House officer interviewing techniques: impact on data elicitation and patient perceptions.

The relationships among physicians' interviewing techniques, the amount and type of data gathered, and patients' perceptions of the interviewing process were studied. Thirty-one Internal Medicine house officers each interviewed one of three standardized patients. The house officers' thoroughness of data collection was assessed by the patients and by a trained evaluator. A videotape of each interview was analyzed at the National Board of Medical Examiners using the interaction analysis system for interview evaluation, ISIE-81, to define house officers' interviewing techniques. From the physicians' problem-solving perspective, data elicitation was positively related to the length of the interview, asking psychosocial questions, the use of narrow questions, and the amount of time the patient talked. The patients' assessments of house officers' data-gathering thoroughness were also positively influenced by interview length, the use of narrow questions, and inquiries about their psychosocial histories. The use of broad questions by the house officer was positively related to the patient's feelings about and reaction to the interaction. This study potentially explains some of the differences that appear to exist between patients' and physicians' judgments about and perceptions of the medical interviewing process.
