The article analyzes methodological and theoretical reasons for construction of multidimensional model of socialization of young people. The author assumes that the methodological treatment of the categories of activity, communication and self-awareness allow for adequate measurement of the process of becoming a social individual. On this basis he identifies theoretical resources of social, political, synergistic and cybernetic models of young people socialization, proving the acceptability of the process of their synthesis in the multivariate model.
