Patients can evaluate the humanistic behaviors of their physicians using the PHBQ. There is good correlation between the PHBQ and patient satisfaction, which supports the validity of the PHBQ. The relative lack of agreement between patients and attending physicians suggests different observations, criteria, or standards. The higher ratings from patients in the clinic compared with those from patients in the hospital suggest that residents' behaviors are different or that patients have different observations, criteria, or standards in the two settings. Therefore, a complete assessment of residents' humanistic behaviors may require sampling in both settings.
