In order to better understand patient differences in question asking and other information-seeking behaviors when communicating with doctors, 106 rehabilitation medicine patients were studied. Sociodemographic data, attitude measures, interview data and tape recordings of doctor-patient encounters revealed that patients desired information about a wide range of medical topics but did not engage in many information-seeking behaviors when communicating with doctors. While desiring information, patients regarded doctors as the appropriate persons to make medical decisions. Regression analyses indicated that patient information-seeking behaviors were more directly associated with situational variables (length of interaction, diagnosis, reason for visit) than with patient attitudes or sociodemographic characteristics. Patient attitudes influenced patient information-seeking behaviors only for patients with interactions lasting at least 19 minutes, indicating that a longer interaction may be necessary for patient attitudes regarding desire for information and participation in medical decisions to manifest themselves in information-seeking communication behavior.
