Caregiver burden among caregivers of children with autism spectrum disorder

Background

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with deficits in social communication and interaction, restricted and repetitive patterns of behaviour, interests and activities. Autism spectrum disorder is associated with multiple comorbidities. As a result, caregivers of children with ASD experience increased levels of burden and poor quality of life. However, there is a paucity of information on the burden.

Aim

The study aimed to describe the sociodemographic profiles and determine the extent of the burden experienced by caregivers of children and adolescents with ASD.

Setting

The Child, Adolescent and Family Unit (CAFU) outpatient services at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH).

Methods

A quantitative, descriptive, cross-sectional study was done. Two self-administered questionnaires were used: a sociodemographic questionnaire and the 12-item Zarit Burden Interview questionnaire.

Results

The questionnaires were completed by 77 caregivers, of which the majority were female (n = 56 or 72.3%), mothers to children with ASD (n = 49 or 64.3%) and identified as Christian (p < 0.001). Most had completed secondary school or had a tertiary education (p = 0.003) and were employed (p < 0.001). Among the caregivers, 41.6% experienced mild to moderate burden, 33.8% experienced high burden and only 24.9% reported no to mild burden.

Conclusion

Caregivers of children and adolescents with a diagnosis of ASD are mostly mothers and experience mild to moderate levels of caregiver burden, suggesting the need for improved screening and psychosocial support programmes.

Contribution

This study highlights the burden experienced by primary caregivers of children with ASD and is one of the few comprehensive studies on this issue within the context of South Africa.

New insights from a multi-ethnic Asian progressive supranuclear palsy cohort

BACKGROUND

Progressive supranuclear palsy (PSP) is a rare, disabling, neurodegenerative disease, with few studies done in Asian populations.

METHODS

We prospectively characterized the clinical features and disease burden in a consecutively-recruited multi-ethnic Asian PSP cohort. Patients were extensively phenotyped using the Movement Disorder Society (MDS-PSP) clinical diagnostic criteria and the PSP-Clinical Deficits Scale (PSP-CDS). Caregiver burden was measured using the modified Zarit Burden Interview (ZBI). Investigations (neuroimaging and genetic tests) were reviewed.

RESULTS

There were 104 patients (64.4% male; 67.3% Chinese, 21.2% Indians, 9.6% Malays), consisting of 48.1% Richardson syndrome (PSP-RS), 37.5% parkinsonian phenotype (PSP-P), and 10.6% progressive gait freezing phenotype (PSP-PGF). Mean age at motor onset was 66.3 ± 7.7 years, with no significant differences between the PSP phenotypes. Interestingly, REM-sleep behaviour disorder (RBD) symptoms and visual hallucinations (considered rare in PSP) were reported in 23.5% and 22.8% of patients, respectively, and a family history of possible neurodegenerative or movement disorder in 20.4%. PSP-CDS scores were highest (worst) in PSP-RS; and correlated moderately with disease duration (r_s = 0.45, P < 0.001) and weakly with caregiver burden (r_s = 0.22, P = 0.029) in the overall cohort. Three of 48 (6.3%) patients who had whole-exome sequencing harboured pathogenic/likely pathogenic GBA variants.

CONCLUSIONS

Significant heterogeneity in clinical features and disease burden, and high rates of RBD symptoms, visual hallucinations, and familial involvement were observed in this relatively large cohort. Our findings highlight important considerations when assessing Asian patients, and provide further support for the notion of overlapping neurobiology between PSP and Lewy body disorders.

Development and Psychometric Validation of the 27 Item Zarit Caregiver Interview for Alzheimer's Disease (ZCI-AD-27)

BACKGROUND

Caring for an individual with Alzheimer's disease (AD) is an allencompassing challenge that affects daily life. Assessment of the care partner experience is needed to support the development and evaluation of successful interventions for people with AD and their care partners. We developed the 27-item Zarit Caregiver Interview for Alzheimer's Disease (ZCI-AD-27) to assess the impact of informal caregiving in the context of AD.

OBJECTIVE

We assessed the psychometric validity of the ZCI-AD-27 in a population of care partners for individuals with moderate AD, and established thresholds for meaningful score change.

METHODS

Secondary data were obtained from informal care partners of participants in a clinical trial (NCT01677754). Psychometric analyses were conducted to assess validity, reliability, and responsiveness of the ZCI-AD-27. Anchor-based and distribution-based methods were performed to determine clinically meaningful score change.

RESULTS

The ZCI-AD-27 had a 12-domain factor structure, including a second-order domain termed Humanistic impact that included four key domains (Physical, Emotional, Social, and Daily life) as confirmed by confirmatory factor analysis with the adequate fit. Internal consistency (Cronbach's alpha ranging from 0.66 to 0.93 for domains), convergent validity, and discriminant validity indicated the good performance of the ZCI-AD-27. Known-groups validity analyses showed a greater impact on care partners with increasing disease severity. Responsiveness results demonstrated that the ZCI-AD- 27 is sensitive to change over time and meaningful change analyses indicated a range of meaningful score changes in this population.

CONCLUSION

The ZCI-AD-27 is a comprehensive, psychometrically valid measure to assess the impact of caring for individuals with moderate AD.

Burden Among Caregivers of Pediatric Patients with Neurofibromatosis Type 1 (NF1) and Plexiform Neurofibroma (PN) in the United States: A Cross-Sectional Study

Introduction

Patients with neurofibromatosis type 1 (NF1) may develop plexiform neurofibromas (PNs) that can cause disfigurement, pain, and dysfunction, and may even be life-threatening. Studies have indicated NF1-PN can substantially impact the quality of life (QoL) of pediatric patients. However, research on caregiver burden is scarce.

Methods

Caregivers of pediatric patients ages 2–18 years with NF1-PN in the USA were recruited through the Children’s Tumor Foundation to participate in an online cross-sectional survey (December 2020–January 2021). Caregiver burden was measured using the Zarit Burden Interview (ZBI), and productivity loss from patientcare was measured using the Work Productivity and Activity Impairment questionnaire, adapted for caregiving (WPAI:CG).

Results

Ninety-five caregivers were recruited with a median age of 44.0 years. Most were female (88.4%), white/Caucasian (85.3%), and did not have NF1 or PN (86.3% and 89.5%, respectively). Commonly reported health conditions among caregivers include anxiety (48.4%) and depression (34.7%). On the ZBI (range 0–88; higher = greater burden), mean (SD) scores were 23.0 (13.8) and 12.7% of caregivers reported moderate–severe (scores 41–60) or severe burden (scores 61–88). Fifty-six caregivers were employed and working in the 7 days prior to completing the WPAI:CG. They reported missing an average of 6.9% of their working hours and an average reduction of 17.3% of on-the-job effectiveness, contributing to 22.3% loss in work productivity. Among all 95 caregivers, an average of 17.2% of regular daily activities were impaired.

Conclusions

The burden among caregivers of pediatric patients with NF1-PN is considerable and underscores an unmet need for better disease management.

Screening for Caregiver Burden in the Community: Validation of the European Portuguese Screening Version of the Zarit Burden Interview (ZBI-4)

Objectives: Brief screening instruments are useful in busy clinical practice to identify those requiring further assessment. This study aims to translate and validate a Portuguese version of the four-item Zarit Burden Interview (ZBI-4) to identify caregiver burden in a community-based sample in Northern Portugal.Methods: We collected data from 203 informal caregivers of community-dwellers aged ≥80 years. Internal consistency and factors were measured using Cronbach's alpha. Pearson's correlation was used to examine construct validity against negative and positive aspects of caregiving from the Caregiving Appraisal Scale. Discriminative ability was evaluated from the area under the receiver operating characteristic curve (AUC). Optimal cutoffs were calculated using Youden´s Index.Results: The internal consistency of the Portuguese version of the ZBI-4 was good (alpha = 0.71). Concurrent validity was acceptable, showing strong correlation with the negative (rho = 0.66) and medium correlation with positive (rho = -0.33) aspects of the Caregiving Appraisal Scale. Discriminative accuracy for caregiver burden was also good (AUC = 0.86). Youden's index produced an optimal cutoff of ≥7 points for burden.Conclusions: The Portuguese version of the ZBI-4 screen demonstrates good psychometric properties.Clinical implications: These results show the utility of the Portuguese version of ZBI-4 as a short screen for caregiver burden for use in the community to facilitate rapid screening for this important and complex stressor.

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.

Burden of caregiving for cardiovascular dysautonomia in Parkinson's disease

PURPOSE

We sought to estimate the impact of cardiovascular autonomic neuropathy (cAN) on informal caregivers of patients with Parkinson's disease (PD), defined as individuals providing regular care to a friend, partner, or family member with PD, and to evaluate the mutual relationship between caregiver burden and patient health-related quality of life (HRQoL).

METHODS

We enrolled 36 consecutive patients with PD and their informal caregivers. Patients underwent a detailed motor, autonomic, cognitive, and functional assessment. Caregivers were assessed using the Zarit Burden Interview (ZBI). Differences in caregiver burden, expressed by the ZBI score, and strength of association between caregiver burden, cAN, and HRQoL were assessed using analysis of covariance (ANCOVA), logistic regression, and linear regression analyses. Analyses were adjusted for patients' age, PD duration, and motor and cognitive disability, as well as caregivers' age.

RESULTS

Moderate-severe caregiver burden was reported in 41.7% of PDcAN⁺ versus 8.7% of PDcAN^- (p < 0.001). The ZBI score was increased in PDcAN⁺ versus PDcAN^- (31.5 ± 3.4 versus 15.2 ± 2.3; p < 0.001), with tenfold higher odds (p = 0.012) of moderate-severe caregiver burden in PDcAN⁺, even after adjusting for potential confounders. The ZBI score correlated with cAN severity (p = 0.005), global autonomic impairment (p = 0.012), and HRQoL impairment (p < 0.001).

CONCLUSION

These results highlight the significant impact of cAN on PD caregivers and the need for targeted interventions addressing this frequently overlooked and insufficiently treated source of nonmotor disability in PD.

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.

Assessment of the Psychological Burden Among Family Caregivers of People Living with Alzheimer's Disease Using the Zarit Burden Interview

BACKGROUND

In China, family caregivers play a major role in caring for people living with Alzheimer's disease (PLWAD), but little is known about the burden this creates.

OBJECTIVE

This study aimed to investigate the burden among family caregivers of PLWAD and the factors influenced it.

METHODS

Family caregivers of PLWAD were recruited from a hospital in China from January 2018 to July 2018. All data were collected online using the Chinese version of the Zarit Burden Interview (ZBI), and the participants' sociodemographic and caregiving details were obtained. T-tests and Kruskal-Wallis H (K) tests were used to compare ZBI scores between groups. Factors related to the caregiver psychological burden were analyzed using multiple linear regression analysis.

RESULTS

A total of 300 participants were assessed, of which 213 (71.00%) were female. More than half of the caregivers were the patient's daughter (51.0%, n = 153). The average ZBI score of the caregivers was 43.05 (13.42). The level of burden was influenced by age, the relationship of the caregiver to the patient, the severity of AD, the caregiver's retirement status, the income level of the caregiver, and the caring time. Regression analysis showed that retired caregivers were more likely to have higher levels of burden and that burden increased with AD severity.

CONCLUSION

Most family caregivers of PLWAD have a considerable caregiver psychological burden. The findings increase the understanding of factors that influence family caregiver burden, and pave the way for potential interventions, such as social support and caregiver empowerment, to reduce their burden.

Personal Determinants of Burden Among Indonesian Female Caregivers of Older Adults in Taiwan

INTRODUCTION

Families increasingly employ foreign domestic workers (FDWs) to care for older loved ones. Caregiver burden reflects FDWs' difficulty adapting to work demands. We test hypothesized associations between burden and six personal characteristics: children, marriage, education, Chinese proficiency, eldercare experience, and non-eldercare experience.

METHOD

In total, 299 Indonesian FDWs in Taiwan completed the Zarit Burden Interview. Exploratory factor analysis identified the dimensions of burden. Multiple and multinomial regressions related the variables to overall burden, burden dimensions, and burden severity.

RESULTS

Four dimensions were found: personal strain, role strain, dependency, and guilt. Children were negatively associated with burden, role strain, dependency, and guilt. Chinese proficiency was negatively associated with severity and guilt. Eldercare experience was positively associated with severity and personal strain. Marriage was non-monotonically related to severity.

CONCLUSION

Caregivers whose earnings benefit their children may be more likely to thrive in Taiwan. Language training may boost caregiver performance and host family satisfaction.

[Analysis of factors related to caregiver burden in carers of persons with cerebral palsy]

OBJECTIVE

Prevalence study describing the perception of burden among the caregivers of patients with cerebral palsy attending a neurological rehabilitation centre.

MATERIAL AND METHODS

This study was carried out in a neuro-rehabilitation centre in Cali, Colombia, with the participation of 117 caregivers of cerebral palsy patients. Information was gathered on caregiver burden, caregivers' sociodemographic characteristics and the patients' clinics between June and August 2017. Information on caregiver burden was collected with the Zarit Burden Interview. Burden was classified into 2 groups (light to moderate burden and moderate to severe burden) for the bivariate analysis.

RESULTS

Most caregivers experienced light to moderate burden (74%); an increase in the probability of burden among caregivers with moderate to severe burden was observed in the caregivers of women (OR 1.35; P>.05), children aged 6 to 10 years (OR 1.9; P>.05), and those with greater gross motor function involvement, classified in level iv and v according to the GMFCS (OR 1.60 and 1.11, respectively; P>.05). Burden was also higher in caregivers who were separated, divorced or widowed (OR 2.38; P>.05), and those with incomplete basic secondary education (OR 2.86; P>.05).

CONCLUSIONS

This study suggests that perceived burden among caregivers varies mainly according to the age, sex, and disability of patients with cerebral palsy, as well as the age, marital status and educational level of the caregiver.

Quality improvement study on early recognition and intervention of caregiver burden in a tertiary hospital

Background

Caregivers play a crucial role in taking over the important task of looking after patients post-hospitalisation. Caregivers who are unfamiliar with patients’ post-discharge care often experience caregiver stress, while patients may see deterioration in their condition. As caregivers are our core partners in healthcare, it is therefore necessary for patient navigators to recognise, assess and address caregivers’ needs or burden as early as on admission to hospital. Patient navigators are trained registered nurses whose main role is to provide patients and caregivers with personalised guidance through the complex healthcare system.

Objectives

This quality improvement study examined the efficacy of using the Zarit Burden Interview as a tool in helping patient navigators recognise caregiver burden early and the effectiveness of targeted interventions on caregiver burden.

Methods

Various quality improvement tools were used. Eighty-six patient-caregiver dyads who met the inclusion criteria were enrolled. Informal caregivers were assessed for caregiver burden using the Zarit Burden Interview during hospital admission (T0) and again at 30 days postdischarge (T1), post-intervention.

Results

There was significant improvement in the Zarit Burden mean scores from T0 to T1 reported for the 80 dyads who completed the study, even after adjusting for covariates (T0 mean=11.08, SD=7.64; T1 mean=2.48, SD=3.36, positive ranks, p<0.001). Highest burden identified by most caregivers were the personal strain; trying to meet other responsibilities and uncertain about what to do in caring for their loved one. By recognising the different aspects of caregiver burden early, patient navigators were able to focus their interventions.

Conclusion

Early recognition of caregiver burden and targeted interventions were found to be effective at reducing caregiver burden in a tertiary hospital.

Effect of lower extremity amputation on caregiving burden in caregivers of patients with diabetic foot: Prospective cohort study

Lower extremity amputation as a treatment of diabetic foot ulcer is probably a major burden for the patient's family and friends, who typically act as caregivers and support the patient in coping with the physical disabilities and emotional distress. In the present prospective study, we investigated the effects of different lower extremity amputation levels for diabetic foot ulcer treatment on caregivers of patients with diabetes using the Zarit Burden Interview (ZBI-12) scale. Patients with diabetic foot ulcers who underwent unilateral major amputation (above-below knee) and minor amputation of foot (heel sparing) and their caregivers were requested to volunteer to participate in this study from June 2016 to December 2018. The ZBI-12 form was completed immediately preoperatively and 3 and 6 months after postoperatively. In the minor amputation group, the mean age of the 51 patients was 72.1 years. In the major amputation group, the mean age of the 88 patients was 73.7 years. Both groups of caregivers of patients with minor amputation and major amputations showed a significant improvement in ZBI-12 score when compared preoperatively and at 3- and 6-month follow-up visits. The mean ZBI-12 score was significantly higher in the major than in the minor amputation group in preoperative and all postoperative visits. The absence of the ankle joint in the below- or above-knee amputation renders it more difficult for the amputee to quickly learn the use of prosthesis, thereby increasing the burden of the patient and caregivers. We found that lower extremity amputation for the treatment of chronic diabetic foot ulcers has significantly favourable effect on the caregiver burden, and thereby heel sparing was considerably more effective for the caregiver burden.

Caregivers of Older Persons in Jamaica: Characteristics, Burden, and Associated Factors

OBJECTIVE

The objective of this study was to determine and characterize caregiver burden among caregivers of community-dwelling older persons in Jamaica.

METHOD

A nationally representative cross-sectional study was done among persons providing noninstitutional care for a single person (≥60 years). The Zarit Burden Interview (ZBI) and a structured questionnaire were administered to 180 caregivers from four geographic health regions.

RESULTS

The ZBI scores ranged from 0 to 56 (median = 15). Independently associated factors were relationship to care recipient and age. Children/grandchildren had higher caregiver burden scores than formally employed caregivers (odds ratio = 2.9: 95% confidence interval: [1.02, 8.34]). Compared with caregivers 35 to 44 years, those aged 45 to 65 were almost 5 times more likely to report higher caregiver burden scores.

CONCLUSION

Caregiver burden as identified by the ZBI was low. Age (45-65 years) and being the child/grandchild of the care recipient were independently associated with greater caregiver burden. Interventions to address caregiver burden must embrace strategies that recognize that these factors.

Significant Burden and Psychological Distress Among Caregivers of Children With Nephrotic Syndrome: A Cross-Sectional Study

Background:

Childhood nephrotic syndrome (NS) follows a chronic course in most children. However, little is known about the psychosocial burden of NS on the caregivers despite evidence that caregiver burden or impairment in their well-being may alter the outcome of chronic childhood illnesses.

Objectives:

To determine the frequency and predictors of significant caregiver burden and psychological distress among caregivers of children with NS.

Design:

A cross-sectional study.

Setting:

Two pediatric nephrology clinics in Lagos, Nigeria.

Patients:

We included primary caregivers of children with idiopathic NS for at least 6 months.

Measurements:

The primary outcomes were psychological distress and significant caregiver burden among caregivers.

Methods:

We interviewed caregivers using the 12-item General Health Questionnaire (GHQ-12) and the 6-item Zarit Burden Interview (ZBI-6). The GHQ-12 scores ≥ 3 and ZBI-6 scores ≥ 6 indicated psychological distress and significant caregiver burden, respectively.

Results:

The caregivers were mostly mothers (77.9%) and married (92.4%), whereas the children (n = 172) were mainly male (65.1%). Most of the children (n = 152; 88.4%) had steroid-sensitive NS including 24 (14%) children with frequent relapses or steroid dependence and 20 (11.6%) with steroid-resistant NS. Of the 172 caregivers, 53 (30.8%) and 30 (17.4%) reported psychological distress and significant burden, respectively. Caregivers of children in relapse had adjusted an odds ratio (aOR) with 95% confidence interval (CI) of 2.45 (1.05-5.67) and 3.30 (1.22-8.92) of psychological distress and significant caregiver burden, respectively. Furthermore, caregivers of male children and those who needed help paying for health care had an aOR of 4.61 (1.34-15.68) and 3.06 (1.06-8.87) of significant caregiver burden, respectively.

Limitations:

The study was limited by its cross-sectional design and the use of generic rather than disease-specific instruments.

Conclusion:

One in every 6 caregivers of children with idiopathic NS reported significant caregiver burden, and it was associated with psychological distress. Our findings underscore the need for psychosocial support for caregivers of children with NS, especially those with identifiable vulnerability.

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.

Predictors of Burden of Care Among Caregivers of Drug-Naive Children and Adolescents With ADHD: A Cross-Sectional Correlative Study From Muscat, Oman

OBJECTIVE

the study assessed the prevalence of burden of care among caregivers of children with ADHD in Oman. A related aim is to explore the predictors of the burden of care, subtypes of ADHD, and socio-demographic factors.

METHOD

Arabic version of the Zarit Burden Interview (ZBI) was administered to 117 caregivers of drug-naive children with ADHD. Sociodemographic background and clinical data were gathered from medical records and from the attending caregivers themselves. The ADHD symptoms were grouped under three categories : hyperactive, inattentive, or mixed.

RESULTS

the prevalence of the burden of care was estimated to be 34%. Income levels and the child's ADHD diagnosis being of "mixed" type have significant impact on the burden of care.

CONCLUSION

the results of this study indicate that the prevalence of the burden of care among the caregivers of ADHD children in Oman is comparable with that in the other regions of the world.

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.

Multidimensional Care Burden in Parkinson-Related Dementia

BACKGROUND AND OBJECTIVE

Providing care to people with Parkinson-related dementia (PwPRD) may result in significant stress, strain, and burden for life partners. A common measurement of life partner burden is the Zarit Burden Interview (ZBI), which considers "burden" as a unitary concept; however, burden is highly complex and most likely comprises several dimensions. This study aimed to explore the factor structure of the ZBI in life partners of PwPRD and to examine the relationships among the emerging factors and the demographic and clinical features.

METHODS

Life partners of PwPRD participated in home-based quantitative assessments and self-completed postal questionnaires. The assessment battery included ZBI, measures of relationship satisfaction, mood, stress, resilience, health, quality of life, feelings related to care provision, and sociodemographic questions. Data on PwPRDs' motor and neuropsychiatric symptom severity were also elicited in home-based assessments.

RESULTS

An exploratory factor analysis (principal axis factoring) of ZBI, conducted with 127 life partners, revealed five burden dimensions: social and psychological constraints, personal strain, interference with personal life, concerns about future, and guilt. These burden factors were associated with lower relationship satisfaction, mental health, and resilience, and higher stress, anxiety, depression, resentment, negative strain, and PwPRD motor severity. In multiple linear regression analyses, where each factor score was the dependent variable, stress, negative strain, and resentment emerged as significant predictors of specific burden dimensions.

CONCLUSIONS

Burden is a complex and multidimensional construct. Interventions should address specific types of burden among life partners of PwPRD to support couples' relationships and maintain quality of life.

Imaging Care Requirements: Use of Functional Neuroimaging to Predict Dementia Caregiver Burden

Background

Dementia caregivers frequently report high stress, with increased burden associated with worse outcomes for both patients and caregivers. Although many studies relate clinical phenotypes to burden, the relationship between imaging pathology and burden, irrespective of diagnosis, is unknown. This study investigated the relationship between caregiver burden and patient regional cerebral blood flow in dementia.

Methods

Seventy-sev en patients with cognitive impairment undergoing brain perfusion single-photon emission computed tomography imaging in normal clinical care and their caregivers were recruited. Caregiver burden was ranked from “little” to “severe” using the Zarit Burden Interview and perfusion values extracted from the patient images for predefined regions of interest. The associations between burden score and regional function on imaging were tested.

Results

Burden score was significantly higher for caregivers of patients with abnormal perfusion compared to those with normal perfusion in the left and right frontal, right parietal, and right temporal lobes. No difference in burden was found in the left parietal or temporal groups. Correlations showed that a higher caregiver burden was associated with lower patient perfusion scores in the same regions.

Conclusion

Caregiver burden is strongly related to the extent of frontal or right-predominant parietal or temporal lobe dysfunction. Regional abnormality on perfusion imaging can be used to facilitate identification of individuals who are likely to create a high burden on caregivers.

Trajectories of Multidimensional Caregiver Burden in Chinese Informal Caregivers for Dementia: Evidence from Exploratory and Confirmatory Factor Analysis of the Zarit Burden Interview

BACKGROUND

Despite its popularity, the latent structure of 22-item Zarit Burden Interview (ZBI) remains unclear. There has been no study exploring how caregiver multidimensional burden changed.

OBJECTIVE

The aim of the work was to validate the latent structure of ZBI and to investigate how multidimensional burden evolves with increasing global burden.

METHODS

We studied 1,132 dyads of dementia patients and their informal caregivers. The caregivers completed the ZBI and a questionnaire regarding caregiving. The total sample was randomly split into two equal subsamples. Exploratory factor analysis (EFA) was performed in the first subsample. In the second subsample, confirmatory factor analysis (CFA) was conducted to validate models generated from EFA. The mean of weighted factor score was calculated to assess the change of dimension burden against the increasing ZBI total score.

RESULTS

The result of EFA and CFA supported that a five-factor structure, including role strain, personal strain, incompetency, dependency, and guilt, had the best goodness-of-fit. The trajectories of multidimensional burden suggested that three different dimensions (guilt, role strain and personal strain) became the main subtype of burden in sequence as the ZBI total score increased from mild to moderate. Factor dependency contributed prominently to the total burden in severe stage.

CONCLUSION

The five-factor ZBI is a psychometrically robust measure for assessing multidimensional burden in Chinese caregivers. The changes of multidimensional burden have deepened our understanding of the psychological characteristics of caregiving beyond a single total score and may be useful for developing interventions to reduce caregiver burden.

Caregiver Burden in Semantic Dementia with Right- and Left-Sided Predominant Cerebral Atrophy and in Behavioral-Variant Frontotemporal Dementia

Background

Caregiver burden is a serious concern for family caregivers of dementia patients, but its nature is unclear in patients with semantic dementia (SD). This study aimed to clarify caregiver burden for right- (R > L) and left-sided (L > R) predominant SD versus behavioral-variant frontotemporal dementia (bvFTD) patients.

Methods

Using the Japanese version of the Zarit Burden Interview (ZBI) and the Neuropsychiatric Inventory, we examined caregiver burden and behavioral and psychological symptoms of dementia (BPSD) in 43 first-visit outpatient/family caregiver dyads (bvFTD, 20 dyads; SD [L > R], 13 dyads; SD [R > L], 10 dyads).

Results

We found a significant difference in ZBI score between the 3 diagnostic groups. Post hoc tests revealed a significantly higher ZBI score in the bvFTD than in the SD (L > R) group. The ZBI scores in the SD (L > R) and SD (R > L) groups were not significantly different, although the effect size was large. Caregiver burden was significantly correlated with BPSD scores in all groups and was correlated with activities of daily living and instrumental activities of daily living decline in the bvFTD and SD (R > L) groups.

Conclusion

Caregiver burden was highest in the bvFTD group, comparatively high in the SD (R > L) group, and lowest in the SD (L > R) group. Adequate support and intervention for caregivers should be tailored to differences in caregiver burden between these patient groups.

Worry About Caregiving Performance: A Confirmatory Factor Analysis

Recent studies on the Zarit Burden Interview (ZBI) support the existence of a unique factor, worry about caregiving performance (WaP), beyond role and personal strain. Our current study aims to confirm the existence of WaP within the multidimensionality of ZBI and to determine if predictors of WaP differ from the role and personal strain. We performed confirmatory factor analysis (CFA) on 466 caregiver-patient dyads to compare between one-factor (total score), two-factor (role/personal strain), three-factor (role/personal strain and WaP), and four-factor models (role strain split into two factors). We conducted linear regression analyses to explore the relationships between different ZBI factors with socio-demographic and disease characteristics, and investigated the stage-dependent differences between WaP with role and personal strain by dyadic relationship. The four-factor structure that incorporated WaP and split role strain into two factors yielded the best fit. Linear regression analyses reveal that different variables significantly predict WaP (adult child caregiver and Neuropsychiatric Inventory Questionnaire (NPI-Q) severity) from role/personal strain (adult child caregiver, instrumental activities of daily living, and NPI-Q distress). Unlike other factors, WaP was significantly endorsed in early cognitive impairment. Among spouses, WaP remained low across Clinical Dementia Rating (CDR) stages until a sharp rise in CDR 3; adult child and sibling caregivers experience a gradual rise throughout the stages. Our results affirm the existence of WaP as a unique factor. Future research should explore the potential of WaP as a possible intervention target to improve self-efficacy in the milder stages of burden.

Clinical routine assessment of palliative care symptoms and concerns and caregiver burden in glioblastoma patients: an explorative field study

The implementation of self-reported outcome measurements into clinical routine was tested to help facilitate early access to palliative care (PC) for glioblastoma (GBM)-patients. Measures detail PC symptoms and concerns and caregiver burden. Between January 2014 and December 2016, a total of 337 GBM-patients were discussed during meetings of the neuro-oncology tumor board to examine further treatment options. Each patient, along with their caregivers, was requested to participate in self-assessment using the palliative outcome scale (POS) and the Zarit Burden Interview (ZBI). Analyses encompassed summary statistics, non-parametric tests, visual graphic analysis, content analysis and assessing the utilization of the specialized PC consulting service (SPCCS). Ninety-five (28%) GBM-patients and 71 (21%) caregivers completed the self-assessment. Of these, 20 patients and 12 caregivers repeated the assessment at least once more during follow-up. POS total scores were similar in the group of patients with initial diagnosis [10 (0-31)] and those with later disease stages like recurrent diagnosis [9 (0-25)], but ZBI total scores differed [14 (0-51) vs. 24 (2-62)]. Single item analysis demonstrated that anxiety and worries about the future predominated. Caregivers were torn between high engagement in caring and feeling overburdened. Still, requests for the SPCCS showed no increase. Actual implementation of measures like POS and ZBI for detecting PC concerns and caregiver burden with GBM-patients in the field remains challenging as indicated by the limited response rate and lack of increased requests for the SPCCS. Modified clinical routines including strengthening awareness of PC, and allowing proxy-assessment might help to overcome barriers.

Burden among Family Caregivers of Dementia in the Oldest-Old: An Exploratory Study

Background

With >85 years, the fastest growing age segment in developed countries, dementia in the oldest-old is projected to increase exponentially. Being older, caregivers of dementia in oldest-old (CDOO) may experience unique challenges compared with younger-age groups. Thus, we aim to explore demographic characteristics and burden pattern among CDOO.

Methods

We studied 458 family caregiver-patient dyads attending an outpatient memory clinic. We classified patients into three age-groups: <75, 75–84, and ≥85 years. We measured caregiver burden using the Zarit Burden Interview (ZBI) 4-factor structure described by Cheah et al. (1). We compared care recipient characteristics, caregiver demographics, and ZBI total/factors scores between the three age-groups, and performed 2-way analysis of variance (ANOVA) to ascertain the effect of age-group by disease severity interaction.

Results

Oldest-old care recipients were more impaired in cognitive function and instrumental ADL; there was no difference in behavior and basic ADL. Compared with the other two age-groups, CDOO were older (mean age: 50.4 vs 55.5 vs 56.8 years, P < 0.01), and overwhelmingly adult children (85.9%) as opposed to spouses (5.3%). CDOO also had higher ZBI total score, role strain, and personal strain (all P < 0.05). However, there was no difference in worry about performance scores. 2-way ANOVA did not reveal significant age-group by disease severity interaction for ZBI total and factor scores, although distinctive differences were seen between role/personal strain with worry about performance in mild cognitive impairment and very mild dementia.

Conclusion

Our study highlighted that CDOO were mainly older adult children who experienced significant role and personal strain independent of disease severity while caring for their family member with more impaired cognitive and physical function. These results pave the way for targeted interventions to address the unique burden faced by this rapidly growing group of caregivers.

Care recipients' physical frailty is independently associated with subjective burden in informal caregivers in the community setting: a cross-sectional study

BACKGROUND

Physical frailty is associated with significant morbidity and mortality in community-dwelling older adults. Burden in informal caregivers of older adults causes significant physical and psychological distress. However, the relationship between these two clinical phenomena has not been extensively studied. This cross-sectional study evaluated the relationship between physical frailty of community-dwelling older adults attending an outpatient geriatric clinic and the subjective burden reported by their informal caregivers.

METHODS

We measured the following characteristics of 45 patient-caregiver dyads attending an outpatient geriatric assessment clinic: Physical frailty using the Fried Frail Scale (FFS); self-reported independence in activities of daily living (ADL) using the Katz Index; clinical diagnosis of dementia; and subjective caregiver burden using the short 12-item version of the Zarit Burden Interview (ZBI). Multivariable linear regression was performed with FFS, Katz Index score, gender, age, and diagnosis of dementia as independent variables, and ZBI score as the dependent variable.

RESULTS

Only physical frailty significantly predicted caregiver burden (β = 8.98 95% confidence interval [CI]: 2.15, 15.82).

CONCLUSIONS

Physical frailty is independently associated with caregiver burden in a population of community-dwelling older adults. Despite limitations related to sample size and lack of data about caregiver characteristics, this study suggests that the relationship between physical frailty and caregiver burden merits further study.

Measuring burden in dementia caregivers: Confirmatory factor analysis for short forms of the Zarit Burden Interview

INTRODUCTION

To examine the psychometric properties of different short versions of the Zarit Burden Interview (ZBI), and to find an efficient and valid short version for clinical use among dementia caregivers.

MATERIALS AND METHODS

A total of 270 Taiwanese dementia caregivers filled out the full form of the ZBI, which contains 22 items. Using the 22-item ZBI, we used confirmatory factor analysis (CFA) to calculate the fit indices of all proposed short versions with various items to determine useful short versions. Additional associations between each useful short version and informal care hours, as well as subjective financial situations, were examined to understand their concurrent validity.

RESULTS

Based on the CFA results, three short versions of the ZBI, performed excellently (4-item version: comparative fit index [CFI]=1.000, Tucker-Lewis index [TLI]=1.035, standardized root mean square residual [SRMR]=0.019, and root mean square error of approximation [RMSEA]=0.000; 8-item version: CFI=0.970, TLI=0.958, SRMR=0.045, and RMSEA=0.065; 12-item version: CFI=0.959, TLI=0.950, SRMR=0.053, and RMSEA=0.075). In addition, the 12-item ZBI, as compared with other versions, had a higher correlation with the number of informal care hours. The 12-item ZBI was also highly correlated with the original 22-item ZBI (r=0.952).

CONCLUSIONS

We found the 12-item ZBI to be a promising measure for healthcare providers to assess the burden of dementia caregivers quickly and efficiently.

Care participation and burden among informal caregivers of older adults with care needs and associations with dementia

BACKGROUND

Few studies have estimated care burden in large, representative, multi-ethnic Asian population-based informal caregivers of older adults with care needs. This study describes informal caregivers' care participation for a population-based sample of older adults with care needs in Singapore, investigates differences by dementia status, and examines correlates of caregivers' burden.

METHODS

Data collected from 693 pairs of older adults, aged 60 to 100 years, having any care needs, and their informal caregivers, who were aged 21 to 88 years, closely involved in their care and "knew the older resident best," and were interviewed during a cross-sectional national survey, were used. Clinical characteristics of older adults, including behavioral and psychological symptoms of dementia (BPSD) and dementia diagnosis, care needs, and socio-demographic characteristics of participants were obtained. Care burden was assessed with the Zarit Burden Interview.

RESULTS

Informal caregivers' participation was highest in activities related to communication (35.1%), feeding (32%), and bathing (21.1%). Among the older adults with any care need, 356 (51.4%) had dementia. Care burden was significantly associated with married caregivers (odds ratio (OR) 2.4 vs. never married), when their relative belonged to a younger cohort (OR 2.5 vs. >84 years), needed care much of the time (OR 2.5 vs. no care needed), exhibited BPSD (OR 3.5 vs. no BPSD), and had dementia (OR 2.52 vs. no dementia).

CONCLUSIONS

Factors related to older adults--more care needs, presence of BPSD, and dementia--were significant contributors to informal caregivers' burden, and these should be considered while planning interventions to alleviate care burden.

Difference in determinants of caregiver burden between amnestic mild cognitive impairment and mild Alzheimer's disease

Care for the disabled elderly can be stressful and exhausting, especially in cases of dementia. There have been a number of studies on the dementia caregiver burden, but studies focusing on differences by stages of the disease are rare. The caregiver burden of 85 caregivers of patients with amnestic mild cognitive impairment (aMCI) and 106 caregivers of patients with mild Alzheimer׳s disease (AD) was evaluated by the short version of the Japanese version of the Zarit Burden Interview (sZBI). The caregiver burden in mild AD was more severe than that in aMCI. In mild AD, the risk factors of caregiver burden were neurobehavioral symptoms and disturbances instrumental activities of daily living (IADL), whereas the risk factors in aMCI were neurobehavioral symptoms and memory dysfunction. The severity of dementing disease affects the caregiver burden, and somewhat different factors contribute to the burden at different stages. We should pay attention to different factors in evaluating and reducing the caregiver burden in aMCI and mild AD.

Use of Zarit Burden Interview in analysis of family caregivers' perception among Taiwanese caring with hospitalized relatives

This study was conducted to examine the relationships between family caregivers' perception of caregiving and its influencing factors among Taiwanese with hospitalized relatives. The study used a cross-sectional and descriptive correlational design. A convenience sample of 200 primary caregivers of hospitalized patients diagnosed with cancer, stroke and chronic illness was recruited in a Taiwanese Medical Center; this focus was chosen because cancer, stroke and chronic illness generally require long term care. Data were collected by structured questionnaires. Pearson product-moment correlation and stepwise multiple regression analyses were used to analyse the results of this study. Family caregivers who lacked family support and whose patients' ADL (activities of daily living) dependency was increasing experienced a greater caregiving burden. Family caregivers who had better psychological well-being, better quality of relationship and more caregiving knowledge experienced a lower caregiving burden. Quality of relationship, lack of family support and patients' ADL dependency accounted for 43% of the Zarit Burden Interview variance. The results indicated that family caregivers' perception of caregiving included sacrifice, strain, embarrassment, anger and loss of control. It is vital for nurses to understand these caregiving perceptions and their related factors to provide a holistic care plan.
