Based on RIAS， which is widely used abroad， we quantify the words in doctor?patient interaction. Combining with the results of questionnaire survey of patients’ satisfaction with consultation， we analyzed the relationship between doctor?patient interaction words and patients’ satisfaction. The results showed that more doctors’ biomedical information gathering， the higher the degree of information search of patients， more psychosocial information giving and positive conversation were associated with the higher patients’ satisfaction， while more doctors’ negative conversation and the older patients’ age are associated with the lower patient’s satisfaction. Therefore， it was suggested that doctors should pay more attention to psychosocial factors while focus on the patients’ disease， avoid negative language， and focus on the needs of elderly patients. Meanwhile， governments or hospitals at all levels should strengthen the popularization of disease health knowledge and physician information provision among patients， which could enhance patient satisfaction.
