Abstract: | The stability and replicability of the Five‐Factor model of personality across samples and testing purposes remain a significant issue in personnel selection and assessment. The present study explores the stability of a new Greek Big Five personality measure (TPQue) across different samples in order to explore the suitability of the measure in personnel selection and assessment. The factor structure of the measure across three samples (students, employees, and job applicants) is examined. The results of exploratory and confirmatory factor analyses show that the five‐factor structure remains intact for the students’, the applicants’ and the employees’ samples – contrary to previous studies – with all the sub‐scales of the personality measure (TPQue) loading on the intended factors. Furthermore, congruence coefficients between the samples justify the stability of the model in the working settings. |
