Impact of informal caregiving on depressive symptoms among a national cohort of men.

BACKGROUND: There is evidence that unpaid caregiving can have negative effects on the mental health of female caregivers; however, evidence of impacts on male caregivers is limited. This study addressed this gap by examining associations between becoming a caregiver and depressive symptoms among men. METHODS: We used data from waves 1-2 (2013, 2016) of the Longitudinal Study of Australian Male Health (Ten to Men). Effects of incident caregiving on depressive symptoms were estimated using augmented inverse probability treatment weighting, with adjustment for potential confounders. Incident caregiving was assessed as a binary variable (became a caregiver vs not), and depressive symptoms were measured using the Patient Health Questionnaire (moderate to severe depressive symptoms; yes, no). Main analysis was prospective, drawing on wave 1 (caregiving) and wave 2 (depressive symptoms), and sensitivity analyses modelled cross-sectional associations. RESULTS: In the main analysis, incident caregiving in wave 1 was associated with depressive symptoms in the subsequent wave, with an average treatment effect of 0.11 (95% CI 0.06, 0.17) and equating to a risk ratio of 2.03 (95% CI 1.55, 2.51). Associations were robust to several sensitivity analyses, with cross-sectional associations supporting the main prospective analyses. CONCLUSION: These results provide evidence of the association between caregiving and depressive symptoms among male caregivers. This has important implications for policy and support programmes. As we seek to shift caregiving responsibilities toward a more gender-equal distribution of care, policy must recognise that, like female caregivers, male caregivers also experience mental health impacts related to their caregiving role.

A Double Whammy? Psychosocial Disadvantages of Dementia Caregivers with Cancer Histories.

Guided by the Diathesis-Stress model, this study examined how cancer history interacted with caregiving status to determine the psychosocial functioning of dementia caregivers. This study assessed a set of indicators for psychological health and social connections among 85 spousal caregivers of persons with Alzheimer's disease and 86 age- and gender-matched spouses of healthy controls at study entry and 15-18 months later. Results showed that dementia caregivers with cancer histories reported lower social connections relative to caregivers without cancer histories or non-caregivers with or without cancer histories, and reported lower psychological health relative to non-caregivers with and without cancer histories at two time points. The findings highlight that a history of cancer is a predisposing vulnerability factor for psychosocial dysfunctions among dementia caregivers and address gaps in knowledge about the psychosocial adjustment of cancer survivors as caregivers.

Caregiver Psychological Distress: Longitudinal Relationships With Physical Activity and Diet.

Given limited longitudinal research with caregivers (CGs, n = 122) of spouses with Alzheimer disease, and demographically matched noncaregivers (NCGs, n = 117), we compared these groups on psychological distress (anxiety, depression), burden, and health behaviors over 2 years. Analyses examined group differences in relationships of micronutrient recommended daily allowances (RDAs) and physical activity considering hours of care, psychological distress, and burden. Participants were measured and assessed on whether they met micronutrient intake and physical activity totaled over an average week. Regression analyses showed a total effect whereby NCGs had greater increases in meeting micronutrient allowances (RDAs) than CGs (b = 10.91, standard error [SE] = 4.74, 95% confidence interval [CI]: 1.56-20.26). Additionally, over time, NCGs had greater increases in physical activity, which was mediated by hours of care (b = 0.149, SE = 0.060, 95% CI: 0.034-0.270). These results suggest CGs may lack proper nutrients, and care hours may influence their health behaviors.

Social Determinants of Health: Underreported Heterogeneity in Systematic Reviews of Caregiver Interventions.

BACKGROUND AND OBJECTIVES: Although most people have some experience as caregivers, the nature and context of care are highly variable. Caregiving, socioeconomic factors, and health are all interrelated. For these reasons, caregiver interventions must consider these factors. This review examines the degree to which caregiver intervention research has reported and considered social determinants of health. RESEARCH DESIGN AND METHODS: We examined published systematic reviews and meta-analyses of interventions for older adults with age-related chronic conditions using the PRISMA and AMSTAR 2 checklists. From 2,707 papers meeting search criteria, we identified 197 potentially relevant systematic reviews, and selected 33 for the final analysis. RESULTS: We found scant information on the inclusion of social determinants; the papers lacked specificity regarding race/ethnicity, gender, sexual identity, socioeconomic status, and geographic location. The majority of studies focused on dementia, with other conditions common in later life vastly underrepresented. DISCUSSION AND IMPLICATIONS: Significant gaps in evidence persist, particularly for interventions targeting diverse conditions and populations. To advance health equity and improve the effectiveness of interventions, research should address caregiver heterogeneity and improve assessment, support, and instruction for diverse populations. Research must identify aspects of heterogeneity that matter in intervention design, while recognizing opportunities for common elements and strategies.

Demographic-Specific Rates for Life Events in the Cardiovascular Health Study and Comparisons With Other Studies.

PURPOSE OF THE STUDY: (1a) We use the Cardiovascular Health Study (CHS), a multi-site heterogeneous sample of Medicare enrollees (N = 5,849) to provide rates for specific life events experienced within 6 months; (1b) We present rates for 29 other studies of community-residing older adults (N = 41,308); (2) For the CHS, we provide demographic-specific rates and predicted probabilities for age [young-old (65-75) vs old-old (≥75)], gender, race, marital status, and education. DESIGN/METHODS: The CHS sample is 57.6% women, 84.2% white (15.8% black), and 66.3% married. Mean age is 72.8 years (standard deviation [SD] = 5.6, range = 65-100) and education is 13.7 years (SD = 4.8). Life events were interviewer-assessed. Regressions estimated associations of life event rates with demographic groups (e.g., age), controlling for other demographic variables (e.g., gender, etc.). RESULTS: (1a) CHS rates ranged from 44.7% (death of someone close) to 1.1% (retirement/work changes). (1b) Most life event studies used total scores and only 5 that met our inclusion criteria used time intervals <1 year; longer intervals were associated with higher rates. (2) In the CHS, the life event for illnesses was related to 5 demographic variables (net the other 4 demographic variables), difficulties caregiving to 4, and worse relationships to 3 demographic variables. Race was related to 8 life events, marital status to 7, education to 6, and age to 4 events. IMPLICATIONS: By identifying demographic groups at highest risk for life events, this research focuses on older adults at greatest risk for health problems. These data are necessary for translating research into interventions, practice, and policy.

Objective and Subjective Cognitive Problems among Caregivers and Matched Non-caregivers.

Purpose of the study: Caregivers (CGs) have been shown to do more poorly than non-caregivers (NCGs) on objective cognitive tests (Trails B and Digit Symbol Test, DST), but less is known about whether these groups differ in: (a) reports of subjective cognitive problems (SCPs, memory complaints, etc.) and (b) relationships of SCPs with objective cognitive tests, depression, and stress exposure. Such relationships are important because researchers/clinicians use SCPs as proxies for objective cognitive tests. Design and methods: One hundred and twenty-two spouse CGs of persons with Alzheimer's disease and 117 demographically matched NCG spouses were compared on Trails B and DST at baseline (T1), 1 year later (T2), and 2 years later (T3) and on SCPs at T1. Results: Trails B was slower in CGs than NCGs and DST declined in CGs relative to NCGs. CGs reported more SCPs than NCGs. Depression mediated group differences in Trails and DST and was also associated with SCPs. Trails B and DST explained variance in SCPs in NCGs, but not in CGs. Hours of care explained variance in SCPs in CGs, but not in NCGs. Implications: When using SCPs to make inferences about CG cognitive function, researchers/clinicians should consider the possible influence of stress exposures and depression. The lack of associations of objective and subjective cognitive measures may be a reflection of poorer self-monitoring among CGs, a potential new area of CG research.

Does caregiving cause psychological distress? The case for familial and genetic vulnerabilities in female twins.

BACKGROUND: Informal caregiving can be deleterious to mental health, but research results are inconsistent and may reflect an interaction between caregiving and vulnerability to stress. METHODS: We examined psychological distress among 1,228 female caregiving and non-caregiving twins. By examining monozygotic and dizygotic twin pairs discordant for caregiving, we assessed the extent to which distress is directly related to caregiving or confounded by common genes and environmental exposures. RESULTS: Caregiving was associated with distress as measured by mental health functioning, anxiety, perceived stress, and depression. The overall association between caregiving and distress was confounded by common genes and environment for mental health functioning, anxiety, and depression. Common environment also confounded the association of caregiving and perceived stress. CONCLUSIONS: Vulnerability to distress is a factor in predicting caregivers' psychosocial functioning. Additional research is needed to explicate the mechanisms by which common genes and environment increase the risk of distress among informal caregivers.

Does caring for a spouse with dementia promote cognitive decline? A hypothesis and proposed mechanisms.

OBJECTIVE: To discuss why spouse caregivers (CGs) of people with dementia may be at higher risk for cognitive problems and decline than demographically similar people not caring for a spouse with dementia (noncaregivers; NCGs). DESIGN: Literature review. SETTING: Community. PARTICIPANTS: Older adults caring for a family member (primarily spouses) with dementia. MEASUREMENTS: Cognitive, psychosocial, physiological, and behavioral. RESULTS: This article reports a review of the literature examining relationships between CG status and cognitive problems in the context of a theoretical model of chronic stress. The model suggests that spouse CGs may be at higher risk of cognitive impairment or dementia than NCG spouses in response to several mediators, including psychosocial (e.g., depression, loneliness, social isolation, sleep problems), behavioral (e.g., exercise, diet), and physiological (e.g., metabolic syndrome and inflammation) variables. CONCLUSION: This research has important implications because it considers modifiable risk factors for dementia that, if unchecked, may compromise the lives of CGs and their ability to function. It is hoped that an understanding of such stress-mediator-cognitive processes will help clinicians, researchers, policy-makers, and stakeholders mitigate what may be characterized as an "ironic tragedy"-dementia in both members of the caregiving dyad-if left unchecked.

A Person-Focused Analysis of Resilience Resources and Coping in Diabetes Patients.

This study investigated the resilience resources and coping profiles of diabetes patients. A total of 145 patients with diabetes completed a questionnaire packet including two measurements of coping (COPE and Coping Styles questionnaires), and personal resources. Glycosylated hemoglobin (HbA(1c)) was also assessed. Resilience was defined by a factor score derived from measures of self-esteem, self-efficacy, self-mastery, and optimism. All of the maladaptive coping subscales were negatively associated with resilience (r's range from -.34 to -.56, all p's <.001). Of the adaptive coping subscales, only acceptance, emotional support, and pragmatism were positively associated with resilience. The upper, middle, and lower tertiles of the resilience factor were identified and the coping profiles of these groups differed significantly, with low resilience patients favoring maladaptive strategies much more than those with high or moderate resilience resources. Resilience groups did not differ in HbA(1c) levels; correlation coefficients of the coping subscales with HbA(1c) were explored. This study demonstrates a link between maladaptive coping and low resilience, suggesting that resilience impacts one's ability to manage the difficult treatment and lifestyle requirements of diabetes.

The dialectical behavior therapy ways of coping checklist: development and psychometric properties.

Skills training is a crucial mode of treatment in dialectical behavioral therapy (DBT; Linehan, 1993b), yet a psychometrically sound measure of DBT skills use does not exist. We adapted the Revised Ways of Coping Checklist (RWCCL; Vitaliano, Russo, Carr, Maiuro, & Becker, 1985) to create the DBT Ways of Coping Checklist (DBT-WCCL). Using factor analysis procedures, two subscales emerged: one assessing coping via DBT skills, the DBT Skills Subscale (DSS), and one assessing coping via dysfunctional means, the Dysfunctional Coping Subscale (DCS). Principal component, internal consistency, test-retest reliability, and content validity analyses suggested that the scale has good to excellent psychometric properties. In addition, the DSS successfully discriminated patients who received skills training during 4 months of treatment from patients who did not. Moderators of skills use are also discussed. The DBT-WCCL appears to be a promising new measure of DBT skills use.

Depressed mood mediates decline in cognitive processing speed in caregivers.

PURPOSE: Very few studies have examined cognitive decline in caregivers versus noncaregivers, and only 1 study has examined mediators of such decline. We evaluated the relationship between caregiver status and decline on the digit symbol test (DST; a measure of processing speed, attention, cognitive-motor translation, and visual scanning) and whether this relationship was mediated by depressed mood. DESIGN AND METHODS: Caregivers for spouses with Alzheimer's disease (n = 122) were compared with demographically similar noncaregiver spouses (n = 117) at study entry (Time 1 = T1), T2 (1 year later), and T3 (2 years after T1). RESULTS: Caregivers had lower DST scores and higher Hamilton depression scores at T1, T2, and T3 than noncaregivers (all p < .05). Hierarchical linear modeling revealed that although caregivers started well below noncaregivers, they experienced a more rapid rate of decline than noncaregivers (p = .047). Caregivers declined 4.5 times faster than noncaregivers. Greater depressed mood at T1 (p < .01) and T2 (p < .01) predicted DST decline and mediated DST decline in caregivers vs. noncaregivers. IMPLICATIONS: Depressed mood in caregivers relative to noncaregivers may influence their greater risk for DST decline. This is important because the DST predicts problem solving and everyday functions necessary for independent living and the potential well-being of their care recipients.

How does anger coping style affect glycemic control in diabetes patients?

BACKGROUND: Although various forms of anger have been found to influence the psychological and physical health in many chronic illness populations, little is known about the effects of anger in diabetes patients. PURPOSE: Associations between anger coping style, diabetes-related psychological distress, and glycosylated hemoglobin (HbA1c) were examined in 100 diabetes patients. METHOD: Participants completed the Problem Areas in Diabetes and Coping Styles questionnaires, and had HbA1c assessments at study entry (Time 1 = T1), six months (T2), and 12 months after T1 (T3). RESULTS: Linear regression analyses revealed T1 anger coping associated with T3 HbA1c (beta = .22, p < .05), but T1 HbA1c did not associate with T3 anger coping (beta = .13, p = NS). After controlling for significant covariates (of gender, age, education, type and duration of diabetes), regression analyses revealed that T2 diabetes-related psychological distress partially mediated this association. CONCLUSION: These results suggested that higher levels of anger coping may promote poorer glycemic control in diabetes patients by provoking greater diabetes-related distress. Areas of future research on this topic are discussed.

The role of resilience on psychological adjustment and physical health in patients with diabetes.

OBJECTIVE: This study used a longitudinal design to investigate the buffering role of resilience on worsening HbA(1c) and self-care behaviours in the face of rising diabetes-related distress. METHOD: A total of 111 patients with diabetes completed surveys and had their glycosylated haemoglobin (HbA(1c)) assessed at baseline and at 1-year follow-up. Resilience was defined by a factor score of self-esteem, self-efficacy, self-mastery and optimism. Diabetes-related distress and self-care behaviours were also assessed. RESULTS: Baseline resilience, diabetes-related distress and their interaction predicted physical health (HbA(1c)) at 1 year. Patients with low, moderate and high resilience were identified. Those with low or moderate resilience levels showed a strong association between rising distress and worsening HbA(1c) across time (r=.57, .56, respectively). However, those with high resilience scores did not show the same associations (r=.08). Low resilience was also associated with fewer self-care behaviours when faced with increasing distress (r=-.55). These correlation coefficients remained significant after controlling for starting-points. CONCLUSION: In patients with diabetes, resilience resources predicted future HbA(1c) and buffered worsening HbA(1c) and self-care behaviours in the face of rising distress levels.

Relations of caregiving stress and health depend on the health indicators used and gender.

Extensive research has evaluated relations between stress and health. These studies have varied in the type of stress examined (acute vs. chronic) and in the way in which health has been operationalized. Here we examine relations between chronic stress and 25 indicators of various health dimensions (e.g., physiological indexes, medical records, and self-reports of global health; symptoms, functional status, health service utilization, and psychosocial distress/quality of life). We also assessed whether such relations are moderated by gender, an individual difference variable that is important to health and longevity. Samples included 157 community-residing older adults (M age = 69.4 years, 31.8% men), approximately half of whom were caregivers for a spouse with Alzheimer's disease, and half were demographically similar noncaregiver spouses. Principal component analyses on the 25 health measures resulted in 5 factors that met standard criteria for acceptance. In women, caregivers reported worse physical health and psychological health than noncaregivers, but their physiological risk was similar. In men, caregivers had greater physiological risk, but they reported better physical health than did men noncaregivers. Researchers who study chronic stress and health should consider the possibility that the relation between chronic stress and health may vary for men and women depending on the type of health being assessed.

Associations among perceptions of social support, negative affect, and quality of sleep in caregivers and noncaregivers.

The authors used structural equation modeling to examine associations among perceptions of negative affect, social support, and quality of sleep in a sample of caregivers (n = 175) and noncaregiver control participants (n = 169). The authors hypothesized that caregiver status would be related to sleep quality directly and also indirectly by way of negative affect and social support. This hypothesis was partially supported in that caregiving was found to be indirectly related to sleep quality. However, after accounting for the indirect effects of negative affect and social support, the direct effect of caregiving on sleep quality was no longer statistically significant. The structural model accounted for approximately 43% of the variance in sleep quality. The present findings may be useful in the development of successful sleep interventions for caregivers.
