Acculturation level and caregiver outcomes from a randomized intervention trial to enhance caregivers' health: evidence from REACH II

Evaluating the Efficacy of Time for Living and Caring: An Online Intervention to Support Dementia Caregivers' Use of Respite

Background and Objectives

Respite, defined as time away from caregiving, is the most requested type of caregiver support. Time for Living and Caring (TLC) is a virtual coaching "app" that helps caregivers schedule and plan their respite time-use. The objectives of this analysis are: (1) to assess the efficacy of the TLC intervention on respite time-use and on caregiver well-being and (2) to identify the key features of the intervention that serve as the likely mechanism of action.

Research Design and Methods

A sample of dementia caregivers (n = 163, 79% female, 84% White, 6% Hispanic, average age 62) were randomized into one of two intervention delivery methods. Intervention efficacy was evaluated using pre/post-comparisons of respite time-use and an additive "dosing" model that estimated unique parameters associated with the exposure to each specific intervention component.

Results

Both immediate and delayed-attention groups reported increased respite time. They also improved in their ability to plan and perceive benefit from their respite time-use over the 16-week intervention period. At 8 weeks, the immediate group did not change in anxiety, whereas the delayed group worsened (p < .001). At 16 weeks, the groups were similar in their anxiety levels. By the 20-week follow-up period, when neither group had access to TLC, both experienced an increase in anxiety.

Discussion and Implications

TLC is a promising intervention that may support caregivers' well-being, by helping them schedule and plan their respite to maximize its benefit. The provision of weekly coaching seems to be the intervention component (mechanism) associated with caregiver outcomes.

Relationship Between Acculturation and Mental Health in Korean American Family Caregivers of Community-Dwelling Persons Living with Dementia

Despite the growing number of Korean American (KA) family caregivers for persons with dementia, little is known about how acculturation might affect caregiving stress in this population. Acculturation is a variable of considerable interest in caregiving research due to its significance in understanding the impact of cultural perceptions and expectations on the caregiving role and its relation to mental health outcomes. A cross-sectional descriptive study using baseline data from an ongoing randomized controlled trial of dementia caregiver intervention was performed to examine the association between acculturation and mental health outcomes among KA caregivers (n = 32) for persons with dementia. Self-report survey questionnaires including a bidirectional acculturation scale, Center for Epidemiologic Studies Depression Scale, the Perceived Stress Scale, and the Zarit Burden Interview were administered in person in English or Korean by trained bilingual community health workers. The primary independent variable, acculturation, was assessed using a 24-item inventory. It measured two sets of cultural orientation: Korean orientation and American orientation. The mean age was 67 years (SD = 11.8) and 87% were women. Half of the caregivers were spouses of persons with dementia, while the other half were offspring caregivers. In the multiple linear regression model, caregiver acculturation toward Korean cultural orientation had a significant and positive association with depressive symptoms (β = .62; SE = 0.25; p-value = .02) and perceived stress (β = .29; SE = 0.13; p-value = .03) after adjusting for age and self-efficacy. No significant effect of American cultural orientation was found for caregiver burden, perceived stress, or depressive symptoms. Our findings suggest that exploring the role of acculturation in caregiving and its relation to outcomes, particularly caregiver distress, may be valuable for future studies aiming to understand specific elements of cultural values and practices in the acculturation process related to mental health outcomes among immigrant Korean American caregivers.

Maximizing the Benefit of Respite for Dementia Caregivers: A Study Protocol Describing the Development & Evaluation of the Time for Living & Caring (TLC) Intervention

Dementia caregivers are susceptible to adverse physical and mental health outcomes, given the often prolonged and challenging care and support they provide to family members with Alzheimer's Disease and Related Dementias (ADRD). This report describes a community-engaged implementation of a novel behavioral intervention - an "app" (interactive website) called TLC (Time for Living and Caring) that coaches caregivers on how to maximize the benefits associated with respite time. The rationale and features of the TLC intervention and the full research protocol used to develop and then evaluate its feasibility, acceptability, and initial efficacy are described here.

Intersection of multiple factors shape Korean American caregiver experience in dementia caregiving

BACKGROUND AND OBJECTIVES

Studies have shown that cultural norms such as filial responsibility and familism operate in the Korean American caregiving context. The purpose of our study is to understand the practice of Korean American caregivers who provide care to a family member living with dementia and their dementia care support needs.

MATERIALS AND METHODS

We conducted 2 focus groups and individual semi-structured interviews with a total of 20 Korean American caregivers. We used inductive thematic analysis to guide coding and generation of themes.

RESULTS

Three themes were identified; 1) intersectionality in the Korean American caregiver experience, 2) complex family dynamics, and 3) dementia care barriers and caregiver support needs. Within the dyadic relationship and the family, cultural identity, generational, acculturational, and language factors shaped the caregiver experience. The need to navigate bicultural norms could lead to tensions but also provide opportunity for caregivers to consider self-care and use external supports to decrease the work of caregiving. Family was the unit of caregiving and caregiving was divided among family members based on acculturation and language fluency. Caregivers desired both medical information combined with knowledge that experienced lay support could provide. Support that reflects their cultural context was valued.

DISCUSSION

Findings suggest the importance of understanding the diversity of response to strong elder care norms among Korean American caregivers and the intersection of multiple factors that influence their caregiving experience. Integrating acculturation and generational assessments may be useful as a way to tailor interventions to optimize engagement in dementia care interventions.

Comprehensive Understanding of Hispanic Caregivers: Focus on Innovative Methods and Validations

Alzheimer’s disease (AD) and Alzheimer’s disease-related disorders (ADRD) are late-onset, age-related progressive neurodegenerative disorders, characterized by memory loss and multiple cognitive impairments. Current research indicates that Hispanic Americans are at an increased risk for AD/ADRD and other chronic conditions such as diabetes, obesity, hypertension, and kidney disease, and given their rapid growth in numbers, this may contribute to a greater incidence of these disorders. This is particularly true for the state of Texas, where Hispanics are the largest group of ethnic minorities. Currently, AD/ADRD patients are taken care by family caregivers, which puts a tremendous burden on family caregivers who are usually older themselves. The management of disease and providing necessary/timely support for patients with AD/ADRD is a challenging task. Family caregivers support these individuals in completing basic physical needs, maintaining a safe living environment, and providing necessary planning for healthcare needs and end-of-life decisions for the remainder of the patient’s lifetime. Family caregivers are mostly over 50 years of age and provide all-day care for individuals with AD/ADRD, while also managing their health. This takes a significant toll on the caregiver’s own physiological, mental, behavioral, and social health, in addition to low economic status. The purpose of our article is to assess the status of Hispanic caregivers. We also focused on effective interventions for family caregivers of persons with AD/ADRD involving both educational and psychotherapeutic components, and a group format further enhances effectiveness. Our article discusses innovative methods and validations to support Hispanic family caregivers in rural West Texas.

Non-Pharmacologic Interventions for Hispanic Caregivers of Persons with Dementia: Systematic Review and Meta-Analysis

Background: As the Hispanic/Latino (HL) population grows, so too does the need for HL family caregivers for persons with dementia. HL caregivers tend to have less education, lower health literacy, and lower income, each uniquely compounding burden. Research is needed to appropriately tailor interventions for this population. Objective: A systematic review and meta-analysis was conducted to 1) provide an updated review of non-pharmacologic intervention studies for HL dementia caregivers, 2) characterize promising interventions, and 3) highlight opportunities for future research. Methods: Databases were searched for articles evaluating non-pharmacologic interventions for HL dementia caregivers. Studies were excluded if target populations did not include HLs or if no intervention was delivered. Data were extracted and random effects meta-analysis was performed on two primary outcomes: caregiver depression and burden. Effect sizes were calculated as pre- and post-intervention standardized mean differences (SMD), and further depression subgroup meta-analysis was performed. Other secondary outcome measures (e.g., perceived social support, caregiver knowledge, anxiety) were evaluated qualitatively. Results: Twenty-three studies were identified. Most included multiple components pertaining to psychosocial support, caregiver education, and community resource facilitation. Many studies were successful in improving caregiver outcomes, though intervention design varied. Meta-analysis revealed minimal to moderate heterogeneity and small effect size in improving depressive symptoms (SMD = –0.31, 95% CI –0.46 to –0.16; I2 = 50.16%) and burden (SMD = –0.28, 95% CI –0.37 to –0.18; I2 = 11.06%). Conclusion: Although intervention components varied, many reported outcome improvements. Future studies may benefit from targeting physical health, addressing sociocultural and economic contexts of caregivers, and leveraging technology.

A cultural approach to dementia - insights from US Latino and other minoritized groups

Alzheimer disease and related dementias present considerable challenges to health-care and medical systems worldwide. In the USA, older Black and Latino individuals are more likely than older white individuals to have Alzheimer disease and related dementias. In this Perspective, we leverage our experience and expertise with older US Latino groups to review and discuss the need to integrate cultural factors into dementia research and care. We examine the importance of considering the effects of cultural factors on clinical presentation and diagnosis, dementia risk, clinical research and recruitment, and caregiving practices, with a focus on minoritized groups in the USA. We highlight critical gaps in the literature to stimulate future research aimed at improving the prevention and early detection of Alzheimer disease and related dementias and developing novel treatments and interventions across ethnoracially diverse populations. In addition, we briefly discuss some of our own initiatives to promote research and clinical care among Latino populations living in the USA.

Segmented assimilation as a mechanism to explain the dietary acculturation paradox

Latinos have disproportionately high rates of diet-related diseases which are associated with acculturation to the U.S. This negative shift in dietary quality is paradoxical in light of gains in income and education that would be expected to lead to better diet. We examined the extent to which the dietary acculturation paradox among Mexican Americans can be explained by segmented assimilation, a theory that considers how immigrants' and their descendants' trajectories of integration are influenced by a complex interplay of individual, social, and structural factors. First, we performed confirmatory cluster analysis to identify three assimilation segments (classic, underclass, and selective) based on education, income, and an acculturation proxy derived from language, nativity, and time in the U.S. among Mexican-origin participants (N = 4475) of the 2007-2016 National Health and Nutrition Examination Survey (NHANES). These segments were then used as independent variables in linear regression models to estimate the relationship between cluster and dietary quality (assessed by the Health Eating Index (HEI)) and the interaction between cluster and gender, controlling for marital status. There were strong effects of cluster on dietary quality, consistent with hypotheses per segmented assimilation theory. The classic assimilation segment had the poorest diet, despite having higher income and education than the underclass segment. The selective segment had higher or similar dietary quality to the underclass segment. Consistent with expectations, this difference was driven by the relatively higher consumption of greens and beans and whole grains of those in the selective and underclass segments. Overall, women had better diets than men; however, the strongest gender contrast was in the underclass segment. This study advances understanding of dietary acculturation and potential disparities in diet-related health outcomes.

Bilingual problem-solving training for caregivers of adults with dementia: A randomized, factorial-design protocol for the CaDeS trial

OBJECTIVE

Caregivers of individuals with Alzheimer's disease and related dementias (ADRD) often experience debilitating caregiver burden and emotional distress. To address these negative emotional consequences of caregiving, we will test and refine a strategy training intervention - Problem-Solving Training (PST) - that promotes self-efficacy and reduces caregiver burden and depressive symptoms. Previous research supports efficacy of PST; however, we do not know exactly how many PST sessions are needed or if post-training "boosters" are required to maintain PST benefits. Additionally, we translated and culturally-adapted PST into "Descubriendo Soluciones Juntos" (DSJ), our novel intervention for Spanish-speaking caregivers.

METHOD

In this 2 × 2 factorial design randomized controlled trial, we will test remotely-delivered PST/DSJ sessions for both English- and Spanish-speaking caregivers of persons with ADRD to determine the optimal number of PST/DSJ sessions and ongoing "booster" sessions needed to best help caregivers navigate their current and future needs.

AIMS

1) Compare the efficacy of three vs. six PST/DSJ sessions each with and without booster sessions for decreasing caregiver burden and depression and enhancing caregiver problem-solving; 2) Identify key factors associated with efficacy of PST/DSJ, including age, gender, primary language, relationship to care recipient, and uptake of the PST/DSJ strategy.

RESULTS

These results will establish guidelines needed for an evidence-based, culturally-adapted, and implementable problem-solving intervention to reduce caregiver stress and burden and improve caregiver health and well-being.

CONCLUSION

This work promotes inclusion of diverse and underserved populations and advances therapeutic behavioral interventions that improve the lives of caregivers of individuals with chronic conditions.

Development of multi-component counseling program for enhancing resilience among Thai caregivers of older persons with dementia

Purpose

The purpose of this study was to develop a multi-component counseling program and examine the short-term effects of an 8-session program.

Design/methodology/approach

This present study was a research and development of a multi-component counseling program for enhancing resilience. The concept of resilience was reviewed based on a synthesis of existing research, together with an exploration of qualitative data derived from an interview with ten caregivers of older persons with dementia. Six domains of resilience were identified: physical, relationships, emotional, moral, cognitive and spiritual; which were then used to develop the eight-week program. The program was examined by a panel of three experts for content validity, which yielded an index of 0.87. The program was then tried out with 60 caregivers recruited and assigned 30 caregivers in the intervention and control group. The Caregiver’s Resilience Scale (CRS) was used by trained nurses to evaluate the program and data were analyzed using repeated measures ANOVA.

Findings

The results indicated that the resilience scores of the participants in the intervention group were statistically significantly higher than those of the control group at one month after program participation and at the follow-up three months later (p < 0.05).

Originality/value

It could be concluded that the program yielded support for the evidence-based practice of non-pharmacological intervention. The program would be suitable as a clinical practice guideline to provide help to caregivers of older persons with dementia at the outpatient setting.

A Mobile App-Based Intervention Program for Nonprofessional Caregivers to Promote Positive Mental Health: Randomized Controlled Trial

BACKGROUND

While nonprofessional caregivers often experience a sense of fulfillment when they provide care, there is also a significant risk of emotional and physical burnout. Consequently, this can negatively affect both the caregiver and the person being cared for. Intervention programs can help empower nonprofessional caregivers of people with chronic diseases and develop solutions to decrease the physical and psychological consequences resulting from caregiving. However, most clinically tested intervention programs for nonprofessional caregivers require face-to-face training, and many caregivers encounter obstacles that hinder their participation in such programs. Consequently, it is necessary to design internet-based intervention programs for nonprofessional caregivers that address their needs and test the efficacy of the programs.

OBJECTIVE

The aim of this study was to evaluate the effectiveness of a smartphone app-based intervention program to increase positive mental health for nonprofessional caregivers.

METHODS

This study was a randomized controlled trial of 3 months' duration. A total of 152 caregivers over 18 years of age with a minimum of 4 months' experience as nonprofessional caregivers were recruited from primary health care institutions. Nonprofessional caregivers were randomized into two groups. In the intervention group, each caregiver installed a smartphone app and used it for 28 days. This app offered them daily activities that were based on 10 recommendations to promote positive mental health. The level of positive mental health, measured using the Positive Mental Health Questionnaire (PMHQ), and caregiver burden, measured using the 7-item short-form version of the Zarit Caregiver Burden Interview (ZBI-7), were the primary outcomes. Users' satisfaction was also measured.

RESULTS

In all, 113 caregivers completed the study. After the first month of the intervention, only one factor of the PMHQ, F1-Personal satisfaction, showed a significant difference between the groups, but it was not clinically relevant (0.96; P=.03). However, the intervention group obtained a higher mean change for the overall PMHQ score (mean change between groups: 1.40; P=.24). The results after the third month of the intervention showed an increment of PMHQ scores. The mean difference of change in the PMHQ score showed a significant difference between the groups (11.43; P<.001; d=0.82). Significant changes were reported in 5 of the 6 factors, especially F5-Problem solving and self-actualization (5.69; P<.001; d=0.71), F2-Prosocial attitude (2.47; P<.001; d=1.18), and F3-Self-control (0.76; P=.03; d=0.50). The results of the ZBI-7 showed a decrease in caregiver burden in the intervention group, although the results were inconclusive. Approximately 93.9% (46/49) of the app users indicated that they would recommend the app to other caregivers and 56.3% (27/49) agreed that an extension of the program's duration would be beneficial.

CONCLUSIONS

The app-based intervention program analyzed in this study was effective in promoting positive mental health and decreasing the burden of caregivers and achieved a high range of user satisfaction. This study provides evidence that mobile phone app-based intervention programs may be useful tools for increasing nonprofessional caregivers' well-being. The assessment of the effectiveness of intervention programs through clinical trials should be a focus to promote internet-based programs in health policies.

A Pilot Study on the Efficacy of Stress Relief Programs for Family Caregivers of Older People with Dementia

The aim of this study was to evaluate the effects of stress-relief programs on positive aspects of caregiving and depression among caregivers of older people with dementia. A quasi-experimental design was employed. Participants in the experimental group received a 8-week period and 120 minutes each session cognitive-behavioral therapy. Participants in the control group received standard health education. Stress relief programs may alleviate depression and increase positive aspects of caregiving among family caregivers of older people with dementia. These findings will help health professionals to implement stress-relief strategies for family caregivers of older people with dementia, or to use those strategies to increase positive aspects of caregiving, or to alleviate depression in caregivers.

Sense of Filial Obligation and Caregiving Burdens Among Chinese Immigrants in the United States

BACKGROUND/OBJECTIVES

Focusing on Chinese immigrants, this study examined (1) whether filial obligation, the core social norm in the Chinese culture, is related to caregiving burdens; and (2) whether level of acculturation of the caregivers moderates the above relationships.

DESIGN

Cross-sectional.

SETTING

Chicago, Illinois.

PARTICIPANTS

A purposive sample of 393 Chinese adult immigrants who were primary caregivers of parents aged 60 years or older.

MEASURES

Sense of filial obligation was captured by felt responsibility toward parents in six domains (respect, make happy, care, greet, obey, and provide financial support). Caregiving burdens were measured by the Caregiver Burden Inventory. Acculturation was measured by 12 questions about respondents' language preference in different settings and ethnicity of individuals they interact with.

RESULTS

A stronger sense of filial obligation was significantly associated with lower levels of developmental (β = -.15), emotional (β = -.18), social (β = -.20), and physical (β = -.10) burdens. For subjective burdens (developmental, social burdens), such a protective effect of filial obligation was stronger among caregivers with lower acculturation levels. For more objective burdens (time-dependent, physical burdens), stronger filial obligation was actually associated with greater burdens among caregivers with higher acculturation levels.

CONCLUSION

Programs focusing on celebrating the cultural heritage of immigrants and improving the relationship between the parents and children may be helpful to reduce caregiving burdens. Intervention programs that help Chinese immigrant caregivers to find the most appropriate way to balance traditional and new social norms are important to provide successful care to aging Chinese immigrants.

Sociocultural Factors Influencing Caregiver Appraisals Following Traumatic Brain Injury

OBJECTIVE

To investigate the association of the sociocultural variables race/ethnicity, education, and poverty level to caregivers' positive and negative appraisals following traumatic brain injury.

DESIGN

Survey.

SETTING

Community.

PARTICIPANTS

Caregivers (N=344; 216 white; 69 black; 39 Hispanic) of persons with complicated mild to severe TBI at least 1-year postinjury.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Modified Caregiver Appraisal Scale (M-CAS); Zarit Burden Interview (ZBI).

RESULTS

Black caregivers reported lower levels of perceived burden on both the M-CAS and the ZBI. Black and Hispanic caregivers reported more traditional caregiver ideology (caregiving as a responsibility) than did whites. Greater poverty was associated with higher burden on the M-CAS, lower caregiver satisfaction, and less mastery. Higher education was associated with higher burden on the ZBI and with lower caregiver mastery.

CONCLUSIONS

Treatment professionals should be culturally sensitive to the different perspectives that caregivers may have based on sociocultural factors. Sociocultural factors should be considered in research investigating caregiver outcomes, including appraisals.

Nutrition Label Use and Its Association With Dietary Quality Among Latinos: The Roles of Poverty and Acculturation

OBJECTIVE

To investigate how acculturation and poverty are independently and jointly associated with the use of the Nutrition Facts panel (nutrition label) and to examine the extent to which nutrition label use moderates the association of poverty and acculturation on dietary quality among Latinos.

DESIGN

Cross-sectional analysis of the 2007/2008 and 2009/2010 waves of the National Health and Nutrition Examination Survey.

PARTICIPANTS

A total of 3,696 adults (aged >19 years) self-identified as Latino/Hispanic with food label use data from the most recent Consumer Behavior Phone Follow-Up Modules.

MAIN OUTCOME MEASURE(S)

Nutrition label use and dietary quality.

ANALYSIS

Logistic regression.

RESULTS

Acculturation moderated the association of income on the likelihood of using nutrition labels, such that lower-income English-speaking Latinos were half as likely as higher-income English-speakers to use nutrition labels (P = .01, odds ratio [OR] = 0.44, 95% confidence interval [CI], 0.24-0.81); however, Spanish speakers were equally likely to use nutrition labels across income levels (P = .99; OR = 1.00; 95% CI, 0.77-1.31). Nutrition label use moderated the association of acculturation on diet. Among English-speaking Latinos, those who read nutrition labels had less than half the risk for poor diet (P =.001; OR = 0.43; 95% CI, 0.26-0.69); however, label use was not significantly associated with the diet quality of Spanish speakers (P = .07; OR = 0.82; 95% CI, 0.67-1.02). Nutrition label use decreased the risk for poor dietary quality regardless of poverty status.

CONCLUSIONS AND IMPLICATIONS

Overall, results demonstrated a positive association between the use of the Nutrition Facts panel for Latinos and dietary quality. An important nutrition education strategy among bicultural Latinos at risk for a poor diet as a result of acculturation may include label reading comprehension. This approach may also address the low rates of label use. The study provides evidence of segmented assimilation in which low-income, bicultural Latinos follow an underclass pattern of acculturation demonstrated by a lower likelihood of reading nutrition labels and higher-income, bicultural Latinos follow the more successful selective pattern.
