Assessing medical students' personalities: a parallel comparison of normed and perception-based metrics.

Various methodologies have been applied in the study of physicians' and medical students' personalities. Little, however, has been reported on distinguishing medical students' self-perceptions from their objectively measured personality traits. 687 first-year medical students at three U.S. medical schools were administered the 16PF and a parallel, author-generated, self-rating form. Paired sample t tests yielded significant differences between students' perceived personality traits vs normed measures of these traits on 14 of 16 personality factor dimensions. Students self-attributed greater magnitudes of socially acceptable traits than their objective scores indicated, as well as less domineering, suspicious, and self-doubting. Implications for admissions and career counseling are discussed.
