Complications after acute coronary syndrome are reduced by perceived control of cardiac illness

Studies on Pain Associated with Anxiety or Depression in the Last 10 Years: A Bibliometric Analysis

Background

The prevalence of pain comorbid and anxiety/depression in clinical observations has been high, and the number of related publications has increased in recent years. Nevertheless, few studies have used bibliometric methods to analyze the scientific research on comorbid pain and depression/anxiety. The aim of this study was to systematically examine the trends in global scientific research on comorbid pain and depression/anxiety from 2012 to 2022.

Methods

Papers published between 2012 and 2022 were identified in the Web of Science database. Publications that examined comorbid pain and depression/anxiety were included. The language was limited to English. CiteSpace, Excel and VOSviewer were used to analyze the volume of publications, countries, institutions, authors, cocited authors, and keywords.

Results

A total of 30,290 papers met the inclusion criteria of the study. Using CiteSpace, VOSviewer and Excel, the results showed that the United States (10,614 publications), Harvard University (1195 publications), and Jensen, Mark P. (77 publications) were the most productive country, institution, and author, respectively. The hotspots and frontiers were "relationship between depression and pain", "gender differences in pain and depression/anxiety domains", "study of specific pain types with depression/anxiety", "treatment of pain combined with anxiety/depression", and "effects of COVID-19 on patients with pain combined with depression/anxiety".

Conclusion

These findings indicate a growing interest in the field of comorbid pain and depression/anxiety. The research has been broad and deep, but there is still much room for growth. Furthermore, there is a need for more mature global collaborative networks as well as more high-quality research results in the future.

Quality of life as a mediating factor in the relationship between fatigue and perception of safety among critical care nurses in the United Arab Emirates

BACKGROUND

A scientific understanding of the relationships between intensive care unit nurses' well-being and patient safety will allow nurse managers, administrators, and policymakers to simultaneously manage crucial organisational goals of nurses' health and patient safety. Understanding predictors of fatigue among intensive care unit nurses may help to balance personal and organisational impacts (e.g., turnover intention, sick leave) and provide a way to positively influence their safety perception.

OBJECTIVE

The aim of this study was to explore the association between work fatigue and perception of patient safety among nurses working in critical care units and determine whether their quality of life levels mediated this relationship.

METHODS

This study used a cross-sectional correlational comparative design. Participants were a sample of 250 intensive care unit nurses recruited conveniently from three large hospitals in the United Arab Emirates. The self-reported questionnaire included the Nursing Quality of Life Scale, the Fatigue Severity Scale, and the Safety Attitudes Questionnaire (SAQ)-ICU version, as well as sociodemographic characteristics and work-related information.

RESULTS

Of the 250 participating nurses, 76.8 % reported low QoL. There was a statistically significant correlation between nurses' Quality of Life and fatigue levels (r = 0.234, P = 0.000). Overall, 52.8 % of the sample had high fatigue and 49.6 % had poor safety perception. Multiple regression analysis using the Baron and Kenny approach showed that QoL, marital status, gender, and work environment were predictors of nurses' perception of safety.

CONCLUSION

Intensive care unit nurses had high levels of fatigue and poor Quality of Life. High Quality of Life and a favourable work environment were independent predictors of good patient safety perception. Efforts should be directed to maximize staffing resources that positively impact patient safety. These findings are comparable with international studies, suggesting that these issues may be ubiquitous.

IMPLICATIONS FOR CLINICAL PRACTICE

Intensive care practitioners, managers and policymakers should adopt measures to modify intensive care nurses' exhausting working conditions and provide a supportive environment. these interventions might improve nurses' perception of patient safety and consequently prevent safety incidents.

Psychometric Evaluation of the Korean Version of Control Attitudes Scale-Revised

BACKGROUND

Heart failure (HF) is a chronic heart condition that requires patients to adapt to the disease and maintain a high degree of self-management. Patients with HF commonly feel loss of control, which has a negative effect on their compliance to self-care, health-related quality of life, and health outcomes. To promote self-care behavior and to develop healthy coping mechanisms, it is important to understand individual HF patients' perceived control, a self-generated belief that one has the ability to bring forth desired outcomes. Currently, there is no valid and reliable Korean instrument available in measuring perceived control among patients with HF.

OBJECTIVE

The objective of this study was to cross-culturally translate, adapt, and evaluate psychometric properties of the Korean version of Control Attitudes Scale-Revised (KCAS-R) in Korean patients with HF.

METHODS

The KCAS-R was developed using a translation/back-translation process and an examination of semantic and conceptual equivalence. Reliability was assessed using Cronbach α to determine internal consistency, and item-total and interitem correlations were assessed to test item homogeneity. The construct validity was examined using exploratory factor analysis, confirmatory factor analysis, and testing hypotheses for known associations with self-efficacy, self-care confidence, and self-care.

RESULTS

A convenience sample of 138 patients with HF were included for the psychometric testing of an 8-item KCAS-R. The Cronbach α for internal consistency was 0.835, and the item-total correlation was acceptable. The construct validity revealed a 2-factor structure accounting for 63.23% of the total variance. The KCAS-R was associated with higher levels of self-efficacy, self-care confidence, and self-care. In addition, patients with higher perceived control had less depression and anxiety compared with those with lower levels of perceived control.

CONCLUSION

This study provided support for the satisfactory reliability and validity of the 8-item KCAS-R in measuring perceived control in Korean patients with HF.

Relationship Between Resilience and Perceived Control After Acute Coronary Syndrome: A Prospective Study

BACKGROUND

Patients with acute coronary syndrome report poor health-related quality of life and decreased levels of perceived control. Perceived control is a person's belief that they can cope with negative events. Resilience is an adaptation that gives people the capacity to recover from difficult situations, and higher levels of resilience may impact recovery after an acute event.

OBJECTIVE

The aim of this study was to analyze the relationship between resilience, perceived control, and health outcomes of patients hospitalized with acute coronary syndrome within 6 months of discharge.

METHODS

Data were collected prospectively from adult patients hospitalized with acute coronary syndrome in 3 university hospitals in the Tokyo Metropolitan area, Japan. All data were collected between December 2015 and December 2019. The Sukemune-Hiew Resilience Test (part 1) was used to measure resilience, which includes 3 domains of social support, self-efficacy, and sociality. The Control Attitudes Scale-Revised was used to measure perceived control. Linear regression and path analysis were used to statistically analyze the relationship among variables.

RESULTS

Higher resilience, especially self-efficacy, was associated with higher perceived control during admission. Higher resilience, especially social support, during admission was associated with perceived control at 6 months after adjusting for income and education. Higher resilience during admission was associated with better perceived control at 3 months, which was associated with better health outcomes at 6 months. Higher income and lower depression were related to higher resilience.

CONCLUSIONS

Nurses should make sure patients with depression, low income, and low social support are connected with appropriate treatment and social support resources.

Factors related to perceived control and health-related quality of life of patients after acute coronary syndrome during admission and after discharge

Aim

To explore the relationship between demographic factors, acute coronary syndrome‐related factors, perceived control and health‐related quality of life during admission, 3 months and 6 months after discharge, in patients with acute coronary syndrome.

Methods

Participants were recruited for this longitudinal study after admission for acute coronary syndrome in three university hospitals in the Tokyo metropolitan area, Japan. Self‐administered questionnaires included demographic data, perceived control, health‐related quality of life, acute coronary syndrome symptoms, fatigue, depression and anxiety.

Results

Participants (N = 137) had an average age of 62.8 (SD 11.6) years and 80.3% were male. As a result of Path analysis, higher perceived control (β = 0.258, p = .001), lower anxiety (β = −0.226, p = .009) and lower fatigue (β = −0.231, p = .010), were significantly related to better health‐related quality of life (General health). Only annual income was significantly related to perceived control (β = 0.187, p = .029). Eighty‐two (59.9%) participants at 3 months and 54 (39.4%) participants at 6 months completed the questionnaires. Perceived control (F = 7.074, p = .001) and General health (χ² = 10.22, p = .006) significantly increased over the 6 months. Perceived control during admission was significantly related with health‐related quality of life at 3 months. Perceived control at 3 months was significantly related with health‐related quality of life at 6 months.

Conclusion

Perceived control was an important factor for health‐related quality of life of the Japanese patients with acute coronary syndrome. It is necessary to investigate whether nursing interventions to enhance perceived control lead to improvement of health‐related quality of life.

Perceived Control Predicts Symptom Status in Patients With Heart Failure

BACKGROUND

Symptom status is an important indicator of disease progression in patients with heart failure (HF). Perceived control is a target of most self-care interventions and is associated with better outcomes in HF; however, little is known about the relationship between perceived control and symptom status in patients with HF.

OBJECTIVE

The aims of this study were to (1) determine the relationship of perceived control to HF symptom status and (2) examine the associations of perceived control to self-care and of self-care to symptom status.

METHODS

A total of 115 patients with HF were included. Data on symptom status (Memorial Symptom Assessment Scale-HF), perceived control (Control Attitudes Scale-Revised), and self-care (Self-Care of Heart Failure Index) were collected. Other covariates included were age, gender, New York Heart Association class, comorbidity burden, and depressive symptoms. Multiple regression analyses were performed to analyze the data.

RESULTS

Lower perceived control predicted worse symptom status after controlling for covariates (P = .009). Other covariates predictive of worse symptom status were younger age, New York Heart Association class III/IV, and higher levels of depressive symptoms. Higher levels of perceived control were associated with better self-care (P = .044). Better self-care was associated with better symptom status (P = .038).

CONCLUSIONS

Lower levels of perceived control were independently associated with worse symptom status in patients with HF. Intervention strategies targeting perceived control should be tested to determine whether they could improve symptom status.

Validation of the Arabic Version of the Brief Symptom Inventory to Measure Anxiety in Patients With Acute Myocardial Infarction

BACKGROUND AND PURPOSE

Anxiety after acute myocardial infarction is well-known phenomenon. This study aimed to examine the psychometric properties of the Arabic version of the Brief Symptom Inventory to measure anxiety in this population.

METHODS

This was a prospective observational study among 460 patients. Patients answered the Brief Symptom Inventory and the Hospital Anxiety and Depression Scale to measure anxiety. Complications and other clinical variables abstracted from medical records.

RESULTS

Cronbach's α was .86, indicating adequate internal consistency. The item-total correlations and all interitem correlations were all acceptable. Anxiety was independent predictor for complication after acute myocardial infarction and higher in females supporting the construct validity.

CONCLUSION

Arabic version of the Brief Symptom Inventory is a valid and reliable instrument to measure anxiety after acute myocardial infarction.

Dyadic effects of type D personality and perceived control on health-related quality of life in cardiac arrest survivors and their spouses using the actor-partner interdependence model

BACKGROUND

There is a lack of knowledge about factors associated with health-related quality of life in cardiac arrest survivors and their spouses. In addition, survivors and spouses are likely to affect each other's health-related quality of life.

AIMS

The aim was to investigate if a distressed personality and perceived control among cardiac arrest survivors and their spouses were associated with their own and their partner's health-related quality of life.

METHODS

This dyadic cross-sectional study used the actor-partner interdependence model to analyse associations between a distressed personality (type D personality), perceived control (control attitudes scale), and health-related quality of life (EQ index and EQ visual analogue scale).

RESULTS

In total, 126 dyads were included in the study. Type D personality and perceived control in cardiac arrest survivors were associated with their own health-related quality of life. In their spouses, a significant association was found for type D personality but not for perceived control. In addition, type D personality and perceived control in survivors were associated with health-related quality of life in their spouses.

CONCLUSIONS

Type D personality and perceived control are factors that might be considered during post cardiac arrest, because of the associations with health-related quality of life in survivors and spouses. More research is needed to test psychosocial interventions in the cardiac arrest population in order to improve health-related quality of life.

Evidence of Arabic Version of the Control Attitude Scale-Revised Efficacy to Measure Perceived Control in Acute Myocardial Infarction Patients

BACKGROUND AND PURPOSE

Perceived control plays a vital role in controlling negative consequences during disease process. The purpose of this study was to test the psychometric properties of the Arabic version of the Control Attitudes Scale-Revised (CAS-R) among patients with acute myocardial infarction (AMI).

METHODS

375 patients with a confirmed diagnosis of AMI participated in this study. Reliability was assessed by Cronbach's alpha, item-total correlations, and interitem correlations. Construct validity was examined by hypotheses testing.

RESULTS

Cronbach's alpha was .85. All items were homogenous, since item-total correlation coefficients and interitem correlation coefficients were acceptable. Perceived control has a protective effect against anxiety and complications, supporting the construct validity.

CONCLUSIONS

The Arabic version of the CAS-R is a valid and reliable instrument to measure perceived control in patients with AMI.

Patients with ST segment elevation myocardial infarction: moderating effect of perceived control on the relationship between depression and in-hospital complications

BACKGROUND

Cardiovascular diseases remain the top global killer, with nearly 80% of related mortalities occurring in developing countries. Over half of cardiovascular diseases' mortality is due to coronary heart disease, which is commonly linked to acute myocardial infarction. Psychological factors (i.e., depression and anxiety) after acute myocardial infarction are associated with higher levels of complications and mortality. Perceived control moderated the effect of anxiety on complications in different cardiac populations, but impacts on depression and complications after acute myocardial infarction are not well studied. This study explores the moderating effect of perceived control on the relationship between depression and complications after ST segment elevation myocardial infarction.

METHODS

Three hundred patients with a confirmed diagnosis of ST segment elevation myocardial infarction participated in this prospective observational study. Patients answered socio-demographic data, the depression subscale of the Hospital Anxiety and Depression Scale (HADS), and the Control Attitude Scale-Revised (CAS-R) questionnaires. In-hospital complications and all other necessary data were extracted from medical records after discharge. Data were analyzed using logistic regression.

RESULTS

24% developed at least one complication. Patients with high depression scores (8-21) were more likely to develop complications (χ² = 34.15, p < .001) than those with low depression scores (0-7). Patients with high levels of perceived control had lower levels of depression than those with low perceived control (mean [SD], 9.47 [6.43] vs. 12.31 [6.66], p < .001). The results of logistic regression showed that perceived control moderated the association between depression and complications, since depression scores, perceived control scores, and the interaction between depression and perceived control were significant predictors of complications. Participants with high depression and low perceived control had the highest rate of complications (31.5% vs. 15.4%, P < .001).

CONCLUSIONS

Depression increased complications after ST segment elevation myocardial infarction. Perceived control moderated this relationship. Assessment of depression and enhancement of perceived control in patients with acute myocardial infarction can decrease complications and improve outcomes.

Checking the moderating effect of perceived control on the relationship between anxiety and postoperative hospital length of stay among coronary artery bypass graft patients

Background

Coronary artery disease (CAD) is the most common cardiovascular disease (CVD). Coronary artery bypass graft (CABG) surgery is the most common treatment used for CAD. Patients undergoing this surgery are always anxious, which might increase complications in the postoperative period, especially prolongation of postoperative length of stay (LOS). It has been shown that perceived control (PC) moderated the relationship between anxiety and complications in a cardiac population, but its effect has not been studied in post-CABG.

Aim

The aim of this study was to check if there is a moderating effect for the PC on the relationship between anxiety and LOS post-CABG.

Patients and methods

A non-experimental, prospective, observational study was conducted with a consecutive sample of 250 patients who underwent elective CABG from four hospitals in Amman, Jordan. PC was measured by the Arabic version of the Control Attitude Scale-Revised (CAS-R), and anxiety was measured by the Arabic version of the anxiety subscale of Hospital Anxiety and Depression Scale. LOS and other needed information were obtained from patients’ medical records.

Results

Preoperative anxiety was significantly higher than postoperative anxiety (mean [SD]: 12.80 [6.70] vs 11.01 [6.74], P<0.001). Female patients were more anxious and had longer LOS compared to male patients. In stepwise regression, anxiety and PC scores were independent predictors for LOS. Every unit increase in preoperative anxiety increased LOS by 0.381 days, and every unit increase in PC decreased the postoperative LOS by 0.210 days. Moderating effect was checked by simple slope analysis for high (+1 SD) and low (−1 SD) levels of PC. Patients with high anxiety and low PC had the longest LOS, and patients with low anxiety and high PC had the shortest LOS, indicating the moderating effect of PC on the relationship between anxiety and LOS.

Conclusion

High levels of anxiety were associated with longer LOS after CABG. PC moderates this relationship. Enhancing PC in this population can improve outcomes and decrease LOS and morbidity.

Depressive Symptoms and Complications Early after Acute Myocardial Infarction: Gender Differences

Background:

Cardiovascular disease is the first leading cause of death worldwide. Coronary heart disease is the most common manifestation of cardiovascular disease. Acute myocardial infarction is the primary manifestation of coronary heart disease. Depression is a common and predicted complication after acute myocardial infarction. Limited studies evaluated gender differences in depressive symptoms after acute myocardial infarction especially in developing countries.

Objective:

The study aimed to determine whether there was a difference in depression levels and rate of complications based on gender early after acute myocardial infarction.

Method:

This was a prospective comparative study on 230 patients (150 men and 80 women) with a confirmed diagnosis of acute myocardial infarction. All participants signed an informed consent, filled sociodemographic and clinical questionnaire and the Depression Subscale of the Hospital Anxiety and Depression Scale. Clinical data were abstracted from the participants’ medical record after discharge.

Results:

Eighty-six participants (37.4%), 54 men and 32 women, developed 1 or more complications during hospitalization. Female patients were more depressed (14.4±3.5 vs. 8.3 ± 2.6) and developed more complications (1.9 ± 0.9 vs. 0.8 ± 0.5) than male patients did. Depressive symptoms increased the occurrence of complication by 40% and 33% for female and male patients respectively after controlling for sociodemographic and clinical variables.

Conclusion:

Depressive symptoms independently predicted complications after acute myocardial infarction in both men and women. The inclusion of depression assessment tools in acute myocardial infarction treatment protocols is highly recommended.

Perceived control and health-related quality of life in heart transplant recipients

BACKGROUND

Perceived control has been associated with improved mental health and health-related quality of life (HRQOL) in cardiac populations. However, this concept has not been well-studied in heart transplant groups.

AIMS

We examine the relationship of perceived control to symptoms of anxiety and depression and HRQOL after transplant. We also examine the extent to which anxiety and depressive symptoms mediate the relationship between perceived control and HRQOL.

METHODS

Our cross-sectional analysis included 113 adult heart transplant patients from the NEW HEART study. High versus low perceived control groups were determined by median split for chi-square and t-test analyses. Hierarchical multiple linear regression models were used to examine the influence of perceived control on symptoms of depression and anxiety and HRQOL. Mediation analyses included Baron and Kenny's four-step regression approach and Preacher and Hayes' bootstrapping technique to test the indirect effect of perceived control on HRQOL.

RESULTS

Heart transplant patients who reported lower perceived control were more likely to be female ( p=0.003), and had significantly more depressive symptoms ( p<0.001) and anxiety ( p<0.001), and lower HRQOL ( p<0.001) than those with higher perceived control. Perceived control was a significant predictor in regression models of depressive and anxiety symptoms and HRQOL. In mediation analyses, depressive and anxiety symptoms mediated the effect of perceived control on HRQOL.

CONCLUSION

Perceived control is associated with improved depressive and anxiety symptoms and HRQOL after transplant. The relationship between perceived control and HRQOL is mediated by depressive and anxiety symptoms. Future interventions should target perceived control to improve overall HRQOL.

Perceived control moderates the relationship between anxiety and in-hospital complications after ST segment elevation myocardial infarction

Purpose

Anxiety is a common psychological response after acute myocardial infarction and might be associated with higher levels of in-hospital complications. Perceived control might moderate this relationship, but the effect of this method has not been checked in developing countries. Therefore, the objectives of this study were as follows: 1) to check if anxiety was an independent predictor of in-hospital complications after acute myocardial infarction; and 2) to check if perceived control moderates the relationship between anxiety and in-hospital complications after acute myocardial infarction.

Patients and methods

This was a prospective observational study among 500 patients with a confirmed diagnosis of ST segment elevation myocardial infarction recruited from three private hospitals in Amman, Jordan. Anxiety was measured by the Anxiety subscale of Hospital Anxiety and Depression Scale, and perceived control was measured by the Arabic version of the Control Attitude Scale-Revised.

Results

One hundred and forty patients (28%) developed at least one complication during hospitalization. Two hundred and fifty-five patients had low anxiety scores (≤7), and 245 patients had high anxiety scores (≥8). Patients with high levels of perceived control had lower levels of anxiety (mean [SD]; 5.3 [3.6] vs 14.1 [6.3], P<0.001) than those with low perceived control. In logistic regression, anxiety was an independent predictor of in-hospital complications after controlling for sociodemographic and clinical variables (odds ratio: 1.24, 95% CI, 1.08–1.41, P<0.01). Moreover, the interaction of anxiety and perceived control was a significant predictor of complications.

Conclusion

Anxiety was associated with increased risk of in-hospital complications after acute myocardial infarction independent of sociodemographic and clinical variables. Perceived control had a moderating effect for this association since the combination of low perceived control and high anxiety scores was associated with the greatest risk for complications. Supporting patients’ levels of perceived control can decrease complications, morbidities, and mortality after acute myocardial infarction.

Prevalence, Defining Characteristics, and Related Factors of the Nursing Diagnosis of Anxiety in Hospitalized Medical-Surgical Patients

PURPOSE

To document the prevalence of the nursing diagnosis of anxiety in hospital patients, based on its level of severity, defining characteristics (DCs), and other related factors, and to identify the key DCs that serve as predictors of clinically significant anxiety (CSA).

DESIGN

Cross-sectional study. We enrolled 116 consecutive adult patients hospitalized from October 10 to 16, 2016, in medical-surgical wards within the first 48 hr of admission.

METHODS

The potential DCs and related factors of anxiety were collected based on the NANDA International terminology. Anxiety was considered clinically significant when presenting at moderate, severe, or panic level. The differences in DC prevalence among patients having or not having CSA were analyzed by unpaired student's t-test. Multivariate analysis was used to examine the independent association between the DCs and CSA.

FINDINGS

The prevalence of CSA was 36.2% and was significantly higher in patients who were older, female, and taking anxiolytic drugs, and among those who had cancer. The most frequent related factor for CSA was major change in health status. In the logistic regression, the presence of the DCs helplessness, altered attention or concentration, and anguish independently increased the odds of having CSA, whereas subjects presenting with Diminished ability to problem-solve had about a 96% reduction in the likelihood to suffer from such a condition.

CONCLUSIONS

A high prevalence of CSA among medical-surgical patients was shown. Furthermore, a critical cluster of DCs useful to identify CSA was found.

CLINICAL RELEVANCE

The ability to accurately diagnose CSA should help prescribe and deliver the appropriate nursing interventions.

Person-centred care improves self-efficacy to control symptoms after acute coronary syndrome: a randomized controlled trial

BACKGROUND

Person-centred care (PCC) aims to engage patients as active partners in their care and treatment to improve the management of their illness. Self-efficacy is an important concept and outcome in PCC as it refers to a patient's belief in their capability to manage the events that affect their lives. Recovery after acute coronary syndrome (ACS) is demanding and a PCC approach may promote self-efficacy and thereby facilitate recovery.

AIM

The purpose of this study was to evaluate whether a PCC intervention was able to improve self-efficacy after hospitalization for ACS.

METHODS

In a randomized controlled trial, patients <75 years of age and hospitalized for ACS were assigned to either a usual care group or a PCC intervention group. Self-efficacy was assessed at baseline and up to six months after discharge using the Swedish Cardiac Self-Efficacy Scale (S-CSES), which consists of three dimensions: control symptoms, control illness and maintain functioning.

RESULTS

In total, 177 patients were included in the study: 93 in the usual care group and 84 in the PCC group. At the one-month follow-up the PCC group had improved significantly more (p=0.049) on the control symptoms dimension (mean change 0.81; SD 3.5 versus mean change -0.20; SD 3.0). No difference between groups was seen at the six-month follow-up in any of the S-CSES dimensions.

CONCLUSIONS

Our results indicate that PCC added to usual care promotes and hastens the development of patients' confidence in their ability to manage symptoms during recovery after ACS. This underlines the importance of initiating and establishing partnerships between patients and health care professionals as early as possible after ACS.

The Cardiac Self-Efficacy Scale, a useful tool with potential to evaluate person-centred care

BACKGROUND

Cardiac self-efficacy is a person's belief in his/her ability to manage the challenges posed by a coronary disease, and its role has been evaluated in several coronary populations using the Cardiac Self-Efficacy Scale (CSE Scale). Self-efficacy has an important role in person-centred care, however there is a lack of appropriate instruments that evaluate person-centred interventions.

AIM

The purpose of this study was to validate the CSE Scale by examining its psychometric properties as a first step in evaluating a person-centred care intervention in persons with acute coronary syndrome (ACS).

METHODS

The study sample consisted of 288 persons (72 women, 216 men) who completed the Swedish version of the CSE Scale two months after hospitalisation for an ACS event. Construct validity was psychometrically evaluated using confirmatory factor analysis. Additionally, convergent and discriminant validity were tested using correlation analyses.

RESULTS

The results revealed that the CSE Scale was represented by three dimensions (control symptoms, control illness and maintain functioning). The analyses also showed that the CSE Scale is suitable for providing a total summary score that represents a global cardiac self-efficacy dimension. Evaluation of convergent and discriminant validity showed the expected correlations.

CONCLUSION

The CSE Scale is a valid and reliable measure when evaluating self-efficacy in patients with ACS. It also seems to be a useful tool to promote person-centred care in clinical practice since it may offer useful guidance in the dialogue with the patient in the common creation of a personal health plan.

On-going palliative care enhances perceived control and patient activation and reduces symptom distress in patients with symptomatic heart failure: a pilot study

INTRODUCTION

There is a paucity of research about the impact of palliative care (PC) on perceived control (i.e. one's perceived influence over outcomes or events in the environment) and activation (i.e. ability to self-manage) in patients with symptomatic heart failure (HF). Likewise, little is known about the association between perceived control, activation, and symptom distress in this patient population. We hypothesized that patients with advanced HF who received ongoing PC services (i.e. ≥2 PC consultations) vs no access or a single PC consultation would have greater improvements in perceived control and activation and greater reductions in symptom distress three months post-discharge for HF exacerbation.

METHODS

Forty-two patients (average age 53.9±8.0 years; predominantly male (72%), White (61%) and married (69%)) participated in the study. However, only 36 (85.7%) patients completed an outpatient PC consultation of which 29 (69%) patients returned for additional follow-up visits with the PC team. Data on perceived control, activation, and symptom distress were collected at baseline and three months. Parametric statistical models were applied to draw conclusions.

RESULTS

Findings showed that the patients who received ≥2 PC consultations had greater improvements in perceived control and activation than their counterparts; these increases were associated with greater reductions in symptom distress.

CONCLUSION

Our findings suggest that on-going PC interventions enhance perceived control and activation in patients with advanced HF and open up the possibility of planning larger studies to assess the effect of PC on these variables as possible mediators to improvements in self-management and clinical outcomes.

A psychometric evaluation of the four-item version of the Control Attitudes Scale for patients with cardiac disease and their partners

BACKGROUND

The four-item Control Attitudes Scale (CAS) was developed to measure control perceived by patients with cardiac disease and their family members, but extensive psychometric evaluation has not been performed.

OBJECTIVE

The aim was to translate, culturally adapt and psychometrically evaluate the CAS in a Swedish sample of implantable cardioverter defibrillator (ICD) recipients, heart failure (HF) patients and their partners.

METHODS

A sample (n=391) of ICD recipients, HF patients and partners were used. Descriptive statistics, item-total and inter-item correlations, exploratory factor analysis, ordinal regression modelling and Cronbach's alpha were used to validate the CAS.

RESULTS

The findings from the factor analyses revealed that the CAS is a multidimensional scale including two factors, Control and Helplessness. The internal consistency was satisfactory for all scales (α=0.74-0.85), except the family version total scale (α=0.62). No differential item functioning was detected which implies that the CAS can be used to make invariant comparisons between groups of different age and sex.

CONCLUSIONS

The psychometric properties, together with the simple and short format of the CAS, make it to a useful tool for measuring perceived control among patients with cardiac diseases and their family members. When using the CAS, subscale scores should be preferred.
