Many of the psychometric instruments employed in dementia research are adapted versions of tests developed in countries different from those in which they are applied. The validity of these instruments has been established in their countries of origin; however, there is little information available regarding their validity when transferred to other cultures. The SKT, a short cognitive performance test for the assessment of memory and attention deficits developed and validated in Germany, was administered in research centers in Chile, Greece, Russia, and England. SKT raw scores were factor analyzed with regard to a prespecified target structure, i.e., the factor solution found for a large German reference sample. The cross-cultural stability of the test was assessed using a statistical method that combined the perfect congruent weights approach and the bootstrapping technique. This procedure allowed for testing the similarity between factorial solutions obtained for the different centers. Results clearly indicate the factorial stability of the SKT in the countries participating in the study.
