Cronbach’s alpha coefficient 0.86 based on 15 (25.4%) were dysphagic, while 10 (16.9%) showed aspiration VFSS. sensitivity specificity predicting 96.7 91.2%; therefore, could prognostic aspiration. positive predictive value (PPV), negative (NPV), pre- posttest probabilities 0.67, 1, 16.9%, 66.7%, respectively. In summary, demonstrated reliability also feasibility Iranian Further evaluation larger subject would suggested.
