The relationship between self-efficacy and positive aspects of caregiving in Alzheimer's disease caregivers

Objectives: Positive aspects of the caregiving experience may buffer caregivers from the many negative psychological and physical consequences of caregiving. Understanding what factors relate to the recognition of positive aspects of caregiving is important for the enhancement of caregiver well-being. Self-efficacy is a potentially modifiable psychological construct that has been associated with positive thinking, improved control of negative affect, and enhanced motivation.

Methods: This study examined the relationship between positive aspects of caregiving and self-efficacy among 57 family members caring for a loved one with Alzheimer's disease. Participant data was gathered through individual interviews conducted as a part of a larger randomized controlled trial of a caregiver intervention.

Results: We found that self-efficacy accounted for a significant percentage of the variance in positive aspects of caregiving after controlling for other factors commonly associated with positive aspects of caregiving including caregiver demographics, care recipient neuropsychiatric symptoms, and caregiver depression.

Conclusions: Our results suggest that high self-efficacy relates to caregivers’ perception of positive aspects of the caregiving experience.     

Positive aspects of caregiving: rounding out the caregiver experience

OBJECTIVES: To identify positive aspects of caregiving and examine how they are associated with caregiver outcomes. METHOD: This study used a national sample of caregivers derived from the Canadian Study of Health and Aging (part 2). Two hundred and eighty-nine caregivers caring for seniors living in the community were questioned about their experience of caregiving. Caregivers were asked whether they could identify any positive aspects related to their role, the type of positive aspects and to rate their feelings about caring. Using a conceptual model developed by Noonan and Tennstedt (1997), a staged stepwise multiple regression approach was used factoring the background/contextual variables, stressor variables (3 MS score, ADL limitations), mediator variables (positive aspects of caregiving, number of services used) and outcome variables (depression, burden and self-assessed health measures) into the model. RESULTS: Two hundred and eleven caregivers (73%) could identify at least one specific positive aspect of caregiving. An additional 20 (6.9%) could identify more than one positive aspect. Positive feelings about caring were associated with lower CES-D scores ( p<0.001), lower burden scores ( p<0.001) and better self assessed health ( p<0.001). CONCLUSION: Clinicians should inquire about the positive aspects of caregiving if they are to fully comprehend the caregiver experience and identify risk factors for negative caregiver outcomes.     

Socioecological factors and positive aspects of caregiving: findings from the REACH II intervention

Objective: Taking a socioecological perspective, this study assessed the relationship of intrapersonal, interpersonal, and organizational factors to positive aspects of caregiving (PAC) for 642 dementia caregivers by racial/ethnic group from the baseline data of the multisite Resources for Enhancing Alzheimer's Caregiver Health II (REACH II) intervention.

Methods: Nine intrapersonal indicators, 4 interpersonal indicators, and 12 organizational indicators were used. Blocked-multiple regression analyses by three racial/ethnic groups were computed to examine significant factors related to PAC among caregivers after controlling for memory and behavioral problems.

Results: Data showed a significant difference in PAC and significantly different indicators of PAC by racial/ethnic group. Hispanic caregivers reported the highest level of PAC while White participants showed the lowest scores on the measure of PAC. Education, marital status, and using formal transportation services were significant predictors for PAC among Hispanic caregivers; age, education, caregiving duration, and received social support were significant for PAC among African American caregivers; and sex, education, being a spousal caregiver, satisfaction with social support, using help from homemaker and visiting nurse services, and participating in support groups were significant among White caregivers.

Conclusion: Findings indicate that PAC varies significantly across the three studied racial/ethnic groups of family caregivers and that intrapersonal, interpersonal, and organizational factors relate uniquely to PAC. Additional investigations of PAC could serve an important role in the development of family caregiving supports and services.     

The relationship between family functioning and caregiving appraisal of dementia family caregivers: caregiving self-efficacy as a mediator

Objectives: The aim of this study was to explore caregiving self-efficacy as a mediator for the association between family functioning and caregiving appraisal of dementia family caregivers in Taiwan.

Method: This study adopted a cross-sectional correlational design. Purposive sampling was used to recruit 115 dyads of dementia patients and family caregivers from the outpatient neurological clinics of two hospitals in northern Taiwan. Data were gathered through interviews with a structured questionnaire, which included demographic characteristics for caregivers and patients, family functioning, caregiving self-efficacy, as well as positive and negative aspects of caregiving appraisal.

Results: Family functioning, patients' activities of daily living score, Neuropsychiatric Inventory caregiver distress, and three domains of self-efficacy were significantly associated with caregiver burden. Hierarchical multiple regression analyses indicated that self-efficacy for obtaining respite (SE-OR) significantly explained 20.5% of the variance in caregiver esteem. Caregiver perceived worsened health status, family functioning, and SE-OR significantly explained 59% of the variance in caregiver burden. The mediation test only supported the partially mediating role of SE-OR on the relationship between family functioning and caregiver burden, while the mediating effect of self-efficacy for responding to disruptive behaviours and controlling upsetting thoughts were insignificant.

Conclusion: Our findings provided preliminary evidence for health professionals recommending that future studies should assess the family dynamic and health problems of caregivers, and develop appropriate family-centred interventions that focus on strengthening interfamily support and respite services to alleviate caregiver burden.     

Caregiving burden and psychological distress in Chinese spousal caregivers: gender difference in the moderating role of positive aspects of caregiving

Objectives: This study endeavors to advance the current literature by examining the gender differences in the caregiving experiences and the stress-buffering role of positive aspects of caregiving (PAC) among Chinese spousal caregivers of frail elders in Hong Kong.

Method: Forty-nine husband caregivers and 121 wife caregivers of frail elders in Hong Kong (N = 170) responded to the Positive Aspects of Caregiving (PAC) scale, the Zarit Burden Interview (ZBI), the 21-item Depression, Anxiety, and Stress Scales (DASS-21), and demographic questions. These spousal caregivers were diverse in age, and their care receivers were diverse in terms of age and health condition.

Results: As predicted, there were significant gender differences in the moderating effects of PAC on the relationships of caregiving burden to depression, anxiety, and overall psychological distress. While PAC significantly buffered the effects of caregiving burden on depression, anxiety, and overall psychological distress for wife caregivers, the moderating effects of PAC were not significant for husband caregivers. Unexpectedly, wife caregivers reported lower PAC, higher caregiving burden, and higher psychological distress.

Conclusion: As these findings suggest that PAC is lower but more beneficial for Chinese wife caregivers than Chinese husband caregivers, helping professionals are recommended to use strengths-based interventions that target PAC when working with Chinese wife caregivers.     

The stroke caregiving trajectory in relation to caregiver depressive symptoms,burden, and intervention outcomes

Background: Caregiver depression and burden have a detrimental effect on stroke survivors’ rehabilitation and are contributors to stroke survivors’ hospital readmission and institutionalization. The stroke caregiving trajectory is unique compared to other illnesses, and the effect of length of caregiving on stroke caregiver outcomes is poorly understood. Interventions can improve caregiver outcomes, but the optimal timing of these interventions is unclear.

Objectives: We sought to determine the relationship between: (1) length of caregiving and stroke caregiver depressive symptoms and burden, and (2) length of caregiving and amount of change in depressive symptoms and burden following the Resources and Education for Stroke Caregivers’ Understanding and Empowerment (RESCUE) intervention – an online and telephone problem-solving, education, and support intervention.

Methods: We analyzed retrospective data collected from 72 stroke caregivers who participated in the RESCUE intervention. Outcomes were caregiver depressive symptoms and burden. Data were analyzed using mixed-effects regression analysis.

Results: Baseline depressive symptoms and burden were both negatively related to length of caregiving (p < 0.05). We found significant improvement in caregiver depressive symptoms and burden following an intervention. The interaction between changes in outcomes and length of caregiving was not significant for either depressive symptoms (p = 0.26) or burden (p = 0.10).

Conclusions: This study contributes to the understanding of the relationship between length of caregiving and depression, burden, and intervention outcomes. Clinicians should recognize that the stroke caregiving trajectory can be nonlinear. Routine and repeated clinical assessment of caregiver well-being is needed, along with implementation of interventions when necessary, regardless of how much time has passed since the stroke.     

The comparison of burden between caregiving spouses of depressive and demented patients

BACKGROUND: The opportunities for a depressive or demented elderly patient to live at home are dependent on the availability of support. If the spouse is alive, her or his resources to care for the patient are an essential option. In this study we compared the burden of the spouses of depressive and demented elderly patients admitted to the University Psychogeriatric Clinic. METHODS: The Zarit Burden Interview was used when comparing the burden between the groups. Psychological distress was screened by the 12-item General Health Questionnaire. The care and support given by the spouse was assessed by Involvement Evaluation Questionnaire. The spouse's stress related to the health state of the patient was evaluated by the Pearlin Caregiving Stress Inventory. Twenty-two spouses living with a depressive patient and 43 with a demented patient were included in the study. RESULTS: The spouses of demented patients as a group were psychologically more stressed than the spouses of depressive patients. However, when demented patients were divided into two groups, in those admitted mainly for noncognitive symptoms related to dementia and in those admitted for memory assessment and diagnostic purposes, the burden of the spouses in the former group was higher than that of the group of depressive patients' spouses. No difference was found between the latter group of demented patient spouses and depressive patients' spouses. Both the patients and the spouses in the demented group were older than those in the depressive group. However, no correlation was found between stress of the spouse and her or his own age or the age of the patient either within the depressive or within the demented group. As expected, the function level of demented patients was lower than that of depressive patients. A correlation was found within both groups between low functional capacity of the patient and the stress of the spouse. In both groups the spouses who felt their own mental health to be poor were more likely to have high levels of burden. CONCLUSIONS: Among the general psychogeriatric patient groups, the caregiving spouses of demented patients with noncognitive psychiatric symptoms are the most burdened group. However, spouses of depressive patients are as much burdened as those of demented patients with mild to moderate memory impairment. More support is needed for every spouse group caring for psychogeriatric patients.     

Caregiving burden and psychiatric morbidity in spouses of persons with mild cognitive impairment

BACKGROUND: While the deleterious psychosocial and mental health effects of dementia caregiving are firmly established, very little is known about the burdens or psychiatric outcomes of providing care to a spouse with less severe cognitive impairment, such as mild cognitive impairment (MCI). We characterized the nature and level of caregiver burden and psychiatric morbidity in spouses of persons diagnosed with MCI. METHODS: Interview assessments were completed on a cohort of 27 spouses of persons with a recent diagnosis of MCI. Patient medical records were reviewed to collect information regarding the MCI patient's medical history. RESULTS: Respondents endorsed elevated levels of both task-related responsibilities and subjective caregiver burden. Depression and anxiety symptom levels also showed some elevations. Measures of caregiver burden were significantly associated with depression and anxiety levels. In particular, even after controlling for demographic risk factors for distress, nursing task burden was correlated with elevated depressive symptoms, and greater lifestyle constraints were correlated with higher anxiety levels. CONCLUSIONS: Although caregiver burden and psychiatric morbidity levels were lower than those typically observed in family dementia caregiving samples, our findings suggest that MCI caregivers have already begun to experience distress in association with elevated caregiving burden. These individuals may be ideal targets for selective preventive interventions to maximize their psychological well-being as caregiving burdens related to their spouses' cognitive impairment increase.     

Association between cultural factors and the caregiving burden for Chinese spousal caregivers of frail elderly in Hong Kong

Objectives: The aim of this study was to explore the relationship between cultural factors and the caregiving burden of Chinese spousal caregivers who provided care to their frail partners.

Method: A sample consisting of 102 Chinese caregivers for frail elderly spouses was recruited from home care services across various districts in Hong Kong. Structured interviews were conducted with the participants in their homes, measuring demographics, the functional status of the spouse, the degree of assistance required in daily care, perceived health, the caregiver's orientation to traditional Chinese family values, social support, coping, and caregiver burden.

Results: Findings of regression analysis indicated that gender, activities of daily living (ADL) status, orientation to traditional Chinese family values, passive coping, and marital satisfaction associated with caregiver burden. Being female, having lower functioning in ADL or a strong orientation toward traditional Chinese family values, employing the strategies of passive coping more frequent, or experiencing a low degree of marital satisfaction were associated with high levels of caregiver burden.

Conclusion: These findings provided a basis for developing appropriate interventions to minimize the caregiver burden of spousal family caregivers.     

Trajectories of positive aspects of caregiving among family caregivers of stroke-survivors: the differential impact of stroke-survivor disability

Objective To delineate positive aspects of caregiving trajectories among family caregivers of stroke-survivors and determine the impact of stroke-survivor disability, a time-varying factor, on the delineated trajectories.

Methods In a longitudinal study, family caregivers of 173 stroke-survivors in Singapore were administered the Positive Aspects of Caregiving scale (PAC scale) thrice (baseline/3 months/6 months). Group-based trajectory modeling delineated positive aspects of caregiving trajectories and identified the impact of stroke-survivor disability on the trajectories.

Results Two distinct positive aspects of caregiving trajectories, Persistently Low and Persistently High were delineated. Increase in stroke-survivor disability was associated with a significant downward shift (reduction in positive aspects of caregiving) of the Persistently Low trajectory and a significant upward shift (increase in positive aspects of caregiving) of the Persistently High trajectory. Older caregivers were more likely to follow the Persistently High trajectory.

Conclusions Care professionals should be mindful of the heterogeneity in the longitudinal pattern of positive feelings resulting from care provision among family caregivers of stroke-survivors, and the differential impact of stroke-survivor disability on the pattern of positive feelings. Younger caregivers as well as family caregivers who have low positive feelings at the start of their caregiver journey and experience worsening functional disability of their care recipient (stroke-survivor) require greater attention and support.     

The moderating effect of religiosity on caregiving burden and depressive symptoms in caregivers of patients with dementia

Objectives: This study explored whether religiosity/spirituality has a protective role against negative caregiving outcomes, in a large multicenter nationwide sample of caregivers of patients with dementia in South Korea. Additionally, this study was the first to examine whether religiosity/spirituality could affect caregiving outcomes according to the various religious affiliations of caregivers.

Methods: The study was conducted on a sample of 476 caregivers of patients with dementia participated in the Clinical Research Center for Dementia of South Korea (CREDOS). We examined the moderating effect of each of the three dimensions of religiosity/spirituality (organizational religious activity, ORA; non-organizational religious activity, NORA; intrinsic religiosity, IR) on the relationship between activities of daily living (ADL) of patients with dementia and caregiving burden and depressive symptoms of caregivers, using a series of hierarchical regression analyses. In addition, these analyses were conducted according to the religious affiliations of the caregivers.

Results: ORA, NORA, and IR of religiosity/spirituality alleviated the effect of ADL of patients on caregiving burden. ORA and IR moderated the relationship between ADL of patients and depressive symptoms of caregivers. These moderating effects of religiosity on caregiving outcomes were different according to various religious groups.

Conclusion: We have identified religiosity/spirituality as a protective factor for caregivers of patients with dementia. The sub-dimensions of religiosity as moderators were different by religious affiliations of caregivers. Further studies are needed to investigate the specific religiosity-related factors which could positively impact the mental health of the caregivers of patients with dementia by religions.     

Association of physical functioning of persons with dementia with caregiver burden and depression in dementia caregivers: an integrative data analysis

Objectives: To determine whether caregiver relationship and race modify associations between physical functioning of persons with dementia (PWD) and their caregiver's burden and general depressive symptoms.

Method: We pooled data from four behavioral intervention trials (N = 1,211). Using latent growth modeling, we evaluated associations of PWD physical functioning with the level and rate of change in caregiver burden and caregivers' general depressive symptoms and stratified these associations by caregiver relationship and race.

Results: PWD were, on average, 81 years old (68% female) with mean follow-up of 0.5 years. More baseline PWD physical impairment was associated with less worsening in caregiver burden over time (β = ?0.23, 95% CI: ?0.29, ?0.14), but this relationship was not modified by caregiver characteristics. More impaired baseline PWD physical functioning was not associated with changes in depressive symptoms (β = ?0.08, 95% CI: ?0.17, 0.00), but was associated with less worsening in depressive symptoms among spousal (β = ?0.08, 95% CI: ?0.17, 0.00) and non-white (β = ?0.08, 95% CI: ?0.17, 0.00) caregivers.

Conclusions: Dementia caregivers may experience reduced caregiver-related burden because of adjustment to PWD functional status, while spousal and non-white caregivers may experience less depressive symptoms resultant of adjustment to functional status.     

Dynamic process of family burden in dementia caregiving: a new field for psychotherapeutic interventions

Families caring for a patient with dementia are prone to significant physical, psychological and social stress. It is now well established that the caregiver burden does not only negatively affect the caregiver's physical and mental health, but is also associated with an increase in behavioural and psychiatric symptoms of dementia. Burden determinants include the quality of the relationship between the patient and caregiver; patient variables, such as the need to manage the behavioural and psychological symptoms of dementia; and also caregiver variables, such as the satisfaction of caring, demographic characteristics and societal roles. The standardised assessment of interventions for caregivers in dementia care remains a difficult task. In recent years, family interventions that focus on the process of burden itself in relation to the caregiver's subjective experience of personal growth and enrichment have been proposed. This new approach is based on the identification of tasks and challenges faced by family members throughout the different stages of the disease. In this context, brief crisis interventions transform periods of disorganisation experienced by the family into opportunities for change, whereas rehabilitation interventions developed by professional caring networks offer a continuous assessment and advice to the family. This article provides a critical review of the consequences and determinants of caregiver burden in dementia care with special reference to the emerging notion of the caregiver's subjective experience in the context of family processes.     

The effect of coping on the caregiver of elderly patients with dementia

Abstract Ninety-eight caregivers of elderly patients with cognitive impairment were surveyed by questionnaires in order to examine the relationship between their coping strategies and subjective burden. Confrontative coping and avoidance coping were significantly associated with their burden. The severity of cognitive impairment and the behavioral problems of the patients were also significantly associated with the caregivers' burden. However, a multiple regression analysis suggested that the caregivers' coping strategies may be more important than the patients' condition in terms of the effects on the burden.
