A Visuoperceptual Measure for Videofluoroscopic Swallow Studies (VMV): A Pilot Study of Validity and Reliability in Adults with Dysphagia

The visuoperceptual measure for videofluoroscopic swallow studies (VMV) is a new measure for analysing the recordings from videofluoroscopic swallow studies (VFSS). This study evaluated the reliability and validity of the pilot version of the VMV using classical test theory (CTT) analysis, informed...

description The visuoperceptual measure for videofluoroscopic swallow studies (VMV) is a new measure for analysing the recordings from videofluoroscopic swallow studies (VFSS). This study evaluated the reliability and validity of the pilot version of the VMV using classical test theory (CTT) analysis, informed by the consensus-based standards for the selection of health measurement instruments (COSMIN) guidelines. Forty participants, diagnosed with oropharyngeal dysphagia by fibreoptic endoscopic evaluation of swallowing, were recruited. The VFSS and administration of bolus textures and volumes were conducted according to a standardised protocol. Recordings of the VFSS were rated by three blinded raters: a speech-language pathologist, a radiologist and a phoniatrician. Inter- and intra-rater reliability was assessed with a weighted kappa and resulted in 0.889 and 0.944 overall, respectively. Structural validity was determined using exploratory factor analyses, which found four and five factor solutions. Internal consistency was evaluated with Cronbach’s alpha coefficients, which found all but one factor scoring within an acceptable range (>0.70 and <0.95). Hypothesis testing for construct validity found the expected correlations between the severity of dysphagia and the VMV’s performance, and found no impact of gender on measure performance. These results suggest that the VMV has potential as a reliable and valid measure for VFSS. Further validation with a larger sample is required, and validation using an item response theory paradigm approach is recommended.
