Exploring the Relationship Between Imposter Phenomenon and Myers-Briggs Personality Types in Pharmacy Education

To investigate the relationship between imposter phenomenon (IP) and Myers-Briggs Type Indicator (MBTI) personality types in pharmacy students.

This was a retrospective, observational study of doctor of pharmacy students who had previously completed MBTI and Clance Imposter Phenomenon Scale (CIPS) assessments. CIPS scores and categories were compared between the 4 MBTI personality type dichotomies using independent samples t tests and chi-square.

Mean CIPS score for included pharmacy students (N = 668) was 62.52 (SD 14.82). Clance Imposter Phenomenon Scale scores were significantly higher in students with MBTI of introversion (mean 64.14, SD 14.27), intuition (mean 63.80, SD 15.78), and perceiving (mean 64.38, SD 15.55) as compared to their dichotomous counterparts. No significant difference in mean CIPS scores was found within the thinking/feeling dichotomy. When analyzing IP risk associated with the various MBTI personality dichotomies, introverts were at a 1.8 times greater risk of high/severe IP than extroverts. Additionally, students with perceiving personality types were at a 1.4 times greater risk of high/severe IP than those with judging personality types.

Our study suggests that pharmacy students with introversion, intuitive, and perceptive personality types exhibit higher CIPS scores, and those with introversion or perceptive personality types are at risk for high/severe IP. Given the common MBTI types and a high degree of IP in pharmacy students, our findings underlie the need for open, targeted discussions about IP and proactively incorporating strategies and resources within a curriculum to support students in normalizing and easing anxiety.
