Retention of interviewing skills learned by first-year medical students: a longitudinal study.

A pilot interviewing course was offered as an elective to first-year medical students in the spring of 1985. A quasi-experimental pre-test/post-test control group demonstrated that students who took the course exhibited a significant increase in interviewing skills. Subjects, 15 in the experimental group and 11 in the control group, were assessed in each of the following 3 years. Data consisted of five 10-minute videotaped interviews with real or stimulated patients for each subject and subject's responses on a degree of confidence, familiarity and anxiety scale. Interviews were rated on 43 behaviours by two independent coders with a 90% simple agreement. The experimental group did not maintain their scores on interviewing skills and both groups showed a significant decline in nine skills comprising empathy. The only significant difference between the groups in fourth year was on the degree of confidence experienced. While interviewing skills can be learned they decline in the clinical years as students learn medical problem-solving. If medical students are to graduate with their original empathy intact, a follow-up course in fourth year is indicated.
