Aim: To study the sensitivity, specificity, predictive value and posttest probability of common seven ways for screening dysphagia. Methods: Fifty-six consecutive inpatients with dysphagia after stroke were enrolled in the study. They completed the seven screening tests and videofluorography. The latter included the sensitivity, specificity, predictive value and posttest probability. Results: The highest sensitivity (95.8%) was found in test 3, 4 and 6, the best specificity (70.7%) in test 7, the highest positive predictive value (70.0%) in test 2, the highest negative predictive value(90.0%) in test 3 and 4, and the beat posttest probability(63.2%) in test 1. The indexes in test 3 were completely coincident with those in test 4 so that the indexes in the two tests could be interchanged. Conclusion: Test 3 and 4 is preferred in clinic and test 1 and 2 is secondary.
