A randomized clinical trial of theory-based activities for the behavioral symptoms of dementia in nursing home residents.

ABSTRACT: To test the main and interactive effects of activities derived from the Need-Driven Dementia-Compromised Behavior model for responding to behavioral symptoms in nursing home residents.Randomized double-blind clinical trial.Nine community-based nursing homes.One hundred twenty-eight cognitively impaired residents randomly assigned to activities adjusted to functional level (FL) (n=32), personality style of interest (PSI) (n=33), functional level and personality style of interest (FL+PSI) (n=31), or active control (AC) (n=32).Three weeks of activities provided twice daily.Agitation, passivity, engagement, affect, and mood assessed from video recordings and real-time observations during baseline, intervention, random times outside of intervention, and 1 week after intervention.All treatments improved outcomes during intervention except mood, which worsened under AC. During intervention the PSI group demonstrated greater engagement, alertness, and attention than the other groups; the FL+PSI group demonstrated greater pleasure. During random times, engagement returned to baseline levels except in the FL group in which it decreased. There was also less agitation and passivity in groups with a component adjusted to PSI. One week after the intervention, mood, anxiety, and passivity improved over baseline; significantly less pleasure was displayed after withdrawal of treatment.The hypothesis that activities adjusted to FL+PSI would improve behavioral outcomes to a greater extent than partially adjusted or nonadjusted activities was partially supported. PSI is a critical component of individualized activity prescription.

Project description:Background. Quality staff-resident communication is crucial to promote outcomes in nursing home residents with dementia requiring assistance during mealtimes. Better understanding of staff-resident language characteristics in mealtime interactions help promote effective communication, yet evidence is limited. This study aimed to examine factors associated with language characteristics in staff-resident mealtime interactions. Methods. This was a secondary analysis of 160 mealtime videos involving 36 staff and 27 residents with dementia (53 unique staff-resident dyads) in 9 nursing homes. We examined the associations of speaker (resident vs. staff), utterance quality (negative vs. positive), intervention (pre- vs. post-communication intervention), and resident dementia stage and comorbidities with expression length (number of words in each utterance) and addressing partner by name (whether staff or resident named their partner in each utterance), respectively. Results. Staff (utterance n = 2990, 99.1% positive, mean = 4.3 words per utterance) predominated conversations and had more positive, longer utterances than residents (utterance n = 890, 86.7% positive, mean = 2.6 words per utterance). As residents progressed from moderately-severe to severe dementia, both residents and staff produced shorter utterances (z=-2.66, p = .009). Staff (18%) named residents more often than residents (2.0%; z = 8.14, p < .0001) and when assisting residents with more severe dementia (z = 2.65, p = .008). Conclusions. Staff-resident communication was primarily positive, staff-initiated, and resident-oriented. Utterance quality and dementia stage were associated with staff-resident language characteristics. Staff play a critical role in mealtime care communication and should continue to initiate resident-oriented interactions using simple, short expressions to accommodate resident declining language abilities, particularly those with severe dementia. Staff should practice addressing residents by their names more frequently to promote individualized, targeted, person-centered mealtime care. Future work may further examine staff-resident language characteristics at word and other levels using more diverse samples.

Mixed-effects models was used to examine the relationships between factors and language characteristics in staff-resident mealtime interactions. The independent variables were speaker (resident vs. staff), utterance quality (negative vs. positive), intervention (pre- vs. post-communication intervention), and resident dementia stage and comorbidities. The dependent variables were expression length (number of words in each utterance) and addressing partner by name (whether staff or resident named their partner in each utterance). All models included staff, resident, and staff-resident dyad as random effects.ResultsStaff (utterance n = 2990, 99.1% positive, mean = 4.3 words per utterance) predominated conversations and had more positive, longer utterances than residents (utterance n = 890, 86.7% positive, mean = 2.6 words per utterance).
