The behavior of 15 internal medicine residents, each with 10 patients, was observed through a one-way mirror. Ratings by the patients of satisfaction with their physicians were also obtained. Patient satisfaction correlated strongly with ratings for physician courtesy and information-giving, Nonverbal behaviors such as eye contact, bodily positioning, and physical contact did not correlate with patient satisfaction. The correlations between physician behavior and patient satisfaction did not hold for the four women physicians studied.
