The Dynamic Imaging Grade of Swallowing Toxicity for Flexible Endoscopic Evaluation of Swallowing (DIGEST-FEES) represents such an outcome measure but has been validated primarily for head and neck cancer collectives. The objective of this study was, therefore, to investigate the validity of the DIGEST-FEES in patients with PD. Content validity was evaluated with a modified Delphi expert survey. Subsequently, 66 FEES videos in PD patients were scored with the DIGEST-FEES. Criterion validity was determined using Spearman's correlation coefficient between the DIGEST-FEES and the Penetration-Aspiration Scale (PAS), the Yale-Residue-Rating-Scale, the Functional-Oral-Intake-Scale (FOIS), and the swallowing-related Unified-Parkinson-Disease-Rating-Scale (UPDRS) items. Inter-rater reliability was determined using 10 randomly selected FEES-videos examined by a second rater. As a result, the overall DIGEST-FEES-rating exhibited significant correlations with the Yale-Valleculae-Residue-Scale (<jats:italic>r<\/jats:italic>\u2009=\u20090.84; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), the Yale-Pyriform-Sinus-Residue-Scale (<jats:italic>r<\/jats:italic>\u2009=\u20090.70; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), the FOIS (<jats:italic>r<\/jats:italic>\u2009=\u2009\u2009\u2212\u20090.55, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), and the UPDRS-Swallowing-Item-Score (<jats:italic>r<\/jats:italic>\u2009=\u20090.42, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Further, the DIGEST-FEES-safety subscore correlated with the PAS (<jats:italic>r<\/jats:italic>\u2009=\u20090.63, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). Inter-rater reliability was high for the overall DIGEST-FEES rating (quadratic weighted kappa of 0.82). Therefore, DIGEST-FEES is a valid and reliable score to evaluate overall pharyngeal dysphagia severity in PD. Nevertheless, the modified Delphi survey identified domains where DIGEST-FEES may need to be specifically adapted to PD or neurological collectives in the future.<\/jats:p>","DOI":"10.1007\/s00455-023-10650-6","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T17:02:03Z","timestamp":1703264523000},"page":"697-704","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Validation of the DIGEST-FEES as a Global Outcome Measure for Pharyngeal Dysphagia in Parkinson\u2019s Disease"],"prefix":"10.1007","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6094-3869","authenticated-orcid":false,"given":"Bendix","family":"Labeit","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sriramya","family":"Lapa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Muhle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonja","family":"Suntrup-Krueger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inga","family":"Claus","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florin","family":"Gandor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sigrid","family":"Ahring","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Oelenberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rainer","family":"Dziewas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tobias","family":"Warnecke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,12,22]]},"reference":[{"key":"10650_CR1","doi-asserted-by":"publisher","first-page":"311","DOI":"10.1016\/j.parkreldis.2011.11.006","volume":"18","author":"JG Kalf","year":"2012","unstructured":"Kalf JG, de Swart BJM, Bloem BR, Munneke M.
