Evidence of the Cross-Cultural Stability of the Factor Structure of the SKT Short Test for Assessing Deficits of Memory and Attention

Abstract

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.

Psychomotor dysfunction after remifentanil/propofol anaesthesia

“…Originally the SKT was introduced in Germany; however, the test has been translated and validated in English and other languages [10,14,15]. It has been shown in neurological patients to mirror excellently the course of early and moderate severe dementia and to be sensitive to therapy in these stages.…”

The Bayer-Activities of Daily Living Scale (B-ADL): Results from a Validation Study in Three European Countries

“…To date, studies investigating the cross-cultural equivalence of assessment tools developed for the area of dementia have mainly been carried out with cognitive performance tests [14][15][16][17]. Only recently, in parallel with the increasing recognition of the need for a standardized assessment of patients' functional abilities in the diagnosis and monitoring of the progression of dementia, a series of scales measuring activities of daily living (ADL) have also been translated and evaluated with regard to their international applicability and validity [18][19][20].…”

Screening of cognitive impairment in the old and old-old population with the 3-CT scale

“…Кроме того, использована оригинальная шкала 3-КТ, которая представляет собой сочетание 3 ней-ропсихологических тестов: на зрительную память (запоминание 12 изображений из теста SKT [20], на речевую активность (семантически и фонетически опосредованные ассоциации за 1 мин) [21] и тест рисования часов [22]). Для оценки функционально-го статуса в условиях стационара использовали ори-гинальную шкалу (табл.…”
