging in unethical behavior such as the use of performance-enhancing substances. Future research should seek to replicate this model with professional and Olympic athletes.

Vallerand et al. (2003) developed a dualistic model of passion, wherein two types of passion are proposed: harmonious (HP) and obsessive (OP) passion that predict adaptive and less adaptive interpersonal outcomes, respectively. In the present research, we were interested in understanding the role of passion in the quality of coach–athlete relationships. Results of Study 1, conducted with athletes (N = 157), revealed that HP positively predicts a high-quality coach–athlete relationship, whereas OP was largely unrelated to such relationships. Study 2 was conducted with coaches (N = 106) and showed that only HP positively predicted the quality of the coach–athlete relationship. Furthermore, these effects were fully mediated by positive emotions. Finally, the quality of the coach–athlete relationship positively predicted coaches’ subjective well-being. Future research directions are discussed in light of the dualistic model of passion.
