Physicians who specialize in family medicine and general practice have the potential to assume a major role in helping patients change their health promotion practices. Little is known about the proportion of routine consultation time devoted to primary prevention counseling or the factors that influence the provision of this kind of patient education. A survey of General and Family Practitioners was conducted to determine the extent to which these physicians perform health promotion counseling as well as their perceptions regarding constraints affecting their efforts, confidence in their ability to change patient's behaviors, and the training required to enhance their efforts. Differences, with respect to their health promotion practices, between General and Family Practitioners, were also examined. One hundred and ninety-five physicians completed the survey for a response rate of 68%. When year of graduation from medical school was controlled there was little difference in the health promotion practices of General and Family Practitioners. This study suggests residency training in the specialty of family medicine does not provide residents with the knowledge, confidence and skills to perform health prevention counseling at a level different than that practiced by General Practitioners.
