Performance of the Modified Caregiver Strain Index in a Sample of Black and White Persons Living With Dementia and Their Caregivers

BACKGROUND AND OBJECTIVES

This study examined the performance of the Modified Caregiver Strain Index (MCSI) in a sample of Black and White caregivers of persons living with dementia.

RESEARCH DESIGN AND METHODS

Data on 153 dyads enrolled in the Care Ecosystem dementia care management program were analyzed, including sociodemographic variables, dementia severity, and caregiver burden and wellbeing. Factor structure, item-response patterns, and concurrent validity were assessed across racial groups.

RESULTS

Differences between Black and White caregivers included gender, dyad relation, and socioeconomic disadvantage. Factor structure and item loadings varied by racial cohort, with parameters supporting a 3-factor model. For Black caregivers, finances and work, emotional and physical strain, and family and personal adjustment items loaded together on individual factors. For White caregivers physical and emotional strain items loaded on separate factors, although personal and family adjustment items loaded with work and financial strain items. Item-level analysis revealed differences between groups, with Black caregivers endorsing physical strain to a greater degree (p = .003). Total MCSI scores were positively correlated with concurrent measures like the PHQ-9 (White: r = 0.67, Black: r = 0.54) and the GAD-2 (White: r = 0.47, Black: r = 0.4), and negatively correlated with self-efficacy ratings (White: r = -0.54, Black: r = -0.55), with a p < .001 for all validity analysis.

DISCUSSION AND IMPLICATIONS

The MCSI displayed acceptable statistical performance for Black and White caregivers of persons living with dementia and displayed a factor structure sensitive to cultural variations of the construct. Researchers results highlight the inherent complexity and the relevance of selecting inclusive measures to appropriately serve diverse populations.

Caregiver strain among patients of palliative care in Sri Lanka: validation of modified caregiver strain index - Sinhala version

BACKGROUND

Care givers of Palliated patients are at risk of adverse physical, psychosocial and emotional sequelae in varied nature. Efficient and valid assessment tools facilitate early detection to take corrective measures. The Modified Caregiver Strain Index (MCSI), composed of domains associated with caregiver strain is a simple and brief tool that can be used in both clinical and field settings. This study aimed to adapt and validate this in order to cater effective palliative care services in Sri Lanka.

METHODS

After cross-cultural adaptation, 200 primary caregivers in 3 teaching hospitals were recruited. The internal consistency, item-total correlations, of the 13-item S-MCSI were performed. The criterion validity was assessed by Pearson correlation between the total scores of S-MCSI, the Karnofky Performance Scale and the Barthel index. Construct validity was determined by the principal component analysis keeping the Varimax with Keiser normalization as the rotation method. The Kaiser-Meyer-Olkin test (KMO) and Bartlett's test of sphericity statistics were also performed to determine the adequacy of the sample and correlations between items, respectively. The number of factors was determined by the Scree plot, percentage of variance explained by each component and number of Eigen values over 01 (Kaiser-Guttman rule).

RESULTS

The total MCSI score ranged 0 to 26. The overall Cronbach's alpha of the 13-item questionnaire was 0.80 while item-total corrections ranged 0.34 to 0.62, exception of one item (0.11). Inverse correlations were demonstrated in total scores of MCSI and Karnofky Performance Scale (r =- 0.32, p < 0.001) and Barthel index (r =-0.34, P < 0.001). A Kaiser-Meyer-Olkin value of 0.79 (p < 0.001) for Bartlett's test indicated adequate sampling and nonlinearity of factors. The Scree plot showed a three-factor structure explaining 57% of the variation. Items regarding personal wellbeing of caregiver loaded together while the effects on the family loaded separately. Adjustment of personal concerns and family issues along with time alteration grouped as the third factor.

CONCLUSIONS

The study showed that the Sinhala version of MCSI has adequate psychometric properties and reliability to be used as a validated tool to estimate the caregiver burden within a short time period for any health care workers.

The Modified Caregiver Strain Index in Black and White Dementia Caregivers at Hospital Discharge

OBJECTIVES

This study aimed to examine psychometric properties of the Modified Caregiver Strain Index (MCSI) in Black and White caregivers of persons living with dementia at hospital discharge.

METHODS

This was a cross-sectional study using baseline data of 423 family caregivers recruited from a cluster randomized clinical control trial. Factor structure, measurement invariance, and concurrent validity of the MCSI were analyzed. The moderating role of race on the relationship between MCSI score and anxiety, depression, and burden was also examined.

RESULTS

The two-factor model fits the data best and was invariant across race. Regarding concurrent validity, higher MCSI scores were significantly associated with higher scores on the (HADS-A; anxiety), (HADS-D; depression), and (ZBI; burden). Race moderated the relationship between MCSI score and anxiety, depression, and burden.

CONCLUSIONS

The MCSI is a valid tool to assess caregiver strain in Black and White caregivers of persons living with dementia during hospital discharge. Results suggest that the effect of MCSI score on anxiety, depression, and burden varies by race.

CLINICAL IMPLICATIONS

MCSI can be used by clinicians and service providers to help support the needs of Black and White caregivers of people living with dementia during post-hospital transition.

Validity and Reliability of the Caregiver Strain Index Scale in Women during the Puerperium in Spain

BACKGROUND

The objective of this study is to determine the validity and reliability of the Caregiver Strain Index (CSI) for women during the postpartum period. Methods: This is a validation study of a measurement instrument. This study includes 212 women over the age of 19 who gave birth from March to September 2019 in Maternal and Child Hospital of Jaén (Spain). The items of the CSI were adapted for newborn care. Content validity was measured by five experts, calculating the index of agreement (Aiken's V). Criterion validity was assessed by correlations with scores of other tools that measure constructs related to burden (Edinburgh Postpartum Depression Scale, State-Trait Anxiety Questionnaire, SOC-13 and Duke-UNC-11). Construct validity was determined by the known-groups method. Internal consistency was measured using Cronbach's Alpha, and stability was analysed using the intraclass correlation coefficient (ICC).

RESULTS

Regarding content validity, an Aiken's V of 1.00 (p = 0.032) was obtained. Regarding criterion validity, the correlation analyses showed statistically significant coefficients between the scores of the questionnaire and those of the sense of coherence (r = -0.447, p < 0.001), depressive symptoms (r = 0.429, p < 0.001), social support (rho = -0.379, p < 0.001) and anxiety symptoms (r = 0.532, p < 0.001). The known-groups method showed statistically significant differences in the mean of subjective burden between the groups (depressive symptoms, anxiety symptoms, sense of coherence and social support). The total scale obtained a Cronbach's alpha value of 0.710. The ICC was 0.979.

CONCLUSIONS

The adapted CSI is a valid and reliable screening tool for the subjective burden in women during the puerperium. The adapted CSI can play an important role as a guide to detect the subjective burden in women during the puerperium.

The Quality of Carer-Patient Relationship Scale: Adaptation and Validation into Portuguese

BACKGROUND

This study aimed to translate and adapt the Quality of the Carer-Patient Relationship (QCPR) scale into Portuguese and analyse both its psychometric properties and correlation with sociodemographic and clinical variables.

METHODS

Phase (1) Translate and culturally adapt the scale. Phase (2) Assess the scale's confirmatory factorial analysis, internal consistency, construct validity, and correlations.

RESULTS

The experts classified the overall quality of the translation as adequate. A total of 53 dyads (cared-for person and carer) were assessed. In both versions, measures of central tendency and symmetry were also adequate, and the two factors under investigation had appropriate reliability, although in the conflict/critical factor, this was more fragile. Cronbach's alpha values were 0.89 for the cared-for person version and 0.91 for the carer version.

CONCLUSIONS

The QCPR scale showed satisfactory to good values of reliability. The assessment is essential to guarantee structured interventions by health professionals, since the quality of the dyads' relationship seems to influence both older adults' quality of life and carers' health status. This study is a significant contribution to the introduction of the QCPR scale in the Portuguese clinical and scientific culture but also an opportunity to increase its use internationally.

Positive aspects of care in informal caregivers of community-dwelling dementia patients

WHAT IS KNOWN ON THE SUBJECT?: Positive aspects of care are considered an essential part of caregiving research. They have been related to a wide range of dimensions of the caregiving circumstances, but there are few valid, reliable and brief measures to assess them. One of the most frequently used internationally is the Positive Aspects of Caregiving (PAC) scale, whose psychometric properties have received little attention. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The present study analyses the psychometric properties of the Portuguese version of the PAC scale in a sample of informal caregivers of someone with dementia and further explores the association of different factors (e.g. caregiver health, sociodemographic variables) with the PAC. The Portuguese version of PAC scale presented good psychometric characteristics, and the factor analysis revealed the presence of two factors: affirming self and enriching life. Our study also verified that higher levels of PAC are more likely to be associated with better caregiver health perception, lower levels of psychological distress and burden, the care recipient's older age, providing care to more than one care recipient, not receiving social support services and not considering institutionalizing the care recipient. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Findings from this study can assist professionals, including mental health nurses, to develop and implement effective interventions that help dementia caregivers to maintain their emotional health by identifying and focusing specific positive aspects of care. The study stresses the Portuguese version of the PAC scale as a reliable and valid measure for practice. ABSTRACT: Introduction Positive aspects of care refer to the psychosocial benefits of caregiving. The Positive Aspects of Caregiving (PAC) scale is one of the instruments most frequently used internationally, but its psychometric properties and correlates within the caregiving experience have received limited attention. Aim To examine the factorial structure of the Portuguese version of PAC scale and to analyse background and contextual factors that are more likely to be associated with higher levels of PAC. Method The PAC scale, a sociodemographic questionnaire and measures assessing burden and physical and mental health were administered to 204 informal caregivers of dementia patients. Results Exploratory factor analysis revealed a two-factor structure; internal consistency was adequate. Higher scores were negatively correlated with caregiver burden and distress. Better health perception, care recipient's older age, providing care to more than one care recipient and overall self-reliance were correlated with higher levels of PAC. Discussion The PAC scale was found to be a reliable and valid measure. Dementia caregiving circumstances and caregivers' and care receivers' characteristics play an important role for the presence of PAC, but relate distinctively with its dimensions. Implications for Practice Findings can help mental health nurses to recognize distinctive relations between PAC and caregiving variables.
