A Structural Equation Model of Gratitude, Self-efficacy, and Medication Adherence in Patients With Stage B Heart Failure

A Longitudinal Study of Adherence among Cystic Fibrosis Patients: Associations with Gratitude Over the Course of One Year

BACKGROUND

Daily airway clearance therapy (ACT) is a critical aspect of treatment in cystic fibrosis (CF), but poor adherence is a prominent concern. Identifying factors that might enhance or diminish adherence is a priority for treatment centers. Gratitude, a generalized tendency to notice and appreciate positive facets of experience, is a psychosocial resource that has commanded growing research interest. This longitudinal study examined whether gratitude at baseline was associated with ongoing or persistent ACT adherence over the course of a year.

METHODS

Trait gratitude was evaluated at baseline using a validated measure, among adults receiving care at a regional CF treatment center. Self-reported adherence to ACT was assessed at baseline, 6 months, and 12 months using the Cystic Fibrosis Treatment Questionnaire. Average age of participants was 27.2 years, 45.5% were women, and 19.7% had severe disease.

RESULTS

In multivariable logistic regression models that accounted for disease severity (Forced Expiratory Volume1% predicted) and other clinical and demographic variables, individuals with higher baseline gratitude were significantly more likely to demonstrate persistent adherence over the course of the year. Gratitude remained predictive after additionally adjusting for other well-known psychosocial resource variables (social support and emotional well-being).

CONCLUSION

This is among the first demonstrations that gratitude is associated with persistent self-reported adherence to treatment over time. Findings suggest that gratitude may be important psychosocial resource for adults with CF, as they contend with complex, highly burdensome treatment regimens. Further research is warranted to examine these relationships and their impact on downstream health outcomes.

Cognitive predictors and decision-making in the experience of coronary syndrome symptoms

OBJECTIVE

To determine the predictive value of Cognitive Assessment, Symptom Severity, Personal Control and Self-Efficacy on decision making in the experience of Acute Coronary Syndrome symptoms.

METHOD

Quantitative study of cross-sectional analytical design, a probabilistic sampling was carried out for 256 participants diagnosed with coronary syndrome in three health institutions. The effects between the independent variables Cognitive Assessment, Symptom Severity, Personal Control, Self-Efficacy and the dependent Decision-Making were analyzed. Using inferential statistics, a Generalized Linear Regression Model was carried out, which allowed establishing the causal relationships between the variables.

RESULTS

Two predictive models were obtained between decision making and cognitive evaluation, in which personal control, severity of symptoms, sex and context were significant. Self-efficacy was not reported as a predictor variable. The values ​​of the independent variables showed a behavior directly proportional to the Decision Making score.

CONCLUSION

A verification of the conceptual model for the management of symptoms was carried out.

A predictive model for medication adherence in older adults with heart failure

AIMS

Although many studies have examined the predictors of medication adherence (MA), further empirical research is required to clarify the best model for predicting MA for older adults with heart failure (HF). Thus, we hypothesized a model in which information (knowledge), motivation (social support and depressive symptoms), and behavioural skills (barriers to self-efficacy) would be associated with MA in patients with HF.

METHODS AND RESULTS

Using a cross-sectional survey, 153 adults aged ≥ 65 years taking medication for HF were recruited from a university hospital in Korea. Data were collected based on the information-motivation-behavioural skills (IMB) model constructs and MA. In the hypothesized path model, self-efficacy was directly related to MA (β = -0.335, P = 0.006), whereas social support was indirectly related to MA through self-efficacy (β = -0.078, P = 0.027). Depressive symptoms were directly related to MA (β = 0.359, P = 0.004) and indirectly related to MA through self-efficacy (β = 0.141, P = 0.004). The hypothesized MA model showed a good fit for the data. Knowledge, social support, and depressive symptoms accounted for 44.3% of the variance in self-efficacy (P = 0.004). Left ventricular ejection fraction, knowledge, social support, depressive symptoms, and self-efficacy explained 64.4% of the variance in MA (P = 0.004).

CONCLUSION

These results confirmed the IMB model's suitability for predicting MA in older adults with HF. These findings may guide and inform intervention programmes designed to alleviate depressive symptoms in older adults with HF and enhance their HF knowledge, social support, and self-efficacy, with the ultimate goal of improving their MA.

Mediating effects of general self-efficacy on social support and quality of life in patients after surgical aortic valve replacement

AIM

To explore whether general self-efficacy can mediate the relationship between social support and quality of life in patients after surgical aortic valve replacement.

DESIGN

A cross-sectional design.

METHODS

The final analysis included 283 patients who underwent surgical aortic valve replacement from May 2021 to September 2021. They completed a set of questionnaires, including the Chinese version of the General Self-Efficacy Scale, the Chinese Questionnaire of Quality of life in Patients with Cardiovascular Diseases and the Social Support Rating Scale. The PROCESS Macro in SPSS was used to analyse the mediating effect.

RESULTS

Quality of life and all of its dimensions were significantly related to social support and general self-efficacy. A significant indirect effect of social support existed through general self-efficacy in relation to quality of life with the mediation effect ratio of 32.82%.

The impact of gratitude interventions on patients with cardiovascular disease: a systematic review

Positive psychological factors play a pivotal role in improving cardiovascular outcomes. Gratitude interventions are among the most effective positive psychological interventions, with potential clinical applications in cardiology practice. To better understand the potential clinical effects of gratitude interventions in cardiovascular disease, four databases (Web of Science, Scopus, PubMed, and PsycArticles) were searched from 2005 to 2023 for relevant studies. Randomized controlled trials of gratitude interventions as the intervention and that reported physiological or psychosocial outcomes were eligible for inclusion. In total, 19 studies were identified, reporting results from 2951 participants from 19 to 71 years old from both healthy populations and those with clinical diagnoses. The studies showed that gratitude not only promotes mental health and adherence to healthy behaviors but also improves cardiovascular outcomes. Gratitude may have a positive impact on biomarkers of cardiovascular disease risk, especially asymptomatic heart failure, cardiovascular function, and autonomic nervous system activity.

Association between medication literacy and medication adherence and the mediating effect of self-efficacy in older people with multimorbidity

BACKGROUND

Multimorbidity has a significant impact on public health and primary care. Medication adherence is recognized as the most effective measure for managing and preventing multimorbidity. Studies have shown that medication literacy has a positive effect on medication adherence in patients with multimorbidity. However, limited knowledge exists regarding the underlying mechanisms of this relationship in older adults with multimorbidity. Therefore, the aim of this study was to investigate the mediating role of self-efficacy in the association between medication literacy and medication adherence in this population.

METHODS

This study employed a cross-sectional design and convenience sampling method to survey older patients with multimorbidity in six communities in Zhengzhou, China, from July 12, 2021, to December 15, 2021. Participants were assessed using a demographic questionnaire, the Chinese Version of the Medication Literacy Scale (C-MLS), the Self-Efficacy for Appropriate Medication Use Scale (SEAMS), and the Chinese Version of the Morisky Medication Adherence Scale-8 (C-MMAS-8). Data were analyzed using descriptive statistics, t-tests, one-way analysis of variance, Pearson correlation analysis, and mediation analysis.

RESULTS

A total of 350 elderly patients met the inclusion criteria, and 328 valid questionnaires were collected. The mean age of the participants was 74.90 ± 7.37 years, with a slightly higher proportion of males (55.8%) than females (44.2%). The mean score for medication adherence was 4.85 ± 1.57, indicating poor medication adherence among the participants. Medication adherence scores varied significantly among participants of different ages, education levels, employment statuses and kinds of medication (p < 0.01). Scores for medication literacy and self-efficacy showed a significant positive correlation with medication adherence scores (all p < 0.001). The standardized coefficient for the total effect and direct effect of medication literacy on medication adherence was 0.268 (95% CI: 0.201, 0.335) and 0.187 (95% CI: 0.123, 0.252), respectively. After introducing self-efficacy into the model, the standardized coefficient for the indirect effect was 0.081 (95% CI: 0.049, 0.120), indicating that self-efficacy partially mediated the relationship between medication literacy and medication adherence, accounting for 30.22% of the total effect.

CONCLUSION

This study might suggest that medication literacy indirectly affected medication adherence in older people with multimorbidity through self-efficacy. Health care providers should be aware of the importance of improving medication literacy and implement strategies aimed at increasing self-efficacy to achieve the goal of improving medication adherence in older adults with multimorbidity.

Remote motivational interviewing to improve patient self-care and caregiver contribution to self-care in heart failure (REMOTIVATE-HF): Rationale, design, and methodology for a multicentre randomized controlled trial

In patients with heart failure (HF), self-care, and caregiver contribution to self-care (i.e., the daily management of the disease by patients and caregivers) are essential for improving patient outcomes. However, patients and caregivers are often inadequate in their self-care and contribution to self-care, respectively, and struggle to perform related tasks. Face-to-face motivational interviewing (MI) effectively improves self-care and caregiver contribution to self-care, but the evidence on remote MI is scarce and inconclusive. The aims of this randomized controlled trial will be to evaluate whether remote MI performed via video call in patients with HF: (1) is effective at improving self-care maintenance in patients (primary outcome); (2) is effective for the following secondary outcomes: (a) for patients: self-care management, self-care monitoring, and self-efficacy; HF symptoms; generic and disease-specific quality of life; anxiety and depression; use of healthcare services; and mortality; and (b) for caregivers: contribution to self-care, self-efficacy, and preparedness. We will conduct a two-arm randomized controlled trial. We will enroll and randomize 432 dyads (patients and their informal caregivers) in Arm 1, in which patients and caregivers will receive MI or, in Arm 2, standard care. MI will be delivered seven times over 12 months. Outcomes will be assessed at baseline and 3 (primary outcome), 6, 9, and 12 months from enrollment. This trial will demonstrate whether an inexpensive and easily deliverable intervention can improve important HF outcomes. With the restrictions on in-person healthcare professional interventions imposed by the COVID-19 pandemic, it is essential to evaluate whether MI is also effective remotely.

Effects of a multidisciplinary management program on symptom burden and medication adherence in heart failure patients with comorbidities: A randomized controlled trial

BACKGROUND

Comorbidities in heart failure (HF) are a complex clinical challenge. There is little data on the benefits of multidisciplinary postdischarge management programs in such patients. This study aimed to examine the effects of a multidisciplinary management program (MMP) on symptom burden and medication adherence in HF patients with comorbidities.

METHODS

In this clinical trial study, 94 HF patients with comorbidities were assigned to intervention (n = 47) and control (n = 47) groups by the stratified-random method. The intervention group underwent MMP supervised by a nurse for two months after discharge, including multi-professional visits, telephone follow-ups, and an educational booklet. Medication adherence and symptom burden were assessed using Morisky Medication Adherence Scale (MMAS) and Edmonton Symptom Assessment Scale (ESAS), respectively, on three occasions: Before discharge, six weeks, and eight weeks after discharge.

RESULTS

Both groups almost matched at the baseline, and the most frequent comorbidities included myocardial infarction (MI), hypertension, peptic ulcer, and depression, respectively. The interactive effect of time in groups showed that mean changes in total scores of symptom burden and medication adherence were significantly different (P < 0.001) at other time points. A significant increase in medication adherence (P < 0.001) and a significant reduction in the burden of all symptoms were observed in the intervention group compared to the control group from Time 1 to Time 3.

CONCLUSIONS

The MMP (targeting comorbidity) is a promising strategy for managing symptoms and medication adherence in HF patients with comorbidities.

The Situation-Specific Theory of Heart Failure Self-care: An Update on the Problem, Person, and Environmental Factors Influencing Heart Failure Self-care

Many studies of heart failure (HF) self-care have been conducted since the last update of the situation-specific theory of HF self-care.

OBJECTIVE

The aim of this study was to describe the manner in which characteristics of the problem, person, and environment interact to influence decisions about self-care made by adults with chronic HF.

METHODS

This study is a theoretical update. Literature on the influence of the problem, person, and environment on HF self-care is summarized.

RESULTS

Consistent with naturalistic decision making, the interaction of the problem, person, and environment creates a situation in which a self-care decision is needed. Problem factors influencing decisions about HF self-care include specific conditions such as cognitive impairment, diabetes mellitus, sleep disorders, depression, and symptoms. Comorbid conditions make HF self-care difficult for a variety of reasons. Person factors influencing HF self-care include age, knowledge, skill, health literacy, attitudes, perceived control, values, social norms, cultural beliefs, habits, motivation, activation, self-efficacy, and coping. Environmental factors include weather, crime, violence, access to the Internet, the built environment, social support, and public policy.

CONCLUSIONS

A robust body of knowledge has accumulated on the person-related factors influencing HF self-care. More research on the contribution of problem-related factors to HF self-care is needed because very few people have only HF and no other chronic conditions. The research on environment-related factors is particularly sparse. Seven new propositions are included in this update. We strongly encourage investigators to consider the interactions of problem, person, and environmental factors affecting self-care decisions in future studies.

Race Moderates the Relationship Between Perceived Social Support and Self-care Confidence in Patients With Heart Failure

BACKGROUND

African Americans are at the highest risk of developing heart failure (HF) compared with other races and are hospitalized at 7 to 8 times the rate of Whites. Poor overall self-care, low self-care confidence, and lower levels of perceived social support are factors related to increased risk for hospitalizations in HF. Yet, limited evidence is available regarding the factors that may differentially impact self-care confidence by race in patients with HF.

OBJECTIVE

The aim of this study was to examine to what extent race moderates the relationship between perceived social support and self-care confidence.

METHOD

This is a secondary analysis of cross-sectional data from African American and White patients with HF in North America (n = 429). Patients completed the Multidimensional Scale of Perceived Social Support and the Self-Care Confidence Scale of the Self-Care of Heart Failure Index. A moderation analysis was conducted using hierarchal linear regression.

RESULTS

Sample mean age was 60.8 ± 11.5 years, 22.4% were African American, and 54.7% were in New York Heart Association class I or II. Moderation analyses yielded a significant interaction of perceived social support and race, showing White patients, not African Americans, have significantly different self-care confidence scores depending on level of social support: White, b = 0.224, 95% confidence interval [0.046-0.094], t = 5.65, and P < .001; African American, b = -0.776, 95% confidence interval [-0.049 to 0.060], t = 0.212, and P = .832.

CONCLUSIONS

Our findings show a variable effect of perceived social support on self-care confidence as a function of race, suggesting the need for further research to develop and test interventions tailored to race and levels of social support in HF.

The Effect of Family Atmosphere on Chinese College Students' Pro-social Behavior: The Chained Mediation Role of Gratitude and Self-Efficacy

The current study aimed to explore how family atmosphere influenced pro-social behavior among Chinese college students and to explore the mediation roles of gratitude and self-efficacy. We recruited 800 Chinese college students, and the participation rate was 89% (712 participants, M = 19.26, SD = 1.23). Participants completed the family atmosphere scale, the pro-social tendencies measure, the gratitude questionnaire, and the general self-efficacy scale. Results indicated that (1) Family atmosphere, gratitude, self-efficacy, and pro-social behavior were positively correlated after controlling for the grade, gender, and age. (2) The family atmosphere affected pro-social behavior not only directly, but also indirectly through the partial mediating role of gratitude and self-efficacy. Moreover, gratitude and self-efficacy also played a full chained mediation role in the relationship between the family atmosphere and pro-social behavior of college students. Therefore, a supportive family atmosphere is conducive to promoting college students' gratitude and self-efficacy, in turn affecting their pro-social behavior.
