THE 5-FACTOR MODEL - QUO-VADIS

It is argued that research about the Five-Factor model has much to gai n from specification and analysis of middle-level categories that brid ge the distance between the broad-band Five-Factor level and the adjec tive or item revel. Two competing approaches, the AB5C-model and the N EO-PIR model, are discussed as viable but not necessarily incompatible approaches for further differentiation of the Five-Factor model. Anal ysis at the intermediate level of trait categorisation is considered t o be essential for charting the developmental roots of the Five-Factor model and to advance cross-language comparisons of trait structure.
