Kovalska Y. Validation of the use of the index of a person's social status in empirical sociological research in Ukraine

The dissertation is devoted to the modernization, adaptation and validation of the Warner Index Status Characteristics (ISС). The results of social structure research by Ukrainian researchers was considered. It has been established that in modern studies of social stratification in Ukraine, the indicator of the characteristics of a person’s real estate is little involved. It has been proposed to adapt and validate the Warner ISС, as a tool that includes not only the basic indicators of a person’s position in the system of social stratification, but also an indicator of the characteristics of real estate. Theoretically considered the types of validity and approaches to determining its level, as well as the level of reliability of tools; and the issues of reliability testing features in composite indexes. The level of theoretical (obvious and substantive) and empirical (criterion and constructive) validity of the Adapted Warner ISС was checked, the level of validity was determined as high. Formulated recommendations for measuring the reliability level of the Adapted Warner ISС. In the future, the Adapted Warner ISС can be used to study the stratification of modern Ukrainian society.
