Doctors' perception of patients' cognitions and complaints in irritable bowel syndrome at an out-patient clinic.

Functional abdominal complaints (IBS) are widespread in the general population, especially among women. Non-organic dimensions of the complaint such as complaint-related cognitions and behaviour appear to be related to the prognosis. The prognosis could possibly be improved by changing these factors during medical consultations. Therefore, doctors have to perceive patients' cognitions and behaviour. But, do they perceive them correctly? One hundred and twenty patients with functional abdominal complaints referred to an out-patient clinic for internal medicine completed a questionnaire about their complaints and their complaint-related cognitions, behaviour, and anxiety prior to the first consultation. After the first consultation, doctors completed a similar questionnaire indicating their perceptions of patients' cognitions, anxiety, behaviour, and complaints. Complaints were perceived better than cognitions, anxiety, and behaviour. Doctors underestimated patients' expectations and secondary complaints and overestimated patients' pain-related attributions, and their catastrophizing and self-efficacy cognitions.
