Turkish Adaptation, Validity and Reliability Study of the State Impostor Phenomenon Scale

The purpose of the study was to adapt State Impostor Phenomenon Scale (SIPS) by Fujie into Turkish and study the validity and reliability of the adapted scale. Two different sample groups were studied for the reliability and validity of the scale. The first group in which explanatory factor analysis and Cronbach Alpha coefficient were examined consisted of 287 people with the mean age 23.84+5.32. The level of fit of the factor structure obtained by confirmatory factor analysis was examined. Accordingly, data were collected from a second group of 101 people with the mean age of this group was determined as 23.49+3.82. Results showed that State Imposter Phenomenon Scale has a stable factor structure and reliable measure in investigation of state impostor phenomenon in Turkish language.
