This study presents the initial item-level psychometrics of a functional cognition item bank, the FC-PRO, which shows adequate psychometric properties for evaluating specific functional cognitive domains in patients with traumatic brain injury (TBI).
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.
