The Self-Care of Heart Failure Index version 7.2: Further psychometric testing

Patient-Centered mHealth Intervention to Improve Self-Care in Patients With Chronic Heart Failure: Phase 1 Randomized Controlled Trial

BACKGROUND

Heart failure (HF) is one of the most common causes of hospital readmission in the United States. These hospitalizations are often driven by insufficient self-care. Commercial mobile health (mHealth) technologies, such as consumer-grade apps and wearable devices, offer opportunities for improving HF self-care, but their efficacy remains largely underexplored.

OBJECTIVE

The objective of this study was to examine the feasibility, acceptability, safety, and preliminary efficacy of a patient-centered mHealth intervention (iCardia4HF) that integrates 3 consumer mHealth apps and devices (Heart Failure Health Storylines, Fitbit, and Withings) with a program of individually tailored SMS text messages to improve HF self-care.

METHODS

We conducted a phase 1 randomized controlled trial. Eligible patients had stage C HF, were aged ≥40 years, and had New York Heart Association (NYHA) class I, II, or III HF. Patients were randomly assigned to either iCardia4HF plus usual care or to usual care only and were observed for 8 weeks. Key feasibility measures were recruitment and retention rates. The primary efficacy outcome was change in HF self-care subscale scores (maintenance, symptom perception, and self-care management) at 8 weeks, assessed with the Self-Care Heart Failure Index (SCHFI; version 7.2). Key secondary outcomes were modifiable behaviors targeted by the intervention (health beliefs, self-efficacy, and HF knowledge), health status, and adherence to daily self-monitoring of 2 core vital signs (body weight and blood pressure).

RESULTS

A total of 27 patients were enrolled in the study and randomly assigned to iCardia4HF (n=13, 48%) or usual care (n=14, 52%). Of these 27 patients, 11 (41%) in the intervention group (iCardia4HF) and 14 (52%) in the usual care group started their assigned care and were included in the full analysis. Patients' mean age was 56 (SD 8.3) years, 44% (11/25) were female, 92% (23/25) self-reported race as Black, 76% (19/25) had NYHA class II or III HF, and 60% (15/25) had HF with reduced left ventricular ejection fraction. Participant retention, completion of study visits, and adherence to using the mHealth apps and devices for daily self-monitoring were high (>80%). At 8 weeks, the mean group differences in changes in the SCHFI subscale scores favored the intervention over the control group: maintenance (Cohen d=0.19, 95% CI -0.65 to 1.02), symptom perception (Cohen d=0.33, 95% CI -0.51 to 1.17), and self-care management (Cohen d=0.25, 95% CI -0.55 to 1.04). The greatest improvements in terms of effect size were observed in self-efficacy (Cohen d=0.68) and health beliefs about medication adherence (Cohen d=0.63) and self-monitoring adherence (Cohen d=0.94). There were no adverse events due to the intervention.

CONCLUSIONS

iCardia4HF was found to be feasible, acceptable, and safe. A larger trial with a longer follow-up duration is warranted to examine its efficacy among patients with HF.

A nurse-led coaching intervention with home telemonitoring for patients with heart failure: Protocol for a feasibility randomized clinical trial

Poor treatment adherence and lack of self-care behaviors are significant contributors to hospital readmissions of people with heart failure (HF). A transitional program with non-invasive telemonitoring may help sustain patients and their caregivers to timely recognize signs and symptoms of exacerbation. We will conduct a Randomized Clinical Trial (RCT) to evaluate the feasibility and acceptability of a 6-month supportive intervention for patients discharged home after cardiac decompensation. Forty-five people aged 65 years and over will be randomized to either receive a supportive intervention in addition to standard care, which combines nurse-led telephone coaching and a home-based self-monitoring vital signs program, or standard care alone. Four aspects of the feasibility will be assessed using a mixed-methods approach: process outcomes (e.g., recruitment rate), resources required (e.g., adherence to the intervention), management data (e.g., completeness of data collection), and scientific value (e.g. 90- and 180-day all-cause and HF-related readmissions, self-care capacity, quality of life, psychological well-being, mortality, etc.). Participants will be interviewed to explore preferences and satisfaction with the intervention. The study is expected to provide valuable insight into the design of a definitive RCT.

Evaluating dyadic factors associated with self-care in patients with heart failure and their family caregivers: Using an Actor-Partner Interdependence Model

Dyadic conditions of patients with heart failure and their caregivers may affect both patient self-care and caregiver contribution to patient self-care (CCPS). The purpose of this study was to examine the relationships of patient-caregiver physical function and depressive symptoms to the patient self-care (maintenance and management) and CCPS. Data from 55 were analyzed using an Actor-Partner Interdependence Model to address the aim through AMOS. Patient self-care was very poor. Better patient physical function was related to better patient self-care management (actor effect) and poorer CCPS maintenance (partner effect). Better caregiver physical function was related to CCPS management (actor effect). Severer patient depressive symptoms were related to poorer patient self-care maintenance (actor effect) and poorer CCPS management (partner effect). Physical function and depressive symptoms in patient-caregiver dyads were related to patient self-care and CCPS. To improve patient self-care and CCPS, dyadic support for physical function and depressive symptoms is needed.

Heart Failure Knowledge Assessment and Perceived Patient Satisfaction in Heart Failure Units: A Multicenter Observational Survey

Background

Self-care and empowerment promotion in patients with heart failure (HF) is essential for improving their prognosis, but there is limited information concerning the patients' depth of knowledge about this pathology as well as patient satisfaction within heart failure units (HFUs). Our objective was to assess both aspects in a cohort of patients regularly followed-up HFUs.

Methods

A multicenter, observational study was conducted with consecutive patients followed in 14 HFUs between June and November 2023. It was based on a cross-sectional survey comprising 23 questions related to demographics, knowledge/self-care, and the subjective assessment of perceived quality and satisfaction in HFUs.

Results

281 patients were included (36.7% women, 74.7% aged over 65 years). 48% had hospitalizations for HF or sought emergency department services within the preceding year. The mean correct responses related to knowledge were 9.7 ± 2.3 (80.7% of the total), and 53 patients (18.9%) answered all knowledge questions correctly. 211 (79.6%) could identify potential HF decompensation with abrupt weight gain, and 196 (74.2%) recognized at least three additional signs of worsening HF. 266 patients (98.2%) were likely or very likely to recommend HFUs, and 194 (89.8%) positively appreciated the experience at the day hospital.

Conclusions

Patients followed up in HFUs showed adequate but improvable knowledge and capacity for self-care, with a high level of satisfaction.

Generic and disease-specific self-care instruments in older patients affected by multiple chronic conditions: A descriptive study

AIMS

To describe and compare generic and disease-specific self-care measures in patients with multiple chronic conditions (MCCs) in the three dimensions of self-care maintenance, monitoring, and management.

DESIGN

Multicentre cross-sectional study.

METHODS

Patients aged 65 and over with MCCs. We used Self-Care of Chronic Illness Inventory to measure generic self-care, Self-care of Diabetes Inventory to measure self-care in diabetes mellitus, Self-Care of Heart Failure (HF) Index to measure self-care in HF, and Self-Care of Chronic Obstructive Pulmonary Disease Inventory to measure self-care in chronic lung diseases.

RESULTS

We recruited 896 patients. Multimorbid patients with diabetes had lower scores on the self-care maintenance scale, and diabetic patients in insulin treatment on the generic management scale than on the disease-specific instrument. Multimorbid patients with HF or chronic lung diseases scored higher on generic self-care maintenance and monitoring scales than disease-specific ones. There was a partial consistency between the generic and disease-specific self-care maintenance and management. Inadequate behaviours were recorded in disease-specific self-care monitoring rather than generic ones.

CONCLUSIONS

Older patients affected by MCCs scored differently in the generic and disease-specific instruments, showing inadequate self-care in some of the three self-care dimensions.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

The choice between generic and disease-specific instruments to use in clinical practice and research should be made considering the specific aims, settings, patients characteristics, and knowledge of the different performance of the instruments by users.

IMPACT

No study has described and compared generic and specific self-care measures in patients affected by MCCs. Knowing these differences can help nurses choose the most suitable measure for their aims, context, and patients and plan generic and disease-specific self-care educational interventions for those behaviours in which MCCs patients perform poorly.

PATIENT CONTRIBUTION

Patients were informed about the study, provided informed consent, and answered questionnaires through interviews.

Psychometric Testing of the Thai Version of Self-Care of Chronic Illness Inventory Version 4c in Patients With Stroke

BACKGROUND

Self-Care of Chronic Illness Inventory version 4c is a non-disease-specific self-care measure used in individuals with multiple chronic conditions. This instrument may be applied to patients with specific diseases such as stroke.

OBJECTIVE

The aim of this study was to evaluate the psychometric properties of the Thai version of the Self-Care of Chronic Illness Inventory version 4c in patients with stroke.

METHODS

This multicenter, cross-sectional study adhered to the COSMIN (Consensus-based Standards for the Selection of Health Measurement Instruments) guidelines and enrolled patients with stroke from 16 primary care centers in southern Thailand. Structural validity was assessed using confirmatory factor analysis, internal consistency reliability using Cronbach α coefficient and global reliability index, and test-retest reliability using intraclass correlation coefficients.

RESULTS

The final analysis included a total of 350 participants. Confirmatory factor analysis supported the 2-factor Self-Care Maintenance scale structure, although the item allocation to the dimensions differed from that of the original model. The Self-Care Monitoring scale demonstrated a 1-factor structure with permitted residual covariance. The Self-Care Management scale maintained a 2-factor structure, similar to that of the original model. Simultaneous confirmatory factor analysis of the combined items supported the general model with the 3 scales. The Self-Care Maintenance scale exhibited marginally adequate α (0.68) and ω (0.66) coefficients, and an adequate composite reliability index (0.79). The other 2 scales demonstrated adequate α (range, 0.79-0.86), ω (range, 0.75-0.86), and composite reliability (range, 0.83-0.86) indices. Intraclass correlation coefficients showed adequate test-retest reliability for all scales (range, 0.76-0.90).

CONCLUSIONS

The generic self-care measure, Self-Care of Chronic Illness Inventory version 4c, demonstrated strong psychometric properties in patients with stroke. This instrument may be a valuable tool for assessing stroke self-care in Thailand.

The caregiver contribution to self-care of stroke inventory (CC-SCSI): evaluation of psychometric characteristics

BACKGROUND

The caregiver contribution to self-care plays an important role in improving the health outcomes of chronic patients, which needs urgent attention. However, it has been hindered by the lack of a tailored instrument that assesses the caregiver contribution to self-care of stroke.

OBJECTIVES

To test the psychometric characteristics of the caregiver contribution to self-care of stroke Inventory (CC-SCSI) in health care practice.

METHODS

Participants were recruited in Henan Province from March 2021 to October 2022, utilizing a multicenter stratified sampling approach. A 23-item self-report CC-SCSI with 3 separate scales measuring caregiver contribution to self-care maintenance of stroke, caregiver contribution to self-care monitoring of stroke and caregiver contribution to self-care management of stroke was tested for validity through discriminant validity, confirmatory factor analysis, concurrent validity and convergent validity. The reliability was tested by Cronbach's α coefficient and test-retest reliability. Qualitative data were analysed using thematic analysis. A STROBE checklist was used.

RESULTS

The three scales of the CC-SCSI exhibited good discriminant validity. Confirmatory factor analysis supported the three-factor structure of the Caregiver Contribution to Stroke Self-Care Maintenance and Management scales and the one-factor structure of the Caregiver Contribution to Stroke Self-Care Monitoring scale. The moderate correlation between the CC-SCSI and the Self-Care of Stroke Inventory indicated acceptable concurrent validity. The moderate correlation between the CC-SCSI and the Caregiver Contribution to Self-Care of Chronic Illness Inventory indicated acceptable convergent validity. Cronbach's αs for the Caregiver Contribution to Self-Care Maintenance, Self-Care Monitoring, and Self-Care Management scales ranged from 0.876 to 0.974. Test-retest reliability showed average ICC values ranging from 0.828 to 0.903 (P < 0.001).

CONCLUSIONS

The 23-item CC-SCSI presents good psychometric properties and could be used to explore the caregiver contribution to stroke self-care in health care practice and research.

Psychometric Evaluation of the Traditional Chinese Version of the Self-Care of Heart Failure Index Version 7.2

BACKGROUND

The Self-Care of Heart Failure Index (SCHFI) is a widely used instrument used to measure self-care in both research and clinical settings. The lack of a psychometric evaluation of the traditional Chinese version of the SCHFI (SCHFI-C) might limit its utilization in non-Mainland Chinese populations such as Hong Kong, Macau, and Taiwan.

OBJECTIVE

This study aimed to evaluate the psychometric properties of the SCHFI-C v.7.2.

METHODS

Participants included 365 adults with heart failure. Breslin's method of translation was used to translate the SCHFI v.7.2 into traditional Chinese. Exploratory factor analysis was conducted to examine the dimensionality structure of each scale. Then, composite reliability was calculated to assess the reliability of 3 scales. Construct validity was examined by hypothesis testing and known-group comparisons.

RESULTS

The results of exploratory factor analysis suggest its multidimensionality of each scale. More specifically, the findings indicated a unique internal structure of the self-care maintenance ("lifestyle-related behaviors" and "consulting behaviors") and self-care management ("self-reliance behaviors" and "help-seeking behaviors") scales. The composite reliability of 3 scales were 0.81, 0.88, and 0.82, respectively, reaching adequate level. As for construct validity, the significant associations between the 3 SCHFI domains and self-care confidence as well as significant group difference among patients of different ages and educational backgrounds supported good construct validity.

CONCLUSIONS

This study provides evidence of the reliability and validity of the SCHFI-C v.7.2. The traditional SCHFI-C v.7.2 can serve as a valid and reliable outcome measure to evaluate the effects of self-care-promoting interventions.

Psychometric properties of the Japanese version of the Self-Care of Heart Failure Index version 7.2

AIMS

It is more important for patients with heart failure (HF) to objectively identify their self-care status. The Self-Care of Heart Failure Index (SCHFI) version 7.2 is a reliable and valid instrument comprising three scales: self-care maintenance, symptom perception, and self-care management. We aimed to translate the SCHFI v.7.2 into Japanese and test its validity and reliability.

METHODS AND RESULTS

This was a cross-sectional study. Two translators performed forward and backward translations between English and Japanese. To assess structural validity, confirmatory factor analyses were performed using the structure of the original version. To assess convergent validity, the associations between each scale and self-care self-efficacy were evaluated. To assess internal consistency, model-based internal consistency coefficients were calculated. Participants were 314 Japanese outpatients with HF (mean age: 72.8 ± 12.8 years). Regarding structural validity, all scales showed adequate model fit indices, supporting a two-factor structure with items similar to those in the original version. However, to improve the model fit indices, it was necessary to add error correlations for the self-care maintenance and symptom perception scales. Regarding convergent validity, all scales showed significant associations with self-care self-efficacy. Regarding internal consistency, the model-based internal consistency coefficients were sufficient for all scales (0.739, 0.908, and 0.783 for the self-care maintenance, symptom perception, and self-care management scales, respectively).

CONCLUSION

The Japanese version of the SCHFI v.7.2 had adequate validity and reliability. This instrument is useful for assessing self-care in Japanese HF patients. However, factors influencing self-care should be considered when interpreting results.

Psychometric properties of self-reported measures of self-management for chronic heart failure patients: a systematic review

AIMS

The aim of this study is to identify and assess the psychometric properties of patient-reported outcome measures (PROMs) of self-management for chronic heart failure (CHF) patients.

METHODS AND RESULTS

Eleven databases and two websites were searched from the inception to 1 June 2022. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist was used to assess the methodological quality. The COSMIN criteria were used to rate and summarize the psychometric properties of each PROM. The modified Grading of Recommendation Assessment, Development, and Evaluation was used to assess the certainty of evidence. In total, 43 studies reported on the psychometric properties of 11 PROMs. Structural validity and internal consistency were the parameters evaluated most frequently. Limited information was identified on hypotheses testing for construct validity, reliability, criterion validity, and responsiveness. No data regarding measurement error and cross-cultural validity/measurement invariance were achieved. High-quality evidence on psychometric properties was provided for Self-care of Heart Failure Index (SCHFI) v6.2, SCHFI v7.2, and European Heart Failure Self-care Behavior Scale 9-item (EHFScBS-9).

CONCLUSION

Based on the findings from the included studies, SCHFI v6.2, SCHFI v7.2, and EHFScBS-9 could be recommended to evaluate self-management for CHF patients. Further studies are necessary to evaluate more psychometric properties, such as measurement error, cross-cultural validity/measurement invariance, responsiveness, and criterion validity, and carefully evaluate the content validity.

Psychometric Testing of the Chinese Version of the Self-care of Heart Failure Index Version 7.2

BACKGROUND

Self-care is essential in patients with heart failure (HF).

OBJECTIVE

Our objective was to test psychometric properties of the Chinese version of the Self-care of Heart Failure Index version 7.2 (SCHFI v7.2-C).

METHODS

The English version of SCHFI v7.2 was translated into Chinese using the modified Brislin translation model. Psychometric tests of the SCHFI v7.2-C were performed in 320 Chinese patients with HF. Content validity, confirmatory factor analysis, convergent validity, concurrent validity, discriminant validity, internal consistency, and test-retest reliability were examined to determine validity and reliability of the questionnaire. Validity and reliability were assessed for the self-care maintenance, symptom perception, and self-care management scales. SPSS 25.0 and Mplus 8.3 were used for data analysis.

RESULTS

Mean (SD) age of the sample was 61.2 (14.20) years. Scale content validity index ranged from 0.93 to 0.97 across the 3 scales. Results of confirmatory factor analysis supported structural validity of the 3 scales. Self-care was significantly associated with quality of life, and those with more HF experience had significantly better self-care than those with less experience, supporting construct validity. The SCHFI v7.2-C was associated with the 12-item European Heart Failure Self-care Behavior Scale. Cronbach α coefficients for the self-care maintenance, symptom perception, and self-care management scales were 0.79, 0.89, and 0.77, respectively; their test-retest reliability was 0.76, 0.78, and 0.75, respectively.

CONCLUSION

The SCHFI v7.2-C is a valid and reliable instrument that can be used in Chinese patients with HF.

A Nurse-Led Model of Care with Telemonitoring to Manage Patients with Heart Failure in Primary Health Care: A Mixed-Method Feasibility Study

Purpose

To determine whether a nurse-led care model with telemonitoring in primary care for patients with stable heart failure and their caregivers is feasible and acceptable.

Patients and Methods

A mixed-methods feasibility study was conducted. Patients with stable heart failure and their caregivers were consecutively enrolled from March 2021 to April 2022. Participants were managed by nurses in a community health center through education and monitoring with a mobile app. The outcomes were feasibility outcomes, self-care outcomes, and qualitative acceptability and satisfaction. Quantitative and qualitative outcomes were linked to understanding how the model of care might benefit patients.

Results

Twenty-six patients and nine of their caregivers were enrolled. Ten participants used the mobile app. Nineteen patients and eight caregivers were interviewed. Participants who improved their self-care appreciated the help in finding coping strategies, being close to the clinic, and feeling cared for. Participants with fewer improvements in self-care perceived the model of care as useless and were far from the centre. Participants decided to use the app mainly for usefulness prevision, and most of them were satisfied.

Conclusion

The model of care was not successful in recruiting patients, and adjustments are needed to improve the recruitment strategy and to engage people who perceive the model of care as not useful or unable to use the app.

Psychometric properties and measurement invariance of the Arabic Self-Care Inventory

BACKGROUND

Self-care is a fundamental aspect of health and well-being for healthy individuals and those with chronic illnesses. However, the available self-care measurement instruments have limited support regarding their psychometric properties. Research about the validation of comprehensive, theory-based self-care tools in the Arabic language and culture is also limited. In addition, many self-care measurement tools are available only for people with chronic illnesses.

OBJECTIVE

To examine the psychometric properties of the Arabic version of the Self-care Inventory (SCI) in the general adult population in Jordan.

METHODS

This study was conducted using a cross-sectional design. Data collection was performed using a demographics questionnaire, and Arabic versions of the SCI, Self-care Self-Efficacy, and the Center for Epidemiologic Studies Depression Scale-revised. SPSS and AMOS were used to analyze the data. Data analysis was conducted by performing confirmatory factor analysis, measurement invariance, internal consistency, and bivariate correlations.

RESULTS

The results revealed that the SCI comprises three scales: self-care maintenance, self-care monitoring, and self-care management. The goodness of mode fit indices showed that the models of these scales fit the data well by meeting the following set a priori criteria: (RMSEA < .07, CFI > .95, and X2/df < 5). The factor loadings of the individual items of the SCI provided further evidence about the factor structure of the three scales. Regarding measurement invariance, the results indicated that partial invariance across participants' sex is assumed. The values of both Cronbach's α and composite reliability showed that the internal consistency of the SCI is supported. Cronbach's α of the self-care maintenance, self-care monitoring, and self-care management were .82, .86, and .83, respectively.

CONCLUSION

The psychometric properties of the Arabic version of the SCI demonstrate its validity and reliability as a robust assessment tool for measuring self-care in the general adult population.

Cross-cultural adaptation and psychometric evaluation of the Thai version of Self-Care of Chronic Illness Inventory Version 4.c

Objectives

To translate and validate the Thai Self-Care of Chronic Illness Inventory version 4.c (Thai SC-CII v4.c) in individuals with chronic illnesses.

Methods

A scale translation and cross-sectional validation study was conducted. The English version was translated for Thai involved nine steps: preparation, forward translation, reconciliation, back-translation, back-translation review, harmonization, cognitive debriefing, review of cognitive debriefing and finalization, and proofreading. A cross-sectional study was conducted from July to November 2022 at 16 primary care centers in southern Thailand, involving 410 participants with at least one chronic condition. Validity assessments included structural, convergent, and discriminant validity. Concurrent validity examined correlations between SC-CII v4.c with the Self-Care Self-Efficacy Scale (SCSES) and self-perceived health. Internal coherence reliability was calculated using Cronbach's α coefficient, item-total correlation coefficients, and the composite reliability (CR) index.

Results

Thai SC-CII v4.c demonstrated excellent translational validity (κ = 0.99). The specified Self-Care Maintenance model fit well, with minor differences in health promoting behavior and illness-related behavior items compared to the original model. The original Self-Care Monitoring, and Self-Care Management models fit well with Thai data. Simultaneous confirmatory factor analysis confirmed a satisfactory fit of the full SC-CII v4.c. Convergent validity had partial support (average variance extracted = 0.23-0.51), and discriminant validity was established (heterotrait-monotrait ratios = 0.37-0.88). Concurrent validity was supported by positive correlations between each scale and overall SC-CII v.4c with SCSES (r = 0.25-0.65) and self-perceived health (r = 0.09-0.35). The Cronbach's α coefficient were adequate for all scales except the Self-Care Maintenance scale (Cronbach's α = 0.68), but the CR estimate improved the reliability of all three scales (ranging 0.80-0.82). All items had satisfactory item-total correlation coefficients (ranging 0.34-0.71), except the one pertaining to sleep.

Conclusions

The Thai SC-CII v4.c is valid and reliable for assessing self-care in various chronic illnesses. Further testing is recommended for patients with specific diseases.

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.

Psychometric Characteristics of the Self-Care of Chronic Illness Inventory in Older Adults Living in a Middle-Income Country

Chronic illness requires numerous treatments and self-care is essential in the care process. Evaluation of self-care behaviors facilitates the identification of patients' needs and optimizes education and care processes. This study aimed to test the psychometric characteristics (validity, reliability, and measurement error) of the Albanian version of the Self-Care of Chronic Illness Inventory (SC-CII). Patients with multiple chronic conditions and caregivers were recruited in outpatient clinics in Albania. The patients completed the SC-CII, which includes three scales: self-care maintenance, self-care monitoring, and self-care management. Factorial validity was tested for each scale, with confirmatory factor analysis. Reliability was evaluated with the composite coefficient, Cronbach's alpha, and the global reliability index for multidimensional scales. The construct validity was tested using hypothesis testing and known differences between groups. The measurement error was tested to assess responsiveness to changes. The self-care maintenance and self-care monitoring scales showed a unidimensional factorial structure, while the self-care management scale showed a bidimensional structure. Reliability estimates were adequate for all reliability coefficients. Construct validity was supported. The measurement error was adequate. The Albanian version of the SC-CII shows good psychometric properties in the Albanian sample.

Examining how congruence in and satisfaction with dyadic care type appraisal contribute to quality of life in heart failure care dyads

AIMS

Given the complexity of heart failure (HF) management, persons with HF and their informal caregivers often engage in dyadic illness management. It is unknown how congruent appraisal of dyadic HF care type is associated with dyadic health. Our aim was to examine how congruence in and satisfaction with appraisal of dyadic HF care type contribute to quality of life (QOL) for dyads.

METHODS AND RESULTS

This is a secondary analysis of cross-sectional data on 275 HF care dyads (patients 45.1% female, caregivers 70.5% female). Congruent appraisal and satisfaction were assessed using the Dyadic Symptom Management Type instrument. Quality of life was measured using the Short Form-12. Multilevel dyadic models were estimated to examine the contribution of congruence and satisfaction with dyadic care type to physical and mental QOL. Congruent appraisal of dyadic care type was positively associated with caregivers' mental QOL (B = 2.69, P = 0.026). Satisfaction with dyadic care type was positively associated with physical and mental QOL for persons with HF (B = 1.58, P = 0.011 and B = 2.09, P = 0.002, respectively) and informal caregivers (B = 1.70, P = 0.004 and B = 2.90, P < 0.001, respectively), while controlling for age, New York Heart Association class, daily hours spent together, relationship type, and congruence with dyadic care type.

CONCLUSION

Satisfaction with dyadic care type appraisal was a stronger contributor to QOL for HF care dyads, compared with congruent appraisals. It is important to understand reasons for dissatisfaction within the dyad to assist dyad members in reaching shared appraisals while managing HF.

Factors Related to Patients' Self-care and Self-care Confidence in Korean Patients With Heart Failure and Their Caregivers: A Cross-sectional, Correlational Study

BACKGROUND

The relationships of patient factors and caregiver contribution to patients' self-care to different types of self-care have been rarely examined in Korean patients with heart failure.

OBJECTIVE

The aim of this study was to examine patient (ie, age, depressive symptoms, and self-care confidence) and caregiver (ie, caregiver contribution to self-care maintenance and self-care management, and caregiver confidence in contributing to self-care) factors related to different types of self-care (ie, self-care maintenance, symptom perception, and self-care management) and self-care confidence in Korean patients with heart failure.

METHODS

In this cross-sectional, correlational study, data from 41 pairs of patients (mean age, 68.0 years) and caregivers (mean age, 54.1 years) were collected and analyzed using multiple regression.

RESULTS

Higher levels of self-care confidence in patients were related to higher levels of self-care maintenance in patients. Higher levels of self-care confidence in patients were related to higher levels of symptom perception. Higher levels of self-care confidence in patients and caregiver contribution to self-care maintenance were related to higher levels of self-care management. Less severe depressive symptoms in patients and higher levels of caregiver confidence in contributing to self-care were related to higher levels of self-care confidence.

CONCLUSION

Different patient and caregiver factors were related to different types of self-care and self-care confidence in Korean patients, but patients' self-care confidence was related to all types of self-care. Clinicians and researchers need to develop and deliver effective interventions to both patients and their caregivers to improve patients' self-care confidence and, in turn, self-care, considering different factors associated with each type of self-care.

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.

Effectiveness of a family customised online FOCUS programme aimed on building resiliency in dyad relationship to support dyadic illness management in persons with heart failure and their informal caregiver: a randomised clinical trial protocol

INTRODUCTION

Living with heart failure (HF), is a shared journey and arduous work for patients and their informal family caregivers. Given the key role and limited evidence of dyad illness management in improving dyad health in the context of HF, we developed a customisable, relationship focused, family online dynamic disease management programme-FOCUS programme-to improve dyad health for HF patients and their informal caregivers in China.

METHODS AND ANALYSIS

Based on the Theory of Dyadic Illness Management and the Systemic Transactional Model of Stress and Coping, the family customised online FOCUS programme has five modules: (1) family participatory; (2) open communication; (3) coping effectiveness; (4) uncertainty reduction and 5) shared dyad life stories. HF family dyads will be recruited in the cardiology wards of four university-affiliated hospitals in China. The dyads (N=142) will be randomly allocated to the intervention group that will receive the family customised online FOCUS programme, and the attention control group that will not receive elements of the FOCUS programme. Dyadic coping, HF somatic perception, self-care, anxiety and depression for patients and family caregivers and all-cause mortality and hospital admission for patients will be measured at baseline, 4 weeks (after the discharge, T1), 12 weeks (after the discharge, T2) and 24 weeks (after the discharge, T3). Statistical analysis will be performed using SPSS V. 22.0 software.

ETHICS AND DISSEMINATION

The study protocol was approved by the ethics committees of Tianjin Medical University (Reference number TMUHEC2019002) that covers all the centres enrolled in this study. The findings of this study will be published in scientific journals and will be presented at scientific conferences.

Patient Self-Care and Caregiver Contribution to Patient Self-Care of Chronic Conditions: What Is Dyadic and What It Is Not

OBJECTIVES

Self-care of chronic conditions involves both patients and their informal caregivers and therefore might be considered as a dyadic phenomenon. Nevertheless, empirical evidence supporting a dyadic construct is unavailable. This study aimed to explore the existence of a dyadic construct in self-care maintenance, monitoring, and management in patients affected by chronic conditions and their informal caregivers.

METHODS

This study used a cross-sectional design. We used the Self-Care of Chronic Illness Inventory and the Caregiver Contribution to Self-Care of Chronic Illness Inventory, which measure patient self-care and informal caregivers' contribution to self-care maintenance, monitoring and management. Exploratory Structural Equation Modeling was performed to verify the existence of dyadic latent constructs in each scale in patients and informal caregivers.

RESULTS

A convenience sample of 493 patients and informal caregivers, with a mean age of 76.47 and 52.76 years, respectively, was studied. In the self-care maintenance scales, 2 correlated factors (r = 0.34, P < .001) were identified, indicating the presence of a dyadic second-order construct. In addition, 2 factors that were not correlated (r = 0.11, P = .064) were identified in the self-care monitoring scales, indicating the absence of a dyadic construct. Finally, we found a 3-factor model in the self-care management scales composed of both patient and caregiver items, indicating a dyadic first-order construct.

CONCLUSIONS

Knowing which care behaviors are dyadic in chronic conditions is important for tailoring interventions to improve self-care. Self-care maintenance and management would benefit from dyadic interventions, while self-care monitoring would not. The results of this study may illuminate future theoretical and scientific developments in dyadic care of chronic illness.

Validity and Reliability of the Korean Version of the Revised Self-Care of Heart Failure Index v7.2

The psychometric properties of the Korean version of the revised Self-Care of Heart Failure Index (SCHFI) remain undetermined; therefore, we aimed to evaluate the construct and convergent validity and reliability of the Korean version of the SCHFI in Korean patients with heart failure (HF). Using a cross-sectional design, 207 patients with HF provided data on self-care and self-efficacy in self-care for this psychometric testing. The confirmatory factor analysis supported the construct validity of the Korean version with a three-factor structure: Self-Care Maintenance, Symptom Perception, and Self-Care Management. Convergent validity was supported by the significant relationships between self-efficacy and each scale of the Korean version of the SCHFI (r = .425-.549, p < .001). The reliability estimates were marginally adequate, with a Cronbach's alpha of .655 to .776, McDonald's omega of .710 to .836, and composite reliability coefficients of .704 to .834. The SCHFI was supported as a valid and reliable measure of self-care for Koreans with HF. However, the marginal levels of the Cronbach's alpha coefficients still require validation in a larger sample.

Predictors of Self-care Among Chinese Patients With Chronic Heart Failure

BACKGROUND

Self-care is important for improving the health outcomes of individuals with chronic heart failure (CHF). However, predictors of self-care behaviors remain unclear in Chinese society.

OBJECTIVE

The aims of this study were to explore predictors of self-care in Chinese patients with CHF and clarify the complex relationships between predictors and self-care behaviors guided by the Situation-Specific Theory of Heart Failure Self-Care.

METHODS

A cross-sectional study was conducted among individuals hospitalized with CHF in China. Person, problem, and environmental factors pertaining to self-care were collected by a questionnaire survey. Self-care was assessed by the Self-Care of Heart Failure Index version 6. Direct and indirect relationships between factors and self-care behaviors and the mediating role of self-care confidence were analyzed by the structural equation model.

RESULTS

In total, 204 participants were involved in this study. The Situation-Specific Theory of Heart Failure Self-Care model demonstrated a good fit (root mean square error of approximation, 0.046; goodness of fit index, 0.966; normed fit index, 0.914; comparative fit index, 0.971). Inadequate self-care capabilities were common among Chinese patients with CHF. Person-related factors (female gender, higher monthly income and educational level), problem-related factors (severe New York Heart Association function class and better instrumental activities of daily living), and environmental factors (better social support and living in more developed areas) were significant predictors of better self-care behaviors ( P < .05). These associations were partly or fully mediated by self-care confidence.

CONCLUSION

The Situation-Specific Theory of Heart Failure Self-Care can be used to guide research and practice in patients with CHF. Interventions and policies on promoting self-care in Chinese population living with CHF are encouraged, particularly for underserved populations.

Using Mobile Integrated Health and telehealth to support transitions of care among patients with heart failure (MIGHTy-Heart): protocol for a pragmatic randomised controlled trial

INTRODUCTION

Nearly one-quarter of patients discharged from the hospital with heart failure (HF) are readmitted within 30 days, placing a significant burden on patients, families and health systems. The objective of the 'Using Mobile Integrated Health and Telehealth to support transitions of care among patients with Heart failure' (MIGHTy-Heart) study is to compare the effectiveness of two postdischarge interventions on healthcare utilisation, patient-reported outcomes and healthcare quality among patients with HF.

METHODS AND ANALYSIS

The MIGHTy-Heart study is a pragmatic comparative effectiveness trial comparing two interventions demonstrated to improve the hospital to home transition for patients with HF: mobile integrated health (MIH) and transitions of care coordinators (TOCC). The MIH intervention bundles home visits from a community paramedic (CP) with telehealth video visits by emergency medicine physicians to support the management of acute symptoms and postdischarge care coordination. The TOCC intervention consists of follow-up phone calls from a registered nurse within 48-72 hours of discharge to assess a patient's clinical status, identify unmet clinical and social needs and reinforce patient education (eg, medication adherence and lifestyle changes). MIGHTy-Heart is enrolling and randomising (1:1) 2100 patients with HF who are discharged to home following a hospitalisation in two New York City (NY, USA) academic health systems. The coprimary study outcomes are all-cause 30-day hospital readmissions and quality of life measured with the Kansas City Cardiomyopathy Questionnaire 30 days after hospital discharge. The secondary endpoints are days at home, preventable emergency department visits, unplanned hospital admissions and patient-reported symptoms. Data sources for the study outcomes include patient surveys, electronic health records and claims submitted to Medicare and Medicaid.

ETHICS AND DISSEMINATION

All participants provide written or verbal informed consent prior to randomisation in English, Spanish, French, Mandarin or Russian. Study findings are being disseminated to scientific audiences through peer-reviewed publications and presentations at national and international conferences. This study has been approved by: Biomedical Research Alliance of New York (BRANY #20-08-329-380), Weill Cornell Medicine Institutional Review Board (20-08022605) and Mt. Sinai Institutional Review Board (20-01901).

Follow up from the Lebanese Heart Failure Snapshot: Reflection of geopolitical instability

BACKGROUND

Heart failure has a great cost on the health care system. The readmission and mortality rates and their predictors are greatly affected by political and sociocultural unrests.

AIMS

To determine the readmission and mortality rates and their predictors in heart failure population in times of political and sociocultural unrests.

DESIGN

A cross-sectional follow-up with patients recruited for the Lebanese Heart Failure Snapshot was conducted over the month of June in 2019.

METHODS

Phone calls were conducted at 30-90 days, 6-12 months following hospital discharge for patient previously admitted to one of the study hospitals for heart failure exacerbation. Follow-up data was conducted from July 2019 till May 2020.

FINDINGS

The mean age of the 120 participants was 71 years with a mean ejection fraction of 41%. The 30-90 days, 6-12 months readmission rates were 20%, 56%, 75%, and 78%, respectively. Readmission predictors were non-sinus rhythm and low diastolic blood pressure at admission. Mortality rates at 30-90 days, 6-12 months were 7%, 11%, 17%, and 28%, respectively. Low diastolic blood pressure and longer length of hospital stay were associated with mortality.

CONCLUSION

The rapid changes in the country make it difficult to formulate an intervention plan. This was seen in the increased rates of readmission and the decreased rates of mortality. Rigorous research should be conducted at every phase of the sociocultural changes in developing countries that were hit by the COVID-19 pandemic and had their economy largely affected.

IMPACT

The occurrences of the countries can greatly influence the outcomes of patients with heart failure. This is true in developing countries that were affected by the COVID-19 pandemic socially, economically, and politically. Research should be done regularly to establish the effect of these changes on patients with heart failure. Nevertheless, nursing roles are the common denominator that should be adapted to all the changes and provided despite all challenges to assure improved outcomes. Such practices include discharge education tailored to the subjective needs of the patients and continuous, uninterrupted follow-up despite of all the occurrences. These practices are likely to decrease adverse outcomes in patients with heart failure.

Psychometric Evaluation of the Self-Care in Chronic Obstructive Pulmonary Disease Inventory in the United States

BACKGROUND

High quality self-care among individuals with chronic obstructive pulmonary disease (COPD) promotes better outcomes, however, there are few validated self-care measures that are psychometrically sound to be used in research.

OBJECTIVES

The purpose of this study is to examine the psychometric properties of the Self-Care in Chronic Obstructive Pulmonary Disease Inventory (SC-COPDI) in an English-speaking population in the United States.

METHODS

Factorial validity, construct validity and reliability of the SCCOPDI were examined using components analysis via principal components analysis, hypothesis testing via multivariate linear regression, Cronbach's alpha, and split-half reliability.

RESULTS

The SCCOPDI demonstrated strong evidence of validity and reliability on par with the SCCOPDI's original construction. Component analysis produced item loadings consistent with the theoretical underpinnings of the instrument. Reliability metrics yielded good internal consistency across all subscales of the SCCOPDI.

CONCLUSIONS

The SCCOPDI is a valid and reliable instrument to measure self-care in people with COPD.

Influence of mutuality on quality of life in heart failure patient with inadequate self-care and caregiver dyads: an actor-partner interdependence model analysis

AIMS

Mutuality, a positive quality of the relationship between patients and their informal caregivers characterized by love and affection, shared pleasurable activities, shared values, and reciprocity, influences several patient-caregiver outcomes in chronic-condition cases, but it remains unknown whether it influences the heart failure (HF) patient-caregiver dyad quality of life (QOL). The aim of this study was to evaluate the influence of mutuality and its four dimensions (love and affection, shared pleasurable activities, shared values, and reciprocity) on QOL in HF patient-caregiver dyads.

METHODS AND RESULTS

Cross-sectional study: Using the actor-partner interdependence model, we examined how an individual's mutuality influenced his/her own QOL (actor effect) and his/her partner's QOL (partner effect). Mutuality and physical and mental QOL were measured with the Mutuality Scale and Short Form 12, respectively. A total of 494 HF patient-caregiver dyads were enrolled in the study. Mutuality showed strong evidence of caregiver partner effects on the HF patients' physical QOL (total score B = 2.503, P = 0.001; shared pleasurable activities B = 2.265, P < 0.001; shared values B = 1.174, P = 0.420 and reciprocity B = 1.888, P = 0.001). For the mental QOL, mutuality and its four subscales had actor effects only on the patients' mental health (total mutuality B = 2.646, P = 0.003; love and affection B = 1.599, P = 0.360; shared pleasurable activities B = 2.599, P = 0.001; shared values B = 1.564, P = 0.001 and reciprocity B = 1.739, P = 0.020). In caregivers, mutuality had an actor effects on mental QOL (total score B = 1.548, P = 0.041 and reciprocity B = 1.526, P = 0.009).

CONCLUSION

Our results confirm the important role of mutuality in determining the physical and mental QOL in HF patient-caregiver dyads. Interventions aimed at improving the relationships within HF patient-caregiver dyads may have an impact on HF patients' and caregivers' QOL.

SYMPERHEART: an intervention to support symptom perception in persons with heart failure and their informal caregiver: a feasibility quasi-experimental study protocol

INTRODUCTION

Symptom perception in heart failure (HF) has been identified as crucial for effective self-care, and is related to patient and health system outcomes. There is uncertainty regarding the feasibility and acceptability of symptom perception support and doubts regarding how to include informal caregivers. This study aims to test the feasibility, acceptability and outcome responsiveness of an intervention supporting symptom perception in persons with HF and their informal caregiver.

METHODS AND ANALYSIS

A feasibility study with a quasi-experimental pretest and post-test single group design is conducted. The convenience sample consists of 30 persons with HF, their informal caregivers and six nurses. SYMPERHEART is an evidence-informed intervention that targets symptom perception by educational and support components. Feasibility is measured by time-to-recruit; time-to-deliver; eligibility rate; intervention delivery fidelity rate. Acceptability is measured by rate of consent, retention rate, treatment acceptability and the engagement in the intervention components. Outcome responsiveness includes: HF self-care (via the Self-care of Heart Failure Index V.7.2); perception of HF symptom burden (via the Heart Failure Somatic Perception Scale V.3); health status (via the Kansas City Cardiomyopathy Questionnaire-12); caregivers' contribution to HF self-care (via the Caregiver Contribution to Self-Care of Heart Failure Index 2); caregivers' burden (via the Zarit Burden Interview). Clinical outcomes include HF events, hospitalisation reason and length of hospital stay. Descriptive statistics will be used to report feasibility, acceptability, patient-reported outcomes (PRO) and clinical outcomes. PRO and caregiver-reported outcome responsiveness will be reported with mean absolute change and effect sizes.

ETHICS AND DISSEMINATION

The study is conducted according to the Declaration of Helsinki. The Human Research Ethics Committee of the Canton of Vaud, Switzerland, has approved the study. Written informed consent from persons with HF and informal caregivers are obtained. Results will be published via peer reviewed and professional journals, and further disseminated via congresses.
