Previous work has shown that doctors, nurses and relatives are inaccurate at estimating the comprehension problem of stroke patients. Possible factors that influence the accuracy of these judgements were studied, including confidence of the respondents, the severity of the comprehension problems of the patients and factors specific to relatives (educational background and the length of the relative's relationship with the patient). Doctors, nurses and relatives involved with 30 recently aphasic stroke patients were asked to estimate how patients would perform on the comprehension sections of two tests (Western Aphasia Battery and Functional Communication Profile). Results show that although all respondents over-estimated patients' comprehension abilities, they were more accurate for patients who had mild problems. Doctors and nurses who were more confident about their predictions tended to be more accurate on some parts of the tests than those with less confidence, whereas relatives were equally inaccurate when giving high and low confidence judgements. Length of relationship and educational level did not predict relative's accuracy.
