Introduction: Defining and measuring limitations in functional status post-concussion has been challenging, as generic measures do not accurately reflect issues most relevant to adults with persistent post-concussion symptoms.

Purpose: To develop a new concussion-specific measure of functional status for use in clinical practice and intervention trials.

Method: We developed a conceptual model of functioning based on concepts identified from a previous qualitative study with persons with concussion and clinicians. An initial set of questionnaire items was generated from the concepts, codes, and conceptual model. Items were refined using cognitive interviews elicit feedback on their relevance and acceptability.

Results: We developed an initial set of 145 items categorized by concepts that were reduced to 50. Our final item set resulted in the COncussion REcovery Questionnaire, which contains a total of 53 items split into 3 separate scales: the Post-Concussion Functional Scale, Concussion Modifiers Scale, and Global Functional Recovery Scale.

Conclusion: The new Concussion Recovery Questionnaire is a self-reported measure of functional status for monitoring outcomes in clinical practice and in clinical intervention trials following concussion. Further studies are necessary to provide evidence of the measure’s psychometric properties and to determine the questionnaire’s ability to facilitate clinical decision-making.

简介：定义和测量脑震荡后功能状态的局限性具有挑战性，因为通用措施无法准确反映与持续存在脑震荡后症状的成年人最相关的问题。

目的：开发一种针对脑震荡的功能状态新指标，以用于临床实践和干预试验。

方法：我们根据先前与脑震荡患者和临床医生进行的定性研究确定的概念，开发了功能的概念模型。从概念，代码和概念模型中生成了最初的问卷项目集。使用认知访谈对项目进行细化，以获取有关其相关性和可接受性的反馈。

结果：我们根据概念将最初的145个项目分类为50个项目。最终的项目集产生了CO ncussion RE隐蔽问卷，其中包含53个项目，分为3个独立的量表：脑震荡后功能量表，脑震荡修饰语量表和全局功能恢复量表。

结论：新的脑震荡恢复问卷是一种自我报告的功能状态指标，用于监测脑震荡后的临床实践和临床干预试验的结果。有必要进行进一步的研究，以提供有关该措施的心理计量学特性的证据，并确定调查表促进临床决策的能力。
