This article describes the results of a three-hour training program that teaches residents a patient-centered counseling approach to smoking cessation, emphasizing questioning and exploring feelings, rather than providing information. Fifty internal medicine and family practice residents affiliated with a university medical center were assessed before and after training using questionnaires and videotape documenting changes in their knowledge about smoking, attitudes concerning intervention, and intervention skills. The residents showed a significant increase in knowledge and perceived themselves as having significantly more influence on their patients who smoke after completion of the training program. Counseling skills improved significantly in the use of questions and exploring feelings as judged by blind evaluation of videotapes. The results of this three-hour training program suggest that physicians in training are responsive to the teaching of specialized skills deemed important for promoting health behavior changes in their patients.
