Hierarchical classification and the integration of self-structure in late adolescence.

A number of empirical studies have demonstrated that one's self-concept is multi-dimensional in nature, varies according to social context, and shows increased differentiation throughout adolescence. There has been relatively less work, however, examining the integration of multi-dimensional social selves. Rosenberg and Gara's (1985) model of the multidimensional self (a model that utilizes a statistical procedure called "hierarchical classification" or HICLAS) was employed to investigate the integration of social selves during late adolescence. First- and fourth-year college students (n=128) completed a computer program designed to collect data required to construct HICLAS "self-structures". The findings indicated that the social selves of fourth-year college students were more related conceptually and were more differentiated than the social selves of first-year students. The differences between first- and fourth-year students suggested that hierarchical classification procedures could be used to address developmental hypotheses.
