In 2 studies, college students evidenced differing levels of the Big-Five traits in different roles, supporting social-contextualist assumptions regarding trait expression. Supporting organismic theories of personality, within-subject variations in the Big Five were predictable from variations in the degree of psychological authenticity felt in different roles. In addition, two concepts of self-integrat ion or true selfhood were examined: 1 based on high consistency of trait profiles across roles (i.e., lowself-concept differentiation; E. M. Donahue, R. W. Robins, B. W. Roberts, & O. P. John, 1993) and 1 based on high mean levels of authenticity felt across roles. The 2 self-integration measures were found to be independent predictors of psychological and physical well-being indicating that both self-consistency and psychological authenticity are vital for organized functioning and health.
