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.
痴呆症研究中使用的许多心理测量工具都是在与应用这些工具的国家不同的国家开发的测试的改编版本。这些工具的有效性已在其原产国得到确立;然而,关于它们转移到其他文化中时的有效性,几乎没有可用信息。SKT是一种用于评估记忆和注意力缺陷的简短认知表现测试,在德国开发并验证,在智利、希腊、俄罗斯和英国的研究中心进行了施测。根据预先指定的目标结构对SKT原始分数进行因子分析,即针对一个大型德国参考样本找到的因子解。使用一种结合了完全一致权重法和自助法的统计方法评估该测试的跨文化稳定性。这个过程允许测试不同中心获得的因子解之间的相似性。结果清楚地表明了SKT在参与研究的国家中的因子稳定性。
