Effects of examinee gender, standardized-patient gender, and their interaction on standardized patients' ratings of examinees' interpersonal and communication skills.

Abstract

To assess the effects of examinee gender, standardized-patient (SP) gender, and, in particular, their interaction on ratings made by SPs of examinees' interpersonal and communication skills in a performance-based examination of clinical competence. The examination was administered to four classes of senior medical students (about 70 per class) at Southern Illinois University School of Medicine, 1988-1991. The skill dimensions tested were clarity of communication, thoroughness of explanation, professional manner, personal manner, and overall patient satisfaction. Split-plot analyses of variance were used. There was no interaction of examinee gender and SP gender for any of the five rating scales. There was no main effect of examinee gender for four of the five scales; however, for personal manner, women students were rated slightly higher than men students. There was a main effect of SP gender, but the effect was not consistent from rating scale to rating scale or from class to class. Nevertheless, differences in ratings given by men and women SPs should not be of psychometric concern, since the ratings of men and women examinees are necessarily affected alike. Except for the women examinee's higher performance in personal manner, the men and women examinees generally performed equally well with respect to interpersonal and communication skills, and they performed equally well regardless of the gender of the SP.
