Primary Objective: Symptoms following concussion commonly include deficits in attentional processing and elevated anxiety. Prioritized allocation of attentional resources to threat-related information is referred to as attentional bias to threat, which is a cardinal symptom - and in some cases a causal factor in the development - of anxiety. Here, we aimed to assess two possibilities regarding the relationship between attentional bias and anxiety in the post-concussive phase of sport-related concussion: (1) attentional bias mediates the relationship between concussion and anxiety or (2) attentional bias and concussion are uniquely associated with anxiety.Research Design: A cross-sectional between-groups design was used to assess differences in anxiety and attentional bias to threat between collegiate athletes with a recent sport-related concussion and a matched control group.Methods and Procedures: Forty-two collegiate athletes, 21 with a sport-related concussion and 21 matched controls, completed the dot-probe task of attentional bias and an anxiety questionnaire.Main Outcomes and Results: Anxiety, but not attentional bias, is elevated in concussion. Additionally, concussion and attentional bias to threat appear to be uniquely associated with anxiety symptoms.Conclusions: Unique treatment/rehabilitation strategies should be considered for individuals with elevated anxiety following concussion.

与运动相关的脑震荡与焦虑升高有关，但与对威胁的注意偏向无关。

主要目标：脑震荡后的症状通常包括注意力处理缺陷和焦虑加剧。对威胁相关信息的注意力资源的优先分配被称为对威胁的注意力偏差，这是焦虑的主要症状 - 在某些情况下是发展的因果因素。在这里，我们旨在评估关于运动相关脑震荡后脑震荡阶段注意偏向和焦虑之间关系的两种可能性：（1）注意偏向介导脑震荡和焦虑之间的关系或（2）注意偏向和脑震荡是唯一的与焦虑有关。研究设计：使用横断面组间设计来评估最近患有运动相关脑震荡的大学生运动员与匹配的对照组之间焦虑和注意力偏差的差异。 方法和程序：42 名大学生运动员，21 名参加运动相关脑震荡和 21 名匹配的对照，完成了注意偏向和焦虑问卷的点探针任务。主要结果和结果：焦虑，但不是注意偏向，在脑震荡中升高。此外，脑震荡和对威胁的注意力偏向似乎与焦虑症状唯一相关。结论：对于脑震荡后焦虑升高的个体，应考虑独特的治疗/康复策略。21 名患有运动相关脑震荡和 21 名匹配的对照组，完成了注意偏向和焦虑问卷的点探任务。主要结果和结果：焦虑，但不是注意偏向，在脑震荡中升高。此外，脑震荡和对威胁的注意力偏向似乎与焦虑症状唯一相关。结论：对于脑震荡后焦虑升高的个体，应考虑独特的治疗/康复策略。21 名患有运动相关脑震荡和 21 名匹配的对照组，完成了注意偏向和焦虑问卷的点探任务。主要结果和结果：焦虑，但不是注意偏向，在脑震荡中升高。此外，脑震荡和对威胁的注意力偏向似乎与焦虑症状唯一相关。结论：对于脑震荡后焦虑升高的个体，应考虑独特的治疗/康复策略。
