The effect of psychosocial support on caregivers' perceived criticism and emotional over-involvement of persons with dementia: an assessor-blinded randomized controlled trial

What works to support carers of older people and older carers? an international evidence map of interventions and outcomes

BACKGROUND

Unpaid carers of older people, and older unpaid carers, experience a range of adverse outcomes. Supporting carers should therefore be a public health priority. Our understanding of what works to support carers could be enhanced if future evaluations prioritise under-researched interventions and outcomes. To support this, we aimed to: map evidence about interventions to support carers, and the outcomes evaluated; and identify key gaps in current evidence.

METHODS

Evidence gap map review methods were used. Searches were carried out in three bibliographic databases for quantitative evaluations of carer interventions published in OECD high-income countries between 2013 and 2023. Interventions were eligible if they supported older carers (50 + years) of any aged recipient, or any aged carers of older people (50 + years).

FINDINGS

205 studies reported across 208 publications were included in the evidence map. The majority evaluated the impact of therapeutic and educational interventions on carer burden and carers' mental health. Some studies reported evidence about physical exercise interventions and befriending and peer support for carers, but these considered a limited range of outcomes. Few studies evaluated interventions that focused on delivering financial information and advice, pain management, and physical skills training for carers. Evaluations rarely considered the impact of interventions on carers' physical health, quality of life, and social and financial wellbeing. Very few studies considered whether interventions delivered equitable outcomes.

CONCLUSION

Evidence on what works best to support carers is extensive but limited in scope. A disproportionate focus on mental health and burden outcomes neglects other important areas where carers may need support. Given the impact of caring on carers' physical health, financial and social wellbeing, future research could evaluate interventions that aim to support these outcomes. Appraisal of whether interventions deliver equitable outcomes across diverse carer populations is critical.

Expressed Emotion in Families of People With Dementia: A Review of Scale-Based Measures

PURPOSE

Research on the concept of expressed emotion (EE) has expanded in recent years but its role in dementia still requires elucidation. Understanding the role of EE in the dementia context could help in the development of appropriate interventions.

METHOD

The current review synthesized relevant literature to investigate the prevalence and correlates of EE status in families of people with dementia. A comprehensive search of four databases from inception to 2022 produced 2,683 papers; 18 studies met inclusion criteria.

RESULTS

The use of EE criteria differed not only across cultural contexts, but even within the same cultural context. Overall, the prevalence of EE in families with dementia compared with other psychiatric conditions was not high.

CONCLUSION

Specific changes in EE over time remain to be explored, and findings emphasize the need to carefully discriminate High EE status based on the cultural background of family members with dementia. [Journal of Gerontological Nursing, 50(2), 17-25.].

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.

Which cognitive behavioral therapy delivery formats work for depressive symptoms in dementia caregivers? - A systematic review and network meta-analysis of randomized controlled trials

BACKGROUND

Cognitive behavioral therapy (CBT) has been shown to be effective to improve depressive symptoms by changing their cognitive processes and concepts for dementia caregivers (DCs). However, whether CBT can be effectively delivered in individual, group, telephone-administered, internet, combine formats remains unclear. We aimed to examine the most effective delivery format for CBT via a network meta-analysis (NMA).

METHODS

An exhaustive literature search was conducted based on Pubmed, Embase, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure database, Chinese Biomedical Literature Database, Wan Fang database, and unpublished data. RCTs were identified from their inception to January 15, 2022. We conducted pairwise and NMA to evaluate the relative effectiveness and rank probability (rank P-score) for different CBT delivery formats. A series of analyses and assessments, such as the risk of bias, and GRADE were performed concurrently. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used for abstracting data.

RESULTS

A total of 37 studies were included in our analysis based on a series of rigorous screenings, which comprised 4191 DCs. Compared with controls, internet (SMD = -1.33, confidence interval (CI): -2.18, -0.66, GRADE low), telephone (SMD = -1.29, CI: -1.89, -0.61, GRADE moderate), and individual (SMD = -1.04, CI: -2.01, -0.07, GRADE very low) showed the largest improvement on depressive symptoms, whereas the group and combine delivery formats were not effective. Notably, there were no statistically significant differences between these five delivery formats: internet, telephone, individual, group, and combine. Sensitivity analyses supported the overall findings.

CONCLUSIONS

Our results suggested that internet, telephone, individual CBT delivery formats were effective for reducing depressive symptoms in DCs. Given the limitations of the NMA approach and the number of included studies, the result should be cautiously interpreted. Further RCTs with respect to the CBT based on different delivery formats' effectiveness are needed.

Trajectories of socio-emotional functioning in early-stage dementia: implications for the individual with dementia and their family carer

BACKGROUND AND OBJECTIVES

Changes in socio-emotional functioning in people living with dementia (PLWD) are common; however, little is known about the broader effects these may have on wellbeing. This study examined socio-emotional functioning over time and associations with the wellbeing of PLWD and their family carers.

METHOD

One hundred and one individuals with a diagnosis of dementia and their respective carers completed the Social Emotional Questionnaire (assessing emotion recognition, empathy, social relationships and social behaviour) alongside measures of dementia severity, cognition, mood, stress, and relationship quality. Sixty-six dyads were reassessed on the same measures at 12 months post-baseline, and 51 dyads again at 20 months post-baseline.

RESULTS

When rated by the PLWD, there was no change in socio-emotional functioning over time; however, carers reported a significant decline over time. For both carers and the PLWD, poorer wellbeing measures were indicative of worse socio-emotional functioning at Time 1, though only dementia type, quality of life and relationship quality impacted upon the trajectory of socio-emotional decline over time.

CONCLUSIONS

Changes in social and emotional functioning are evident early in the course of dementia and worsen within 20 months. Both carer characteristics and those of the PWLD affected reporting of social and emotional functioning. These data are useful for guiding the provision of appropriate education and care.

Internet-Based Supportive Interventions for Family Caregivers of People With Dementia: Systematic Review and Meta-Analysis

Background

Caring for people with dementia is perceived as one of the most stressful and difficult forms of caring. Family caregivers always experience high levels of psychological burden and physical strain, so effective and practical support is essential. Internet-based supportive interventions can provide convenient and efficient support and education to potentially reduce the physical and psychological burden associated with providing care.

Objective

This review aimed to (1) assess the efficacy of internet-based supportive interventions in ameliorating health outcomes for family caregivers of people with dementia, and (2) evaluate the potential effects of internet-based supportive intervention access by caregivers on their care recipients.

Methods

An electronic literature search of the PubMed, EMBASE, Web of Science, CINAHL, Cochrane Library, and PsycINFO databases was conducted up to January 2020. Two reviewers (ML and YZ) worked independently to identify randomized controlled trials (RCTs) that met the inclusion criteria and independently extracted data. The quality of the included RCTs was evaluated using the approach recommended by the Cochrane Handbook for Systematic Reviews of Interventions. Standardized mean differences (SMDs) with 95% CIs were applied to calculate the pooled effect sizes.

Results

In total, 17 RCTs met the eligibility criteria and were included in this systematic review. The meta-analysis showed that internet-based supportive interventions significantly ameliorated depressive symptoms (SMD=–0.21; 95% CI –0.31 to –0.10; P<.001), perceived stress (SMD=–0.40; 95% CI –0.55 to –0.24; P<.001), anxiety (SMD=–0.33; 95% CI –0.51 to –0.16; P<.001), and self-efficacy (SMD=0.19; 95% CI 0.05-0.33; P=.007) in dementia caregivers. No significant improvements were found in caregiver burden, coping competence, caregiver reactions to behavioral symptoms, or quality of life. Six studies assessed the unintended effects of internet-based supportive intervention access by caregivers on their care recipients. The results showed that internet-based supportive interventions had potential benefits on the quality of life and neuropsychiatric symptoms in care recipients.

Conclusions

Internet-based supportive interventions are generally effective at ameliorating depressive symptoms, perceived stress, anxiety, and self-efficacy in dementia caregivers and have potential benefits on care recipients. Future studies are encouraged to adopt personalized internet-based supportive interventions to improve the health of family caregivers and their care recipients.
