Medical students' perceptions of the college environment and interactions with peers and faculty were studied at the University of North Carolina, Duke University, Wake Forest University, and East Carolina University. A total of 76 black medical students (65% of the 117 black students in North Carolina's four medical schools) responded to a questionnaire in 1980. Results indicated that large levels of expressed negativism by black medical students was associated with white faculty (i.e., various forms of behavior by white faculty were perceived to cause negative responses). This was in sharp contrast to findings related to black faculty. Students responded to questions using a Likert-type scale about: how often they experienced verbal or nonverbal behaviors from white and black professors that generated negative responses (either internally or externally); how often the general behavior of their medical school professors and peers effected negative responses; how often black medical students were treated positively by white and black faculty; the extent to which they felt ignored in labs by faculty or assistants; perceptions of biased grading; perceptions of racially biased comments and actions in clinical settings; and stress in relation to academics and finances.
