The results confirm the four-factor structureof the Polish version of the CSES, support the wholePolish version of the CSES as well as its subscales, whichrepresent satisfactory reliability and stability, and provideinitial evidence of construct validity.ConclusionsAs the results of the study indicate, the Polish version ofthe CSES is a valid and reliable self-report measure for assessingthe global self-esteem derived from membership ofa group and has proved to be useful in the Polish context.
