Abstract: The Center for Epidemiologic Studies Depression Scale–Revised (CESD-R) has already been validated on the Polish population. However, the structure of the scale obtained at that time was not confirmed by confirmatory factor analysis (CFA) in subsequent studies on the Polish sample and measurement invariance for gender was not performed. The purpose of this article is to present the results of psychometric analyses to verify the structure of the CESD-R in a university student sample. An online cross-sectional study was conducted with 1519 university students (March/April 2021). The dataset was randomly divided into three subsets to perform principal component analysis (PCA, Subset 1) and CFA for CESD-R versions with different numbers of factors and items (Subsets 2 and 3). Measurement invariance for gender was verified for the whole sample. PCA pointed to a three-factor solution that was analyzed in the subsequent CFA. Due to high correlation coefficients between factors, further steps were taken using only one factor. For CFA, 20-, 18- and 9-item versions of the CESD-R were used, but the 9-item version obtained the best model fit parameters and was used to evaluate the measurement invariance for gender, which was confirmed. The 9-item CESD-R has the best model fit compared to other versions of this scale and is gender invariant. Further research is needed to verify the criterion validity of this shortened scale.
