This paper summarizes the state of empirical research on the five-fact
or model (FFM). The basic assumptions of the lexical approach to perso
nality psychology are presented, and the historical roots of the ,,Big
Five'' are traced. The results of several taxonomies indicate that th
e FFM provides a robust description of personality that - similar to O
sgood's dimensions of affective meaning - proves to be highly replicab
le. Relations between the five factors and the dimensions of alternati
ve models of personality structure are considered, and the conceptual
status of the Big Five is discussed.
