Activities of Daily Living Assessment among Nursing Home Residents with Advanced Dementia: Psychometric Reevaluation of the Bristol Activities of Daily Living Scale

Acceptability and Effectiveness of a Dementia-Care Program Delivered by Community-Based Agency Staff

BACKGROUND AND OBJECTIVES

Few proven dementia-care programs are integrated into community-based agencies. We report on the acceptability and effectiveness of an evidence-based program, Care of People in their Environment (COPE), delivered by community-based agency staff.

RESEARCH DESIGN AND METHODS

Pretest/post-test design with 3 data points (baseline, 3-month program completion, 6-month follow-up). COPE was delivered by 6 occupational therapists and 4 social workers at 2 agency sites with people living with dementia and caregivers. Staff assessed the interests and abilities of people living with dementia, home safety, caregiver challenges, and readiness to learn strategies. Staff provided dementia education, stress reduction, and nonpharmacological techniques tailored to caregiver-identified challenges. Acceptability (3- and 6-months), included completed sessions, upset with and confidence managing care challenges, strategies used, and program satisfaction. Effectiveness (3- and 6-months) included people living with dementia's health events (falls, emergency room visits, hospitalizations, and 911 calls), rehospitalization risk and functional dependence; and caregiver well-being and readiness. Benefits by in-person (n = 188) versus virtual/hybrid (n = 46) delivery due to Coronavirus Disease-2019 were evaluated.

RESULTS

Of 843 dyads screened, 271 (32.1%) enrolled, 246 (90.8%) completed COPE, and 234 (95.1%) completed ≥1 follow-up. Regarding acceptability, caregivers completed about 8 sessions, reported improved confidence and upset (p < .001), most implemented strategies 3-months (72.8%) and 6-months (83.5%), and expressed high program satisfaction. For effectiveness, compared to baseline, odds of people living with dementia's health events were lower including rehospitalization risk, although functional dependence increased; caregiver well-being (3-, 6-months, p < .001) and readiness (3-months, p < .01) improved. Outcomes did not differ by delivery mode.

DISCUSSION AND IMPLICATIONS

Acceptability and effectiveness were strong. COPE resulted in tangible improvements for families regardless of delivery mode.

Effects of a 16-week multimodal exercise program on activities of daily living in institutionalized individuals with dementia

We aimed to examine the effects of a 16-week multimodal exercise program (MEP) on activities of daily living (ADL) in individuals with dementia (IWD). Furthermore, we investigated the participants’ individual response to the MEP and whether baseline cognitive and motor performance explain ADL performance. We conducted a multicenter randomized controlled trial (RCT) involving 319 participants aged ≥ 65 years with mild to moderate dementia. ADL were assessed at baseline and after the 16-week intervention using the Barthel Index (BI), the Erlangen Test of Activities of Daily Living (E-ADL) and the 7‑item Physical Performance Test (PPT-7). We additionally assessed cognitive and motor performance using standardized and validated assessments. Intervention effects were examined through two-factor analysis of variance with repeated measurements applying a per protocol and an intention-to-treat analysis. We compared baseline cognitive and motor performance between positive-responders (positive-R), non-responders (non-R), and negative-responders (negative-R) and examined cognitive and motor performance as potential cofounders of ADL by conducting multiple regression analyses. There were no significant time×group effects on ADL. Between 20 and 32% of participants responded positively to the intervention, i.e., improved ADL performance from baseline to follow-up. Positive-R had worse baseline motor performance compared to non-R. Cognitive and motor performance explained up to 51.4% of variance in ADL. The MEP had no significant overall effect on ADL in IWD. This may be related to insufficient exercise intensity. However, our results indicate that the response to the MEP depends on individual prerequisites which should thus be considered in further research on individual exercise approaches.

Is Barthel Index Suitable for Assessing Activities of Daily Living in Patients With Dementia?

OBJECTIVES

To evaluate application of the Barthel Index (BI) in assessing basic activities of daily living (ADL) of patients with dementia using Rasch analysis.

DESIGN

A multi-country cross-sectional study.

SETTING AND PARTICIPANTS

Nineteen long-term care facilities located in China, Japan, South Korea, and Thailand. A total of 644 patients with dementia were included.

METHODS

Unidimensionality, global and item fit, local dependence, person-item targeting, threshold disordering, and differential item functioning (DIF) were examined. Negative correlations between scores for DIF items and Neuropsychiatric Inventory Nursing Home version (NPI-NH) were evaluated.

RESULTS

Item reliability (1.0) and person reliability (.88) were acceptable. The Rasch dimension explained 72.9% of the variance (Eigenvalue = 27), while the first contrast explained 6.6% (Eigenvalue = 2.4). The "mobility" was misfitting to the Rasch model (infit mean square = 1.86). The overall difficulty of the BI exceeded patients' ability (person location = -2.27 logits). The "stairs climbing" and "mobility" showed narrow category thresholds (< 1.4 logits). The location of "controlling bladder" and "toilet use" overlapped. Removing "stairs climbing", collapsing categories with narrow threshold widths in "mobility", and combining "controlling bowel" and "controlling bladder" into one item, improved unidimensionality, and item fit of the scale. Only three items ("grooming", "dressing", and "toilet use") were free from DIF across countries. The scores for "feeding" were negatively related to scores for "disinhibition" (r = -0.46, P < 0.01), and scores for "controlling bowel" were negatively related to scores for "disinhibition" (r = -0.44, P < 0.01), "agitation" (r = -0.32, P < 0.05), and "aggression" (r = -0.27, P < 0.01) in Japanese samples.

CONCLUSIONS AND IMPLICATIONS

The performance of the BI for assessing patients with dementia might be compromised by misfit items, person-item mistargeting, measurement gaps, redundant items, narrow threshold width, and item bias. Mobility ability might not be helpful for determining capability of basic ADL in the patients. Comparisons of BI scores between countries should be undertaken with caution due to item bias. Neuropsychiatric symptoms might interact with basic ADL abilities of the patients. We will not suggest using the instrument in patients with dementia, without future refining to improve its performance.

Social support and high resilient coping in carers of people with dementia

High resilience is associated with improved carer outcomes. Both individual factors and the availability of social support have been linked with resilience. This study was conducted to compare socio-demographic characteristics and the availability of social support for carers with low and high resilient coping, and identify if any domain of social support predicted high resilient coping in informal carers of people with dementia. The participants in this cross sectional survey included 108 informal carers of people with dementia. Findings showed the availability of emotional/informational support was most likely to predict resilient coping and tangible support the least likely. However, when controlling for all covariates, only gender predicted high resilient coping, individual social support domains were no longer significant. Therefore, as no single domain of social support has a significantly greater influence on resilient coping, service providers should enable carers to build a wide, multi-function support network.
