Abstract

To investigate the validity and reliability of the Practical Assessment of Dysphagia (PAD) test as a quantitative and organ-specific test for stroke patients. In this study, PAD test data from 109 patients with stroke were used. The internal consistency of the PAD was analyzed using Cronbach’s α value. Inter- and intra-rater reliabilities of the PAD were analyzed using Kappa coefficient. Concurrent validity was evaluated based on the correlation between PAD and the videofluoroscopic swallowing study (VFSS). The diagnostic accuracy of the PAD test in patients with stroke was measured using the area under the receiver operating characteristic (ROC) curve. Intra- and inter-rater reliabilities (Intra-class Correlation Coefficient (ICC) = 0.98 and 0.99, respectively) were significant (p < 0.001) for the total PAD score. The functional dysphagia scale (FDS) score and penetration-aspiration score (PAS) correlated significantly with PAD (p < 0.001). The results of the ROC curve analysis with various cut-off points showed that the PAD test had high sensitivity and specificity. The PAD has high reliability and validity. Therefore, it is a useful screening test for dysphagia in patients with stroke.
