Aim: The aim of this research was to investigate the factor structure, validity and reliability of the Protean Career Attitudes Scale of employees. Methods: This research was a descriptive research which investigated the psychometrics of the scale. The statistical population included the employees of Isfahan's engineer companies. The samples were 200 employees (including 78 females and 122 males) who were selected by cluster sampling method. Protean Career Attitudes Scale and Proactive Personality Scale were used. Findings: Data were analyzed by using factor analysis, correlation and multivariate analysis of variance. The results of the confirmatory factor analysis revealed that the factor-second order confirmatory factor model and two factors-first order confirmatory factor model were confirmed and were fit with data. Finally, two factors-first order confirmatory factor model a better fit. In the one factor model, protean career attitudes were the latent construct and in two factors model self-directed career management and values-driven were latent constructs. The correlation of Self-directed career management subscale and values-driven subscale with proactive personality scale was 0.66 and 0.53 (p<0/01). Internal consistency of self-directed career management subscale was 0.72 and values-driven subscale was 0.70. Test-retest reliability in three weeks in self-directed career management subscale and values-driven subscale were 0.89 and 0.90 (p<0.01). Moreover, the results of multivariate analysis of variance showed that men in both self-directed career management subscale and values-driven subscale had higher scores than women. Conclusions: Overall, diverse career path perspectives scale may be used as a reliable tool to assess the perspectives toward different career paths.
