Mealtime verbal interactions among nursing home staff and residents with dementia: A secondary behavioural analysis of videotaped observations

Aims To characterize dyadic mealtime verbal interactions and examine the associations with staff and resident characteristics. Design A secondary analysis of 110 videotaped mealtime observations collected from a dementia communication trial during 2011-2014. Methods Videos involved 25 residents with dementia and 29 staff in nine nursing homes. Verbal behaviours (utterances) were coded during 2018-2019 using the Cue Utilization and Engagement in Dementia mealtime video-coding scheme, addressing eight positive behaviours and four negative behaviours. Bivariate analyses and multivariate regression models were used. Results Staff spoke three times more frequently (76.5%) than residents (23.5%). Nearly all staff utterances were positive (99.2%); 85.1% of residents' utterances were positive and 14.9% negative. Staff positive utterances were correlated with their negative utterances and resident positive and negative utterances. Staff negative utterances were correlated with resident negative utterances. Resident positive and negative utterances were correlated. Resident positive utterances were significantly associated with staff care-giving length in the current nursing home (OR = 1.430, 95% CI = 1.008, 2.027). Resident negative utterances were significantly associated with resident gender (female versus male, OR = 11.892, 95% CI = 1.237, 114.289) and staff years worked as a caregiver (OR = 0.838, 95% CI = 0.710, 0.989). Staff positive and negative utterances were not associated significantly with any participant characteristics. Conclusions Staff engage residents using primarily positive verbal strategies. Staff-resident mealtime verbal interactions were dynamic, interactive, and complex and related to multiple individual characteristics. Impact Positive dyadic mealtime interactions are critical to engage residents in eating. Little work has characterized dyadic mealtime interactions, limiting the development of effective interventions. Findings showed staff-resident mealtime verbal interactions were primarily positive, inter-related, and associated with multiple individual characteristics. Findings inform directions to improve mealtime care practice and develop person-centred mealtime interventions targeting modifiable factors, including staff care-giving experiences.

Automated summary

Staff spoke more often than residents during mealtimes, and their verbal interactions were primarily positive. The interactions were dynamic and complex, associated with multiple individual characteristics such as staff care-giving length, resident gender, and staff years worked as a caregiver. Residents' positive utterances were significantly associated with staff care-giving length, while negative utterances were associated with resident gender and staff years of experience. Staff positive and negative utterances were not significantly associated with any participant characteristics.
