Online cognitive assessment in the era of COVID-19: Examining the validity of the MEZURE.

Developed more than 2 decades ago, the MEZURE (Assessment Technologies, 1995-2020; https://www.mezure.com/) has received increased attention as a result of the COVID-19 pandemic. It is the first individualized test of cognitive ability created to use an online (local or remote) assessment modality. The MEZURE claims to be aligned both with the extended Gf-Gc theory and the Cattell-Horn-Carroll model of abilities. Whereas the test publisher claims it used exploratory factor analysis to investigate the instrument's factor structure, only the subtest factor loadings on the Gf-Gc factors were furnished. No other structural validity information was provided, suggesting that users of the instrument should interpret the scores produced by the MEZURE with caution. Accordingly, the present study used exploratory and confirmatory factor analysis to more fully investigate the structural validity of the MEZURE. The results revealed that the MEZURE contains a combined perceptual reasoning (i.e., [Gf/Gv]/working memory [Gwm]) group factor, a verbal ability group factor, and a relatively weak general factor that is dominated by perceptual reasoning. The finding of a paltry general factor that is weakly loaded by verbal subtests is inconsistent with the broader research on traditional cognitive ability assessment and could be related to the online administration format of the test. Future research is required to better understand this finding. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
