ABSTRACT A conceptual hierarchy termed the Personality and Role Identity Structural Model, or PRISM, is offered as a framework for incorporating situational information into trait models. PRISM assumes that personality is structured hierarchically with general dispositions subsuming context-specific dispositions (role identities), which, in turn, subsume role-based thoughts, feelings, and behaviors. At Wave 1 (N=149), we found that general traits account for commonalities across traits measured within role identities and that role identities mediate the relationship between general traits and role criteria. In a longitudinal follow-up of a subsample of the original participants (Wave 2; N=62), we found that general traits and role-identity traits were more stable than role experiences over time. Also, changes in role experiences were related to changes in role-identity traits, and, in turn, changes in role-identity traits were related to changes in general traits. The potential of PRISM for use in understanding the development of personality traits is discussed.
