@article { , title = {The Effects of the iPlayClean Education Programme on Doping Attitudes and Susceptibility to use Banned Substances among High-Level Adolescent Athletes from the UK: A Cluster-Randomised Control Trial}, abstract = {Background: This study examined the effects of the iPlayClean anti-doping intervention on attitudes towards doping and susceptibility, and whether delivery mode affected the results. Methods: A total of 1,081 high-level UK athletes (14-18 years old, 904 males, 177 females) were cluster-randomised to the control (11 teams/organisations/schools, 314 athletes), face-to-face group presentation (8 teams/organisations/schools, 254 athletes), online (11 teams/organisations/schools, 251 athletes), or face-to-face presentation with online access (5 teams/organisations/schools, 262 athletes). Results: Compared to the control group, all modes of the iPlayClean anti-doping education programme reduced favourable attitudes towards doping immediately after the intervention, which was sustained across all intervention groups 8 weeks later. All delivery modes impacted doping susceptibility immediately after the intervention, in comparison to the control group, but the effects were only sustained for the face-to-face presentation group. Conclusion: Contrary to findings within previous anti-doping interventions, we have shown that doping attitudes can be changed and that the results can be sustained across all modes of delivery, 8 weeks later. Research is required to assess for how long these changes are sustained, and how often anti-doping education should be delivered to high-level athletes to reinforce clean play values.}, issn = {0955-3959}, journal = {International Journal of Drug Policy}, publicationstatus = {Accepted}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/3515796}, keyword = {Health and Health Inequalities}, author = {Nicholls, Adam and Morley, David and Thompson, Mark A. and Huang, Chao and Abt, Grant and Rothwell, Martyn and Cope, Edward and Ntoumanis, Nikos} }
