: 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.: 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.: 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.: Anxiety, but not attentional bias, is elevated in concussion. Additionally, concussion and attentional bias to threat appear to be uniquely associated with anxiety symptoms.: Unique treatment/rehabilitation strategies should be considered for individuals with elevated anxiety following concussion.
: 脑震荡后的常见症状包括注意力处理缺陷和焦虑升高。优先将注意力资源分配给与威胁相关的信息被称为对威胁的注意力偏向，这是焦虑的一个主要症状——在某些情况下也是其发展的一个因果因素。在这里，我们旨在评估在与运动相关的脑震荡后阶段，注意力偏向与焦虑之间的关系的两种可能性：(1)注意力偏向在脑震荡和焦虑之间起中介作用；(2)注意力偏向和脑震荡与焦虑有独特的关联。
: 使用横断面组间设计来评估近期发生与运动相关的脑震荡的大学生运动员与匹配对照组之间的焦虑和对威胁的注意力偏向的差异。
: 42 名大学生运动员，21 名有与运动相关的脑震荡，21 名匹配的对照组，完成了注意力偏向的点探测任务和焦虑问卷。
: 脑震荡后焦虑升高，而注意力偏向则不然。此外，脑震荡和对威胁的注意力偏向似乎与焦虑症状有独特的关联。
: 对于脑震荡后焦虑升高的个体，应考虑采用独特的治疗/康复策略。
