Complexity of the self-concept was found to be associated with a self-report of identification with others, a topological measure of social interest, perception of persons older than the self as more similar to the self, and with greater popularity. It is concluded that the complexity of the self-concept is associated with acceptance of and by a wide variety of others. The initial framework is supported by the results. In terms of the self-concept, the control function associated with integration is assumed to be self-esteem. Self-esteem is linked to consistency of behavior across situations stemming from a supra-organization of the self-system. Thus the dual self components in Lewin's theory of differentiation integration. The construct of complexity has been explored in isolation only as the first stage in the approach to the more general framework described in this study. (Author)
