Aims To refine the Cue Utilization and Engagement in Dementia mealtime video‐coding scheme and examine its ease of use, feasibility, and inter‐rater reliability in assessing the food intake process and dyadic verbal and nonverbal interactions. Design This study was a secondary analysis of 110 videotaped observations of mealtime interactions collected under usual care conditions from a dementia communication trial during 2011–2014. Methods The videos involved 29 staff and 25 residents with dementia (42 unique staff‐resident dyads) in nine nursing homes. Data coding and analysis were performed in 2018–2019. Logs of coding challenges with matched solutions and coding time were collected. Inter‐rater reliability was examined through rating of randomly selected 22 videos across four trained coders. Results It took a mean of 10.81 hr to code a one‐hour video using the refined coding scheme. Coding challenges, including identification of key intake process characteristics and differentiation of similar verbal or nonverbal behaviours, were identified with appropriate solutions. The refined coding scheme had good inter‐rater reliability (Cohen's Kappa range = 0.93 – 0.99, 95% CI = 0.92 – 0.99). Conclusion Findings supported preliminary evidence on feasibility, usability and inter‐rater reliability of the refined coding scheme. Future psychometric testing is needed in diverse populations with dementia across different care settings. Impact Existing tools assessing the food intake process and dyadic interactions are few and have limited feasibility and/or reliability and fail to capture the complexity and dynamics of mealtime care. The refined coding scheme showed preliminary feasibility, usability, and inter‐rater reliability. In consideration of the balance between time intensity and the richness of data obtained, the tool may be appropriate and useful in addressing certain research inquires (e.g., characterizing and clustering dyadic behaviours, temporal relationship between behaviours and intake) pertaining older adults with or without dementia and their formal or informal caregivers.
