Objectives Sports coaches are influential in whether athletes dope, but receive very little antidoping education, particularly within entry-level coaching qualifications. We tested the feasibility of an antidoping intervention, delivered via a mobile application, which was designed to increase coaches’ knowledge of doping and to reduce favourable doping attitudes. Methods A two-arm randomised controlled trial, with grassroots coaches who coach young amateur athletes aged between 14 and 18 years of age, was conducted. The Anti-Doping Values in Coach Education (ADVICE) mobile application included modules on fair play, substances, nutritional supplements, rules and leadership. The primary outcome was the change in doping knowledge, 6 weeks after receiving the mobile application. The secondary outcome was changes in doping attitudes. Results Grassroots coaches (n=200; aged between 18 and 71 years, with between 1 and 42 years of coaching experience) from 29 different countries completed baseline assessments, and 85 completed follow-up assessments, and were included in mixed analysis of variance analyses. The intervention increased coaches’ knowledge about doping and also reduced favourable doping attitudes in the experimental arm. Conclusion The ADVICE mobile application is a feasible method for delivering and increasing grassroots coaches’ knowledge of banned substances and the potential side effects of doping. Mobile application-based resources could facilitate a much wider dissemination of antidoping education.

可行性随机对照试验，研究在教练教育（ADVICE）移动应用程序中反兴奋剂值对基层教练的兴奋剂知识和态度的影响

目标体育教练对运动员是否使用兴奋剂有影响，但很少接受反兴奋剂教育，尤其是在入门级教练资格范围内。我们测试了通过移动应用程序提供的反兴奋剂干预措施的可行性，该应用程序旨在增加教练对兴奋剂的知识并减少对兴奋剂的态度。方法进行了两臂随机对照试验，由基层教练指导14至18岁的年轻业余运动员进行。教练教育中的反兴奋剂价值（ADVICE）移动应用程序包括公平竞争，物质，营养补品，规则和领导力等模块。最初的结果是在收到移动应用程序后6周，兴奋剂知识发生了变化。次要结果是掺杂态度的改变。结果来自29个国家的基层教练（n = 200；年龄在18至71岁之间，具有1至42年的教练经验）完成了基准评估，并完成了85个后续评估，并纳入了方差分析的混合分析中。干预增加了教练对兴奋剂的了解，也降低了实验组对兴奋剂的态度。结论ADVICE移动应用程序是一种可行的方法，可用于传递和增加基层教练对违禁药物的了解以及掺杂的潜在副作用。基于移动应用程序的资源可以促进更广泛地传播反兴奋剂教育。完成了85项随访评估，并纳入了方差分析的混合分析中。干预增加了教练对兴奋剂的了解，也降低了实验组对兴奋剂的态度。结论ADVICE移动应用程序是一种可行的方法，可用于传递和增加基层教练对违禁药物的了解以及掺杂的潜在副作用。基于移动应用程序的资源可以促进更广泛地传播反兴奋剂教育。完成了85项随访评估，并纳入了方差分析的混合分析中。干预增加了教练对兴奋剂的了解，也降低了实验组对兴奋剂的态度。结论ADVICE移动应用程序是一种可行的方法，可用于传递和增加基层教练对违禁药物的了解以及掺杂的潜在副作用。基于移动应用程序的资源可以促进更广泛地传播反兴奋剂教育。结论ADVICE移动应用程序是一种可行的方法，可用于传递和增加基层教练对违禁药物的了解以及掺杂的潜在副作用。基于移动应用程序的资源可以促进更广泛地传播反兴奋剂教育。结论ADVICE移动应用程序是一种可行的方法，可用于传递和增加基层教练对违禁药物的了解以及掺杂的潜在副作用。基于移动应用程序的资源可以促进更广泛地传播反兴奋剂教育。
