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%.

Predictors of health-related quality of life after coronary artery bypass graft surgery

Health-related quality of life (HRQOL) is a multifactorial concept in assessing physical and mental health. This study was performed to evaluate the HRQOL of patients undergoing coronary artery bypass graft (CABG) surgery and the predictors of HRQOL in patients until 1 year after surgery. This cross-sectional study included 110 consecutive patients who underwent elective CABG in a medical center in South Korea. The Short-Form Health Survey, cardiac symptom survey, cardiac self-efficacy, and the Interpersonal Support Evaluation List-12 were used to measure the HRQOL, symptom experience, self-efficacy, and social support, respectively. The regression model explained 42% of the variance in the participants' physical HRQOL. The predictors of the physical HRQOL include the presence of a spouse, post-CABG duration, symptom experience, and self-efficacy. The regression model explained 36% of the variance in the participants' mental HRQOL. The predictors of the mental HRQOL included perceived health status, self-efficacy, and social support. The predictive factors for HRQOL after CABG were the presence of a spouse, post-CABG duration, symptom experience, self-efficacy, and social support. Furthermore, a suitable program and nursing interventions could be implemented to improve the HRQOL of post-CABG patients.

The multiple mediating effects of social connectedness and self-care confidence on the relationship between subjective social status and emotional well-being in patients with heart failure: a cross-sectional study

BACKGROUND

Previous studies have shown that subjective social status (SSS) was positively associated with well-being in various populations. However, little is known about the relationship considering the underlying mechanism in patients with heart failure (HF).

AIMS

The aim was to study the effects of social connectedness and self-care confidence on the relationship between SSS and well-being in patients with HF according to the Reserve Capacity Model.

METHODS AND RESULTS

We recruited 296 patients from a general hospital using convenience sampling. SSS, social connectedness, self-care confidence, and well-being were assessed using self-reported questionnaires. A multiple mediation model was examined using the PROCESS macro in SPSS.Higher levels of SSS (r = 0.18, P < 0.01), social connectedness (r = 0.21, P < 0.01), and self-care confidence (r = 0.20, P < 0.01) were positively correlated with better emotional well-being, but not with physical well-being. The multiple mediation analysis revealed that the relationship between SSS and emotional well-being was mediated by social connectedness (effect: 0.061, 95% CI [0.014, 0.148]) and self-care confidence (effect: 0.110, 95% CI [0.006, 0.249]) separately, and together in serial (effect: 0.008, 95% CI [0.001, 0.028]).

CONCLUSIONS

Social connectedness and self-care confidence are multiple mediators of the relationship between SSS and emotional well-being. Interventions targeting to strengthening social connectedness and self-care confidence may improve emotional well-being directly. In addition, emotional well-being may be improved by enhancing SSS indirectly in patients with HF.

Effects of person-centred care via telephone on self-efficacy in patients with chronic obstructive pulmonary disease: Subgroup analysis of a randomized controlled trial

AIM

To evaluate the effects of PCC in the form of structured telephone support on self-reported cardiac self-efficacy in patients with COPD.

METHODS

We enrolled 105 patients, aged ≥50 years, admitted to hospital and diagnosed with COPD from January 2015 to November 2016. The patients received usual care or PCC via telephone added to usual care. The Swedish Cardiac Self-Efficacy Scale comprising three dimensions (control symptoms, control illness and maintain functioning) was used as outcome measure. Data was collected at baseline, and at 3- and 6-month follow-ups.

RESULTS

At both the 3- and 6-month follow-ups, the intervention group improved significantly more than the control group in the control illness dimension (p = .012 and p = .032, respectively). No differences were found in the other two dimensions.

CONCLUSIONS

PCC in the form of structured telephone support increases patients' confidence in managing their illness and may be a feasible strategy to support patients in their homes.

Positive effects of resilience and self-efficacy on World Health Organization Quality of Life Instrument score among caregivers of stroke inpatients in China

AIM

Stroke is one of the major health challenges affecting life expectancy and quality of life around the world. However, there is limited reporting on the status of some caregivers, including Chinese caregivers of stroke inpatients. Limited information is available on evaluations using the World Health Organization Quality of Life Instrument (WHOQOL) and the effects of resilience and self-efficacy on WHOQOL score. Therefore, we conducted research to assess the role of resilience on the WHOQOL and to investigate the role of self-efficacy as a mediator between resilience and WHOQOL score among Chinese caregivers of stroke inpatients.

METHODS

This cross-sectional study to gather data from north-east and south-east China was conducted from June 2019 to October 2019. Over 380 caregivers of stroke inpatients at two general public hospitals were interviewed face-to-face. About 305 caregivers (80.26%) completed the questionnaire, which included the Ego Resilience Scale, the General Self-Efficacy Scale, and the brief version of the WHOQOL and asked about demographic characteristics. This study also examined factors associated with WHOQOL score and used linear regression analysis and structure equation modelling to construct direct and indirect models, respectively.

RESULTS

After adjustment for demographic characteristics, both resilience and self-efficacy were positively associated with all WHOQOL domains. Structure equation modelling revealed that self-efficacy mediated the relationship between resilience and WHOQOL score among caregivers of stroke inpatients.

CONCLUSION

Chinese caregivers of stroke inpatients exhibited good social health but poor physical, psychological, and environmental health. It is necessary for promoting resilience and improving WHOQOL score through the mediating effect of self-efficacy. These results suggest that interventions in health care focused on both enhancing resilience and providing self-efficacy training could effectively improve WHOQOL score.
