Abstract Many of the discrepancies reported to date in empirical investigations impostor phenomenon (IP) may be due part (a) use different methods for identifying individuals suffering from this syndrome (impostors), (b) common a median split procedure classify subjects, and (c) fact that subjects many studies were drawn impostor-prone samples. In study, we compared scores independently identified impostors nonimpostors on two instruments designed measure IP: Harvey's I-P Scale Clance's IP Scale. The results suggest scale more sensitive reliable instrument. Cutoff score suggestions both are offered.
