Authenticity is a familiar concept in popular culture. Despite its popularity, few studies have empirically examined the construct of authenticity. In this study, the Authenticity Scale and Authenticity Inventory, two recently created scales measuring dispositional authenticity, were examined to determine how they compare to one another as well as how they related to theoretically relevant measures including well-being and career indecision. Results from 576 undergraduate students supported the factor structure of the Authenticity Scale, but empirical support for the Authenticity Inventory was not found. Findings indicated that the Authenticity Scale was strongly related to well-being and moderately correlated with career indecision. Small correlations between the Authenticity Scale and the Self-Concept Discrepancy Scale provided evidence that the constructs of authenticity and congruence are related but measure different things. The clinical and research implications of this study are explored and encourage a broader perspective in conceptualizing vocational concerns. The empirical support found for the Authenticity Scale advocates for its use in future research applications.
