Anticipated compliance and quality of life measures for individuals consuming thickened liquids: Perceptions of taste, texture, palatability, and enjoyment given beverage appearance
MetadataShow full item record
This study addressed: (a) effect appearance has on perceived taste, texture, palatability, and enjoyment of thickened liquids, (b) predicted effects of thickened liquids on compliance and quality of life based on duration of time the individual is asked to consume the liquid, (c) quality of life factors related to thickened liquid consumption. The effect of appearance on perceived taste and enjoyment of thickened liquids has little empirical evidence, despite being a common treatment for dysphagia. Additionally, the effect thickened liquids have on quality of life has not been well-studied. Thickened juice was presented in masked/un-masked trials. Participants were prompted to taste each juice and rate a number of factors (taste, texture, etc.). Afterwards, participants were asked to predict their anticipated compliance to drink thickened liquids for a specified duration (1 week, 3 years, etc.). Participants were asked to rate their anticipated quality of life based on the duration of thickened liquid intake. Finally, participants were asked to describe the extent drinking thickened liquids would have on their life. Presentation of thickened liquids, specific to masking, was shown to have an insignificant effect. Ratings of anticipated compliance as a function of duration were found to have significant multivariate effect. Ratings of anticipated quality of life as a function of duration were found to have significant multivariate effect. Themes from qualitative interviews on quality of life, included: compliance issues, social participation barriers, routine/convenience factors, and enjoyment changes. Results of this study demonstrate increased need for support surrounding compliance issues and reduction of social participation barriers. Qualitative and quantitative data validate each other, suggesting strong triangulation.
