The subject of the article refers to the problem of cross-cultural equivalence of test methods, appealing to the verbal self-report of respondents. This article is devoted to empirical comparison of the results and the application of the Kazakh-Russian-language versions of the research methods of value-meaning sphere of a person, namely, test of life orientations (by D.A.Leont’ev). The respondents were 60 undergraduates of Kazakh nationality, who performed the test in meaningfulness of life in two versions: the original in the Kazakh language, and a week later in Russian. It was found that the results of both versions (the Kazakh and Russian) are closely correlated with each other and have similar mean values. Consequently, they give equivalent results which allow us to use any variant of this method in research for respondents of Kazakh nationality.
