Not all 'impostors' are created equal: A dimensional, person-centered, and theory-based analysis of medical students.

This study sheds light on the ways that medical students may experience IP, further reinforcing the notion that not all 'impostors' are created equal. Findings support the three-factor structure of the CIPS among medical students, and that most students will fall into one of four IP profiles. These profiles and their implications are discussed.
