Psychometric properties of the Hebrew version of the Zarit Caregiver Burden Scale short version

A scale development study: Primary Caregiver Burden Scale Individuals Receiving Hemodialysis Treatment

INTRODUCTION

As hemodialysis is a long-term treatment method requiring significant self-management skills, it affects both the patient and the caregiver in many ways. It is inevitable that changes in the burden perceived by the caregiver over time will not affect the patient's health care outcomes. The aim of this study was to develop an up-to-date scale by examining the psychometric properties of items created specifically for the care burden perceived by individuals who provide care for patients receiving hemodialysis treatment.

METHODS

This study is a methodological study with the use of the COSMIN Checklist. The sample of the study included 404 individuals who were the primary caregivers of patients receiving hemodialysis treatment. Data were collected using descriptive characteristics form and the draft form of the Primary Caregiver Burden Scale Individuals Receiving Hemodialysis Treatment. Exploratory and confirmatory factor analysis and predictive validity were used to evaluate validity. The Cronbach's alpha reliability coefficient, item analysis, and test-retest method were employed to evaluate reliability.

RESULTS

According to exploratory factor analysis, a scale structure with four subdimensions was determined, and goodness of fit was achieved using confirmatory factor analysis. The Cronbach's alpha coefficient of the final form of the scale consisting of 34 items was found to be 0.95 for the total scale, 0.93 for the self-management support subscale, 0.91 for the psychological support subscale, 0.91 for the caregiver symptom subscale, and 0.93 for the caregiver individual coping subscale.

CONCLUSION

The Primary Caregiver Burden Scale Individuals Receiving Hemodialysis Treatment, which was found to meet the validity and reliability criteria, has a four-point Likert-type scoring structure, 34 items, and four subdimensions. It is thought that the scale can make significant contributions to the international literature if its validity and reliability are established with nursing practices and research.

Direct and Indirect Predictors of Burden in Arab-Bedouin and Jewish-Israeli Mothers Caring for a Child with Epilepsy

OBJECTIVE

Caring for a child with epilepsy poses various psychological, physical and medical challenges; these can lead to caregiver burden. The aim of this study was to identify predictors of burden with mothers caring for a child with epilepsy. Our analyses included sociodemographic (e.g., ethnicity), mental health (e.g., symptoms of anxiety, depression) and physiological factors (e.g., extent of pharmacotherapy).

METHODS

A total of 168 mothers caring for a child with epilepsy were recruited while attending the Pediatric Neurology Clinic at Soroka Medical Center, Be'er Sheva, Israel. This cross-sectional sample included 130 Jewish-Israeli and 38 Arab-Bedouin mothers who completed parallel questionnaire batteries that included the Zarit Burden Interview and other scales translated and validated in Hebrew and Arabic. We computed path analyses to identify both direct and indirect predictors of caregiver burden.

RESULTS

Burden was directly predicted by emotional exhaustion, symptoms of anxiety and (Bedouin) ethnicity. Indirect effects on burden included illness severity (via emotional exhaustion), ethnicity and emotional exhaustion (both via anxiety). That is, both ethnicity and emotional exhaustion directly and indirectly predicted caregiver burden via greater anxiety. Illness severity indirectly predicted symptoms of depression, anxiety and caregiver burden. We found that 55% of epilepsy care burden was predicted by this path model.

CONCLUSIONS

Bedouin mothers reported greater illness severity, symptoms of depression, anxiety and caregiver burden. Differences between groups in epilepsy severity suggest that less severe cases in the Bedouin community do not come to clinical attention (e.g., are concealed due to stigma). These findings underscore the need for health promotion strategies and interventions for caregivers tailored to account for ethnic and cultural differences.

Interventions that may increase control at the end of life in persons with dementia: the cross-cultural CONT-END acceptability study protocol and pilot-testing

BACKGROUND

Interventions such as advance care planning (ACP), technology, or access to euthanasia may increase the sense of control over the end of life. In people with advanced dementia, the loss of cognitive and physical function limits the ability to control care. To date, little is known about the acceptability of these interventions from the perspective of persons with dementia and others involved. This study will examine the cross-cultural acceptability, and factors associated with acceptability, of four end-of-life interventions in dementia which contain an element of striving for control. Also, we report on the development and pilot testing of animation video vignettes that explain the interventions in a standardized manner.

METHODS

Cross-sectional mixed-methods vignette study. We assess acceptability of two ACP approaches, technology use at the end of life and euthanasia in persons with dementia, their family caregivers and physicians in six countries (Netherlands, Japan, Israel, USA, Germany, Switzerland). We aim to include 80 participants per country, 50 physicians, 15 persons with dementia, and 15 family caregivers. After viewing each animation video, participants are interviewed about acceptability of the intervention. We will examine differences in acceptability between group and country and explore other potentially associated factors including variables indicating life view, personality, view on dementia and demographics. In the pilot study, participants commented on the understandability and clarity of the vignettes and instruments. Based on their feedback, the scripts of the animation videos were clarified, simplified and adapted to being less slanted in a specific direction.

DISCUSSION

In the pilot study, the persons with dementia, their family caregivers and other older adults found the adapted animation videos and instruments understandable, acceptable, feasible, and not burdensome. The CONT-END acceptability study will provide insight into cross-cultural acceptability of interventions in dementia care from the perspective of important stakeholders. This can help to better align interventions with preferences. The study will also result in a more fundamental understanding as to how and when having control at the end of life in dementia is perceived as beneficial or perhaps harmful.

TRIAL REGISTRATION

The CONT-END acceptability study was originally registered at the Netherlands Trial Register (NL7985) at 31 August, 2019, and can be found on the International Clinical Trials Registry Platform.

A Performance-Based Teleintervention for Adults in the Chronic Stage after Acquired Brain Injury: An Exploratory Pilot Randomized Controlled Crossover Study

This pilot study aimed to investigate the initial effect of a remotely delivered performance-based client-centered intervention on activity performance and participation among adults in the chronic phase after acquired brain injury (ABI). Sixteen participants living at home with little to no assistance in basic daily activities were allocated into intervention or waitlist control groups. Assessments were conducted at the baseline, after the 3-month intervention/wait period, and at a 3-month follow-up. The primary outcomes were activity performance using the Canadian Occupational Performance Measure (COPM) and the Performance Quality Rating Scale (PQRS) and participation using the Mayo-Portland Adaptability Inventory-4 (MPAI-4). The intervention included weekly videoconferencing sessions using the Cognitive Orientation to Daily Occupational Performance approach (tele-CO-OP). The participants identified five functional goals, of which three were directly addressed. Wilcoxon signed-ranks test results showed no significant improvements in the control group at the end of the 3-month wait period. Pooled data from both groups showed significant improvements in COPM scores for trained and untrained goals following the intervention. Significant improvements were also found in the PQRS and MPAI-4 scores. Improvements were partially maintained at follow-up. Our preliminary results suggest that tele-CO-OP may positively impact the lives of adults after ABI who are coping with long-term disability.

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.

Investigating psychometric properties of the Thai version of the Zarit Burden Interview using rasch model and confirmatory factor analysis

Objective

The Zarit Burden Interview (ZBI) has been widely used to assess caregiver burden. Few research papers have investigated the Thai version of the ZBI. The study aimed to examine the psychometric properties of the Thai version of both the full length (ZBI-22) and short versions (ZBI-12) using Rasch analysis and confirmatory factor analysis among a sample of Alzheimer’s disease caregivers.

Results

The ZBI-22 fitted the Rasch measurement model regarding unidimensionality but not for ZBI-12. Five items from ZBI-22, and 2 items from ZBI-12 were shown to be misfitting items. Half of ZBI items were shown to be disordered category or threshold, and were locally dependent. CFA revealed three-factor and four-factor fitted the data the best for ZBI-22 and ZBI-12, respectively. Reliability was good for both forms of the ZBI (α = 0.86–0.92). Significant correlations were found with caregiver’s perceived stress, anxiety/depression, pain and mobility but not with self-care and usual activity (p > 0.05), indicating convergent and discriminant validity. To conclude, the Thai version ZBI-22, but not ZBI-12, supported the reliability and unidimensional scale among Alzheimer’s disease caregivers. Some misfitting items of the ZBI undermined the unidimensionality of the scale, and need revision.

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.
