The current study applied Holland's RIASEC typology to develop a "Physician Skills Inventory". We identified the transferable skills and abilities that are critical to effective performance in medicine and had 140 physicians in 25 different specialties rate the importance of those skills. Principal component analysis of their responses produced three major components that aligned with the RIASEC code of Investigative-Realistic-Social (IRS) for physicians. The investigative type fit with problem-solving skills, the realistic type fit with psychomotor skills, and the social type fit with counseling skills. The "Physician Skills Inventory" may be used in helping medical students profile their skills for further development or remediation and for matching their skills to the requirements of different specialties.
