'Living well' trajectories among family caregivers of people with mild-to-moderate dementia in the IDEAL cohort

Longitudinal Trajectories of Stress and Positive Aspects of Dementia Caregiving: Findings From the IDEAL Programme

OBJECTIVES

Understanding what influences changes over time in caregiver well-being is important for the development of effective support. This study explores differences in trajectories of caregiver stress and positive aspects of caregiving (PAC).

METHODS

Caregivers of community-dwelling individuals with mild-to-moderate dementia at baseline from the IDEAL cohort were interviewed at baseline (n = 1,203), 12 months (n = 917), and 24 months (n = 699). Growth mixture models identified multiple growth trajectories of caregiver stress and PAC in the caregiver population. Associations between study measures and trajectory classes were examined using multinomial logistic regression and mixed-effects models.

RESULTS

Mean stress scores increased over time. A 4-class solution was identified: a "high" stable class (8.3%) with high levels of stress, a "middle" class (46.1%) with slightly increasing levels of stress, a "low" class (39.5%) with initial low levels of stress which slightly increased over time, and a small "increasing" class (6.1%) where stress level started low but increased at a steeper rate. Mean PAC scores remained stable over time. A 5-class solution was identified: 3 stable classes ("high," 15.2%; "middle," 67.6%; "low" 9.3%), a small "increasing" (3.4%) class, and 1 "decreasing" class (4.5%). For stable classes, positive ratings on study measures tended to be associated with lower stress or higher PAC trajectories and vice versa. Those with "increasing" stress also had worsening trajectories of several study measures including depression, relationship quality, competence, and ability to cope.

DISCUSSION

The findings highlight the importance of identifying caregivers at risk of increased stress and declining PAC and offering them targeted support.

Differences in trajectories of quality of life according to type of dementia: 6-year longitudinal findings from the IDEAL programme

BACKGROUND

People with different types of dementia may have distinct symptoms and experiences that affect their quality of life. This study investigated whether quality of life varied across types of dementia and over time.

METHODS

The participants were 1555 people with mild-to-moderate dementia and 1327 carers from the IDEAL longitudinal cohort study, recruited from clinical services. As many as possible were followed for up to 6 years. Diagnoses included were Alzheimer's disease, vascular dementia, mixed Alzheimer's and vascular dementia, Parkinson's disease dementia, dementia with Lewy bodies, and frontotemporal dementia. Self- and informant-rated versions of the Quality of Life in Alzheimer's Disease scale were used. A joint model, incorporating a mixed effects model with random effects and a survival model to account for dropout, was used to examine whether quality of life varied by dementia type at the time of diagnosis and how trajectories changed over time.

RESULTS

The strongest associations between dementia type and quality of life were seen around the time of diagnosis. For both self-ratings and informant ratings, people with Parkinson's disease dementia or dementia with Lewy bodies had lower quality of life scores. Over time there was little change in self-rated scores across all dementia types (- 0.15 points per year). Informant-rated scores declined over time (- 1.63 points per year), with the greatest decline seen in ratings by informants for people with dementia with Lewy bodies (- 2.18 points per year).

CONCLUSIONS

Self-rated quality of life scores were relatively stable over time whilst informant ratings showed a steeper decline. People with Parkinson's disease dementia or dementia with Lewy bodies report particularly low levels of quality of life, indicating the importance of greater attention to the needs of these groups.

Trajectories of negative and positive experiences of caregiving for older adults with severe dementia: application of group-based multi-trajectory modelling

BACKGROUND

Family caregivers of older adults with severe dementia have negative and positive experiences over the course of caregiving. We aimed to delineate joint trajectories (patterns over time) for negative and positive experiences, identify risk factors associated with membership of joint trajectories, and ascertain the association between joint trajectories and caregivers' outcomes after the death of the older adult.

METHODS

Two hundred fifteen family caregivers of older adults with severe dementia in Singapore were surveyed every 4 months for 2 years, and 6 months after the death of the older adult. Using group-based multi trajectory modelling, we delineated joint trajectories for positive (Gain in Alzheimer Care Instrument) and negative (sub-scales of modified Caregiver Reaction Assessment) experiences of caregiving.

RESULTS

We identified four joint trajectories - "very high positive, low negative" (23% of caregivers), "high positive, moderate negative" (28%), "very high positive, moderate negative" (28%), and "high positive, high negative" (21%). Caregivers of older adults with more behavioural symptoms, and who did not receive strong emotional support from family were more likely to have "high positive, moderate negative" or "very high positive, moderate negative" trajectory. Compared to caregivers with "very high positive, low negative" trajectory, caregivers with "very high positive, moderate negative" or "high positive, high negative" trajectories expressed greater grief and distress, with the latter also having lower spiritual well-being and quality of life at 6 months after the death of the older adult.

CONCLUSION

The caregiving experiences for older adults with severe dementia vary between caregivers but remain stable over time. Modifiable risk factors identified for trajectories involving negative experiences of caregiving may be targeted in future interventions to improve the experience of caregiving and caregiver quality of life and distress after the death of the older adult.

Characteristics and Correlates of Perceived Physical and Psychological Health Among Family Caregivers Living With Persons With Advanced Dementia

BACKGROUND

Various factors drive a care setting shift from institutional to home settings for dementia care until the latest stage of the disease, suggesting the critical role of family caregivers living with persons with dementia.

OBJECTIVES

This study explored the characteristics and correlates of self-reported overall physical and psychological (ie, depressive symptoms and stress) health among family caregivers living with persons with dementia in Sweden.

METHODS

This cross-sectional, descriptive study used baseline data from an existing music-based intervention study of persons with dementia and their family caregivers (N = 76). Multivariable linear regression analyses were performed.

RESULTS

On average, caregivers (n = 38; mean age: 74.8 years) were slightly younger than persons with dementia (n = 38; mean age: 78.6 years). Most caregivers were female (n = 24; 63.2%) and spouses or partners of persons with dementia (n = 37; 97.4%). Caregivers' perceived relationship with their family members with dementia was the only factor associated with caregivers' self-reported overall physical health (b = -0.655, p = .046). This suggests caregivers' more frequent feeling of a good relationship with the persons with dementia was linked to better self-rated physical health among family caregivers living with persons with dementia.

CONCLUSIONS

This study highlights the importance of family caregivers' perceived relationship with persons with dementia in the context of caregivers' self-reported physical health. Future research is needed to explore the perceived relationship from the perspectives of persons with dementia and the determinants of caregiving dyads' (persons with dementia and family caregivers) perceived relationship with each other.

Long-term impact of the COVID-19 pandemic on the quality of life of people with dementia and their family carers

INTRODUCTION

Few studies have longitudinally mapped quality of life (QoL) trajectories of newly diagnosed people with dementia and their carers, particularly during coronavirus disease-2019 (COVID-19).

METHODS

In a UK cohort study, 261 newly diagnosed people with dementia and 206 family carers were assessed prior to the pandemic (July 2019-March 2020), followed up after the first lockdown (July-October 2020) and then again a year and 2 years later. Latent growth curve modelling examined the level and change of QoL over the four time-points using dementia-specific QoL measures (DEMQOL and C-DEMQOL).

RESULTS

Despite variations in individual change scores, our results suggest that generally people with dementia maintained their QoL during the pandemic and experienced some increase towards the end of the period. This contrasted with carers who reported a general deterioration in their QoL over the same period. 'Confidence in future' and 'Feeling supported' were the only carer QoL subscales to show some recovery post-pandemic.

DISCUSSION

It is positive that even during a period of global disruption, decline in QoL is not inevitable following the onset of dementia. However, it is of concern that carer QoL declined during this same period even after COVID-19 restrictions had been lifted. Carers play an invaluable role in the lives of people with dementia and wider society, and our findings suggest that, post-pandemic, they may require greater support to maintain their QoL.

Do communication interventions affect the quality-of-life of people with dementia and their families? A systematic review

OBJECTIVES

Speech, language and communication difficulties are prevalent in all dementia subtypes and are likely to considerably impact the quality-of-life of people with dementia and their families. Communication interventions provided by trained professionals are recommended for this population, but little is known about their quality-of-life outcomes. This review aims to explore the quality-of-life outcomes of communication-related interventions for people with dementia and their families.

METHODS

Seven databases were systematically searched. Reference lists from included studies and relevant systematic reviews were also hand-searched. Primary research with quantitative quality-of-life outcomes were included. Narrative analysis was utilised to identify key intervention features and to describe quality-of-life outcomes.

RESULTS

1,174 studies were identified. Twelve studies were eligible for inclusion. Studies were heterogeneous in location, participant group, methodologies, interventions and outcome measures. Four studies reported increased quality-of-life for people with dementia following intervention. No studies reported increased quality-of-life for family members.

CONCLUSION

Further research is needed in this area. The studies which reported improved quality-of-life involved multi-disciplinary approaches to intervention, involvement of family caregivers, and functional communication intervention. However, data is limited so results should be interpreted with caution. The standardised use of a communication-focused quality-of-life outcome measure would improve sensitivity and comparability of future studies.

The precariousness of living with, and caring for people with, dementia: Insights from the IDEAL programme

This paper uses precarity as a framework to understand the vulnerabilities experienced by those living with or caring for someone living with dementia. Drawing on qualitative interview data from the Improving the Experience of Dementia and Enhancing Active Life (IDEAL) programme, we attend to our participants' reflections on how they manage the condition and the wider circumstances in which this occurs. To interrogate the utility of precarity, we focus on our participants' descriptions of needs and challenges and set these alongside both the wider contexts in which they seek or offer care (formal and informal) and the sets of values attributed to different ways of living with dementia. Building on the work of Portacolone, our analysis identified four interconnected themes: uncertainty; experiences of support and services; independence and personhood; and cumulative pressures and concerns. We develop this analysis by reviewing how our themes reflect, extend, or depart from previously identified markers of precarity and consider the specific ways in which these markers shape the lives of those living with dementia.

The associations between personality traits and quality of life, satisfaction with life, and well-being over time in people with dementia and their caregivers: findings from the IDEAL programme

BACKGROUND

Cross-sectional evidence indicates that certain personality traits may influence how well people with dementia and their caregivers are able to live alongside the condition. However, no studies to date have explored these associations longitudinally. The present study aimed to explore whether each of the Five-Factor personality traits were associated with change over two years in perceptions of 'living well' for people with dementia and their caregivers. 'Living well' was conceptualized as a composite of quality of life, satisfaction with life, and subjective well-being.

METHODS

Data were analyzed from 1487 people with dementia and 1234 caregivers who took part in the IDEAL cohort. Participants were categorized into low, medium, and high groups for each trait using stanine scores. Latent growth curve models investigated associations between these groups and 'living well' scores for each trait at baseline and at 12 and 24 months. Covariates included cognition in people with dementia and stress in caregivers. A Reliable Change Index was calculated against which to evaluate changes in 'living well' scores over time.

RESULTS

At baseline, neuroticism was negatively associated with 'living well' scores for people with dementia, while conscientiousness, extraversion, openness, and agreeableness were positively associated. For caregivers, neuroticism was negatively associated with 'living well' scores at baseline while conscientiousness and extraversion were positively associated. 'Living well' scores were mostly stable over time with no influence of personality traits on observed changes.

CONCLUSIONS

Findings suggest that personality traits, particularly neuroticism, have a meaningful impact on how people with dementia and caregivers rate their capability to 'live well' at baseline. Over time 'living well' scores for each personality trait group were largely stable. Studies utilizing longer follow-up periods and more appropriate measures of personality are needed to corroborate and extend the findings of the present study.
