Personal mastery is associated with reduced sympathetic arousal in stressed Alzheimer caregivers

Examining the potential of VR program Tilt Brush in reducing anxiety

Recent advancement in technology has made virtual reality (VR) more accessible and immersive than ever before, resulting in its increasing utility in various industries. Despite this, VR has remained an underutilised tool within clinical psychology. This study aimed to explore the potential of using VR for therapeutic benefits through examining the level of flow and anxiety-reducing effects of freeform drawing in real life (on paper) versus drawing in VR (using Tilt Brush) via a randomised-controlled trial with 40 participants. State and trait anxiety was measured using the State-Trait Anxiety Inventory, level of flow was measured using the Long Flow State Scale, and level of presence was measured using the iGroup Presence Questionnaire. Overall level of flow was not significantly different between both groups, implying drawing in VR induces as much flow as drawing in real life. Level of flow was positively correlated to level of presence experienced in the VR group (p < .01). Although there was no significant interaction effect, both groups experienced an overall decrease in state anxiety, with the VR group experiencing a significant reduction of state anxiety from pre- to post-test (p < .01).

Longitudinal associations between chronic condition discordance and perceived control among older couples

Chronic health conditions among individuals and their partners may diminish perceived control, particularly when these conditions are highly complex. We considered how chronic condition discordance (i.e., the extent that two or more conditions have nonoverlapping self-management requirements) at the individual level and the couple level (i.e., between spouses) was linked to health-related control and personal mastery across an 8-year period, and whether these links varied by age. The U.S. sample included 879 wives (M = 53.81 years) and husbands (M = 57.19 years) from three waves (2006, 2010, and 2014) of the Health and Retirement Study. Dyadic growth curve models controlled for age, minority status, education, own and partner baseline negative marital quality, and own and partner time-varying depressive symptoms, and number of chronic health conditions. Overall, both individual-level and couple-level degrees of chronic condition discordance were associated with initial levels of and rates of change in perceived control. When wives had greater individual-level discordance, they reported lower initial personal mastery. When husbands had greater individual-level discordance, they reported lower initial health-related control and faster declines in health-related control and personal mastery, and their wives reported faster declines in personal mastery. When there was greater couple-level discordance, wives reported lower initial health-related control. Age moderated the associations between wives' individual-level discordance and their own initial level of health-related control and rate of change in personal mastery. Interventions to improve later-life well-being may be enhanced by targeting increases in perceived control among individuals and couples managing complex patterns of chronic conditions.

Psychometrics of the Pearlin Mastery Scale among Family Caregivers of Older Adults Who Require Assistance in Activities of Daily Living

This study examined the psychometric properties of the seven-item mastery scale among 392 family caregivers of care dependent older adults in a tertiary hospital in Singapore. Item response theory (IRT) analysis and confirmatory factor analysis (CFA) were used to assess the scale's psychometric properties. Construct validity was assessed based on correlations between mastery and caregiver burden, depression, and quality of life. Data from the seven-item mastery scale showed acceptable reliability and model fit while IRT analysis showed that response categories were ordered but reflected poor fit for the two positively worded items. Without these two items, responses on the five-item version showed acceptable model fit and had acceptable reliability and high correlation with those on the seven-item version. Item responses on both the seven- and five-item versions show logical correlations with carer self-report on burden, depression, and quality of life. Further psychometric studies of the seven-item mastery scale are warranted. For practical applications such as caregiver screening during hospital admissions, the five-item mastery scale is fit for purpose.

Older adults with chronic illness - Caregiver burden in the Asian context: A systematic review

INTRODUCTION

Upsurge in life expectancy, filial responsibility of caring, and healthcare advances have increased the older adult population in Asia. The last decade has witnessed nuclear families' proliferation in Asia, leaving family caregivers with more accountability and responsibility. This review explores the pattern of caregiver burden among caregivers of older adults with chronic illness in Asia.

METHODS

PRISMA guidelines serves as the framework for this systematic review. Studies from selected databases assessed caregivers' physical state, psychological dysfunction, and or burden as an outcome measure. The Newcastle - Ottawa Quality Assessment Scale appraised the quality of the selected studies.

RESULTS

The review included 12 research articles. Caregivers consistently report mild to a moderate burden. Care recipient with functional dependency, comorbidities, memory, and sleep impairments, escalate caregiver burden. Caregiver variables intensifying burden were advancing age, male gender, spouse as a care recipient, longer care provision duration, and no assistance.

CONCLUSION

Optimal levels of emotional well-being, significant family/social support, and self-preparedness among caregivers are grounds for their empowerment.

PRACTICAL IMPLICATIONS

A paradigm shift from 'caregiver burden' to 'caregiver resilience' is advocated. Routine screening, preventive measures (skill-building and psychosocial empowerment), and restorative services (respite care and problem-based home visiting) for caregivers are forecasted.

Cardiovascular Disease Incidence and Risk in Family Caregivers of Adults With Chronic Conditions: A Systematic Review

BACKGROUND

Family caregivers experience psychological distress or physical strain that may lead to an increased risk of cardiovascular disease (CVD) morbidity and mortality.

OBJECTIVE

This systematic review aimed to describe the current evidence and gaps in the literature on measures used to assess CVD outcomes in family caregivers, the association of caregiving with CVD incidence/risk outcomes, and associated factors in family caregivers of patients with chronic disease.

METHODS

Medline, PubMed, CINAHL, Web of Science, and Google Scholar were searched for English-language, peer-reviewed studies published from 2008 to 2020 that examined CVD incidence and risk among family caregivers of adults with chronic conditions.

RESULTS

Forty-one studies were included in this review. The measures used to assess CVD risk were categorized into biochemical, subclinical markers, components of metabolic syndrome, and global risk scores. Compared with noncaregivers, caregivers were more likely to have higher CVD incidence rates and objectively measured risk. Cardiovascular disease risks were also increased by their caregiving experience, including hours/duration of caregiving, caregivers' poor sleep status, psychological symptoms, poor engagement in physical/leisure activities, and care recipient's disease severity.

CONCLUSIONS

Although there were limited longitudinal studies in caregivers of patients with diverse health conditions, we found evidence that caregivers are at high risk of CVD. Further research for various caregiver groups using robust methods of measuring CVD risk is needed. Caregiver factors should be considered in developing interventions aimed at reducing CVD risk for caregivers.

Sexual orientation, disclosure, and cardiovascular stress reactivity

Stigma may strain the heart health of lesbian, gay, and bisexual (LGB) individuals. To date, however, LGB-related differences in cardiovascular diagnosis, risk factors, and basal biomarkers are inconsistently reported. Using a laboratory-based stress paradigm, the current study assessed whether cardiovascular stress reactivity differs as a function of sexual orientation and disclosure status ("coming out") in a sample of healthy young LGB and heterosexual adults. Eighty-seven participants aged 18-45 (M = 24.61 ± 0.61 SE) identifying as LGB and heterosexual (47%) were exposed to the Trier Social Stress Test, a well-validated laboratory stressor involving public speaking and mental arithmetic. Throughout a two-hour session, ambulatory recordings for heart rate and blood pressure were collected. Self-report questionnaires were also administered to assess psychosocial and demographic variables. Gay/bisexual men showed higher heart rate and lesbian/bisexual women showed marginally higher mean arterial blood pressure in response to a stressor, compared to sex- and age-matched heterosexuals. No significant differences emerged when comparing LGB individuals who had completely disclosed and those that had not completely disclosed their sexual orientation to family and friends. Compared to heterosexuals, heart rate is higher among gay/bisexual men and blood pressure is marginally higher among lesbian/bisexual women when exposed to a laboratory-based stressor. These preliminary findings contribute to small literature on sexual orientation differences in stress reactive biomarkers that requires further exploration. Lay abstract In response to stress exposure in a laboratory, gay/bisexual men showed higher heart rate than heterosexual men. By contrast, lesbian/bisexual showed a non-significant tendency towards higher blood pressure than heterosexual women. These preliminary findings suggest that the heart health of LGB individuals might be strained by stigma exposure.

Exploring the association between optimism and quality of life among informal caregivers of persons with dementia

ABSTRACTObjective:We aimed to analyze the relationship between optimism and quality of life (QoL) among informal caregivers of patients with dementia (PWD).

DESIGN

In this cross-sectional study, a hierarchical multiple linear regression analysis was used to determine the association between optimism and caregiver's QoL after controlling the effect of different covariates, including burden.

PARTICIPANTS

A sample of 130 PWD and their informal caregivers underwent a comprehensive protocol of assessment.

MEASUREMENTS

Caregivers completed the Battery of Generalized Expectancies of Control Scales, the Zarit Burden Interview, and the World Health Organization Quality of Life-Brief as measure of QoL. Optimism was estimated based on the combination of three expectancies of control, namely, self-efficacy, contingency, and success.

RESULTS

QoL correlated positively with optimism and negatively with burden. Optimism predicted each dimension of QoL, even after controlling for the effect of sociodemographic, care-recipients' clinical covariates, and burden in all models.

CONCLUSION

Optimism consistently predicted well-being and QoL in informal caregivers of PWD.

The influence of mastery on mother's health in middle years: Moderating role of stressful life context

Using data from 416 middle-aged mothers gathered over the course of a decade, this study examined the influence of mastery trajectories (the initial level and change), on change in physical health. Mastery is defined as one's ability to control and influence his/her life and environment to reach a desired outcome or goal. Both the initial level and change in mastery from 1991 to 1994 were associated with decreased physical health problems over the middle years (1991-2001). Contextual moderation of this association by stressful life contexts including negative life events and work-family conflict was investigated. Moderation analysis showed that under conditions of low contextual life stressors, the level and increase in mastery significantly contributed to decreases in physical health problems in middle-aged mothers. Alternatively, conditions of high contextual life stressors inhibited the ability of mastery to influence physical health of mothers, suggesting that the positive health impact of mastery on physical health is mitigated by stressful life experiences. Implications for the need to maintain important personal resources, such as mastery, during times of stress are discussed.

Emotional reactivity to daily life stress in spousal caregivers of people with dementia: An experience sampling study

Introduction

Caregivers differ in their emotional response when facing difficult situations during the caregiving process. Individual differences in vulnerabilities and resources could play an exacerbating or buffering role in caregivers’ reactivity to daily life stress. This study examines which caregiver characteristics modify emotional stress reactivity in dementia caregivers.

Methods

Thirty caregivers collected momentary data, as based on the experience sampling methodology, to assess (1) appraised subjective stress related to events and minor disturbances in daily life, and (2) emotional reactivity to these daily life stressors, conceptualized as changes in negative affect. Caregiver characteristics (i.e. vulnerabilities and resources) were administered retrospectively.

Results

Caregivers who more frequently used the coping strategies ‘seeking distraction’, ‘seeking social support’, and ‘fostering reassuring thoughts’ experienced less emotional reactivity towards stressful daily events. A higher educational level and a higher sense of competence and mastery lowered emotional reactivity towards minor disturbances in daily life. No effects were found for age, gender, and hours of care and contact with the person with dementia.

Discussion

Caregiver resources can impact emotional reactivity to daily life stress. Interventions aimed at empowerment of caregiver resources, such as sense of competence, mastery, and coping, could help to reduce stress reactivity in dementia caregivers.

Relationship between Mastery and Caregiving Competence in Protecting against Burden, Anxiety and Depression among Caregivers of Frail Older Adults

OBJECTIVE

Studies suggest the protective effect of mastery and caregiving competence against psychological stressors of caregiving in the context of dementia, although the interplay between the two with caregiver outcomes is not well understood. This study examines the independent and moderating impact of mastery and caregiving competence on burden, anxiety and depression among caregivers of older adults with frailty-related care needs.

DESIGN, SETTING AND PARTICIPANTS

This is a cross-sectional study of 274 older adults-family caregiver dyads from a hospital in Singapore. Mean ages of the older adults and their caregivers were 85 and 59 years respectively.

MEASUREMENTS

We performed hierarchical linear regression models to examine the independent influence of mastery and caregiving competence on caregiver burden, anxiety and depression. We also examined the interaction effect between mastery and caregiving competence for each outcome.

RESULTS

Mastery and caregiving competence were independently negatively associated with caregiver burden, anxiety and depression. Mastery explained more variance than caregiving competence and had a stronger correlation with all outcomes. There was a statistically significant interaction between mastery and caregiving competence for depression (interaction term beta=.14, p<0.01), but not burden and anxiety. High levels of mastery are associated with less depression. particularly among caregivers with below-average levels of caregiving competence. Likewise, high levels of caregiving competence are associated with less depression. particularly among caregivers with below-average levels of mastery.

CONCLUSION

Our findings suggest potential benefits adressing targeted interventions for mastery and caregiving competence of caregivers to older adults as they independently influence caregiver outcomes and moderate each other's effect on depression. Mastery-based interventions should be incorporated into current caregiver training which traditionally has focused on caregiver competence alone.

Long-term caregiving is associated with impaired cardiovagal baroreflex

OBJECTIVE

Caregiving stress is associated with increased risk of cardiovascular disease (CVD). Inability to adequately regulate blood pressure is a possible underlying mechanism explaining this risk. We examined the relationship between length of caregiving and cardiovagal baroreflex sensitivity (cBRS) to better understand the link between caregiving and CVD risk.

METHODS

A total of 146 elderly individuals (≥55years) participated in this study, of whom 96 were providing in-home care to a spouse with dementia and 50 were healthy controls married to a non-demented spouse (i.e., non-caregivers). Among the caregivers, 56 were short-term caregivers (caring<4years) and 40 were long-term caregivers (caring≥4years). A multiple linear regression model, with contrast codes comparing short and long-term caregivers with non-caregivers was used to understand relationships between chronic caregiving and cBRS.

RESULTS

After controlling for relevant demographic and health characteristics, mean±SE log transformed cBRS for non-caregivers was 0.971±0.029. Relative to non-caregivers, the long-term caregivers had significantly impaired cBRS (0.860±0.033; p=0.013). However, mean cBRS for short-term caregivers did not significant differ from non-caregivers (0.911±0.028; p=0.144).

CONCLUSION

These results suggest that long-term caregiving stress is associated with an impaired cBRS. Accumulation of stress from years of caregiving could result in worse cBRS function, which could be a mechanistic explanation for the correlation between caregiving stress and the increased risk of CVD.

The Effects of the MORE Wisdom Resources on Spousal Caregivers' Life Satisfaction: An Application of the Resilience Model

OBJECTIVES

Models of resilience suggest that psychosocial resources and their interactions facilitate resilience while experiencing life challenges of caregiving. The MORE wisdom resources (sense of Mastery, Openness to experience, Reflective attitude, and Emotion regulation) have been suggested as possible personal resources of resilience that predict positive health outcomes of caregivers. Applying a model of resilience, this study examined the direct and indirect effects of the three of the MORE wisdom resources (sense of Mastery, Openness to experience, and Emotion regulation) on caregiving spouses' life satisfaction and perceived physical health.

METHODS

Using data from the survey of Midlife in the United States, caregiving spouses (n = 114) and matched non-caregivers (n = 114) were included. We compared the direct and indirect effects of the wisdom resources on life satisfaction and physical health between the two groups.

RESULTS

The simple mediation model proposed in 2008 by Preacher and Hayes revealed that openness to experience was directly associated with better life satisfaction among caregiving spouses. Sense of mastery and emotion regulation had indirect effects on life satisfaction through spousal support. The effects the wisdom resources on caregiving spouses' perceived physical health were not found.

CONCLUSIONS

This study demonstrated that the three of the MORE wisdom resources are possible personal resilience factors influencing life satisfaction among caregiving spouses. Moreover, the study showed how spousal support mediates the relationship between the wisdom resources and life satisfaction.

CLINICAL IMPLICATIONS

Interventions aiming to increase life satisfaction among caregiving spouses should focus on increasing both personal and environmental resources and strengthening the relationship of the caregiver and care recipient.

A systematic review of the psychobiological burden of informal caregiving for patients with dementia: Focus on cognitive and biological markers of chronic stress

As the physiological impact of chronic stress is difficult to study in humans, naturalistic stressors are invaluable sources of information in this area. This review systematically evaluates the research literature examining biomarkers of chronic stress, including neurocognition, in informal dementia caregivers. We identified 151 papers for inclusion in the final review, including papers examining differences between caregivers and controls as well as interventions aimed at counteracting the biological burden of chronic caregiving stress. Results indicate that cortisol was increased in caregivers in a majority of studies examining this biomarker. There was mixed evidence for differences in epinephrine, norepinephrine and other cardiovascular markers. There was a high level of heterogeneity in immune system measures. Caregivers performed more poorly on attention and executive functioning tests. There was mixed evidence for memory performance. Interventions to reduce stress improved cognition but had mixed effects on cortisol. Risk of bias was generally low to moderate. Given the rising need for family caregivers worldwide, the implications of these findings can no longer be neglected.

A Control-Based Multidimensional Approach to the Role of Optimism in the Use of Dementia Day Care Services

We examined whether grounded optimism and external locus of control are associated with admission to dementia day care centers (DCCs). A total of 130 informal caregivers were recruited from the Alzheimer's Association in Salamanca (northwest Spain). All caregivers completed an assessment protocol that included the Battery of Generalized Expectancies of Control Scales (BEEGC-20, acronym in Spanish) as well as depression and burden measures. The decision of the care setting at baseline assessment (own home vs DCC) was considered the main outcome measure in the logistic regression analyses. Grounded optimism was a preventive factor for admission (odds ratio [OR]: 0.34 and confidence interval [CI]: 0.15-0.75), whereas external locus of control (OR: 2.75, CI: 1.25-6.03) increased the probabilities of using DCCs. Depression mediated the relationship between optimism and DCCs, but this effect was not consistent for burden. Grounded optimism promotes the extension of care at home for patients with dementia.

Is salivary pH a marker of depression among older spousal caregivers for cancer patients?

The pH in saliva, which decreases due to the activation of the sympathetic nervous system, may serve as a biomarker of psychological distress in caregivers but has rarely been studied in this context. The aims are to examine the levels of salivary pH as a possible biomarker of depression among caregivers and whether depression mediates the association between caregiving status (cancer caregivers vs. non-cancer caregivers) and pH levels. Cross-sectional data were collected from 68 consecutive-sampled spouses of cancer patients, and 42 age-matched individuals. Lower levels of pH saliva were found among caregivers of cancer patients than in the comparison group. Being a caregiver, poor subjective health, higher depression, and lower mastery predicted lower pH levels. In addition, depression mediated the associations of mastery with pH levels. The study provides preliminary evidence that salivary pH may serve as an easily tested indicator of the stress of caregiving and its related depression.

Social support and mastery influence the association between stress and poor physical health in parents caring for children with developmental disabilities

To date, much of the research linking the stress of caring for children with developmental disabilities (e.g. Autism & Down syndrome) with parental health outcomes have tended to concentrate on mental health with less attention paid to the physical health consequences. Thus, this study sought to explore the psychosocial predictors of poor physical health in these caring parents. One hundred and sixty-seven parents (109 caregivers and 58 control parents) completed measures of stress, child problem behaviours, social support, mastery and physical health. Parents of children with developmental disabilities had poorer physical health compared to control parents. Stress and mastery, but not social support and problem behaviours, were significant predictors of poor physical health within caring parents for children with developmental disabilities. However, the association between mastery and physical health was mediated by perceived stress such that those parents who were higher on mastery reported less stress and better physical health; furthermore, the association between stress and physical health was moderated by social support; those parents high on social support and low in stress had better physical health. These results indicate that the paths between psychosocial factors and poor physical health in the caring parents are working synergistically rather than in isolation. They also underscore the importance of providing multi-component interventions that offer a variety of psychosocial resources to meet the precise needs of the parents.

Why does placement of persons with Alzheimer's disease into long-term care improve caregivers' well-being? Examination of psychological mediators

Caregiving for individuals with Alzheimer's disease is associated with chronic stress and elevated symptoms of depression. Placement of the care receiver (CR) into a long-term care setting may be associated with improved caregiver well-being; however, the psychological mechanisms underlying this relationship are unclear. This study evaluated whether decreases in activity restriction and increases in personal mastery mediated placement-related reductions in caregiver depressive symptoms. In a 5-year longitudinal study of 126 spousal Alzheimer's disease caregivers, we used multilevel models to evaluate placement-related changes in depressive symptoms (short form of the Center for Epidemiologic Studies Depression scale), activity restriction (Activity Restriction Scale), and personal mastery (Pearlin Mastery Scale) in 44 caregivers who placed their spouses into long-term care relative to caregivers who never placed their CRs. The Monte Carlo method for assessing mediation was used to evaluate the significance of the indirect effect of activity restriction and personal mastery on postplacement changes in depressive symptoms. Placement of the CR was associated with significant reductions in depressive symptoms and activity restriction and was also associated with increased personal mastery. Lower activity restriction and higher personal mastery were associated with reduced depressive symptoms. Furthermore, both variables significantly mediated the effect of placement on depressive symptoms. Placement-related reductions in activity restriction and increases in personal mastery are important psychological factors that help explain postplacement reductions in depressive symptoms. The implications for clinical care provided to caregivers are discussed.

Physiological and functional consequences of caregiving for relatives with dementia

BACKGROUND

Chronic stress negatively affects health and well-being. A growing population of informal dementia caregivers experience chronic stress associated with extraordinary demands of caring for a relative with dementia. This review summarizes physiological and functional changes due to chronic dementia caregiver stress.

METHODS

A literature search for papers assessing effects of dementia caregiving was conducted focusing on publications evaluating differences between caregivers and non-caregivers in objective measures of health and cognition.

RESULTS

The review identified 37 studies describing data from 4,145 participants including 749 dementia caregivers and 3,396 non-caregiver peers. Objective outcome measures affected in dementia caregivers included markers of dyscoagulation, inflammation, and cell aging as well as measures of immune function, sleep, and cognition. Though diverse in designs, samples, and study quality, the majority of the studies indicated increased vulnerability of dementia caregivers to detrimental changes in health and cognition. Demographic and personality characteristics moderating or mediating effects of chronic stress in caregivers were also reviewed.

CONCLUSIONS

There is accumulating evidence that chronic dementia caregiver stress increases their vulnerability to disease and diminishes their ability to provide optimal care. Clinicians and society need to appreciate the extent of deleterious effects of chronic stress on dementia caregiver health.

Inflammation and Coagulation as Mediators in the Relationships Between Religious Attendance and Functional Limitations in Older Adults

OBJECTIVE

The aim of this study was to examine inflammation and coagulation, which are positively linked to disability and inversely linked to increased religious attendance, as mediators in the cross-sectional relationships between religious attendance and functional status.

METHOD

Frequency of attendance and limitations in basic activities of daily living (ADLs), instrumental activities (IADLs), and mobility were assessed in 1,423 elders.

RESULTS

More frequent attendance was associated with fewer ADL, IADL, and mobility limitations, and with lower levels of inflammation and coagulation including interleukin-6, soluble vascular cell adhesion molecule, and D-dimer. Inflammation and coagulation partially mediated the associations between attendance and function. Eight percent of the effect of attendance on ADL (p = .014), 5% of the effect on IADL (p = .003), and 8% of the effect on mobility (p = .001) limitations were due to inflammation and coagulation.

DISCUSSION

Relationships between attendance and function may be due in part to lower levels of inflammation and coagulation among elders who attend services.

A prospective study of volunteerism and hypertension risk in older adults

The purpose of the current study was to determine whether volunteerism is prospectively associated with hypertension risk among older adults. Participants provided data during the 2006 and 2010 waves of the Health and Retirement Study, a longitudinal panel survey using a nationally representative sample of community-dwelling older adults (age > 50 years). Volunteerism and blood pressure were measured at baseline and again 4 years later. Analyses excluded individuals hypertensive at baseline and controlled for age, race, sex, education, baseline systolic/diastolic blood pressure, and major chronic illnesses. Those who had volunteered at least 200 hr in the 12 months prior to baseline were less likely to develop hypertension (OR = 0.60; 95% CI [0.40, 0.90]) than nonvolunteers. There was no association between volunteerism and hypertension risk at lower levels of volunteer participation. Volunteering at least 200 hr was also associated with greater increases in psychological well-being (B = 0.99, β = .05, p = .006) and physical activity (B = 0.21, β = .05, p = .04) compared with nonvolunteers; however, these factors did not explain the association of volunteerism with hypertension risk.

Substantial changes in mastery perceptions of dementia caregivers with the placement of a care recipient

OBJECTIVES

The current study examined how a key component of caregiving stress processes, global mastery perceptions, changes with placing the care recipient in a nursing home or institution. We also explored the role of primary stressors in accounting for mastery changes with placement and whether characteristics of the caregiver and care recipient moderate reactions to placement.

METHOD

We applied multiphase growth curve models to prospective longitudinal data from 271 caregivers in the Caregiver Stress and Coping Study who experienced placement of their care recipient.

RESULTS

Using a time-to/from-placement metric, we found that caregivers typically experienced declines in mastery preceding placement, followed by a significant increase within 1 year after placement and further increases thereafter. Corresponding changes in primary stressors (role overload) mediated the placement-related increase in mastery. Caregivers who reported more depressive symptoms and activities of daily living/instrumental activities of daily living dependencies of the care recipient were more likely to experience larger placement-related increases in mastery perceptions.

DISCUSSION

Our findings suggest that placement alters psychological resources of caregivers and this effect is driven by corresponding changes in primary stressors. Findings also underscore the importance of examining change processes across salient life events and transitions.

Ways of coping and biomarkers of an increased atherothrombotic cardiovascular disease risk in elderly individuals

Objective. To investigate the relationship between coping and atherothrombotic biomarkers of an increased cardiovascular disease (CVD) risk in the elderly. Methods. We studied 136 elderly caregiving and noncaregiving men and women who completed the Ways of Coping Checklist to assess problem-focused coping, seeking social support (SSS), blamed self, wishful thinking, and avoidance coping. They had circulating levels of 12 biomarkers measured. We also probed for potential mediator and moderator variables (chronic stress, affect, health behavior, autonomic activity) for the relation between coping and biomarkers. Results. After controlling for demographic and CVD risk factors, greater use of SSS was associated with elevated levels of serum amyloid A (P = 0.001), C-reactive protein (CRP) (P = 0.002), vascular cellular adhesion molecule (VCAM)-1 (P = 0.021), and D-dimer (P = 0.032). There were several moderator effects. For instance, greater use of SSS was associated with elevated VCAM-1 (P < 0.001) and CRP (P = 0.001) levels in subjects with low levels of perceived social support and positive affect, respectively. The other coping styles were not significantly associated with any biomarker. Conclusions. Greater use of SSS might compromise cardiovascular health through atherothrombotic mechanisms, including elevated inflammation (i.e., serum amyloid A, CRP, VCAM-1) and coagulation (i.e., D-dimer) activity. Moderating variables need to be considered in this relationship.

Toward a more complete understanding of the effects of personal mastery on cardiometabolic health

OBJECTIVE

A great deal of research has been devoted to identifying the psychological factors that might be associated with reduced risk for cardiovascular diseases. In particular, coping resources such as personal mastery might attenuate stress-related pathophysiology. The purpose of the present review was to examine the existing literature reporting associations between personal mastery and cardiometabolic health outcomes to determine which outcomes have been studied to date, investigate the extent of inconsistency in the literature, and propose new directions for research.

DESIGN

Systematic review of articles examining the associations between personal mastery and cardiometabolic health.

MAIN OUTCOME MEASURES

Studies were included if they examined objective measures of cardiometabolic function, cardiovascular events, and/or mortality.

RESULTS

Thirty-two studies were identified examining the effect of mastery on the following outcomes: mortality and/or cardiovascular events, psychoneuroendocrine stress systems, cardiovascular reactivity to acute stress, metabolic dysregulation, inflammation/coagulation, and evidence of large vessel disease from imaging methods.

CONCLUSIONS

Overall, mastery was associated with better cardiometabolic health and reduced risk for disease and/or death, typically with a small-medium effect size. A relatively small proportion of studies reported contradictory findings that higher mastery was associated with poorer cardiometabolic outcomes. The state of the current research suggests that future investigations should focus on 1) clarifying the mediators and moderators most relevant in the association between mastery and downstream disease, 2) testing the association between mastery and biological outcomes longitudinally, 3) examining the physiological impact of mastery-increasing interventions, and 4) studying the relationship between mastery and disease risk in diverse ethnic or sociocultural groups.

A review of the psychobiology of dementia caregiving: a focus on resilience factors

The recent aging trend in the United States has resulted in exponential growth in the number of informal dementia caregivers. Caring for a family member with dementia has been associated with negative health outcomes that are likely related to physiologic changes resulting from stress. However, caregiving is not always associated with health morbidity. In this review, we highlight resilience factors that appear to have a beneficial relationship with health outcomes. Specifically, we highlight 11 studies that examined the relationship of one of three broad resilience domains (personal mastery, self-efficacy, and coping style) to caregiver health outcomes. Our main findings were that higher levels of personal mastery and self-efficacy, and increased use of positive coping strategies appear to have a protective effect on various health outcomes in dementia caregivers. Continued research is warranted to help guide prospective directions for caregiver interventions focusing on increasing caregiver resilience and the corresponding impact on caregiver health.

How much striving is too much? John Henryism active coping predicts worse daily cortisol responses for African American but not white female dementia family caregivers

INTRODUCTION

The John Henryism active coping (JHAC) hypothesis suggests that striving with life challenges predicts increased risk for cardiovascular disease for those with scarce coping resources. This study examined the moderating role of JHAC in the associations of 1) caregiver status and 2) care recipient functional status with diurnal salivary cortisol patterns among 30 African Americans (AAs) and 24 white female dementia caregivers and 63 noncaregivers (48 AAs).

METHODS

Caregiver participants completed the JHAC-12 scale, Activities of Daily Living (ADL) scale, and Revised Memory and Behavior Problem checklist (RMBPC) and collected five saliva samples daily (at awakening, 9 A.M., 12 P.M., 5 P.M., and 9 P.M.) for 2 successive days.

RESULTS

Univariate analysis of variance tests with mean diurnal cortisol slope as the outcome illustrated that among AA caregivers, higher JHAC scores were related to flatter (or more dysregulated) cortisol slopes. The JHAC by ADL and JHAC by RMBPC interactions were each significant for AA caregivers. Among AA caregivers who reported higher ADL and RMBPC scores, higher JHAC scores were associated with flatter cortisol slopes.

CONCLUSIONS

These findings extend recent studies by showing that being AA, a caregiver, and high in JHAC may elevate the risk for chronic disease, especially for those with higher patient ADL and behavioral problems. Thus, it is imperative that interventions appreciate the pernicious role of high-effort coping style, especially for AA caregivers, to minimize the stressful side effects of patient ADL and memory and behavioral problems for the caregiver.

Psychological protective factors across the lifespan: implications for psychiatry

Although there are many challenges in operationally defining and measuring positive psychological constructs, there is accumulating evidence that optimism, resilience, positive attitudes toward aging, and spirituality are related to reduced risk for morbidity and mortality in older age. This article reviews the definition, measurement, associations, and putative mechanisms of selected positive psychological constructs on subjective and objective indicators of health with a focus on the latter half of the lifespan.

Carotid plaque in Alzheimer caregivers and the role of sympathoadrenal arousal

OBJECTIVES

To test the hypothesis that those who provide care for a spouse diagnosed with Alzheimer's disease would have increased prevalence of carotid artery plaque compared with noncaregiving controls and that prolonged sympathoadrenal arousal to acute stress would relate to this difference. Providing care for a spouse with Alzheimer's disease has been associated with an increased risk of coronary heart disease, potentially due to the impact of caregiving stress on the atherosclerotic disease process.

METHODS

Participants were 111 spousal caregivers (74 ± 8 years of age; 69% women) to patients with Alzheimer's disease and 51 noncaregiving controls (75 ± 6 years of age; 69% women). Inhome assessment of carotid artery plaque via B-mode ultrasonography was conducted. Plasma catecholamine response to an acute speech stressor task was also measured.

RESULTS

Logistic regression indicated that caregiving status (i.e., caregiver versus noncaregiver) was associated significantly with a 2.2 times greater odds for the presence of plaque independent of other risk factors of atherosclerosis (95% confidence interval, 1.01-4.73, p = .048). Decreased recovery to basal levels of epinephrine after a psychological stress task was associated significantly with the presence of plaque in caregivers, but not in noncaregivers. Norepinephrine recovery post stressor was not associated with plaque in either group.

CONCLUSIONS

Caregivers had a higher frequency of carotid plaque compared with noncaregivers. Poorer epinephrine recovery after acute stress was associated with the presence of plaque in caregivers but not in noncaregivers. A prolonged sympathoadrenal response to acute stress might enhance the development of atherosclerosis in chronically stressed Alzheimer caregivers.

Self-efficacy buffers the relationship between dementia caregiving stress and circulating concentrations of the proinflammatory cytokine interleukin-6

OBJECTIVE

the proinflammatory cytokine interleukin (IL)-6 has been linked with health morbidity, particularly risk for cardiovascular disease (CVD). The purpose of this study was to investigate the potential protective role of coping self-efficacy on the relationship between caregiving stress and circulating concentrations of IL-6.

METHODS

a total of 62 elderly caregivers of patients with Alzheimer's disease (mean age: 74 years) were assessed for plasma concentrations of IL-6, caregiving-related overload, and coping self-efficacy. Multiple regression was used to examine the main effects of stress and self-efficacy, as well as the interaction between stress and self-efficacy, in predicting plasma IL-6 after controlling for age, gender, resting blood pressure, and obesity.

RESULTS

there was a significant interaction between stress and self-efficacy in predicting IL-6. Post-hoc examination indicated that when self-efficacy was low, stress was significantly related to IL-6 (β = 0.43). However, when self-efficacy was high, stress was not significantly related to IL-6 (β = -0.10).

CONCLUSION

caregiving stress in combination with low coping self-efficacy is significantly related to IL-6, a known risk marker for health morbidity, particularly CVD. However, stress was not associated with IL-6 with high self-efficacy. Although limited and preliminary, these results point to a potential protective effect of self-efficacy on caregiver health that can be tested in longitudinal studies.

Video-based coping skills to reduce health risk and improve psychological and physical well-being in Alzheimer's disease family caregivers

OBJECTIVE

To determine whether video-based coping skills (VCS) training with telephone coaching reduces psychosocial and biological markers of distress in primary caregivers of a relative with Alzheimer's disease or related dementia (ADRD).

METHODS

A controlled clinical trial was conducted with 116 ADRD caregivers who were assigned, alternately as they qualified for the study, to a Wait List control condition or the VCS training arm in which they viewed two modules/week of a version of the Williams LifeSkills Video adapted for ADRD family care contexts, did the exercises and homework for each module presented in an accompanying Workbook, and received one telephone coaching call per week for 5 weeks on each week's two modules. Questionnaire-assessed depressive symptoms, state and trait anger and anxiety, perceived stress, hostility, caregiver self-efficacy, salivary cortisol across the day and before and after a stress protocol, and blood pressure and heart rate during a stress protocol were assessed before VCS training, 7 weeks after training was completed, and at 3 months' and 6 months' follow-up.

RESULTS

Compared with controls, participants who received VCS training plus telephone coaching showed significantly greater improvements in depressive symptoms, trait anxiety, perceived stress, and average systolic and diastolic blood pressures that were maintained over the 6-month follow-up period.

CONCLUSIONS

VCS training augmented by telephone coaching reduced psychosocial and biological indicators of distress in ADRD caregivers. Future studies should determine the long-term benefits to mental and physical health from this intervention.

Effects of Alzheimer caregiving on allostatic load

This study aimed to determine if Alzheimer caregivers have increased allostatic load compared to non-caregivers. Potential psychological moderators (mastery, depression, and role overload) of the relationship between caregiving status and allostatic load were also explored. Eighty-seven caregivers and 43 non-caregivers underwent biological assessment of allostatic load and psychological assessments. Caregivers had significantly higher allostatic load compared to non-caregivers ( p < .05). Mastery, but not depression or overload, moderated the relationship between caregiving status and allostatic load. In conclusion, allostatic load may represent a link explaining how stress translates to downstream pathology, but more work is necessary to understand the role of psychological factors.

Association between chronic caregiving stress and impaired endothelial function in the elderly

OBJECTIVES

We examined the relationship between chronic caregiving stress and endothelial function.

BACKGROUND

Evidence suggests that caregiving stress is associated with pathophysiologic processes related to atherosclerosis. Endothelial dysfunction is a possible underlying mechanism explaining the relationship between caregiving stress and cardiovascular morbidity. We investigated the relationship between chronic caregiving stress and endothelial dysfunction assessed by reactive hyperemia-induced flow-mediated dilation (FMD).

METHODS

Seventy-eight elderly individuals participated in the study. Fifty-five were providing in-home care to a spouse with Alzheimer's disease, and 23 were married and living with a healthy, nondemented spouse. Analysis of covariance was used to examine the relationships between advancing dementia severity (Clinical Dementia Rating scores) and FMD and nitroglycerin-induced vasodilation of the brachial artery. Multiple linear regression was used to examine the relationship between years of caregiving and FMD.

RESULTS

Clinical Dementia Rating scale scores were significantly related to FMD (p = 0.033), with participants caring for a spouse with moderate to severe dementia showing significantly worse FMD than those caring for a spouse with mild dementia (p = 0.028) and noncaregivers (p = 0.032). Within the caregiver sample, the number of years of caregiving was significantly related to FMD (r = -0.465, p < 0.001).

CONCLUSIONS

These results suggest that the chronic stress of caregiving is associated with impaired endothelial function, which may be a potential mechanistic link to the observed increased risk of cardiovascular disease in elderly caregivers.

Insomnia In Caregivers Of Persons With Dementia: Who Is At Risk And What Can Be Done About It?

Sleep problems are associated with mood and function disturbances in caregivers of persons with Alzheimer's disease (AD). However, the factors associated with the onset and maintenance of sleep disturbances in caregivers of persons with dementia are unknown, and little attention has been paid to treatments to improve sleep in caregivers. Here we review some of the evidence for the association between caregiver sleep problems, and caregiver and care-recipient demographic, health, and psychosocial variables. We present data from a longitudinal study that examined factors associated with self-reported sleep problems in dementia caregivers and care-recipients over a 5-year follow-up period, and describe the existing caregiver insomnia treatment literature. We conclude with recommendations for future research.

Personal mastery and lower body mobility in community-dwelling older persons: the Invecchiare in Chianti study

OBJECTIVES

To test the hypothesis that, in older persons, sense of personal mastery, defined as the extent to which one regards one's life chance as being under one's own control, predicts change in lower extremity performance during a 6-year follow-up.

DESIGN

Prospective cohort study.

SETTING

Community based.

PARTICIPANTS

Six hundred twenty-six participants aged 65 and older.

MEASUREMENTS

Personal mastery was assessed at baseline using Pearlin's mastery scale. Lower extremity performance was measured at baseline and at 6-year follow-up using the Short Physical Performance Battery (SPPB) of lower extremity function.

RESULTS

Higher sense of mastery was associated with a significantly less-steep decline in lower extremity performance. Participants in the two lowest quartiles of personal mastery had, respectively, a 2.6 (95% confidence interval (CI)=1.4-5.1, P=.01) and 3.2 (95% CI=1.6-6.6, P=.002) higher risk of experiencing a substantial decline (> or =3 points) in SPPB scores after 6 years as those in the highest quartile.

CONCLUSIONS

Older individuals with poor sense of personal mastery are at high risk of accelerated lower extremity physical function decline. Whether interventions aimed at improving personal mastery may prevent disability remains unknown.
