Implementation Strategies for the International Dysphagia Diet Standardisation Initiative (IDDSI), Part I: Quantitative Analysis of IDDSI Performance Among Varied Participants.

Purpose The International Dysphagia Diet Standardisation Initiative (IDDSI) is an international standardized framework for texture-modified diets (TMDs). However, user accuracy in conducting IDDSI testing methods are unknown. The aims of this study were threefold: (a) to describe performance on two tasks (an IDDSI knowledge quiz and a TMD sample classification task), (b) to determine interrater and intrarater agreement for classification task performance, and (c) to determine predictive relationships between socioeconomic factors or prior knowledge on task performance.
