Drawing on the supplementary model of person-environment congruence (Muchinsky and Monahan, 1987), we employed aspects of the five-factor taxonomy of personality to test the effects of personality similarity on job satisfaction, job performance, and organization tenure in a structural model that also included psychological climate and role stress. Based on responses from 206 nursing service employees, we recovered five personality factors using similarity scores computed from the Adjective Check List (Cough and Heilbrun, 1965). Three of these factors (i.e., agreeableness, extraversion, conscientiousness) were included in an a priori, causal model using a subsample of 171 African Americans to demonstrate significant relations with job performance and organization tenure. The significant relations were incremental to the direct;effects of psychological climate and role stress on job satisfaction and to the causal influence of satisfaction on tenure.
