Abstract Introduction This pilot study aims to explore the psychometric properties of Cognitive Function Instrument (CFI) as a measure subjective cognitive complaints (SCC) and its performance in distinguishing mild impairment (MCI) from normal control (NC) compared an objective screen (Montreal Assessment [MoCA]). Methods One hundred ninety‐four community‐dwelling non‐demented older adults with racial/ethnic diversity were included. Unidimensionality internal consistency CFI examined using factor analysis, Cronbach's alpha, McDonald's omega. Logistic regression models receiver operating characteristic (ROC) analysis used examine CFI. Results The demonstrated adequate consistency; however, fit for unidimensional model was suboptimal. distinguished MCI NC alone or combination MoCA. ROC showed comparable Discussion Our findings support use brief easy‐to‐use detect culturally/linguistically diverse adults. Highlight What is key scientific question problem central interest paper?
