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

Psychological screening of significant others during spinal cord injury rehabilitation

DESIGN

Retrospective cohort study.

OBJECTIVE

Determine the course of burden and psychological distress of significant others (SOs) during initial spinal cord injury (SCI) rehabilitation and to predict the caregiver's burden at discharge with characteristics of SOs and persons with SCI (PSCIs) at the start of rehabilitation.

SETTING

Rehabilitation center Sint Maartenskliniek, Nijmegen, The Netherlands.

METHODS

All PSCIs admitted for initial rehabilitation between October 2020 and December 2022 were included. One of their SOs were asked to complete a set of screening questionnaires, collected in our routine context of care.

RESULTS

A total of 181 PSCIs (62% male, average age 60 years, 80% incomplete SCI, 60% paraplegia and 32 days after injury) and 158 SOs (40% male, average age 57 years) were screened at admission, and 145 and 93 at discharge, respectively. For SOs, the average caregiver's burden and feelings of depression and anxiety did not change during admission. The caregiver's burden score at discharge was best predicted by the burden score at admission, explaining 20% (P < 0.001) of the variance. An additional 13% (P = 0.02) of the variance was explained by other SO and PSCI variables gathered in this study.

CONCLUSION

The caregiver's burden in this group of SOs during rehabilitation, was higher than that of a representative group in the chronic phase. On both assessments, around 20% scored above the cutoff. Scores of psychological distress are comparable to former studies. Standard screening of SOs during initial SCI rehabilitation is important to help the interdisciplinary team identify SOs at risk, and target their treatment during inpatient rehabilitation.

Development of a short form of the Japanese version of the Caregiver Reaction Assessment (CRA-J-10) among informal caregivers of older adults

AIM

To support informal caregivers, a simple assessment tool capturing the multidimensional nature of caregiving experiences, including negative and positive aspects, is required. We developed a short form of the Japanese version of the Caregiver Reaction Assessment (CRA-J), a multidimensional assessment scale for caregiver experiences.

METHODS

The internet survey involved 934 Japanese informal caregivers aged 20-79 years (mean age = 58.8 years; 50.2% women) who completed questionnaires, including the CRA-J 18 items (CRA-J-18), consisting of five domains, such as impacts on schedule and finances and positive experiences of caregiving. A 10-item short version of the CRA-J (CRA-J-10; 0-50 points), which was prepared by selecting the two items with the highest factor loadings from each domain, was tested for model fit by confirmatory factor analysis (CFA) and was analyzed for correlations with the CRA-J-18, Zarit Burden Interview (ZBI), Positive Aspects of Caregiving Scale (PACS), Patient Health Questionnaire-9 (PHQ-9), and WHO-Five Well-Being Index (WHO-5). The area under the curve (AUC) in the receiver operating characteristic was evaluated as discriminability for depressive symptoms (PHQ-9 ≥ 10 points).

RESULTS

The CFA indicated a good model fit in the CRA-J-10. The CRA-J-10 correlated well with the CRA-J-18 and other variables (CRA-J-18, r = 0.970; ZBI, r = 0.747; PACS, r = -0.467; PHQ-9, r = 0.582; WHO-5, r = -0.588) and showed good discriminant performance for the presence of depressive symptoms (AUC = 0.793, 95% confidence interval = 0.762-0.823).

CONCLUSIONS

The CRA-J-10 allows a simple assessment of caregiver experiences, helping support informal caregivers. Geriatr Gerontol Int 2024; 24: 290-296.

Influence of preparedness on caregiver burden, depression, and quality of life in caregivers of people with disabilities

Introduction

Caregiver preparedness is defined as the perceived preparation of caregivers to care for the physical and emotional needs of the patient.

Purpose

This study investigated caregiver preparedness and its influences on caregiver burden, depression, and quality of life (QoL) in caregivers of individuals with disabilities.

Methods

We conducted a multicenter cross-sectional survey study on caregivers caring for patients with disabilities. Sociodemographic characteristics were collected via questionnaires. The Preparedness for Caregiving Scale (PCS), Burden Interview (BI), Center for Epidemiologic Studies Depression Scale (CES-D), and EuroQol-Visual Analogue Scale (EQ-VAS) were administered.

Results

A total of 151 caregivers were enrolled. The mean age of caregivers was 53.7 ± 12.4 years, and 80.8% were female. The majority of participants were the main caregivers of patients with stroke, spinal cord injury, or traumatic brain injury. The mean PCS score was 2.1 ± 0.9, demonstrating significant relationships with BI (r = -0.512, p < 0.001), CES-D (r = -0.622, p < 0.001), and EQ-VAS (r = 0.441, p < 0.001). The CES-D was significantly associated with the PCS after controlling other variables. However, PCS did not show any correlation with the duration of caregiving or amount of time spent per day on caregiving.

Discussion

The clinical implications of this study are that higher caregiver preparedness is a predictor of less caregiver burden and depression, and better QoL. However, preparedness did not increase as the duration or time spent on caregiving was extended. Therefore, efforts to enhance the caregivers' preparedness are required to reduce caregiver burden and improve health outcomes for both caregivers and patients.

Development and Psychometric Properties of the Caregiver Burden Scale in Polish Caregivers of Stroke Patients

Purpose

Most stroke patients require long-term care of their family members. Excessive care burden entails several negative consequences; therefore, the severity of the burden should be periodically assessed. For this purpose, valid multidimensional measures are needed. Our study, which is a part of a larger research project, aims to translate and evaluate the psychometric properties of the Polish Caregiver Burden Scale (CBS) in relation to construct validity and internal consistency in caregivers of the patients after stroke.

Patients and Methods

The sample of this cross-sectional observational study consisted of 366 informal caregivers to consecutive first-ever stroke survivors. The five-factor Polish CBS and the Hospital Anxiety and Depression Scale (HADS) were administered during the home visits at three to six months after patients’ hospitalisation. Exploratory (EFA), confirmatory (CFA) factor analyses and a net analysis were performed to investigate the internal structure and a factorial construct validity of the CBS. Correlation analyses between the CBS and the HADS were carried out to examine convergent validity. Cronbach’s alpha and item-total correlation were applied to assess internal consistency.

Results

Three out of five factors identified by EFA were similar to the original indices of the CBS, while the remaining two deviated from the original structure of the CBS. The CFA five-factor model represented an acceptable fit (confirmatory fit index, CFI = 0.96, root mean square error, RMSEA = 0.04) but only after a modification. All subscale scores of the CBS were positively correlated with the HADS, supporting the convergent validity. Cronbach’s alpha coefficients for the overall scale (0.92) and all subscales (0.72–0.87) except one (0.69) and item-total correlation results indicated good internal consistency.

Conclusion

The Polish version of the CBS showed acceptable internal consistency and good convergent validity. Factorial validity and structural integrity were partially supported. The interrelationships between the CBS subdomains, their partial mutual contamination, and the scale’s non-orthogonal structure should be considered when interpreting the results of further studies using this version of the scale.

A brief psychometric and clinimetric evaluation of self-report burden and mental health measures completed by care partners of people with Parkinson's-related dementia

This report describes the evaluation of the psychometric and clinimetric properties of nine self-report measures completed by informal care partners of individuals with mild cognitive impairment or dementia in Parkinson's disease and dementia with Lewy bodies. One hundred thirty-six care partners completed measures on relationship satisfaction, burden, stress, mood, resilience, health, quality of life, and feelings related to care provision. Psychometric properties, such as internal consistency, convergent validity, floor and ceiling effects, completion rate and data missingness, as well as clinimetric properties, such as time to administer, ease of scoring, readability and availability of the scales, were examined. Additionally, the design of the measure development studies was assessed with the 2018 COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) Risk of Bias checklist. Participants were mostly married women (>85%) with a mean age of 69.4 years. The methodological quality of the design of all measure development studies was "inadequate." Five widely applied measures (Zarit Burden Interview, Hospital Anxiety and Depression Scale, Short Form 12 Health Survey, Relatives' Stress Scale, and EuroQoL-5D) and two less researched instruments (Brief Resilience Scale and Relationship Satisfaction Scale) had high internal consistency and completion rates, moderate to strong convergent validity, low missingness and floor effects, and excellent clinical utility ratings. Two scales (Dyadic Relationship Scale and Family Caregiving Role) received poor psychometric ratings, and their usage among informal care partners is not recommended. In conclusion, well-validated and widely used measures received strong psychometric and clinimetric ratings. Future studies are required to determine the most reliable, valid and robust caregiver-reported measures.

Caregiver Burden in Multiple Sclerosis: Recent Trends and Future Directions

Purpose of Review

In spite of recent advances in treatment, many people with multiple sclerosis (MS) require ongoing care and support. Informal caregivers can experience burden as a result of their role, with possible implications for quality of life (QOL). We review recent research examining MS caregiver experience to (1) understand current risk factors for caregiver burden and (2) identify possible strategies for increasing carer well-being.

Recent Findings

MS caregiver experience is highly variable and can be predicted by a variety of care recipient, caregiver and contextual factors. Burden is not the only characteristic associated with care, with positive consequences also reported. Emerging research suggests a number of ways in which carers can be better supported.

Summary

Identifying and meeting the needs of MS caregivers offers the best way of delivering tailored support. Future research should focus on the development of psychosocial supports, while acknowledging the needs of those caring for different MS patient populations.

Safety and Feasibility of Various Functional Electrical Stimulation Cycling Protocols in Individuals With Multiple Sclerosis Who Are Nonambulatory

Objective

To examine the safety, feasibility, and response to functional electrical stimulation (FES) cycling protocols requiring differing levels of effort in people with multiple sclerosis (MS) who are nonambulatory.

Design

Pilot study with pre-post intervention testing.

Setting

Outpatient clinic setting of a long-term acute care hospital.

Participants

Individuals (N=10) with MS (6 men; mean age 58.6±9.86y) who use a wheelchair for community mobility. Participants’ Expanded Disability Status Scale score ranged from 6.5 to 8.5 (median 7.5).

Intervention

Participants performed 3 or 4 FES cycling protocols requiring different levels of volitional effort during 6-8 testing sessions.

Main Outcome Measures

The primary outcome was safety, measured by adverse events and increase in MS symptoms, all assessed throughout, immediately post- and 1 day postsession. FES cycling performance for each protocol was also recorded. Exploratory outcome measures collected before and after all testing sessions included functional assessment of MS, MS Impact Scale, Exercise Self Efficacy Scale, Patient Health Questionnaire-9 item, and the Zarit Caregiver Burden Scale.

Results

All participants (4 women, 6 men) completed all testing sessions. There were no serious adverse events or differences in vitals or symptoms between protocols. Two participants had an isolated episode of mild hypotension. Changes in pain, spasticity, and fatigue were minimal. Five participants were able to cycle for 30 minutes and completed interval training protocols requiring increasing difficulty. The remainder cycled for <3 minutes and completed a rest interval protocol. There was modest improvement on the exploratory outcome measures.

Conclusions

People with MS who use a wheelchair for community mobility can safely perform FES cycling requiring more effort than previously reported research. Therefore, the individuals may experience greater benefits than previously reported. Further study is required to better understand the potential benefits for optimizing function and improving health in people with MS.

•

People with multiple sclerosis who are nonambulatory can safely perform functional electrical stimulation (FES) cycling using parameters requiring more effort.

•

FES cycling may offer an opportunity for increased exercise stimulus or neuromuscular training if individuals are adequately challenged using an appropriate cycling protocol.

Longitudinal changes on the quality of life in caregivers of type 2 diabetes amputee patients

PURPOSE

To explore changes in the quality of life of caregivers of amputees due to type 2 diabetes ten months after amputation.

METHODS

This is a longitudinal study with three moments of evaluation (T1: one month after surgery, T2: 7 months, T3: 10 months). The sample comprised 110, 101, and 84 caregivers of amputated patients with type 2 diabetes. Caregivers answered a Socio-demographic questionnaire; the Self-Assessment Caregiver; the Family Disruption from Illness Scale; and the Short Form Health Survey (SF36).

RESULTS

Stress levels were not significantly reflected in changes on mental quality of life over time, except in the caregivers who presented less stress, emphasizing the adverse role of stress when experienced on a continuous basis for ten months on the caregivers' mental well-being. Caregivers presented greater number of physical symptoms at T2 that decreased at T3.

CONCLUSIONS

According to the results, in order to promote caregivers' physical and mental quality of life, it would be important to evaluate stress levels especially in patients who presented somatic complaints.
