AbstractPrior to exercise treadmill testing (ETI), I 57 patients (92 males and 65 females) were interviewed twice separately, using a Thai version of the Rose questionnaire for angina pectoris. One interview was conducted by a physician and the other by a nurse.The questionnaire res- ponses were compared with ETT results. Based on physician-conducted interview, the Rose questionnaire had a sensitivity of 30.3 per cent, a specificity of 83.9 per cent, a positive predictive value of 35.3 per cent, a negative predictive value of 81.9 per cent, and the total accuracy of 72.6 per cent. There were gender differences in the validity of the questionnaire, with higher specificity. higher positive predictive value, and lower negative predictive value in males than in females. The sensitivity and accuracy were not different between the two sexes. In 87.9 per cent of cases, res- ponses to physician-conducted and nurse-conducted interview were the same. There were no significant differences between responses to the questionnaires by the physicians and by the nurses.
