Abstract

Background: Nursing home residents with dementia commonly experience low food intake, leading to negative functional and nutritional consequences. While the importance of staff-resident (dyadic) interactions during mealtime is acknowledged, little research has examined the role of dyadic verbal interactions on food intake. Objectives: This study aimed to examine the relationship between food intake and dyadic verbal interactions. Methods: This study was a secondary analysis of 110 videotaped observations of mealtime care interactions among 25 residents with dementia and 29 staff(42 unique dyads) in 9 nursing homes. Staff positive utterances and resident positive and negative utterances (independent variables) and food intake (dependent variable) were coded from the videotaped observations using the Cue Utilization and Engagement in Dementia video coding scheme. A linear mixed model was fit to the data. The two-way interaction effects of food type and video duration with each independent variable as well as two-way interaction effects among the independent variables were tested. Covariates included in the model were the number of years staff worked as a caregiver, and resident age, gender, and eating function. Results: The model included three significant interaction effects involving verbal variables: the interaction effect of staff positive utterances with resident positive utterances (p=.030), the interaction effect of staff positive utterances with food type (p=.027), and the interaction effect of resident negative utterances with video duration (p=0.002). Increased number of intakes of liquid food per minute was associated with increased number of staff positive utterances per minute when residents did not make positive utterances. Decreased number of intakes of solid food per minute was associated with increased number of staff positive utterances per minute, especially when residents made between 0 and 3 positive utterances per minute. As the duration of the videos increased, the number of intakes per minute increased for residents who made one or more negative utterances and decreased for residents who made no negative utterances in the videos. The number of intakes per minute was associated with resident gender in that male residents had increased number of intakes per minute compared with female residents (p=.017), and was not associated with other participant characteristics. Conclusion: Intake was associated with dyadic verbal interactions, and such relationship was complex in that it was moderated by food type and video duration. Findings support the significant role of dyadic verbal interactions on intake, and inform the development of effective, tailored mealtime care interventions to promote intake. (C) 2020 Elsevier Ltd.
