COMPARISON OF FACTOR STRUCTURES AND CRITERION-RELATED VALIDITY COEFFICIENTS FOR 2 MEASURES OF PERSONALITY BASED ON THE 5-FACTOR MODEL

The factor structure and criterion-related validity for 2 types of per sonality measures that are based on 5 factor models were studied. Conf irmatory factor analysis was used to compare a 5 versus 6 factor model in an applied setting. In addition, criterion-related validity coeffi cients were examined for the 2 inventories. Two Big Five measures were used-1 was an adjective-based bipolar inventory and the other was a q uestionnaire (NEO-Personality Inventory; PI)-to shed light on the rela tionships between inventory characteristics, factor structure, and cri terion-related validity. The sample consisted of 423 flight attendant trainees. Results indicated that the 6 factor model provided a better fit for both measures compared with the 5 factor model. Scales from th e NEO-PI were significantly correlated with measures of training succe ss, whereas scales from the bipolar inventory were not.
