| Abstract: | Introduction: In healthy individuals, secretions are typically managed through reflexive swallowing or coughing. Impairments in sensory or motor function, however, may hinder laryngo-pharyngeal clearance, leading to hypopharyngeal secretion accumulation and compromised swallowing safety. This study aimed to translate the Murray Secretion Scale into Turkish (MSS-TR) and to evaluate its content validity and inter- and intra-rater reliability. The primary goal was to determine whether the Turkish version of the scale is a reliable and valid tool for clinical use in assessing pharyngolaryngeal secretion severity during fiberoptic endoscopic evaluation of swallowing (FEES). Methods: The study involved a multi-step process: (1) translation and back-translation of the original Murray Secretion Scale, (2) expert review to establish content validity using the Content Validity Index (CVI) and (3) reliability testing using 40 FEES recordings assessed by four experienced speech-language therapists. Intra-rater reliability was evaluated via the Wilcoxon signed-rank test and Kendall's tb, while inter-rater reliability was assessed using Fleiss' Kappa and percentage agreement. Results: Content validity was confirmed with a CVI of 0.86 for the overall scale, with the highest agreement (CVI = 1.00) for the most severe score category. Intra-rater analyses showed no significant differences between repeated evaluations (p > 0.05) and demonstrated high ordinal consistency (Kendall's tb: 0.933-1.000). Inter-rater reliability was substantial to almost perfect for all score levels, with Fleiss' Kappa values ranging from 0.634 to 0.862 across sessions. The overall percentage agreement among raters was 94.4%. However, grade 2 on the MSS-TR showed slightly lower levels of compliance, indicating potential clinical uncertainty in this category. Conclusion: The MSS-TR showed strong content validity and high intra- and inter-rater reliability, supporting its use as a standardized instrument in Turkish clinical practice. These data indicate that the scale can reliably evaluate secretion severity during swallowing assessments, aiding clinical decision-making in dysphagia management. Additional research is necessary to investigate how it applies across various patient populations and clinical settings. |
