Mediation effect of depressive symptoms in the relationship between perceived control and wellbeing in patients with heart failure and their partners

Perceived control attitude among heart failure patients in Oman: a multicenter study

Heart failure (HF) is a global epidemic with a prevalence of over 64.3 million cases worldwide. Several factors account for the increase in the prevalence of HF. The most significant factor is the growing population of older adults. Other factors include improved treatment and survival after myocardial infarction, poorly controlled hypertension (HTN), and diabetes mellitus (DM). As a modifiable construct, perceived control can be improved to promote healthier lifestyle choices, such as self-care, and consequently better health outcomes. A person's perception of control is their conviction that they have the power to deal with adverse circumstances, like receiving an HF diagnosis, and produce favorable results, such as an improvement in symptom status. The objective of this study was to evaluate the factors influencing perceived control attitudes among patients with heart failure in Oman. In this sample of HF patients (N = 180), the mean perceived control attitude was 16.97 ± 2.25. Certain factors had higher effects than others. For example, females (p = 0.006), old age (p < 0.001), those who smoke (p < 0.001), current health compared to one year back (p < 0.001), higher ejection fraction (p = 0.008), and comorbidities (p = 0.026) have significant relationships with perceived control attitude. The perceived control attitude in this sample was found to be adequate. Female gender, old age, smoking, current health, higher EF, and comorbidities were the associated factors of a perceived control attitude. Thus, interventions targeting attitudes, barriers, and social support may improve perceived control. Clinicians should assess and manage perceived control to maintain or improve quality of life.

Contribution of informal caregivers to self-care in individuals with heart failure

OBJECTIVES

to evaluate the contribution of informal caregivers to the self-care of individuals with heart failure.

METHODS

a cross-sectional study was conducted with 87 caregivers from March to October 2022 in the city of João Pessoa/PB. The caregivers' contribution was assessed using the Caregiver Contribution to Self-Care of Heart Failure Index instrument. Scores ≥ 70 points indicate adequate contribution. Data were analyzed using descriptive statistics and Spearman's correlation.

RESULTS

the sample consisted of 81.6% female caregivers. Median scores obtained for the self-care contribution scales were: 63.3 for maintenance; 55.5 for management; and 66.6 for confidence. Caregivers never or rarely recommended monitoring body weight, regular physical exercise, extra use of diuretics, and fluid restriction.

CONCLUSIONS

informal caregivers showed inadequate contribution in the areas of maintenance, management, and confidence in self-care of individuals with heart failure.

Associations of multidimensional fatigue with the physical, psychological, and situational factors in outpatients with heart failure: a cross-sectional study

AIMS

Fatigue, a distressing symptom in patients with heart failure (HF), is associated with progress and health outcomes. Fatigue has been identified as having multidimensions, but a few studies have used a multidimensional fatigue scale. Many factors related to HF, including physical, psychological, and situational factors, may impact fatigue. However, there is limited knowledge about how these HF-related factors are associated with multidimensional fatigue in outpatients with HF in Japan. The aim of this study was to identify HF-related factors [physical; clinical characteristics, New York Heart Association (NYHA) functional class and physical function, psychological; depressive symptoms and anxiety, situational; health literacy and perceived control] associated with the five dimensions of fatigue in outpatients with HF.

METHODS AND RESULTS

Outpatients with HF (N = 165, mean age = 69.5 years, 78.8% male) completed the survey and physical assessment of gait speed. Fatigue was assessed using five dimensions of the Multidimensional Fatigue Inventory-20. Multiple linear regression analysis was conducted for each dimension of fatigue. General fatigue was predicted by age, NYHA, and perceived control. Physical fatigue was predicted by NYHA, depressive symptoms, and perceived control. Reduced activity was predicted by NYHA, gait speed, depressive symptoms, communicative health literacy, and critical health literacy. The reduced motivation was predicted by depressive symptoms and perceived control. Mental fatigue was predicted by depressive symptoms.

CONCLUSION

Different factors were significantly associated with each fatigue dimension. Further research is needed to alleviate fatigue in patients with HF.

Control Attitudes Scale-Revised-Brazilian Version

BACKGROUND

Heart failure demands self-care skills and behaviors that can be negatively impacted by a low level of perceived control (PC), a belief about having the necessary resources to deal with negative events. Having valid and reliable instruments to measure PC is important to support interventions that improve self-care and related outcomes. The Control Attitudes Scale-Revised (CAS-R) was developed in the United States to measure PC in cardiac conditions. In Brazil, there are no instruments available to measure this construct.

OBJECTIVE

The aims of this study were to translate and adapt the CAS-R to the Brazilian population and to assess the content validity of the adapted version.

METHODS

The CAS-R was translated, back-translated, and assessed by an expert committee for linguistic equivalences. An agreement > 80% was considered adequate. Content validity (clarity, theoretical relevance, and practical pertinence) was assessed by both an expert professional panel (n = 6-8) and a panel of patients with heart failure (n = 40). A content validity coefficient > 0.70 was considered acceptable.

RESULTS

The translations to Brazilian Portuguese were considered consistent with the original CAS-R. In the third round of linguistic equivalence assessment, all items achieved acceptable agreement, except for 2 items. After modifications to the instrument to achieve adequate equivalences, the adapted version had a final content validity coefficient of 0.93. Most patients were able to understand the instrument.

CONCLUSIONS

The CAS-R-Brazilian version is equivalent to the original CAS-R and has satisfactory evidence of content validity. Additional psychometric testing will be performed to allow for the assessment of PC in individuals with heart failure in Brazil.

The Role of Self-Care Activities (SASS-14) in Depression (PHQ-9): Evidence From Slovakia During the COVID-19 Pandemic

In the ongoing situation, when the world is dominated by coronavirus disease 2019 (COVID-19), the development of self-care programs appears to be insufficient, while their role in mental health may be crucial. The aim of the study was to evaluate the associations between self-care activities and depression in the general Slovak population, but also in its individual gender and age categories. This was achieved by validating the self-care screening instrument, assessing differences, and evaluating the associations using quantile regression analysis. The final research sample consisted of 806 participants [males: 314 (39%), females: 492 (61%)] and data were collected through an online questionnaire from February 12, 2021 to February 23, 2021. Patient Health Questionnaire (PHQ-9) for depression (α = 0.89) and Self-Care Activities Screening Scale (SASS-14) [health consciousness (HC) (α = 0.82), nutrition and physical activity (NPA) (α = 0.75), sleep quality (SLP) (α = 0.82), and interpersonal and intrapersonal coping strategies (IICS) (α = 0.58)] were used as screening measures. Mild depressive symptoms were found in 229 participants (28.41%), moderate depressive symptoms in 154 participants (19.11%), moderately severe depressive symptoms in 60 participants (7.44%) and severe depressive symptoms in 43 participants (5.33%). The main findings revealed the fact that individual self-care activities were associated with depression. This supported the idea that well-practiced self-care activities should be an immediate part of an individual's life in order to reduce depressive symptoms. Sleep quality played an important role, while HC indicated the need for increased attention. Other dimensions of self-care also showed significant results that should not be overlooked. In terms of depression, females and younger individuals need targeted interventions. The supportive educational intervention developed based on the self-care theory can help manage and maintain mental health during a stressful period, such as the COVID-19 pandemic. Health policy leaders should focus on health-promoting preventive self-care interventions, as the demand for them increases even more during the pandemic.

Effectiveness of nurse-led program on mental health status and quality of life in patients with chronic heart failure

Current study was to evaluate the effectiveness of nurse-led program in improving mental health status (MHS) and quality of life (QOL) in chronic heart failure (CHF) patients after an acute exacerbation. CHF patients were enrolled after informed consent was obtained and were assigned into the control and treatment group. Patients in the control group received standard care. In the treatment group, patients received standard care plus telehealth intervention including inquiring patients medical condition, providing feedbacks, counseling patients, and having positive and emotional talk with patients. At the third and sixth month after discharge, participants were called by registered nurses to assess Mental Health Inventory-5 (MHI-5) and Kansas City Cardiomyopathy Questionnaire (KCCQ) scores. Compared to the treatment group, patients in the control group were less likely to have educational attainment ≥ high school degree and have a married status, but were more likely to have diabetes. No significant differences in MHI-5 (68.5 ± 12.7 vs 66.9 ± 10.4) and KCCQ (70.6 ± 12.2 vs 68.7 ± 10.9) scores at baseline between the control and treatment groups were observed. There were significantly differences in MHI-5 (72.7 ± 15.6 vs 65.2 ± 11.4) and KCCQ score (74.2 ± 14.9 vs 66.4 ± 12.1) at 3 months follow-up between control and treatment groups. Nonetheless, at 6 months follow-up, although MHI-5 and KCCQ scores remained higher in the treatment group, there were no statistically significant differences (MHI-5: 65.4 ± 12.8 vs 61.4 ± 10.0; KCCQ: 65.1 ± 12.3 vs 61.9 ± 10.3). After multivariate regression analysis, not receiving nurse-led program were significantly associated with reduced MHI-5 (odds ratio [OR] 1.25% and 95% confidence interval [CI]: 1.14-1.60) and KCCQ (OR: 1.20% and 95% CI:1.11-1.54) scores. Nurse-led program is helpful to improve MHS and QOL in CHF patients after an acute exacerbation. However, these achievements are attenuated quickly after the nurse-led intervention discontinuation.

Linguistic and Psychometric Validation of the Chinese Version of the Control Attitudes Scale-Revised in Patients With Chronic Heart Failure

BACKGROUND

The concept of perceived control reflects the belief that one has resources needed to cope with negative events and the ability to positively influence consequences of those negative events. In patients with heart failure, perceived control is associated with a variety of health outcomes. Perceived control is commonly measured using the Control Attitudes Scale-Revised (CASR). There is no Chinese version of the CAS-R (CCAS-R).

OBJECTIVE

The purpose of this article was to perform linguistic validation and psychometric evaluation of the CCAS-R.

METHODS

The CAS-R was translated into Chinese according to Brislin's model. Then, a multicenter observational study was performed. Floor and ceiling effects, internal consistency, structural validity, and hypothesis testing were all assessed for psychometric validation of the CCAS-R.

RESULTS

A total of 227 patients with chronic heart failure were included. There were no ceiling or floor effects detected. Cronbach α was 0.94, indicating a high reliability. The results of the confirmatory factor analysis showed that the 1-factor structure as proposed by the original CAS-R fits the data well. The results of the principal component analysis suggested that the 1-factor structure was optimal as well, accounting for 71.6% of the total variance. The a priori hypothesis was supported by a statistically significant correlation between the CCAS-R and 3 theoretically related variables.

CONCLUSION

We developed a semantically equivalent version of the CAS-R in Chinese. The evaluation of the instruments' psychometric properties demonstrated that the CCAS-R has good reliability and validity for use in Chinese patients with chronic heart failure.

Understanding the family care dyad: A comparison of two multilevel models

Although there has been increasing attention on a dyadic perspective of illness, contemporary dyadic research methods are still rarely utilized in cardiovascular disease. The focus of this paper is to describe the advantages of two types of multilevel dyadic models (the matched pairs model and the lesser known incongruence model). Data exemplars in a sample of heart failure family dyads are used to illustrate the distinct advantages of these two related multilevel dyadic models with particular emphasis on alignment with research questions. The more commonly known matched pairs model examines separate outcomes for each member of the dyad, controlling for the interdependent nature of the data. By re-parameterizing this model into a univariate dyadic outcomes model, researchers can address distinct, and sometimes more appropriate, research questions (e.g. incongruent appraisals of the illness experience). This paper promotes greater application of these methods in cardiovascular research to further understanding of the dyadic experience and more appropriately target interventions.

Evaluating emotional distress and health-related quality of life in patients with heart failure and their family caregivers: Testing dyadic dynamics using the Actor-Partner Interdependence Model

PURPOSE

1) To compare levels of emotional symptoms and health-related quality of life between patients with heart failure and their family caregivers; and 2) to examine whether patients' and caregivers' emotional symptoms were associated with their own, as well as their partner's health-related quality of life.

METHOD

In this cross-sectional study, 41 patients-caregiver dyads (78% male patients, aged 68.6 years; and 83% female caregivers, aged 65.8 years) completed all nine dimensions of the Brief Symptom Inventory and the Minnesota Living with Heart failure Questionnaire. Dyadic data were analysed for 6 sub-scales of the Brief Symptom Inventory, using the Actor-Partner Interdependence Model.

RESULTS

There were no statistically significant differences in emotional symptoms and health-related quality of life between patients with heart failure and their caregivers. Patients' and caregivers' emotional symptoms were associated with their own health-related quality of life. Caregivers' anxiety, phobic anxiety, obsession-compulsion, depression and hostility negatively influenced their partner's (i.e. the patient's) health-related quality of life. There were no partner effects of patients' emotional symptoms on the health-related quality of life of caregivers.

CONCLUSIONS

The results of this study suggest that patients may be particularly vulnerable to the emotional distress, i.e. thoughts, impulses and actions of their caregivers. It may be possible to improve patients' health-related quality of life by targeting specific detrimental emotional symptoms of caregivers.
