摘要：Recently, a great attention has been devoted to stress. Thus, it is worth to have a simple and reliable tool measuring the current level of perceived stress. The aim of this paper is to present a validation of the Czech version of the Perceived Stress Scale which was developed by Cohen in 1983 and is a widely used instrument in this field. Verification of the questionnaire containing 10 items was carried out on a group of 358 university students. The statistical analysis included besides other things determination of the internal consistency and confirmatory factor analysis. The Czech version exhibited a high level of internal consistency with Cronbach´s alpha of 0.871. Confirmatory factor analysis revealed a two-factor structure preferred also in the literature and showed adequate values of both absolute and relative fit indices as well as indices of parsimony. The Czech version of the Perceived Stress Scale is valid and reliable instrument enabling measurement of perceived stress
