Fake It 'til You Make It? Measuring Impostor Syndrome in the Workplace

This study describes the development and preliminary validation of a workplace imposter syndrome measure. Exploratory factor analysis with orthogonal rotation revealed two factors, “underestimating contributions” (α = .95) and “external validation” (α = .83). Relations with previously validated measures of work self-efficacy, perceived stress, anxiety, and job satisfaction are reported.
