Developing Referential Norms for the Big Five Personality Inventory (NEO-PI-S) Using Jordanian sample

Abstract

This study aimed at developing the referential norms for the Big-five personality factors’ inventory developed by (Costa & McCrae, 1992). Study sample consisted of (1294) individuals from both genders, their ages ranged from (13-70) years old. The means, standard deviations, frequencies, correlations, and standard T-scores were used to answer the study questions. The results indicated that the raw degrees for the five personality factors ranged from (12-60). From the raw scores, the standardized T scores with a mean of (50) and standard deviation of (10) were developed. In general, the results indicated that the inventory had acceptable stability percentages except and were close to Al-Ansari results (1997). Finally, this study has provided a step forward in the field of personality measures, and now it is ready to be used on the Jordanian society.
