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

Abstract

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.
