Psychometric properties of an abridged version of The Zarit Burden Interview within a representative Canadian caregiver sample

Systematic review following COSMIN guidelines: Short forms of Zarit Burden Interview

This comprehensive review assessed the psychometric properties of abbreviated versions of the Caregiver Burden Instrument (ZBI-22). Initially, 40 articles that met the inclusion criteria were identified through a systematic search of four databases. Additionally, 26 articles were included through manual searches, totaling 66 articles in the analysis. Different versions of instruments measuring caregiver burden were examined, considering item variability and differences in factor structures. Although most measures exhibited satisfactory content validity, as well as construct validity supported by high internal consistencies, it is important to note that measurement invariance, criterion validity and test-retest reliability were not established for all measures analyzed. Furthermore, structural validity was not satisfactory for all versions. Research and clinical practice could benefit from a standardized approach that allows for a more accurate and consistent assessment of caregiver strain.

Self-Assessment Instruments for Supporting Family Caregivers: An Integrative Review

Family caregivers take on a variety of tasks when caring for relatives in need of care. Depending on the situation and the intensity of care, they may experience multidimensional burdens, such as physical, psychological, social, or financial stress. The aim of the present study was to identify and appraise self-assessment instruments (SAIs) that capture the dimensions of family caregivers' burdens and that support family caregivers in easily identifying their caregiving role, activities, burden, and needs. We performed an integrative review with a broad-based strategy. A literature search was conducted on PubMed, Google Scholar, Google, and mobile app stores in March 2020. After screening the records based on the eligibility criteria, we appraised the tools we found for their usefulness for family care and nursing practice. From a total of 2654 hits, 45 suitable SAIs from 274 records were identified and analyzed in this way. Finally, nine SAIs were identified and analyzed in detail based on further criteria such as their psychometric properties, advantages, and disadvantages. They are presented in multi-page vignettes with additional information for healthcare professionals. These SAIs have proven useful in assessing the dimensions of caregiver burden and can be recommended for application in family care and nursing practice.

Family dementia caregivers with suicidal ideation improve with mentalizing imagery therapy: Results from a pilot study

Background

Family caregivers of persons living with dementia often experience increased depression and suicidal ideation (SI). However, the feasibility and impact of therapies on caregiver SI has remained largely unexplored. Mentalizing imagery therapy (MIT) helps reduce psychological symptoms through mindfulness and guided imagery. This pilot study examined the feasibility of participation by caregivers with SI in a randomized controlled trial (RCT) of MIT versus a psychosocial support group (SG), and the respective impact of group on SI, depression, and secondary outcomes.

Methods

A secondary analysis of data from an RCT of 4-week MIT or SG for caregivers (n = 46) was performed, identifying SI (n = 23) and non-SI (n = 23) cohorts. Group attendance and home practice were compared between cohorts. In the SI cohort (total n = 23, MIT n = 11, SG n = 12), group differences in SI, depression, and secondary outcomes were evaluated post-group and at 4-month follow-up.

Results

Attendance in both groups and home practice in MIT were similar between SI and non-SI cohorts. In the SI cohort, MIT evinced greater improvements relative to SG in SI (p=.02) and depression (p=.02) post-group, and other secondary outcomes at follow-up.

Limitations

Limitations include small sample size and single-item assessments of SI from validated depression rating scales.

Conclusions

Participation in an RCT was feasible for caregivers with SI. MIT resulted in important benefits for SI and depression, while SG showed no acute SI benefit. The role of MIT in improving SI should be confirmed with adequately powered trials, as effective therapies to address caregiver SI are critical.

Caregiver burden and COVID-19: How epilepsy caregivers experienced the pandemic

INTRODUCTION

Caregivers of adults with epilepsy face unique challenges, yet most studies focus on the impact of epilepsy on those living with the condition, rather than the impact on caregivers. Our objective was to evaluate whether caregivers' pandemic-related changes and experiences - namely those related to their health, healthcare access, and well-being - were associated with their caregiving burden.

METHODS

Caregivers of adults with epilepsy (n = 261) were recruited through Qualtrics Panels to participate in an online survey examining health, well-being, COVID-19 experiences, and caregiver burden from October-December, 2020. The burden was measured using the Zarit 12-item measure; the clinically significant burden was defined as a score greater than 16. Adjustments were made to account for burden scores related to exposures of interest. Chi-square tests, t-tests, and generalized linear regression models were used to compare cross-sectional associations between COVID-19 experiences and burden.

RESULTS

Over half (57.9%) of caregivers had clinically significant caregiver burden. Most reported increased anxiety (65%), stress (64%), and sense of social isolation (58%) during the pandemic. Many caregivers reported that their sense of control over their life (44%) and their use of healthcare changed (88%) due to COVID-19. In adjusted models, caregivers who reported increased anger, increased anxiety, decreased sense of control, or changes in healthcare utilization during COVID-19 had about twice the odds of having clinically significant caregiver burden compared to caregivers who did not report changes.

DISCUSSION

Changes experienced by caregivers of adults with epilepsy during the pandemic were strongly associated with clinically significant levels of caregiver burden. These findings demonstrate the link between mass-level events, such as a pandemic, the burden caregivers of adults with epilepsy may carry, and subsequent psychological outcomes.

CONCLUSION

Caregivers of adults with epilepsy may need support to reduce the negative impact of COVID-19-related experiences and should be connected to healthcare and resources that can help alleviate their burden.

Caring again: Support for parent caregivers of wounded, ill, and/or injured adult children veterans

BACKGROUND

Parents often provide care to adult children veterans with polytrauma, traumatic brain injury, and/or post-traumatic stress disorder.

OBJECTIVE

This two-arm randomized clinical trial compared interventions to help parent caregivers improve their depression, anxiety, and burden and manage care by decreasing troubling and concerning behaviors.

METHODS

Interventions were six one-hour structured one-on-one behavioral sessions (REACH) or six 30-minute prerecorded online educational webinars. Both focused on knowledge, strategies for care, and coping, but REACH sessions were targeted, interactive, and skills-based. Quantitative and qualitative data were collected by telephone. Quantitative analyses included chi-squared test or independent samples t-test and repeated measures mixed linear modeling, with theme development for qualitative data.

RESULTS

There were 163 parent caregivers, mostly mothers. During six months, participants in both arms improved significantly in depression, anxiety, burden, and reported veteran troubling and concerning behaviors. REACH caregivers showed a group by time improvement in concerning behaviors. Benefits included resources, self-reflection, not feeling alone, new skills, improved self-efficacy, and helping others. Specific concerns include exclusion from military and veteran care briefings and concern for the future.

CONCLUSION

The positive response to both interventions provides opportunities for organizations with varying resources to provide support for parent caregivers. Interventions need to be targeted to parents' particular concerns and needs.

Are caregiving appraisal and relationship quality key mediators in informal caregiving burnout? A structural equation modelling study in Belgium and France

Informal caregivers are key players in maintaining chronically ill patients at home but often experience negative consequences such as informal caregiver burnout. The processes by which determinants related to informal care and their personal and social resources affect the caregiver's risk of burnout remains little investigated. Recent theoretical works have suggested that two mediators could play an important role in understanding how these risks and resources influence informal caregiver burnout: by deteriorating how they view their role (caregiving appraisal) and by weakening the relationship with the care-recipient (relationship quality). The present study aimed at exploring the impact of the care-recipient's dependency (WHODAS), the caregiver's emotional intelligence (TEIQue-SF), and loneliness (UCLALS) on informal caregiver burnout (MBI-ICg). This association was explored both directly and through the mediation of caregiving appraisal (measured by subjective burden, ZBI) and relationship quality. To do so, a sample of 444 French-speaking informal caregivers completed online questionnaires from November 2017 to August 2018. Structural equation modelling (SEM) was performed to test the mediation model. As a result, the caregiving appraisal appears as a key mediator between determinants and informal caregiver burnout, whereas the relationship quality had a lower predictive value. Among the determinants, emotional intelligence was the strongest protective factor and the care-recipient's dependency was the strongest risk factor. But beyond this association, the perception informal caregivers have of their role (their caregiving appraisal) is a key mediator between these determinants and informal caregiver burnout, which emphasizes the importance of subjectivity in building risk and protective profiles.

Lower activity linkage between caregivers and persons with neurodegenerative diseases is associated with greater caregiver anxiety

Physiological linkage refers to the degree to which two individuals' central/peripheral physiological activities change in coordinated ways. Previous research has focused primarily on linkage in the autonomic nervous system in laboratory settings, particularly examining how linkage is associated with social behavior and relationship quality. In this study, we examined how linkage in couples' daily somatic activity (e.g., synchronized movement measured from wrist sensors)-another important aspect of peripheral physiology-was associated with relationship quality and mental health. We focused on persons with neurodegenerative diseases (PWNDs) and their spousal caregivers, whose linkage might have direct implications for the PWND-caregiver relationship and caregiver's health. Twenty-two PWNDs and their caregivers wore wristwatch actigraphy devices that provided continuous measurement of activity over 7 days at home. PWND-caregiver activity linkage was quantified by the degree to which activity was "in-phase" or "anti-phase" linked (i.e., coordinated changes in the same or opposite direction) during waking hours, computed by correlating minute-by-minute activity levels averaged using a 10-min rolling window. Caregivers completed well-validated surveys that assessed their mental health (including anxiety and depression) and relationship quality with the PWND. We found that lower in-phase activity linkage, but not anti-phase linkage, was associated with higher caregiver anxiety. These dyad-level effects were robust, remaining significant after adjusting for somatic activity at the individual level. No effects were found for caregiver depression or relationship quality. These findings suggest activity linkage and wearables may be useful for day-by-day monitoring of vulnerable populations such as family caregivers. We offered several possible explanations for our findings.

Neurological patient and informal caregiver quality of life, and caregiver burden: A cross-sectional study of postdischarge community neurological nursing recipients

BACKGROUND

Neurological conditions produce considerable disease burden.

AIMS

To describe quality of life in patients with neurological conditions and informal caregivers receiving postdischarge generic community neurological nursing services, and caregiver burden.

METHOD

A descriptive cross-sectional design was used with researchers administering the WHOQOL-BREF Australian Version questionnaire and Zarit Burden Interview.

RESULTS

Most patients and caregivers rated quality of life as 'Good'. The patients' physical, psychological and environment domain scores, and caregivers' physical domain scores, were below norms. Half of the caregivers experienced burden and 42% had risk for depression.

CONCLUSION

A heterogeneous group of patients with neurological conditions had considerable care and support needs for fundamental functioning postdischarge. Quality of life and caregiver burden measures highlight the impact of their circumstances on their health and wellbeing. Research is warranted to determine a comprehensive set of generic needs to guide integrated community nursing services for building patient and caregiver self-management capacity.

Psychometric Properties of the Zarit Burden Interview in Informal Caregivers of Persons With Intellectual Disabilities

Intellectual disability leads to a loss of autonomy and a high level of dependence, requiring support from another person permanently. Therefore, it is necessary to incorporate the assessment of caregiver burden in healthcare actions, to avoid putting the health of caregivers and patients at risk. In this sense, the study aimed to analyze the internal structure of the Zarit Burden Interview (ZBI) in a sample of caregivers of people with intellectual disabilities, to provide convergent and discriminant evidence with a measure of the risk of maltreatment, and to estimate the reliability of the scores from the Classical Test Theory and the Rasch Measurement Theory. The study was instrumental. The sample consisted of 287 Peruvian informal primary caregivers of persons diagnosed with intellectual disabilities. To collect validity evidence, the internal structure (confirmatory factor analysis, CFA) and the relationship with other variables (convergent and discriminant evidence) were used, while reliability was estimated through the omega coefficient and Rasch analysis. The internal structure of the ZBI corroborated a unidimensional structure. In terms of convergent and discriminant evidence, the scale presents adequate evidence. Reliability levels were also good. Previously, the psychometric properties of the ZBI have not been studied in caregivers of people with intellectual disabilities, and it represents the first study of the scale in Peru. The results obtained will allow the use of this scale to design actions in the work with caregivers and studies to understand the psychology of the caregiver.

Caregiver Burden and Dementia: A Systematic Review of Self-Report Instruments

Background: As the demand for dementia care grows rapidly worldwide, heavy “caregiver burden” has been associated with stress and depression. Even so, standard metrics for interdisciplinary research of caregiver burden are limited. Objective: The objective of the present review is to recommend valid, reliable, and comprehensive self-report instruments of caregiver burden. Methods: A systematic review was performed using four databases, searched in April 2021. Articles that established or evaluated self-report instruments for dementia caregiver burden were included, while studies that involved non-dementia caregivers or did not clearly define caregiver burden were excluded. Established guidelines for reliability and agreement studies were used to assess quality and risk of bias. Assessments of self-report instruments were made based on reliability, validity, feasibility, and quality of psychometric evaluations, and comparative evaluations were presented in visual form using radar graphs. Results: Search terms yielded 1,720 articles, and 40 were included in the systematic review after excluding those of low quality. Based on the results of these studies, we recommend the Zarit Burden Interview, Screen for Caregiver Burden, Caregiver Burden Interview, and Burden Scale for Family Caregivers, due to their validity, reliability, and inclusion of multiple subjective and objective dimensions of burden. Conclusion: Targeting specific sources of caregiver burden can help prevent negative outcomes for both dementia patients and caregivers. Future studies should apply self-report instruments to measure and address caregiver burden longitudinally.

Mentalizing imagery therapy for depressed family dementia caregivers: Feasibility, clinical outcomes and brain connectivity changes

Background

Family dementia caregivers experience high rates of depression and anxiety that often go untreated due to time demands. We aimed to determine the feasibility of a brief, 4-week Mentalizing Imagery Therapy intervention, which couples mindfulness with guided imagery practices aimed at bolstering mentalizing capacity, to reduce caregiver psychological symptoms and to explore potential impact on dorsolateral prefrontal cortex connectivity.

Methods

Twenty-four family dementia caregivers with moderate depression symptoms (a score of 10 in Patient Health Questionnaire-9) were assigned to either group Mentalizing Imagery Therapy (MIT, n = 12) or a waitlist augmented by optional relaxation exercises (n = 12). Participants completed questionnaires to measure depression and anxiety at baseline and followup, and those eligible also underwent resting state functional magnetic resonance (fMRI) brain imaging at these time points.

Results

Eleven of 12 caregivers assigned to MIT completed the intervention and attended weekly groups 98% of the time. MIT home practice logs indicated average practice of 5 ± 2 sessions per week for 23 ± 8 min per session. All participants in waitlist completed the post-assessment. MIT participants exhibited significantly greater improvement than waitlist on self-reported depression and anxiety symptoms (p<.05) after 4 weeks. Neuroimaging results revealed increased dorsolateral prefrontal cortex connectivity with a putative emotion regulation network in the MIT group (p = .05) but not in waitlist (p = 1.0).

Limitations

Sample size limitations necessitate validation of findings in larger, randomized controlled trials.

Conclusions

A 4-week group MIT program was feasible for caregivers, with high levels of participation in weekly group meetings and home practice exercises.

Zarit burden interview among caregivers of community-dwelling older adults in a caribbean setting (Jamaica): Reliability and factor structure

The Zarit Burden Interview has been the most popularly used tool for measuring caregiver burden and with the 60 years and over population in Jamaica and developing countries expected to increase, caregiver burden and its assessment assume increased importance. Establishing the reliability and underlying factor structure of instruments such as the ZBI is critical. This study sought to determine the reliability of the Zarit Burden Interview and to assess its underlying factor structure. The ZBI was administered to 180 caregivers of community dwelling older persons in Jamaica in a nationally representative sample across four geographic health regions in 2016. The factor structure was identified using exploratory factor analysis (EFA) with Varimax rotation. Cronbach's alpha was used to assess internal consistency/reliability of the instrument. The internal consistency/reliability of the ZBI instrument was high (Cronbach's α = 0.859) and the corrected item-total correlations ranged from 0.134 to 0.730. The ZBI mean score was found to be 16.92 ± 12.04. EFA produced a six-factor model comprised of 19 items which explained 48.97% of total variance, and was subsequently reduced to four (37.27% of total variance) via the use of parallel analysis and scrutiny of confidence intervals. The four factors identified were 'personal strain', 'social relations disruption', 'resource strain/imbalance' and 'role intensity'. The ZBI-22 tool is a reliable instrument for evaluating caregiver burden among community dwelling older persons in Jamaica. A four factor model has emerged providing greater insights on the underlying constructs of the ZBI, the most widely used caregiver burden assessment tool.

Caregiver burden and associated factors amongst carers of women with advanced breast cancer attending a radiation oncology clinic in Nigeria

BACKGROUND

The responsibility of caring for patients with advanced cancer in sub-Saharan Africa is mostly shouldered by family members because of paucity of institutional facilities. There is a growing concern that the number of women needing treatment for advanced breast cancer is rising at an unprecedented rate in Nigeria.

AIM

To assess the caregiver burden and its associated factors amongst family caregivers of women with advanced breast cancer.

SETTING

The study was conducted at the radiation oncology clinic of the University College Hospital, Ibadan, Nigeria.

METHODS

A cross-sectional descriptive study was conducted amongst 157 eligible family caregivers of women with advanced breast cancer. The family caregivers completed an interviewer-administered questionnaire, which included the socio-demographic data, the caregiving process and the Zarit Burden Interview (ZBI). Logistic regression was used to identify factors, and ethical approval was obtained.

RESULTS

Over half (53%) of the respondents were males with spousal caregivers dominantly constituting 27.4% of all respondents, closely followed by daughters (25.5%) of the care recipients. The mean ZBI score was 29.84 ± 13.9. Most (72%) of the caregivers experienced burden. Factors associated with caregiver burden were previous hospitalisation of the care recipient (odds ratio [OR] = 3.74, confidence interval [CI]: 1.67 to 8.38) and perceived dysfunction in patients activities of daily living (OR = 2.57, CI: 1.14 to 5.78).

CONCLUSION

Family caregivers of women with advanced breast cancer experience burden of care. Recognition of this vulnerable population and the care recipient as a dyad is a sine qua non in mitigating the burden associated with their caregiving role.

High-Skilled vs. Low-Skilled Migrant Women: the Use of Competencies and Knowledge—Theoretical and Political Implications: an Example of the Elderly Care Sector in Poland

This paper presents the influx of migrants into the elderly care sector in Poland, which, until recently, has been perceived as a country that “exports” caregivers. It describes the results of 31 individual in-depth interviews conducted with immigrant women who take care of elderly in Poland. The purpose of the study was to determine the profile of an immigrant taking up work in the elderly care sector, including the specification of their education level and competencies. It was determined that 55% of the respondents have higher education, including over 20% with a degree in nursing or physiotherapeutic education. It was established that, when analysing migrants in the care sector, it seems necessary not to divide migrants based on their education level (high- vs. low-skilled), but rather to consider the education profile as a whole (general and special profile education). Women with specialised education differ from the other migrants in regard to their better labour market position (higher remuneration, legal employment) and the scope of skill usage. The comparison of high-skilled and low-skilled workers in the care sector is very useful from the perspective of policymakers due to the fact that there is an issue of over-qualification in Poland. The article contributes to the literature, especially research dealing with brain waste, as there is theoretical and empirical gap in research on the differences between high-skilled and low-skilled migrants working in elderly care.

Rates and prospective psychosocial correlates of pre-loss grief in cancer and dementia family members

This study examined changes in Pre-Loss Grief (PLG) among individuals whose family member has a life limiting illness and how baseline psychosocial factors predicted PLG. This two-wave study recruited family members of advanced cancer ( N = 100) and dementia ( N = 38) patients. A subsample completed 1-month follow-up (Cancer = 33; Dementia = 28). Higher caregiver burden and female participants predicted greater PLG at follow-up, accounting for baseline PLG. Family members of dementia patients (10.5%) were significantly more likely than family members of cancer patients (2.1%) to be in the “severe PLG” group. Findings demonstrate psychosocial factors related to PLG, informing interventions aimed at reducing PLG.

Feasibility and acceptability of a telephone and web-based stroke caregiver intervention: a pilot randomized controlled trial of the RESCUE intervention

OBJECTIVE

Assess the feasibility and acceptability of an Internet and telephone support and problem-solving intervention for stroke caregivers.

DESIGN

Randomized controlled pilot trial with four arms: four-week intervention (n = 13), eight-week intervention (n = 13), eight-week attention control (n = 13), and standard care (n = 14).

SETTING

Southeastern U.S. Veterans Health System.

PARTICIPANTS

Informal caregivers of Veterans who suffered a stroke in the preceding 2.5 years were enrolled over an 18-month period.

INTERVENTIONS

Intervention participants received RESCUE, a support and problem-solving intervention delivered via telephone and Internet by registered nurses. Attention control participants received active listening with no advice delivered by nurses via telephone.

MAIN MEASURES

Feasibility of a larger trial was assessed via recruitment and retention. Acceptability was assessed using an adapted enactment tool and qualitative interviews. Changes in caregiver depressive symptoms and burden were measured by the Center for Epidemiologic Studies Depression Scale and Zarit Burden Interview. The study was not powered for significance testing.

RESULTS

Of 340 eligible caregivers, 53 (16%) agreed to participate. Among those enrolled, 51 (96%) completed the study. Caregiver mean age was 60.3 (10.1), 49 (93%) were female and 36 (68%) were white. At baseline, 21 (39%) caregivers had high risk of depression and 18 (33%) had significant burden. Acceptability and enactment tool findings indicated positive participant responses to the intervention. Most rated the amount of sessions the "right amount". Qualitative analysis revealed the intervention was valued by and acceptable to caregivers.

CONCLUSIONS

Findings indicate the RESCUE intervention is feasible and acceptable to caregivers and warrants further testing.

Measurement Properties of the CAPACITY Instrument to Assess Perceived Communication With the Health Care Team Among Care Partners of Patients With Cognitive Impairment

BACKGROUND

The CAregiver Perceptions About CommunIcaTion with Clinical Team members (CAPACITY) instrument measures how care partners perceive themselves to be supported by the patient's health care team and their experiences communicating with the team.

OBJECTIVES

The objective of this study was to assess the measurement properties (ie, structural validity of the construct and internal consistency) of the CAPACITY instrument in care partners of patients with cognitive impairment, and to examine whether care partner health literacy and patient cognitive impairment are associated with a higher or lower CAPACITY score.

RESEARCH DESIGN

This was a retrospective cohort study.

SUBJECTS

A total of 1746 dyads of community-dwelling care partners and older adults in the United States with cognitive impairment who obtained an amyloid positron emission tomography scan.

MEASURES

The CAPACITY instrument comprises 12 items that can be combined as a total score or examined as subdomain scores about communication with the team and care partner capacity-assessment by the team. The 2 covariates of primary interest in the regression model are health literacy and level of cognitive impairment of the patient (Modified Telephone Interview Cognitive Status).

RESULTS

Confirmatory factor analysis showed the CAPACITY items fit the expected 2-factor structure (communication and capacity). Higher cognitive functioning of patients and higher health literacy among care partners was associated with lower communication domain scores, lower capacity domain scores, and lower overall CAPACITY scores.

CONCLUSIONS

The strong psychometric validity of the CAPACITY measure indicates it could have utility in other family caregivers or care partner studies assessing the quality of interactions with clinical teams. Knowing that CAPACITY differs by care partner health literacy and patient impairment level may help health care teams employ tailored strategies to achieve high-quality care partner interactions.

Development and Validation of Caregiver Risk Evaluation (CaRE): A New Algorithm to Screen for Caregiver Burden

Objective: The main objective was to develop a decision-support tool to assess the risk of caregiver burden, the Caregiver Risk Evaluation (CaRE) algorithm. Methods: Home care clients were assessed using the Resident Assessment Instrument for Home Care (RAI-HC). Their caregiver completed the 12-item Zarit Burden Interview (ZBI), the main dependent measure, which was linked to the RAI-HC. Results: In the sample (n = 344), 48% were aged 85+ years and 61.6% were female. The algorithm can be collapsed into four categories (low, moderate, high, and very high risk). Relative to the low-risk group, clients in the very high-risk group had an odds ratio of 5.16 (95% confidence interval: [2.05, 12.9]) for long-term care admission, after adjusting for client age, sex, and regional health authority. Discussion: The CaRE algorithm represents a new tool to be used by home care clinicians as they proactively plan for the needs of clients and their caregivers.

Direct and indirect predictors of burden among Bedouin caregivers of family members with terminal cancer in Israel

Objective: The diverse demands of cancer care, which require time, psychological, physical, and material resources, often lead to caregiver burden. Studies with caregivers from ethnic minority groups suggest that they have unique beliefs and may experience different perceptions of role demands and caregiving. The aim of this study was to identify direct and indirect predictors of burden among Bedouin caregivers of family members with terminal cancer in Israel.Methods: A total of 101 Bedouin family caregivers of terminal cancer patients participated in this study. Participants were recruited from the oncology department of the largest medical center in southern Israel. The questionnaire battery included the Arabic version of the Zarit Burden Interview and other reliable measures validated for cancer caregiving. We performed path analyses on data allowing us to identify hypothesized, and un-hypothesized predictors of burden in this understudied population.Results: Most caregivers were adult children, followed by spouses, siblings and other family members. In our model, caregiver burden was directly predicted by depressive symptoms and (absence of) social support. Burden was indirectly predicted by quality of life (via depressive symptoms), optimism (via social support), emotional exhaustion (via quality of life and depressive symptoms) and mortality communication (via emotional exhaustion, quality of life and depressive symptoms).Conclusion: Social support and depression are the most important factors among all studied measures. Culturally-tailored intervention programs are required to foster community care and mitigate burden for Bedouin and other ethnic minority groups in Israel.

Caregiver in Alzheimer's disease, pharmacist, and pharmacy technician attitudes and knowledge about caregiver burden screening in community pharmacies

OBJECTIVES

To explore caregiver, pharmacist and pharmacy technician attitudes toward burden screening in community pharmacies and assess caregiver burden in community pharmacies.

METHODS

Descriptive cross-sectional study conducted in 10 community pharmacies in France. Pharmacists, pharmacy technicians and caregivers of patients with Alzheimer's disease were included in this study. Two self-reported questionnaires were used to explore attitudes of participants toward the burden screening in community pharmacy and to assess the caregiver burden in community pharmacy. The short version of the Zarit Burden Interview (range 0-7) was used for the burden screening.

RESULTS

Fifty-two pharmacists and pharmacy technicians, and 20 caregivers (61.8±13.7years) participated in this study. Seventy percent of caregivers and 96% of pharmacists/pharmacy technicians stated that caregiver burden screening should be conducted in community pharmacies. 65% of caregivers reported their caregiver status to their community pharmacist. Eighty-two percent of pharmacist/pharmacy technicians thought they had to inform the caregiver's general practitioners (GP) about the detected burden level. Of the 20 included caregivers, 18 had a perception of burden. The mean caregiver burden score detected in this exploratory study was 4.0±1.7, corresponding to a moderate to severe burden.

CONCLUSIONS

According to caregivers' opinion, community pharmacists and pharmacy technicians represent accessible health care professionals in primary care to quantify caregiver burden. The burden screening can be easily incorporated into clinical service offerings in community pharmacy practice. It provides a valuable opportunity to identify high-risk caregivers with the aim of referring them to their GP to prevent the caregiver's frailty.

Integrating Caregiver Support into Multiple Sclerosis Care

With loss of mobility in Multiple Sclerosis (MS) comes increase in caregiver assistance, burden, stress, and depression. This 6-month feasibility study used a pre-post design to test integration of a validated, behavioral, caregiving intervention into an ongoing MS clinic. Because the program focused on caregivers, there were no additional services provided to the persons living with MS other than usual medical care. Twenty-five MS caregivers received REACH VA (Resources for Enhancing All Caregivers’ Health in the VA), a six-session behavior-focused intervention during two to three months designed to increase caregiver skills in managing their own stress and burden and MS related issues and concerns, with a focus on mobility. Caregivers were assessed at baseline, three, and six months. Caregivers’ expectations of the program were to receive education on MS, caregiving and stress management skills, and support. The major benefits caregivers reported were understanding their loved one’s condition and how to better provide care. At six months, caregivers reported statistically and clinically significant improvements in depressive symptoms and bother with challenging MS behaviors. Persons with MS reported benefit for their caregivers and for themselves; 71% reported that their caregivers had helped them with mobility and function. Study results suggest that the addition of the brief REACH caregiver intervention into an MS clinic would benefit both caregivers and persons with MS. Although the intervention was six sessions over three months, benefit persisted at six months, suggesting durability of effects. This trial is registered with ClinicalTrials.gov NCT02835677.

Characteristics of Young-Onset and Late-Onset Dementia Patients at a Remote Memory Clinic

Background:

Young-onset dementia (YOD) is defined as the onset of dementia symptoms before the age of 65 years and accounts for 2–8% of dementia. YOD patients and their caregivers face unique challenges in diagnosis and management. We aimed to compare the characteristics of rural YOD and late-onset dementia (LOD) patients at a rural and remote memory clinic in Western Canada.

Methods:

A total of 333 consecutive patients (YOD = 61, LOD = 272) at a rural and remote memory clinic between March 2004 and July 2016 were included in this study. Each patient had neuropsychological assessment. Health, mood, function, behaviour and social factors were also measured. Both groups were compared using χ2 tests and independent sample tests.

Results:

YOD patients were more likely to be married, employed, current smokers and highly educated. They reported fewer cognitive symptoms, but had more depressive symptoms. YOD patients were less likely to live alone and use homecare services. YOD caregivers were also more likely to be a spouse and had higher levels of distress than LOD caregivers. Both YOD and LOD patient groups were equally likely to have a driver’s licence.

Conclusions:

Our findings indicate YOD and LOD patients have distinct characteristics and services must be modified to better meet YOD patient needs. In particular, the use of homecare services and caregiver support may alleviate the higher levels of distress found in YOD patients and their caregivers. Additional research should be directed to addressing YOD patient depression, caregiver distress and barriers to services.

Evaluating case management as a complex intervention: Lessons for the future

The methodological challenges to effectiveness evaluation of complex interventions has been widely discussed. Bottom-up case management for frail older person was implemented in Belgium, and indeed, it was evaluated as a complex intervention. This paper presents the methodological approach we developed to respond to four main methodological challenges regarding the evaluation of case management: (1) the standardization of the interventions, (2) stratification of the frail older population that was used to test various modalities of case management with different risks groups, (3) the building of a control group, and (4) the use of multiple outcomes in evaluating case management. To address these challenges, we developed a mixed-methods approach that (1) used multiple embedded case studies to classify case management types according to their characteristics and implementation conditions; and (2) compared subgroups of beneficiaries with specific needs (defined by Principal Component Analysis prior to cluster analysis) and a control group receiving 'usual care', to evaluate the effectiveness of case management. The beneficiaries' subgroups were matched using propensity scores and compared using generalized pairwise comparison and the hurdle model with the control group. Our results suggest that the impact of case management on patient health and the services used varies according to specific needs and categories of case management. However, these equivocal results question our methodological approach. We suggest to reconsider the evaluation approach by moving away from a viewing case management as an intervention. Rather, it should be considered as a process of interconnected actions taking place within a complex system.

How to address the needs of non-responders to REACH VA: a qualitative analysis

Objective: This study used qualitative methods to understand how to further alleviate symptoms of depression and caregiver burden and address the needs of non-responders following a course of Resources for Enhancing Alzheimer's Caregiver Health in VA (REACH VA). Methods: Semi-structured interviews with caregivers and interventionists post-treatment were coded for themes related to ways to address the needs of non-responder caregivers. Results: The following suggestions recurred among non-responder caregivers and interventionists: (1) tailor skills and psychoeducation material to caregiver's needs; (2) provide greater overall support within the realm of caregiving; (3) explore and process caregiver's emotions around caregiving experience and grief; (4) address interpersonal difficulties and barriers to asking for help; (5) spend more time practicing skills to aid in implementing them at home. Conclusions: For many non-responders, a longer-term treatment targeting caregivers' emotional processing, interpersonal skills, social connection, acquisition and implementation of skills is indicated.

Protocol for a Cluster Randomized Trial Comparing Team-Based to Clinician-Focused Implementation of Advance Care Planning in Primary Care

Introduction: For many patients, primary care is an appropriate setting for advance care planning (ACP). ACP focuses on what matters most to patients and ensuring health care supports patient-defined goals. ACP may involve interactions between a clinician and a patient, but for seriously ill patients ACP could be managed by a team. Methods: We are conducting a cluster randomized trial comparing team-based to clinician-focused ACP using the Serious Illness Care Program (SICP) in 42 practices recruited from 7 practice-based research networks (PBRNs). Practices were randomized to one of the two models. Patients are referred to the study after engaging in ACP in primary care. Our target enrollment is 1260 subjects. Patient data are collected at enrollment, six months and one year. Primary outcomes are patient-reported goal-concordant care and days at home. Secondary outcomes include additional patient measures, clinician/team experience, and practice-level measures of SICP implementation. Study Implementation: This trial was designed and is conducted by the Meta-network Learning and Research Center (Meta-LARC), a consortium of PBRNs focused on integrating engagement with patients, families, and other stakeholders into primary care research and practice. The trial pairs a comparative effectiveness study with implementation of a new program and is designed to balance fidelity to the assigned model with flexibility to allow each practice to adapt implementation to their environment and priorities. Our dissemination will report the results of comparing the two models and the implementation experience of the practices to create guidance for the spread of ACP in primary care.

Measures used to assess impact of providing care among informal caregivers of persons with stroke, spinal cord injury, or amputation: a systematic review

PURPOSE

(1) To identify measures used to evaluate the impact of caregiving among caregivers of persons with stroke, spinal cord injury, and amputation; and (2) to systematically evaluate their clinimetric properties reported in validation studies.

MATERIALS AND METHODS

Two separate systematic reviews (Embase, PsycINFO, CINAHL, Pubmed/Medline) were conducted. COSMIN guidelines were used to assess clinimetric properties and methodological quality of studies.

RESULTS

(1) 154 studies published between 2008 and May 2019 were included, in which 48 measures were used, mostly describing negative impact. Thirty measures were used only once and not further described. (2) In general, structural validity, internal consistency, and hypothesis testing were often investigated. Reliability, cross-cultural and criterion validity to a lesser extent, and scale development and content validity were rarely described. Tests of measurement error and responsiveness were exceptional. Most supporting evidence was found for the Zarit Burden Interview Short Form, Caregiver Burden Scale and Positive Aspects of Caregiving Questionnaire.

CONCLUSIONS

There is a wide variety of impact of caregiving measures. The present study provided a detailed overview of what is known about clinimetric characteristics of 18 different measures repeatedly used in research. The overview provides clinicians a guidance of appropriate measure selection.

Evaluation of bottom-up interventions targeting community-dwelling frail older people in Belgium: methodological challenges and lessons for future comparative effectiveness studies

Background

Optimizing the organization of care for community-dwelling frail older people is an important issue in many Western countries. In Belgium, a series of complex, innovative, bottom-up interventions was recently designed and implemented to help frail older people live at home longer. As the effectiveness of these interventions may vary between different population groups according to their long-term care needs, they must be evaluated by comparison with a control group that has similar needs.

Methods

The goal was to identify target groups for these interventions and to establish control groups with similar needs and to explore, per group, the extent to which the utilization of long-term care is matched to needs. We merged two databases: a clinical prospective database and the routine administrative database for healthcare reimbursements. Through Principal Component Analysis followed by Clustering, the intervention group was first stratified into disability profiles. Per profile, comparable control groups for clinical variables were established, based on propensity scores. Using chi-squared tests and logistic regression analysis, long-term care utilization at baseline was then compared per profile and group studied.

Results

Stratification highlighted five disability profiles: people with low-level limitations; people with limitations in instrumental activities of daily life and low-level of cognitive impairment; people with functional limitations; people with functional and cognitive impairments; and people with functional, cognitive, and behavioral problems. These profiles made it possible to identify long-term care needs. For instance, at baseline, those who needed more assistance with hygiene tasks also received more personal nursing care (P < 0.05). However, there were some important discrepancies between the need for long-term care and its utilization: while 21% of patients who were totally dependent for hygiene tasks received no personal nursing care, personal nursing care was received by 33% of patients who could perform hygiene tasks.

Conclusions

The disability profiles provide information on long-term care needs but not on the extent to which those needs are met. To assess the effectiveness of interventions, controls at baseline should have similar disability profiles and comparable long-term care utilization. To allow for large comparative effectiveness studies, these dimensions should ideally be available in routine databases.

The optimal short version of the Zarit Burden Interview for dementia caregivers: diagnostic utility and externally validated cutoffs

OBJECTIVES

Using a sample of dementia caregivers, we compared the diagnostic utility of the various short versions of the Zarit Burden Interview (ZBI) with the original scale to identify the most optimal one. Next, we established externally validated cutoffs for the various ZBI versions using probable depression cases as a reference standard.

METHODS

Caregivers (N = 394; 236 males; Age_mean = 56 years) were administered the ZBI and a self-report depression measure. Participants who exceeded the cutoff for the latter were identified as probable depression cases. For each of the ZBI versions, a receiver operating characteristic (ROC) curve was plotted against probable depression cases. The area under these ROC curves between the short versions and the original were then compared using a non-parametric approach.

RESULTS

Compared to the original ZBI, the AUROC were similar for the 6-item, 7-item, and two 12-item versions, but significantly worse for the other short variants. The sensitivity and specificity of the cutoffs for all ZBI versions ranged from 77.3% to 85.2% and 60.1% to 79.8%, respectively.

CONCLUSIONS

The original ZBI had good utility in identifying probable depression in caregivers, while the 6-item variant can be a useful alternative when short versions are preferred.

Closer: A videoconference intervention for distance caregivers of cancer patients

Distance caregivers (DCGs) represent a growing demographic. The emotional burden of caregiving for a family member with cancer is amplified by the logistical challenges of providing support from afar. DCGs feel higher levels of distress, anxiety, and depression compared with local caregivers. Videoconference technology may alleviate both the emotional and practical burdens faced by DCGs. This is an ongoing randomized controlled trial in 32 outpatient ambulatory clinics at a large, urban, comprehensive cancer center. To date, 332 patient-DCG dyads have been enrolled. DCGs must have internet access and have been identified by the patient as a source of support. The intervention period is 4 months. DCGs are randomized to one of three arms: DCGs in Arm 1 receive four coaching sessions with an advanced practice nurse or social worker and four videoconference appointments during the oncologist-patient office visit. DCGs in Arm 2 participate in four videoconference appointments with the oncologist and patient, and Arm 3 is the control group, which receives access to information through a website. Primary outcome variables are DCG distress, anxiety, depression, burden, self-efficacy, and emotional support. These data are collected electronically at baseline, 4 months, and 6 months. Patient distress, anxiety, and depression are also assessed at these same intervals using brief in-person interviews. The change in each of the DCG outcomes over time will be examined by a repeated measures analysis of covariance.

Comprehensive Family Caregiver Support and Caregiver Well-Being: Preliminary Evidence From a Pre-post-survey Study With a Non-equivalent Control Group

Introduction: In May 2010, the Caregivers and Veterans Omnibus Health Services Act of 2010, was signed into law in the United States, establishing the Program of Comprehensive Assistance for Family Caregivers (PCAFC) provided through the VA Caregiver Support Program (CSP). Prior to this program, over half of family caregivers reported being untrained for the tasks they needed to provide. The training through PCAFC represents the largest effort to train family caregivers in the U.S., and the features of the program, specifically a monthly stipend to caregivers and access to a Caregiver Support Coordinator at each VA medical center nationally, make it the most comprehensive caregiver support program ever enacted in the U.S. Methods: The purpose of this study is to examine the association between PCAFC participation and caregiver well-being following enrollment, comparing participating PCAFC caregivers to caregivers who applied to but were not approved for PCAFC participation (non-participants). Well-being is defined using three diverse but related outcomes: depressive symptoms, perceived financial strain, and perceived quality of the Veteran's health care. Additional well-being measures also examined include the Zarit Burden Inventory and positive aspects of caregiving. Results: The survey sample comprised of 92 caregivers approved for PCAFC and 66 caregivers not approved. The mean age of responding caregivers was 45; over 90% of caregivers were female; and over 80% of caregivers were married in both groups. We find promising trends in well-being associated with PCAFC participation. First, the perception of financial strain declined among participants compared to non-participants. Second, while depressive symptoms did not improve for the PCAFC caregivers, depressive symptoms increased among non-participants. Third, perceived quality of the Veteran's VA healthcare was no different between participants and non-participants. However, the 158 returned surveys reflect only a 5% response rate; hence this evidence is preliminary. Conclusion: Despite cautioning that results be interpreted as preliminary, this study provides unique descriptive information about young caregivers of U.S. post-9/11 Veterans, and offers a first step in filling the evidence gap about how comprehensive caregiver support in the U.S. may affect caregiver well-being. These preliminary findings should be explored and validated in a larger sample.

Caregiver burden and quality of life 2 years after attendance at a memory clinic

OBJECTIVES

We aimed to describe (1) the burden and health-related quality of life (HRQL) of informal caregivers of new patients attending a memory assessment service (MAS), (2) changes in these outcomes over 2 years, and (3) satisfaction with services.

METHODS

Informal caregivers of patients attending one of 73 MASs throughout England completed questionnaires at the patient's first appointment, and 6 and 12 months later. Participants from 30 of these MASs were also followed up at 24 months. Questionnaires covered caregivers' sociodemographic characteristics, Zarit Burden Interview, EQ-5D-3L, and satisfaction with services. We used multivariable linear regression to assess relationships between burden, HRQL, and caregiver and patient characteristics.

RESULTS

Of 1020 caregivers at baseline, 569 were followed up at 6 months, 452 at 12 months, and 187 at 24 months. There was a small increase in caregiver burden over 2 years (effect size 0.30 SD). These changes were not associated with most caregiver or patient characteristics, except socio-economic deprivation, which was associated with larger increases in burden at 2 years. Caregivers' HRQL was weakly associated with burden and showed a small reduction over time (0.2 SD). Most caregivers were satisfied with services, but caregivers who were not satisfied with the services they received reported greater increases in burden.

CONCLUSIONS

Increases in caregiver burden and reductions in HRQL appear to be small over the first 2 years after attending a MAS. However, the longer term impact on caregivers and those they care for needs investigating, as do strategies to reduce their burden.

Psychometric Properties of a Modified Version of the Caregiver Reaction Assessment Scale Measuring Caregiving and Post-Caregiving Reactions of Caregivers of Cancer Patients

Most care received by cancer patients is provided in the community by informal or unpaid caregivers. The unrelenting care demands can lead to physical, emotional, social, and financial reactions; furthermore, studies indicate that the effects of caregiving may endure after the patient's death. A need therefore exists for instruments measuring both caregiving and post-caregiving reactions. Among available instruments, the Caregiver Reaction Assessment (CRA) is a multidimensional, 5-factor measure designed to assess the negative and positive aspects of caregiving. The current study examined the psychometric properties and factor structure of responses to a modified Hebrew version of the CRA aimed at measuring caregiving and post-care-giving reactions. Although the scale was modified, it was assumed that, similar to the original CRA, a 5-factor structure would be supported by means of confirmatory factor analysis. A total of 236 bereaved primary caregivers of cancer patients from central and southern regions of Israel were recruited over a period of 18 months. As hypothesized, results provide support for a 5-factor structure of responses to this modified version of the CRA. The concurrent validity of responses to the scale was also supported. Replication of the findings with randomly derived and larger sample sizes is needed.

Perceptions of a psychoeducation program for caregivers of persons with dementia at end of life: a qualitative study

OBJECTIVES

Caregivers (CG) of persons with dementia have described positive and challenging experiences related to caring for a person with a neurological disease. This study explored perceived benefits and challenges of a unique psychoeducation program provided at end of life (EOL) jointly attended by current and bereaved CGs of persons with dementia, residing in a hospital Specialized Care Unit.

METHOD

Semi-structured interviews were held with sixteen participants and analyzed with content analysis.

RESULTS

Program benefits were perceived by CGs such as: (i) enhanced emotional well-being, (ii) increased feelings of preparedness for EOL, and (iii) personal growth into role models. Within the organization the program was perceived as promoting relationship-centered care and increasing resources. Challenges such as diverse CG preferences, day-time scheduling and limited involvement of unit staff were perceived as barriers.

CONCLUSIONS

This program fills a gap in care for CGs at the critical stage of EOL with continuity into bereavement. Implications for practice include: increasing engagement of unit staff for involvement and tailoring of the program, and translation of the program into alternative settings like long-term care. Policies outlining the support needs and resources for CGs through EOL within and outside the hospital are necessary to ensure access and continuity of care.

Factors emerging from the "Zarit Burden Interview" and predictive variables in a UK sample of caregivers for people with dementia

ABSTRACTBackground:Caring for persons with dementia (PWD) can create "caregiver burden," which is associated with negative outcomes for caregivers and PWD. The ZBI (Zarit Burden Interview) is a widely used unitary measure of caregiver burden. However, recent research has found caregiver burden to be multi-dimensional. The purpose of this study was to explore the factor structure of the ZBI within a sample of UK caregivers. A secondary aim was to identify variables that predicted burden dimensions found.

METHODS

A total of 110 unpaid community caregivers of PWD completed the ZBI. They also completed the EACQ (Experiential Avoidance in Caregiving Questionnaire), DEX (Dysexecutive Questionnaire), PACS (Positive Aspects of Caregiving Scale), and a demographic questionnaire. ZBI data were analyzed via exploratory factor analysis (principal axis factoring). Relationships between burden factors and other variables were studied using Pearson correlations and multiple regression.

RESULTS

Analysis identified three burden factors, namely direct impact of caregiving, uncertainty around the future, and frustration/embarrassment. A direct impact of caregiving and frustration/embarrassment has been found previously. Uncertainty over the future is a new factor, which was predicted by adult-child caregiver role, highlighting that spouses and adult children are likely to have different burden experiences. Additionally, uncertainty over the future and frustration/embarrassment were inversely predicted by PACS, suggesting that being mindful of positive aspects of caregiving may function as a protective factor for burden.

CONCLUSIONS

This study found caregiver burden to be multi-dimensional and uncovered a novel factor in uncertainty over the future, which warrants further exploration. Burden factors were associated with a range of modifiable variables that could be targeted within health and social care interventions to improve outcomes for caregivers and PWD.

Identity, relationship quality, and subjective burden in caregivers of persons with dementia

The aim of the current study was to examine the associations between informal caregivers’ perception of identity change in their care-partner, the quality of the caregiver/care-recipient relationship, and caregiver burden in a sample of 56 informal caregivers of persons with dementia. Most (96.4%) of the caregivers of persons who received a dementia diagnosis reported a perceived change in the identity of their care-partner. Caregivers’ perception of relationship satisfaction was measured with the Burns Relationship Satisfaction Scale for premorbid relationship and current relationship quality, and caregiver burden was measured with the Zarit Burden scale. After controlling for variance due to dementia severity, premorbid relationship satisfaction, and current relationship satisfaction, caregivers’ perceived change in the identity of the person with dementia accounted for significant variance in caregiver burden. Using a mediational model, we found support for a direct effect between perceived change in identity and caregiver burden, but we also found support for an indirect effect of relationship quality on the relation between perceived identity change and caregiver burden. The demonstrated model provides an empirically supported theoretical framework for guiding potential research and development of future interventions, which we suggest should emphasize dyads.

Gender effects on components of burden and depression among dementia caregivers

OBJECTIVE

Previous literature has examined burden and depression predominately as unitary constructs in relation to dementia caregiving. No studies thus far have examined gender differences in the specific components of burden and depression in dementia caregivers. The current study examined whether empirically validated dimensions of caregiver burden differed by gender for dementia caregivers.

METHODS

The sample consisted of 211 dementia caregivers enrolled in a longitudinal intervention study. Only baseline functioning was evaluated in this study. Levels of burden were assessed using the Zarit Burden Interview (ZBI), and levels of depression were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D).

RESULTS

Factor analysis revealed three facets of burden: impact of caregiving on the caregivers' lives, guilt, and frustration/embarrassment, and four facets of depression: depressed affect, somatic activity, positive affect, and interpersonal feelings. Overall burden (p < .001) and impact of caregiving on the caregivers' life (p < .001) were significantly higher in females. Overall levels of depression (p = .018), somatic and retarded activity (p = .018), depressed affect (p = .005), and positive affect (p = .012) were significantly higher in females.

CONCLUSIONS

Findings suggest that distressed male and female dementia caregivers experience caregiving differently. Results from this study could be used to identify gender-specific interventions related to subtypes of burden and depression to optimize quality of life for caregivers.

Variance in caregiver burden predicted by patient behaviors versus neuropsychological profile

Informal caregivers provide the majority of care to persons with dementia; efforts to support caregivers' well-being are increasingly important in the context of limited formal healthcare supports. Informal caregiving is commonly associated with caregiver burden and burden may depend upon patient characteristics including neuropsychological profile, dementia severity, and dementia etiology. This study investigated predictors of caregiver burden in a sample of 213 Memory Clinic patients diagnosed with dementia and whose caregivers provided collateral information. Caregiver burden was similar irrespective of dementia etiology. Beyond the expected predictive value of dementia severity on caregiver burden, patient behavioral symptoms, functional dependence, and caregiver psychological distress were predictive of caregiver burden. In contrast, care-recipient neuropsychological performance did not predict burden. These findings suggest that beyond severity of dementia, specific behavioral disturbances predict caregiver burden which may have implications for programming and intervention aimed at supporting and sustaining caregivers in their role.

Factors Underpinning Caregiver Burden in Frontotemporal Dementia Differ in Spouses and their Children

The objectives of this observational study were to (1) compare spousal and child caregiver burden; (2) compare co-resident and live-out child caregiver burden; and (3) investigate factors influencing spousal and child caregiver burden. Data was collected from 90 caregivers of people with frontotemporal degeneration (FTD) recruited from the Frontotemporal Dementia Research Group (Frontier) at Neuroscience Research, Australia. Of this caregiver group, 43 were spousal caregivers and 47 were child caregivers. Caregiver burden and emotional state were evaluated using the short Zarit Burden Interview and the short version of the Depression, Anxiety and Stress Scale-21. The Social Network Index was applied to ascertain the social network of the caregiver, while the Intimate Bond Measure was used to evaluate the current quality of the relationship between the caregiver and the person with dementia. The Frontotemporal Dementia Rating Scale was used to assess severity of dementia. Spousal and child caregivers experienced similar levels of burden, depression, anxiety, and stress, regardless of disease severity. Co-resident child caregivers had smaller social networks and greater burden than live-out caregivers. Dementia severity was key in spousal caregiver burden, whereas caregiver depression was most important in child caregiver burden. Child and spousal caregivers of individuals with FTD share similar levels of burden, influenced by different factors. Future interventions need to account for these differences.

Telehealth Rehabilitation for Cognitive Impairment: Randomized Controlled Feasibility Trial

Background

Nonpharmacological interventions are needed to support the function of older adults struggling with subjective cognitive impairment (SCI), mild cognitive impairment (MCI), and dementia due to Alzheimer disease (AD). Telerehabilitation aims to provide rehabilitation at a distance, but cognitive rehabilitation by videoconferencing has not been explored.

Objective

The objective of this study was to compare goal-oriented cognitive rehabilitation delivered in-person with videoconferencing to determine whether telehealth cognitive rehabilitation appears feasible.

Methods

Random assignment to in-person or telehealth videoconferencing cognitive rehabilitation with a combined between-subjects, multiple baseline single-case experimental design, cognitive rehabilitation was delivered by a therapist to 6 participants with SCI (n=4), MCI (n=1), or dementia due to AD (n=1).

Results

Two of the 6 participants randomly assigned to the telehealth condition withdrew before beginning the intervention. For those who participated in the intervention, 6 out of 6 goals measured with the Canadian Occupational Performance Measure improved for those in the in-person group, and 7 out of 9 goals improved for those in the telehealth group.

Conclusions

Delivery of cognitive rehabilitation by telehealth appeared feasible but required modifications such as greater reliance on caregivers and clients for manipulating materials.

Treatment of Advanced Parkinson Disease and Related Disorders

PURPOSE OF REVIEW

Parkinson disease often spans decades of a patient's lifetime. Over time, nonmotor symptoms predominate and may limit dopaminergic therapy. Neurologists continue to play a vital role in treatment. In addition to balancing neurobehavioral complications of Parkinson disease with motor benefit, addressing nonmotor symptoms common in the advanced stage may improve quality of life and reduce symptom burden. Symptoms such as dysphagia, constipation, urinary dysfunction, orthostatic hypotension, and pain respond to nonpharmacologic and pharmacologic therapies.

RECENT FINDINGS

Evidence for treatment of many nonmotor symptoms is weak or lacking. The evidence for treatment of the atypical parkinsonian syndromes (progressive supranuclear palsy, multiple system atrophy, and corticobasal degeneration) in advanced stages is even more scant.

SUMMARY

Engaging palliative care physicians in the joint care of patients can provide patients with access to expertise in end-of-life issues. Neurologic illnesses have specific hospice criteria to guide clinicians for referrals. Evidence supports that assisting patients with advance directives can result in improved satisfaction with care and improved quality of life in the last weeks of life. Neurologists can remain engaged in their patients' care throughout the course of illness.

Development and Initial Validation of the Caregiver Perceptions About Communication With Clinical Team Members (CAPACITY) Measure

Despite the important role that family caregivers play managing the care of persons with complex health needs, little is known about how caregivers perceive themselves to be recognized and valued by health care professionals. Our objective was to develop and validate a novel measure, the CAregiver Perceptions About CommunIcation with Clinical Team members (CAPACITY) instrument. Questions focus on perceived quality of communication with the health care team and the extent to which caregivers believe that the health care team considers their capacity and preferences in decision making. A confirmatory factor analysis supported a two-factor solution addressing communication and capacity. Internal consistency reliability was .90 for the communication domain and .93 for the capacity domain. Correlations between these two subscales and individual difference measures provided evidence of convergent and discriminant validity. The CAPACITY instrument may be a useful performance measure that quantifies the extent to which caregivers' experience person- and family-centered health care.

Factor analyses of the Chinese Zarit Burden Interview among caregivers of patients with schizophrenia in a rural Chinese community

OBJECTIVE

This study aimed to evaluate the factor structure of the Chinese version of the 22-item Zarit Burden Interview (ZBI) among family caregivers of patients with schizophrenia in China.

METHODS

Using one-stage cluster-sampling design, 324 primary caregivers of patients with schizophrenia in Ningxiang County, Hunan Province, China, completed the Zarit Burden Interview face-to-face. Confirmatory factor analysis (CFA) was first performed based on existing models to check model fit. Owing to an unsatisfactory result of CFA, exploratory factor analysis (EFA) was then conducted to explore a new factor structure, and a subsequent CFA was run to examine its model fit.

RESULTS

The CFA results showed that none of the existing models fit the data reasonably well. The EFA results suggested five dimensions: negative emotion (10 items), interpersonal relationship (4 items), time demand (3 items), patient's dependence (2 items) and self-accusation and guilt (2 items). The following CFA confirmed the five-factor solution in this study, and the goodness-of-fit for this model fell within the acceptable range. The overall internal consistency (Cronbach's alpha) was 0.88, and the internal consistency coefficients of individual dimensions were 0.68 to 0.84.

CONCLUSION

This study supported a 22-item ZBI scale, with a five-factor structure when applied to Chinese caregivers of patients with schizophrenia.

Sleep in family caregivers of ICU survivors for two months post-ICU discharge

OBJECTIVE

To describe changes in sleep quality in family caregivers of ICU survivors from the patients' ICU admission until two months post-ICU discharge.

DESIGN

Descriptive repeated measure design.

SETTING

Academic hospital medical ICU.

MAIN OUTCOME MEASURES

Subjective sleep quality (Pittsburgh Sleep Quality Index [PSQI]) and objective sleep/wake variables (SenseWear Armband™) were measured in family caregivers at patients' ICU admission, within two weeks post-ICU discharge and two months post-ICU discharge.

RESULTS

In 28 family caregivers of ICU survivors, most caregivers reported poor sleep quality (i.e. PSQI >5) across the three time points (64.3% during patients' ICU admission, 53.6% at each post-ICU time point). Worse trends in sleep quality and objective sleep/wake pattern were observed in caregivers who were employed, and a non-spouse. There were trends of worsening sleep quality in caregivers of patients unable to return home within two months post-ICU discharge compared to patients able to return home.

CONCLUSIONS

Poor sleep quality was highly prevalent and persisted in family caregivers of ICU survivors for two months post-ICU discharge. Our data support the need for a larger longitudinal study to examine risk factors associated with sleep quality in family caregivers of ICU survivors to develop targeted interventions.

Strength and stress: Positive and negative impacts on caregivers for older adults in Thailand

Aim

To understand the experiences of caregivers with older people living in Thailand, particularly as related to quality of life and stress management.

Method

In‐depth interviews with 17 family caregivers were conducted and then data were thematically analysed.

Results

Carers experience not only negative impacts but also positive impacts from caregiving. Negative impacts include emotional stress, financial struggles and worry due to lack of knowledge. Positive impacts include affection from care recipients, good relationships with caregivers before needing care themselves and encouragement from the wider community. Opportunities to show gratitude, build karma (from good deeds) and ideas shaped largely by Buddhist teachings result in positive experiences. Negotiating between the extremes of bliss and suffering and understanding suffering as a part of life may help carers manage their stress.

Conclusions

Temples and centres for older people could be engaged to develop caregiving programs.
