Effects of a Modified Mindfulness-Based Cognitive Therapy for Family Caregivers of People With Dementia: A Randomized Clinical Trial

Effectiveness of a health education program for people with dementia and their family caregivers: An intervention by nurse practitioners

PURPOSE

This study assesses the effectiveness of a health education program on caregiving outcomes for people with dementia and their families.

METHODS

This quasi-experimental study involved 250 people with dementia and their family caregivers. Behavioral problems in people with dementia were assessed using the Chinese version of the Cohen-Mansfield Agitation Inventory-community form. Family caregiver outcomes were measured using the Agitation Management Self-Efficacy Scale, Caregiver Preparedness Scale, Competence Scale, and Community Resource Awareness and Utilization Assessment.

RESULTS

Following the intervention, the experimental group demonstrated significant improvements in terms of self-efficacy, preparedness, competence, and awareness and utilization of community resources among family caregivers. Additionally, the experimental group exhibited lower levels of behavioral problems among people with dementia.

CONCLUSIONS

This study helped improve caregiving outcomes for people with dementia and their family caregivers. Therefore, outpatient healthcare providers can utilize these findings to enhance care for this population.

A meta-analysis of mindfulness-based interventions for improving mental health and burden among caregivers of persons living with dementia

BACKGROUND

Mindfulness-based interventions are becoming increasingly popular and are effective in lowering depressive symptoms and caregiver burden. However, the overall efficacy of therapies in stress and anxiety management is unreported, and no study to date has performed a subgroup analysis to investigate the intervention dose response of outcomes.

AIMS

To quantitatively identify the effectiveness of mindfulness-based interventions for caregivers of persons living with dementia.

METHODS

A comprehensive literature search of six databases was undertaken from the date of inception to June 18, 2023. The DerSimonian-Laird model with random effects was used to examine the overall effect and its heterogeneity in the studies. Version 2 of the risk of bias (RoB 2) tool was employed to analyze the publication bias of each randomized study. Funnel and forest plots were created to represent the findings.

RESULTS

Thirteen randomized trials were included in the meta-analysis. Mindfulness-based interventions significantly reduced stress and anxiety of caregivers of persons living with dementia. In addition, interventions provided for ≥8 weeks were beneficial in reducing depression in caregivers. However, mindfulness-based interventions did not offer significant benefits in reducing depression or caregiver burden immediately after the intervention.

CONCLUSION

Mindfulness-based interventions have the potential to help caregivers of people living with dementia. This study could be used as a model for future research into and implementation of mindfulness-based therapies for caregivers.

LINKING EVIDENCE TO ACTION

Mindfulness-based therapies appear to alleviate stress and anxiety but are ineffective in reducing depression and burden in caregivers of persons living with dementia. Well-designed RCTs with more rigorous methodology and a larger sample size should be conducted to firm the conclusion of the effectiveness of mindfulness-based interventions for caregivers of persons living with dementia.

The effect of mindfulness-based interventions on mental health outcomes and wellbeing of informal caregivers of people with mental illness: A systematic review and meta-analysis

The increasing prevalence of mental illness has resulted in a growing burden on informal caregivers. Mindfulness-based interventions, as a form of psychotherapy, have shown efficacy in alleviating psychological stress and enhancing emotional and physical well-being. However, the utilisation of mindfulness-based interventions for informal caregivers of individuals with mental illness remains limited. The aim of the meta-analysis is to evaluate the impact of mindfulness-based interventions on the mental health and well-being among informal caregivers of people with mental illness. A comprehensive literature search was conducted across seven electronic databases (PubMed, Scopus, Web of Science, Cochrane Library, Embase, APA PsycINFO and CINAHL Ultimate) from the inception of these databases until 20 July 2023. Two authors independently screened the studies and extracted the relevant data. The meta-analysis was performed by using Stata 12.0 software, and the effect sizes were calculated utilising standardised mean difference (SMD) along with their corresponding 95% confidence intervals (CI). The meta-analysis included 13 studies with 1007 participants, and the results demonstrated that mindfulness-based interventions were efficacious in reducing stress (SMD = -0.80, 95% CI [-1.33, -0.28], p = 0.003), depression (SMD = -0.43, 95% CI [-0.62, -0.24], p < 0.001) and caregiver burden (SMD = -0.21, 95% CI [-0.40, -0.01], p = 0.038), and enhancing the mindfulness level (SMD = 0.37, 95% CI [0.09, 0.65], P = 0.010) and quality of life (SMD = 0.22, 95% CI [0.04, 0.39], p = 0.015) among informal caregivers of people with mental illness, but not on anxiety reduction (SMD = -0.19, 95% CI [-0.49, 0.10], p = 0.198). Furthermore, future research should aim to employ more rigorous methodologies to confirm the effectiveness.

Multiphase optimization of a multicomponent intervention for informal dementia caregivers: a study protocol

BACKGROUND

Family caregiver interventions are essential to support dementia caregiving. However, such interventions are typically complex and consist of multiple components. Existing evidence rarely delineates the effectiveness and interactions between individual components. To optimise intervention, we adopt the multiphase optimisation strategy (MOST) to test the implementation fidelity and determine the effect of each component and the interactions between each component and the corresponding outcome.

METHODS

A prospective, assessor-blinded, randomised clinical trial with fractional factorial design using the MOST principle. Two hundred fifty family dementia caregivers will be randomised to one of 16 experimental conditions in a fractional factorial design involving six intervention components: (1) dementia and caregiving education; (2) self-care skills; (3) behavioural symptom management; (4) behavioural activation; (5) modified mindfulness-based cognitive therapy; and (6) support group. The first one is the core component, and the five remaining will be examined. Physical health, caregiver burden, stress, psychological well-being, anxiety and depressive symptoms, and social support will be assessed over the 12-month study period. Following the intention-to-treat principle, linear mixed models and regression analyses will be used to examine the specific effect of the five components and their two-way interactions to propose the most effective combination.

DISCUSSION

This is the first study adopting the multiphase optimisation strategy to identify the most active and engaging components of a psychological intervention for caregivers of patients with dementia. In view that dementia caregiver interventions are increasingly diversified and complex, such knowledge is important to maximise the intervention efficacy and allow the intervention to be implemented within an efficient timeframe and dosage. The optimisation of caregiver support interventions is critical to enhance the health outcomes of caregivers and care recipients, thereby, delaying possible institutionalisation and reducing the costs of long-term dementia care.

Reducing fear and avoidance of memory loss improves mood and social engagement in community-based older adults: a randomized trial

BACKGROUND

Alzheimer's disease and related dementias (ADRD) are among the most feared age-related conditions. The aim of this study was to evaluate a brief psychological intervention to promote adaptive coping in older adults experiencing heightened fear of ADRD and investigate positive downstream effects on health-related secondary outcomes, including frequency of reported memory failures, psychosocial functioning, and quality of life.

METHODS

Eighty-one older adults were recruited and randomized into REFRAME or active control intervention arms. Both groups received psycho-education and training in mindful monitoring of fears related to ADRD. The REFRAME group received an additional behavioral activation component intended to disrupt maladaptive avoidant coping (i.e., avoidance) strategies. Both groups completed 3-weeks of intervention exercises with accompanying questionnaires (baseline, mid- and post-intervention and 4-week follow-up).

RESULTS

Adherence was strong (> 75%). We observed a significant reduction in ADRD-related fear and avoidance in both groups. Significant reductions were also observed for frequency of self-reported memory failures, anxiety, and depression. Depression was significantly reduced in the REFRAME group compared to the control group. Significant increases in participants' ability to participate in social activities and well-being were also observed.

CONCLUSIONS

Findings suggest that a brief psychological intervention can mitigate ADRD-related fears and avoidant coping in older adults, and that benefits extend to broader health-related outcomes including anxiety, depression, social functioning, and well-being. Addressing ADRD-related fear has implications for healthy aging and risk reduction, as individuals may be more likely to engage in activities that are protective against ADRD but were previously avoided.

Integrative Stress Reduction Program for Family Caregivers of Persons With Advanced Dementia: A Randomized-Controlled Trial

BACKGROUND

Older adults with advanced dementia require significant care, leading to high stress levels in caregivers.

OBJECTIVES

The current study aimed to evaluate the effects of an Integrative Stress Reduction Program on Thai caregiver's outcomes of stress, sleep quality, and caregiver-assessed neuropsychiatric symptoms of persons with dementia.

METHODS

A single-blind randomized-controlled trial was conducted. A sample of family caregivers of people with dementia was recruited from memory clinics at outpatient community health centers in Thailand and randomly assigned to the experimental and control groups. Participants in the experimental group were enrolled in 5 intervention sessions over 4 weeks, while the control group received usual care. Outcome variables were collected at baseline, 4 weeks postintervention, and 8 weeks of follow-up.

RESULTS

Compared with the control group, caregivers in the experimental group (n = 27) had significantly decreased stress (p < .01) and better sleep quality (p < .01), and caregivers reported that their family members with dementia (n = 27) had decreased neuropsychiatric symptoms (p < .01) after the intervention (week 4) and at the 8-week follow-up.

CONCLUSIONS

The Integrative Stress Reduction Program improved outcomes for caregivers and decreased neuropsychiatric symptoms in people with dementia.

Effects of a Social Media-Based Mind-Body Intervention Embedded With Acupressure and Mindfulness for Stress Reduction Among Family Caregivers of Frail Older Adults: Pilot Randomized Controlled Trial

BACKGROUND

Family caregivers of frail older adults experience high levels of stress. Mind-body interventions (MBIs) focused on caregiver stress are often limited in teaching approaches, difficult to practice, and costly. A social media-based MBI embedded with mindfulness meditation (MM) and self-administered acupressure (SA) may be effective for family caregivers, offer greater usability, and lead to greater adherence.

OBJECTIVE

The aim of this study was to test the feasibility and preliminary effects of a social media-based MBI embedded with MM and SA on family caregivers of frail older adults and to investigate the preliminary effects of the intervention using a pilot randomized controlled trial.

METHODS

A 2-arm randomized controlled trial design was adopted. Family caregivers of frail older adults (n=64) were randomized into either the intervention group (n=32), receiving 8 weeks of social media-based MM and SA, or the control group (n=32), receiving brief education on caregiving for people with frailty. The primary outcome (caregiver stress) and secondary outcomes (caregiver burden, sleep quality, and mindfulness awareness and attention) were measured using a web-based survey at baseline (T0), immediately after the intervention (T1), and at the 3-month follow-up (T2).

RESULTS

The feasibility of the intervention was established with a high attendance rate (87.5%), high usability score (79), and low attrition rate (1.6%). The generalized estimating equation results showed that participants in the intervention group at T1 and T2 experienced a significant improvement in stress reduction (P=.02 and P=.04, respectively), sleep quality (P=.004 and P=.01, respectively), and mindful awareness and attention (P=.006 and P=.02, respectively) compared with the control group. There were no substantial improvements in caregiver burden at T1 and T2 (P=.59 and P=.47, respectively). A focus group session conducted after the intervention had 5 themes: impact on the family caregivers, difficulty in practicing the intervention, the strength of the program, the limitations of the program, and perception of the intervention.

CONCLUSIONS

The findings support the feasibility and preliminary effects of social media-based MBI embedded with acupressure and MM on reducing stress among family caregivers of frail older people and enhancing sleep quality and mindfulness levels. A future study with a larger and more diverse sample is proposed to evaluate the longer-term effects and generalizability of the intervention.

An Integrative Stress Reduction Program for Family Caregivers of Persons With Advanced Dementia: A Pilot Study

The current study sought to pilot test and examine the effects of an integrative stress reduction program (ISRP) on caregiver stress and sleep quality and behavioral and psychological symptoms of dementia (BPSD) of care recipients. Family caregivers (N = 12) of persons with moderate to severe dementia were recruited from memory clinics in Thailand. Twelve caregivers participated in five educational sessions on dementia care, stress, and BPSD management over 4 weeks. The Relative Stress Scale and Pittsburgh Sleep Quality Index were used to measure caregiver outcomes. The Neuropsychiatric Inventory was used to measure BPSD of care recipients. Outcome variables were collected at baseline, postintervention, and follow up. Data were analyzed using one-way repeated measures analysis of variance. Participants reported statistically decreased stress, improved sleep quality, and decreased BPSD among care recipients postintervention and at follow up (all p < 0.001). The ISRP was feasible and shows promise in reducing stress and improving sleep quality in caregivers and lessening BPSD in care recipients. [Journal of Gerontological Nursing, 48(10), 26-32.].

A 'good dyadic relationship' between older couples with one having mild cognitive impairment: a Q-methodology

BACKGROUND

Cognitive impairment gradually brings changes to the relationship between older married couples. Therefore, this study aimed to understand the individual viewpoints of couple dyads on the important attributes of a 'good dyadic relationship' in the context of mild cognitive impairment (MCI), and to explore if the congruencies and discrepancies in their perceptions related to the quality and closeness of their relationship and well-being.

METHODS

Q-methodology was used to reveal the perceptions of a 'good dyadic relationship' among couples with one having MCI. The participating couples were separated in two rooms and independently ranked 18 relationship attributes from least to most important on a 7-point Q-sort response grid. All participants also completed a post-sort interview and surveys to assess their psychological well-being and closeness. Q-sorts were analyzed using by-person factor analysis.

RESULTS

Forty people with MCI and forty spousal partners completed the Q-sort. Three viewpoints, accounting for 48% of the total variance, were identified and were labeled 'Provider,' 'Problem-solver,' and 'Partner.' Different viewpoints of a 'good dyadic relationship' primarily varied by perceived importance of commitment, dedication, tolerance, and personal space. Despite these differences, there was wide consensus that respecting each other and cherishing the current moment are two universally salient attributes of a good relationship across all viewpoints. Couples with discrepant views scored significantly higher on perceptions of the quality of the relationship and closeness with the partner.

CONCLUSIONS

This study advances the theoretical understanding of the dyadic relationship between couples with one having MCI, from both perspectives. MCI is a state in which couples can openly discuss their expectations. The findings provide practitioners with insights to work with couples experiencing MCI.

The effectiveness of mindfulness-based meditation treatments for late life anxiety: a systematic review of randomized controlled trials

OBJECTIVE

Older adults are interested in mindfulness-based interventions with a meditation component for late life anxiety. This review examined the effectiveness of existing mindfulness-based interventions with a meditation component.

METHODS

This systematic review was registered with the Joanna Briggs Institute on 2021-05-17, was guided by Joanna Briggs Institute methodology and followed the PRISMA framework. Peer-reviewed randomized control trials were reviewed. A systematic literature search was conducted, using the following databases: MEDLINE (Ovid), Embase, Cochrane Database of Systematic Reviews, PsycINFO, CINAHL (EBSCO), and AMED.

RESULTS

Of 2709 studies screened, seven eligible randomized controlled trials were included representing 355 participants. Sample sizes ranged from 36 to 141. Mindfulness-based meditation interventions used varied. Regardless of the mindfulness-based meditation intervention used, a reduction in symptoms of anxiety in participants was reported post-intervention. Results are reported through narrative summary and tables.

CONCLUSIONS

Based on the emerging literature of randomized controlled trials, mindfulness-based interventions with a meditation component appear to be promising in reducing symptoms of anxiety in older adults. These findings demonstrate a need for further randomized controlled trials to guide clinical practice.

Evaluating the effectiveness of a 6-week hybrid mindfulness-based intervention in reducing the stress among caregivers of patients with dementia during COVID-19 pandemic: protocol of a randomized controlled trial

Background

Mindfulness-based intervention (MBI), an emotion-focused approach, has been shown promising and sustainable effects on enhancing the well-being of caregivers of patients with dementia (PWD). However, the conventional MBI was quite demanding, had high rates of attrition and inconsistent long-term effect. The social distancing measures introduced during the COVID-19 pandemic also restricted face-to-face psychosocial intervention. The study aims to evaluate the effectiveness of a 6-week hybrid MBI in caregivers of PWD over a 6-month follow up.

Methods

This is a single-blinded, parallel-group randomized controlled trial (RCT). Eligible participants from three local nongovernmental organizations (NGOs) will be randomly divided into intervention groups and control groups in a ratio of 1:1. The participants in the intervention group will receive 6 weekly 90-min group-based sessions delivered through a face-to-face and online approach. The participants in the control group will receive brief education on dementia care with the same group size, duration, and frequency as the sessions in the intervention group. Immediately after the intervention and at the 6-month follow-up, caring stress and other outcomes will be assessed. Besides, a focus group interview will be conducted to identify the strengths, limitations, and therapeutic components of the intervention from their perspectives. For quantitative data, intention-to-treat analysis and Generalized Estimating Equations (GEE) will be used. For qualitative data, content analysis will be used.

Discussion

This proposed hybrid model of MBI has several advantages, such as lower duration, longer follow-up period and easier access by family caregivers. Also, physiological indicators (e.g., heart rate viability and neuropsychiatric symptoms) will be measured in this study to show the body change after MBI. The quantitative and qualitative data of this research can also benefit the development of online or hybrid MBI for caregivers of PWD during the COVID-19 pandemic. Despite these strengths, it does have practical challenges and limitations. However, this proposed intervention has the potential to benefit not only the participants, but also the researcher as well as public health providers.

Mindfulness-Based Cognitive Therapy for Stress Reduction in Family Carers of People Living with Dementia: A Systematic Review

The prevalence of dementia is increasing and the care needs of people living with dementia are rising. Family carers of people living with dementia are a high-risk group for psychological and physical health comorbidities. Mindfulness-based interventions such as mindfulness-based cognitive therapy show potential for reducing stress experienced by family carers of people living with dementia. This study aims to systematically assess the efficacy of mindfulness-based cognitive therapy in reducing stress experienced by family carers of people living with dementia. Electronic databases including MEDLINE, APA PsycINFO, EMBASE, CINAHL, Scopus, Web of Science, Cochrane Library, AMED, ICTRP, and ALOIS were searched for relevant studies up to August 2020. All types of intervention studies were included. Quantitative findings were explored. Seven studies were eligible for inclusion. The analysis showed that there was a statistically significant reduction in self-rated carer stress in four studies for the mindfulness-based cognitive therapy group compared to controls. One study that was adequately powered also showed reductions in carer burden, depression, and anxiety compared to control. Mindfulness-based cognitive therapy appears to be a potentially effective intervention for family carers of people living with dementia, but large, high-quality randomized controlled trials in ethnically diverse populations are required to evaluate its effectiveness.

Mental and Physical Self-Awareness of Alzheimer Patients: Decreased Awareness of Amnesia and Increased Fear of Falling Compared to Views of Families: The Tajiri and Wakuya Projects

INTRODUCTION

The purpose of this study is to examine self-awareness of patients with Alzheimer disease (AD) regarding forgetfulness and physical status, with the goal of further psychological understanding of these patients.

METHODS

The 255 subjects included 33 healthy volunteers and 48 patients with mild cognitive impairment who were elderly community residents selected from the 2017 Wakuya Project and 174 consecutive outpatients with AD at the Tajiri Clinic. Test data were selected from a pooled database. Results from the Mini-Mental State Examination, Clinical Dementia Rating (CDR), Short Falls Efficacy Scale International (FES), and Everyday Memory Checklist (EMC) were used in the study. FES and EMC data were also obtained from family members for comparison.

RESULTS

EMC scores in the AD groups (mild to moderate and moderate to severe) were significantly higher (more complaining memory impairment) than those in the CDR 0 (healthy) group and significantly lower (less self-awareness for memory impairment) than the corresponding EMC scores of families of the subjects. In contrast, FES scores of the AD groups did not differ significantly from those of the CDR 0 group, and these scores were higher (more fear of falling) than those of family members. Additionally, family-FES scores of the AD groups were higher than those of the CDR 0 and 0.5 groups.

CONCLUSION

The results showed an evidence of the heterogeneity of awareness, an emotional response (concern or fear, FES), and a cognitive appraisal of function (EMC). These may be explained whereby awareness of/fear of falling increases with AD due to a preserved emotional awareness, whereas awareness of cognitive impairment is impaired due to memory deficits.

The Effect of Baseline Patient and Caregiver Mindfulness on Dementia Outcomes

BACKGROUND

Mindfulness is the practice of awareness and living in the present moment without judgment. Mindfulness-based interventions may improve dementia-related outcomes. Before initiating interventions, it would be beneficial to measure baseline mindfulness to understand targets for therapy and its influence on dementia outcomes.

OBJECTIVE

This cross-sectional study examined patient and caregiver mindfulness with patient and caregiver rating scales and patient cognitive performance and determined whether dyadic pairing of mindfulness influences patient outcomes.

METHODS

Individuals (N = 291) underwent comprehensive evaluations, with baseline mindfulness assessed using the 15-item Applied Mindfulness Process Scale (AMPS). Correlation, regression, and mediation models tested relationships between patient and caregiver mindfulness and outcomes.

RESULTS

Patients had a mean AMPS score of 38.0±11.9 and caregivers had a mean AMPS score of 38.9±11.5. Patient mindfulness correlated with activities of daily living, behavior and mood, health-related quality of life, subjective cognitive complaints, and performance on episodic memory and attention tasks. Caregiver mindfulness correlated with preparedness, care confidence, depression, and better patient cognitive performance. Patients in dyads with higher mindfulness had better cognitive performance, less subjective complaints, and higher health-related quality of life (all p-values<0.001). Mindfulness effects on cognition were mediated by physical activity, social engagement, frailty, and vascular risk factors.

CONCLUSION

Higher baseline mindfulness was associated with better patient and caregiver outcomes, particularly when both patients and caregivers had high baseline mindfulness. Understanding the baseline influence of mindfulness on the completion of rating scales and neuropsychological test performance can help develop targeted interventions to improve well-being in patients and their caregivers.
