The Mindful Coach: A Pilot Study on the effectiveness of a MAC-Based Intervention, Incorporated with SDT Principles, Evaluated from the Athletes׳ Perspective

A pilot study was conducted to evaluate the indirect effectiveness of The Mindful Coach, a MAC-based intervention integrated with complementary SDT principles, designed for sport coaches, on their trainees. The intervention focused on enhancing coaches' intrapersonal and interpersonal skills, with the expectation of improving variables related to athletes’ well-being and performance.
Five sport coaches, responsible for instructing 55 athletes, participated in an 8-week
intervention consisting of weekly sessions, alongside a comparable control group of 51 athletes. Outcome measures, obtained through self-reported questionnaires from the athletes, focused on coach behaviors and athletes' self-competence, confidence, and sport-related anxiety.

本试点研究旨在评估专为体育教练设计的、整合了补充性自我决定理论（Self-Determination Theory，SDT）原则的基于MAC的干预方案——“正念教练（The Mindful Coach）”，对其受训运动员的间接干预效果。该干预方案聚焦于提升教练的内在自我调控能力与人际沟通技能，以期改善与运动员福祉及运动表现相关的各项变量。

共有5名负责指导55名运动员的体育教练参与了为期8周的干预项目，项目包含每周一次的授课环节；同期设置了规模匹配的对照组，包含51名运动员。本研究通过运动员提交的自我报告问卷收集效果评估指标，评估内容聚焦于教练行为，以及运动员的自我胜任感、自信心与运动相关焦虑。
