  • 简介:当前的学习的PurposeThe目的是开发并且验证一项运动特定的谨慎措施,运动员谨慎问询表(AMQ),通过使用的5相关研究,4分开中国运动员的样品。AMQ是设计估计在运动context.MethodsIn研究1反映在场时刻的注意,了解,和接受的谨慎的一项3因素措施,项目的一个起始的水池基于以前的文学被产生,存在谨慎可伸缩,以及会见与并且从运动员,的反馈指导,并且谨慎专家。对AMQ的3因素结构的起始的支持经由探索因素被建立在学习2的分析,和通过在研究的确定的因素分析的跨validated3和4。在学习5,有直接措辞的接受项目的修改3因素AMQ在第四独立sample.ResultsConvergent被检验,接受subscale的并发的有效性没能在研究被证实3和4虽然解释颠倒措辞的项目,它可能由于运动员的疏忽和混乱。在5显示的令人满意的模型适合的学习和可接受的内部一致性的修改16条款AMQ。最重要地,16条款AMQ的会聚、并发的有效性被支持。3subscales与谨慎显示出重要积极协会,流动,健康,并且积极影响并且有经验的回避,染料烧尽,和否定affect.ConclusionTheAMQ的重要否定协会是在运动上下文的谨慎的一项psychometrically健全的措施。使用直接措辞的接受项目的重要性被讨论。
