The Stability, Reliability, and Validity of Videofluoroscopy Measures for Patients with Head and Neck Cancer

Abstract

The purpose of this study was to contrast the psychometric properties (stability, test-retest reliability, construct, and concurrent validity) of three different tools used for evaluating videofluoroscopy swallowing studies (VFSS): (1) rating the presence or absence of a swallowing disorder, (2) the Bethlehem Assessment Scale (BAS), and (3) biomechanical measures. These three tools were applied to the same three examinations of two different consistencies (liquid and semisolid), taken from 40 VFSSs of patients with head and neck (H&N) cancer. Stability of swallowing across three swallows was a concern for three measures with the liquid consistency and nine measures with the semisolid consist..
