Objectives:
To investigate global and momentary effects of a tablet-based non-pharmacological intervention for nursing home residents living with dementia.
Design:
Cluster-randomized controlled trial.
Setting:
Ten nursing homes in Germany were randomly allocated to the tablet-based intervention (TBI, 5 units) or conventional activity sessions (CAS, 5 units).
Participants:
N = 162 residents with dementia.
Intervention:
Participants received regular TBI (n = 80) with stimulating activities developed to engage people with dementia or CAS (n = 82) for 8 weeks.
Measurements:
Apathy Evaluation Scale (AES-I, primary outcome), Quality of Life in Alzheimer's Disease scale, QUALIDEM scale, Neuropsychiatric Inventory, Geriatric Depression Scale, and psychotropic medication (secondary outcomes). Momentary quality of life was assessed before and after each activity session. Participants and staff were blinded until the collection of baseline data was completed. Data were analyzed with linear mixed-effects models.
Results:
Levels of apathy decreased slightly in both groups (mean decrease in AES-I of .61 points, 95% CI -3.54, 2.33 for TBI and .36 points, 95% CI -3.27, 2.55 for CAS). Group difference in change of apathy was not statistically significant (β = .25; 95% CI 3.89, 4.38, p = .91). This corresponds to a standardized effect size (Cohen's d) of .02. A reduction of psychotropic medication was found for TBI compared to CAS. Further analyses revealed a post-intervention improvement in QUALIDEM scores across both groups and short-term improvements of momentary quality of life in the CAS group.
Conclusions:
Our findings suggest that interventions involving tailored activities have a beneficial impact on global and momentary quality of life in nursing home residents with dementia. Although we found no clear advantage of TBI compared to CAS, tablet computers can support delivery of non-pharmacological interventions in nursing homes and facilitate regular assessments of fluctuating momentary states.
