The purpose of this study was to examine and explore implementation strategies for the International Dysphagia Diet Standardization Initiative (IDDSI) in terms of training effects and on the classification and preparation of texture-modified foods and liquids for people with dysphagia. The IDDSI is a culturally sensitive, international rating system for the classification and preparation of texture-modified foods and thickened liquids for people with swallowing disorders. This is important in that providing inaccurately classified foods and liquids to people with swallowing disorders may be adverse, resulting in aspiration of swallowed material into the airway which may lead to negative respiratory health outcomes or asphyxiation. Though self-study materials for the IDDSI are available online at no cost, no investigations to date have formally evaluated self-study as an educational modality and the associated effects on classification and preparation accuracy for food and liquid consistencies. Furthermore, no investigations to date have evaluated whether additional training beyond self-study may be necessary to produce reliable and accurate classification and preparation of foods and drinks. Finally, no published research to date has investigated the generalization of a training program to patients and potential caregivers without formal dysphagia experience. This investigation used a quantitative, between and within-subjects research design. Sixty-eight participants completed three tasks: (a) knowledge quiz, (b) diet classification, and (c) preparation. Participants were enrolled in self-study (SS) or self-study plus hands-on training (SS+) tracks. In summary, both SS and SS+ groups improved in their ability to accurately classify foods and drinks using IDDSI testing methods however they were not statistically significantly different from one another. Second, there were no significant predictive factors for performance found in any task for socioeconomic status or personal and professional identity. Regarding training experiences, participants felt they learned valuable information and improved in their ability to use IDDSI testing methods for diet classification. However, participants indicated that additional training would be important as they consider implementing the IDDSI framework outside of a training environment. These findings suggest that the improvements in classification accuracy using IDDSI testing methods can be gained through self-study and self-study plus hands-on training. However, neither group performed perfectly in classification and preparation of foods and drinks. Therefore, future studies should aim to recruit more robust participant groups and explore underlying reasons for incorrect classification and preparation of texture-modified diets. The long-term goal of this work is to improve overall health outcomes for people with dysphagia and provide patients and caregivers of those with dysphagia the tools necessary for optimal health outcomes.
