Family caregiving of persons with dementia: Prevalence, health effects, and support strategies

The authors summarize the dementia caregiving literature and provide recommendations regarding practice guidelines for health professionals working with caregivers. Family caregiving of older persons with disability has become commonplace in the United States because of increases in life expectancy and the aging of the population, with resulting higher prevalence of chronic diseases and associated disabilities, increased constraints in healthcare reimbursement, and advances in medical technology. As a result, family members are increasingly being asked to perform complex tasks similar to those carried out by paid health or social service providers, often at great cost to their own well-being and great benefit to their relatives and society as a whole. The public health significance of caregiving has spawned an extensive literature in this area, much of it focused on dementia caregiving because of the unique and extreme challenges associated with caring for someone with cognitive impairment. This article summarizes the literature on dementia caregiving, identifies key issues and major findings regarding the definition and prevalence of caregiving, describes the psychiatric and physical health effects of caregiving, and reviews various intervention approaches to improving caregiver burden, depression, and quality of life. Authors review practice guidelines and recommendations for healthcare providers in light of the empirical literature on family caregiving.

The Association of Late-Life Depression and Anxiety With Physical Disability: A Review of the Literature and Prospectus for Future Research

Depression and anxiety disorders are associated with excess disability. The authors searched the recent geriatric literature for studies associating late-life depression or anxiety with physical disability. Studies showed depression in old age to be an independent risk factor for disability; similarly, disability was found to be a risk factor for depression. Anxiety in late life was also found to be a risk factor for disability, although not necessarily independently of depression. Increased disability due to depression is only partly explained by differences in socioeconomic measures, medical conditions, and cognition. Physical disability improves with treatment for depression; comparable studies have not been done for anxiety. The authors discuss how these findings inform current concepts of physical disability and discuss the implications for future intervention studies of late-life depression and anxiety disorders.

Is it beneficial to involve a family member? A meta-analysis of psychosocial interventions for chronic illness.

Links between chronic illness and family relationships have led to psychosocial interventions targeted at the patients closest family member or both patient and family member. The authors conducted a meta-analytic review of randomized studies comparing these interventions with usual medical care (k=70), focusing on patient outcomes (depression, anxiety, relationship satisfaction, disability, and mortality) and family member outcomes (depression, anxiety, relationship satisfaction, and caregiving burden). Among patients, interventions had positive effects on depression when the spouse was included and, in some cases, on mortality. Among family members, positive effects were found for caregiving burden, depression, and anxiety; these effects were strongest for nondementing illnesses and for interventions that targeted only the family member and that addressed relationship issues. Although statistically significant aggregate effects were found, they were generally small in magnitude. These findings provide guidance in developing future interventions in this area.

Review and Meta-analysis of Couple-Oriented Interventions for Chronic Illness

BackgroundEvidence continues to build for the impact of the marital relationship on health as well as the negative impact of illness on the partner. Targeting both patient and partner may enhance the efficacy of psychosocial or behavioral interventions for chronic illness.PurposeThe purpose of this report is to present a cross-disease review of the characteristics and findings of studies evaluating couple-oriented interventions for chronic physical illness.MethodsWe conducted a qualitative review of 33 studies and meta-analyses for a subset of 25 studies.ResultsIdentified studies focused on cancer, arthritis, cardiovascular disease, chronic pain, HIV, and Type 2 diabetes. Couple interventions had significant effects on patient depressive symptoms (d = 0.18, p < 0.01, k = 20), marital functioning (d = 0.17, p < 0.01, k = 18), and pain (d = 0.19, p < 0.01, k = 14) and were more efficacious than either patient psychosocial intervention or usual care.ConclusionsCouple-oriented interventions have small effects that may be strengthened by targeting partners’ influence on patient health behaviors and focusing on couples with high illness-related conflict, low partner support, or low overall marital quality. Directions for future research include assessment of outcomes for both patient and partner, comparison of couple interventions to evidence-based patient interventions, and evaluation of mechanisms of change.

The Life Engagement Test: Assessing Purpose in Life

This article describes a 6-item scale, the Life Engagement Test, designed to measure purpose in life, defined in terms of the extent to which a person engages in activities that are personally valued. Psychometric data are presented including information about the scales factor structure, internal consistency, test-retest reliability, convergent validity, discriminant predictive validity, and norms. The data suggest that the Life Engagement Test is psychometrically sound across different gender, age, and ethnic groups and is appropriate for wider use. Discussion centers on the use of the Life Engagement Test in behavioral medicine and health psychology research and recent associations that have begun to emerge between the scale and health-relevant outcomes.

The course of functional decline in older people with persistently elevated depressive symptoms: longitudinal findings from the Cardiovascular Health Study.

Objectives: To examine the relationship between persistently high depressive symptoms and long‐term changes in functional disability in elderly persons.

Association of Enjoyable Leisure Activities With Psychological and Physical Well-Being

Objective: To examine whether engaging in multiple enjoyable activities was associated with better psychological and physiological functioning. Few studies have examined the health benefits of the enjoyable activities that individuals participate in voluntarily in their free time. Method: Participants from four different studies (n = 1399 total, 74% female, age = 19–89 years) completed a self-report measure (Pittsburgh Enjoyable Activities Test (PEAT)) assessing their participation in ten different types of leisure activities as well as measures assessing positive and negative psychosocial states. Resting blood pressure, cortisol (over 2 days), body mass index, waist circumference, and perceived physiological functioning were assessed. Results: Higher PEAT scores were associated with lower blood pressure, total cortisol, waist circumference, and body mass index, and perceptions of better physical function. These associations withstood controlling for demographic measures. The PEAT was correlated with higher levels of positive psychosocial states and lower levels of depression and negative affect. Conclusion: Enjoyable leisure activities, taken in the aggregate, are associated with psychosocial and physical measures relevant for health and well-being. Future studies should determine the extent that these behaviors in the aggregate are useful predictors of disease and other health outcomes. PEAT = Pittsburgh Enjoyable Activities Index; SBP = systolic blood pressure; DBP = diastolic blood pressure; BMI = body mass index; WC = waist circumference; SES = socioeconomic status..

Centrality of women's multiple roles: beneficial and detrimental consequences for psychological well-being.

Theorists have proposed that greater centrality (personal importance) of a social role is associated with better psychological well-being but that role centrality exacerbates the negative effects of stress in that same social role on well-being. The present study found evidence to support both hypotheses in a sample of 296 women who simultaneously occupied the roles of parent care provider, mother, wife, and employee. Greater centrality of all four roles was related to better psychological well-being. As predicted, wife centrality exacerbated the effects of wife stress on life satisfaction, and employee centrality exacerbated the effects of employee stress on depressive symptoms. Contrary to prediction, centrality of the mother role buffered women from the negative effects of mother stress on depressive symptoms. These findings point to an aspect of role identity that can benefit well-being but that has complex effects in the context of role stress.

The "Relative" Efficacy of Involving Family in Psychosocial Interventions for Chronic Illness: Are There Added Benefits to Patients and Family Members?

Specific interventions included in the review Studies were eligible if they compared family psychosocial, social or behavioural interventions with patient-orientated psychosocial interventions and enrolled complete patient-family dyads. Most of the included studies used cognitivebehavioural therapy/skills training or education plus support; other studies used education alone, blood-pressure monitoring in the home, and exercise and behavioural therapy. All but one of the interventions lasted between 5 weeks and 3 years; one intervention was conducted during transfer out of critical care.

Dementia patient suffering and caregiver depression.

Cross-sectional and longitudinal analyses were carried out to assess the relationship between dementia patient suffering, caregiver depression, and antidepressant medication use in 1222 dementia patients and their caregivers. We assessed the prevalence of 2 types of patient suffering, emotional and existential distress, and examined their independent associations with caregiver depression and antidepressant medication use when controlling for sociodemographic characteristics of caregivers and patients, cognitive and physical disability of the patient, the frequency of patient memory problems and disruptive behaviors, and the amount of time spent caring for the patient. Multiple linear regression models showed that both aspects of perceived patient suffering independently contribute to caregiver depression (emotional distress: β=1.24; P<0.001; existential distress: β=0.66; P<0.01) whereas only existential suffering contributes to antidepressant medication use: odds ratio=1.25 95% confidence interval, 1.10-1.42; P<0.01. In longitudinal analyses, increases in both types of suffering were associated with increases in caregiver depression (emotional distress: β=1.02; P<0.01; existential distress: β=0.64; P<0.01). This is the first study to show in a large sample that perceived patient suffering independently contributes to family caregiver depression and medication use. Medical treatment of patients that maintain or improve memory but do not address suffering may have little impact on the caregiver. Alzheimer disease patient suffering should be systematically assessed and treated by clinicians.
