Finding fault: Criticism as a care management strategy and its impact on outcomes for dementia caregivers

Sleep quality differences among caregivers for persons living with and without dementia

OBJECTIVES

This study examined the relationship between caring for a person with/without dementia and caregiver sleep quality, and analyzed the extent to which perceived benefits of caregiving and assessments of caregiver-recipient relationship quality explain the relationship between care recipient dementia status and caregiver sleep quality.

METHOD

Data were analyzed from caregivers for persons with no or probable dementia who participated in the 2017 National Study of Caregiving (NSOC) and National Health and Aging Trends Study. Caregiver sleep quality was measured using NSOC time diary interview. Perceptions of caregiving and relationship quality were assessed using 4-item surveys. We used multivariable logistic regressions to examine the association between care recipient dementia status and caregiver sleep quality controlling for covariates.

RESULTS

The sample consisted of 1,374 caregivers (mean age = 62.3, SD = 14, 68.3% women, 69.4% non-Hispanic White). In multivariable models adjusting for caregiver and care recipient characteristics, being a caregiver for someone with dementia was associated with 23% lower odds of reporting "excellent/very good" sleep quality (OR: 0.77, 95%CI: 0.61-0.98, p = 0.032). Greater perception of caregiving benefits was associated with 8% greater odds of "excellent/very good" sleep quality (AOR: 1.08, 95%CI: 1.02-1.15, p = 0.013), but did not explain the relationship between dementia and caregiver sleep quality. Positive ratings of relationship quality explained the relationship between care recipient dementia status and caregiver sleep quality (AOR: 0.82, 95%CI: 0.65-1.05, p = 0.12).

CONCLUSION

Improving assessments of relationship quality and amplifying perceptions of caregiving benefits may reduce disparities in sleep quality between caregivers of persons living with or without dementia.

How does carer management style influence the performance of activities of daily living in people with dementia?

INTRODUCTION

People with Dementia (PwD)'s performance of activities of daily living (ADLs) has been associated with apathy, cognitive deficits, carers' depression and burden. However, it is not known if the carers' management style affects ADL performance, particularly alongside PwD's cognitive deficits and apathy. Thus, the aim of this study was to explore the contribution of intrinsic (cognition, apathy) and extrinsic (carer management styles) dementia factors to ADL performance.

METHODS

PwD (n = 143) were assessed on global cognition (ACE-III); apathy (CBI-R); ADLs (Disability Assessment for Dementia-DAD). Carers' (n = 143) criticism, encouragement and active-management styles were assessed with the Dementia Management Strategy Scale (DMSS). Multiple linear regression analysis investigated contributions of carer styles, cognition, apathy (independent variables) on ADLs (dependent variable).

RESULTS

The best model explaining the variance of the DAD scores included cognition (β = 0.413, t₍₁₄₂₎  = 4.463, p = 0.001), apathy (β = -0.365, t₍₁₄₂₎  = -5.556, p = 0.001), carer criticism (β = -0.326, t₍₁₄₂₎  = -2.479, p = 0.014) and carer encouragement styles (β = 0.402, t₍₁₄₂₎  = 2.941, p = 0.004) accounting for 40% of the variance of the DAD scores.

CONCLUSIONS

This novel study demonstrated that PwD's level of apathy and the carer's use of criticism negatively affected ADL performance while PwD's cognitive abilities and carer encouragement style improved ADL performance. These findings have critical implications for the development of novel multi-component non-pharmacological interventions to maintain function and delay disease progression in dementia, as well as direct relevance to current carers and families.

Harsh communication: characteristics of caregivers and persons with dementia

Objectives: While ways to reduce caregiver burden have dominated dementia care research, there is little understanding of daily communication and its relationship to caregiver burden and depression. In this study, we sought to: (1) describe the frequency of harsh communication used by caregivers; (2) examine the relationship between harsh communication, caregiver and person with dementia characteristics; and (3) determine the contributions of caregiver depression and burden on such communication.Method: Cross-sectional baseline data were drawn from 250 dyads, who participated in the Dementia Behavior Study (NCT01892579). Hierarchical linear regression models were used to examine the relationship between dyad characteristics and harsh communication scores (using the 6-item Negative Communication Scale), controlling for three groups of covariates: sociodemographic, relationship characteristics and health factors.Results: More than half of the caregivers (mean age = 65.4, 81.2% women, 45.6% spouses) reported they felt like screaming/yelling (N = 138, 55.2%) or used a harsh tone (N = 129, 51.6%) at persons with dementia (Mini Mental Status Examination mean = 14.3, SD: 7.8) at least sometimes. When controlling for all covariates, for each unit increase in caregiver burden, harsh communication increased by 0.486 units (p < 0.001); similarly, for each unit increase in caregiver depression, harsh communication increased by 0.301units (p < 0.001).Conclusion: Over half of dementia caregivers reported they felt like or used one or more harsh forms of communication. Caregiver burden and depression were incrementally associated with greater use of negative communication. Providing caregivers with knowledge, support and specific communication skills may lessen the frequency of harsh communication and possibly reduce burden and depression.

An empowerment program for family caregivers of people with dementia

OBJECTIVES

Family caregivers of people with dementia (PWD) often feel powerless and experience decreased well-being. Our aim was to develop an intervention program based on the caregiver empowerment model (CEM) and apply it with the Korean caregivers to evaluate its effects.

DESIGN AND SAMPLE

The study population comprised 115 family caregivers (experimental group, n = 35, control group 1, n = 40, control group 2, n = 40).

METHODS

Using an experimental design with two control groups. The experimental group received a 12-week program including intensive counseling, education, and telephone calls. The control group 1 (CG1) received usual service. The control group 2 (CG2) was provided with a handbook during the first week. A mixed-effects model was used to clarify longitudinal changes in participants' outcomes.

RESULTS

The experimental group showed significantly increased caregiving appraisal (effect size in CG1 = -7.25; CG2 = -5.63), caregiving attitude (CG1 = -21.47; CG2 = -17.79), self-efficacy (CG1 = -12.42; CG2 = -10.12), and well-being (CG1 = -4.33; CG2 = -2.35) after the program.

CONCLUSIONS

The empowerment program can be used to promote family caregivers' positive adaptation and to help caregivers who care for PWD to effectively cope with their problems.
