The links of social–relational concepts (SRC) of personality identified in South Africa with the Five Factor Model (FFM), Interpersonal Relatedness (IR), social desirability, and prosocialness were examined. In Study 1 (N = 1483), the SRC defined two factors (positive and negative) distinct from the FFM, more strongly linked to relational than to tradition-focused IR aspects and to impression management than to deception. Links to tradition-focused concepts were stronger, and scores on positive SRC higher in Blacks than in Whites. In Study 2 (N = 325), SRC explained substantial variance in prosocialness above the FFM. In Study 3 (N = 1283), the SRC were replicated in a Dutch multicultural sample. The findings sug- gest expanding the FFM with respect to social–relational. functioning.
