The authors found that overall, intrarater reliability--the degree of agreement for multiple repetitions of videofluoroscopy measures by a single rater--was better than interrater reliability--the degree of agreement between raters on ordinal visuoperceptual variables (e.g., Pharyngeal Residue Severity Scale, Penetration Aspiration Scale). Included studies varied on a number of reliability measurements (e.g., method of measurement, presence or absence of pre-experimental training of raters, applied bolus consistency) and had a number of methodological concerns (e.g., randomization of swallows, representative sample, stable rater or subject characteristics). The authors conclude that in order to achieve inter- and intrarater reliability of videofluoroscopy, raters must use well-defined guidelines for assessing swallowing function using ordinal visuoperceptual measures and protocoled pre-experimental training.
