RESUMEN
BACKGROUND AND AIM: The impostor phenomenon (IP) was defined in 1978 as an "internal feeling of intellectual phoniness felt by people with outstanding academic and professional achievements." This study aims to estimate the prevalence and predictors of IP among medical students. METHODS: A cross-sectional study was conducted from November 2022 to May 2023. A total of 200 medical students from years one to five participated in the survey; the response rate was 82.5% (165). A stratified random sampling technique was used to select groups of male and female Jouf University medical students from the 1st, 2nd, 3rd, 4th, and 5th batches of the 2022 to 2023 academic year. An e-mail with a self-administered questionnaire comprising the Clance IP scale and a consent form was sent to all participants. The identities of the students were kept anonymous to eliminate response bias. Participation was voluntary. Data were presented in terms of numbers and percentages; a chi-square test was used to compare categorical variables; and multivariable analysis was used to determine predictors of IP using SPSS Statistics version 20 (IBM Corp., Armonk, NY, USA). RESULTS: A total of 165 students responded to the questionnaire, with a response rate of 82.531%; 47.30% were males, and 86 (52.10%) were females. The findings indicate that 12 (7.3%), 83 (50.30%), 59 (35.80%), and 11 (6.70%) medical students, respectively, suffered from few, moderate, frequent, and intense imposter features. Results also showed that 13 (56.50%) first-year students suffered from moderate IP experiences, and 10 (43.50%) had frequent IP experiences. It was observed that for students in the first year, the academic performance represented by a student's grade point average (GPA), monthly family income, father's educational level, mother's educational level, and marital status are predictors of impostor experience. CONCLUSION: The study's findings show that impostor syndrome is a common problem among medical students and that being in the first year of medical school can increase the incidence of suffering from it. The problem-based learning system in medical school can contribute to impostor syndrome among medical students. Both low-achieving and high-achieving students suffer from impostorism.
