A patient-reported functional cognition measure that can bridge neuropsychological tests and ecological validity is lacking. The purpose of this study was to present the initial item-level psychometrics of a functional cognition item bank, the Functional Cognition-Patient-Reported Outcome (FC-PRO). Confirmatory factor analysis, Rasch analysis, and convergent validity were conducted to establish item-level psychometrics of the FC-PRO item bank. Four of the six domains met essential unidimensionality criteria; all domains met rating scale criteria; domains had relatively few misfitting items (3%-13%); person reliability (.8-.92), and person strata (2.97-4.29) were satisfactory; the domains showed convergent validity for five of six domains. The FC-PRO showed adequate initial item-level psychometrics for researchers/clinicians to measure specific functional cognitive domains in patients with traumatic brain injury (TBI). This study provides the foundation for the development of future short forms, computer adaptive tests, and keyform recovery maps of patient-reported functional cognition to facilitate clinical utilization.
目前缺乏一种能够连接神经心理学测试和生态有效性的患者报告的功能性认知测量方法。本研究的目的是介绍功能性认知-患者报告结果（FC-PRO）功能性认知项目库的初步项目水平心理测量学。为了建立 FC-PRO 项目库的项目水平心理测量学，进行了验证性因素分析、Rasch 分析和收敛效度分析。六个领域中的四个领域符合基本的单维性标准；所有领域都符合评分量表标准；领域中只有少数不适合的项目（3%-13%）；个人可靠性（.8-.92）和个人层次（2.97-4.29）令人满意；五个领域中的六个领域显示出收敛效度。FC-PRO 为研究人员/临床医生在创伤性脑损伤（TBI）患者中测量特定的功能性认知领域提供了足够的初始项目水平心理测量学基础。这项研究为未来的短形式、计算机自适应测试和患者报告的功能性认知关键表单恢复图的发展提供了基础，以促进临床应用。
