“…For SEM, again this varies, with rules of thumb of 10 cases/observations per indicator variable in setting a lower bound of an adequate sample size, though the ratio can be as low as 5 to 1 [ 43 ]. Finally, shortly after commencing this study, a revised version of the CC-SCHFI [ 22 ] was published, and a translation and psychometric evaluation of this is warranted.…”

“…In Western countries a number of instruments have been developed to measure caregiver contribution to heart failure self-care, including the Caregiver Contribution to Heart Failure Self-Care (CACHS) instrument [ 18 ], the Heart Failure Caregiver Questionnaire (HF-CQ) [ 19 ], the Caregiver Burden Questionnaire Heart Failure (CBQHF) [ 20 ] and the Caregiver Contribution to Self-Care to Heart Failure Index (CC-SCHFI) [ 21 ], recently revised [ 22 ], which is derived from the Self-Care of Heart Failure Index (SCHFI) [ 23 ] and has adequate reliability (Cronbach α > 0.80).…”

Background Caregivers are major contributor to the self-care of patients with heart failure. The Caregiver Contribution to Self-Care of Heart Failure Index (CC-SCHFI) measures these contributions across three scales: self-care maintenance (symptom monitoring and treatment adherence); self-care management (dealing with symptoms); and confidence in contributing to the self-care (self-efficacy in managing self-care) of patients with heart failure. Informal caregivers play a vital role in supporting family members with heart failure in Thailand, yet no validated tool exists to measure their contribution. We examined the psychometric properties of the CC-SCHFI in a Thai population. Methods The CC-SCHFI was translated into Thai using a standard forward and backward translation procedure. A cross-sectional design was used to examine the psychometric properties of the Thai version of the CC-SCHFI in 100 family caregivers of heart failure patients in Southern Thailand. Confirmatory factor analysis was used to assess construct validity, and factor score determinacy coefficients were computed to evaluate internal consistency reliability. Results The Thai version of the CC-SCHFI demonstrated acceptable internal consistency (composite reliability of each scale ranged from 0.76 to 0.99). Reliability estimates were adequate for each scale (McDonald’s omega ranged from 0.75 to 0.96). Confirmatory factor analysis supported the original factor structure of the instrument, with good fit indices for all three scales (comparative fit index = 0.98–1.00; root-mean-square error of approximation = 0.00–0.07). Conclusions The Thai version of the CC-SCHFI appears to be a valid and reliable instrument for measuring caregiver contributions to self-care maintenance and self-care management as well as contributing to caregiver confidence in the self-care of Thai heart failure patients.

“…In prior studies (Barbaranelli et al, 2014; Vellone et al, 2013) we found a different factorial structure in the SCHFI v.6.2 between U.S. and European populations. Thus, anticipating a possible misfit of the U.S. SCHFI v.7.2 model, we considered the factorial structure of the Caregiver Contribution to Self‐Care of Heart Failure Index 2 (CC‐SCHFI 2; Vellone et al, 2020) as an alternative model for SCHFI v.7.2 testing. The CC‐SCHFI 2 is the caregiver version of the SCHFI v.7.2 already tested for validity and reliability in an Italian population.…”

“…However, despite its positive effects, self‐care is frequently found to be poor in patients with HF (Cocchieri et al, 2015; Seid et al, 2019). Poor self‐care may be associated with higher depression, lower self‐efficacy, older age, cognitive impairment, and poor sleep quality—all common in HF and all variables known to affect HF self‐care (Kessing et al, 2016; Ryou et al, 2020; Sedlar et al, 2017; Vellone et al, 2020). For these reasons, clinicians and researchers are actively studying ways to promote self‐care and need valid and reliable instruments for this effort.…”

Clinicians and researchers need valid and reliable instruments to evaluate heart failure (HF) self-care. The Self-Care of Heart Failure Index (SCHFI) is a theoretically driven instrument developed for this purpose. The SCHFI measures self-care with three scales: self-care maintenance, measuring behaviors to maintain HF stability; symptom perception, measuring monitoring behaviors; and self-care management, assessing the response to symptoms. After the theory underpinning the SCHFI was updated, the instrument was updated to version 7.2 but it was only tested in the United States. In this study we tested the psychometric characteristics (structural and construct validity, internal consistency, and test-retest reliability) of the SCHFI v.7.2 in an Italian population of HF patients. We used a cross-sectional design to study 280 HF patients with additional data collected after 2 weeks for test-retest reliability. Adults with HF (mean age 75.6 (±10.8); 70.8% in New York Heart Association [NYHA] classes II and III) were enrolled from six centers across Italy. Confirmatory factor analysis showed supportive structural validity in the three SCHFI v.7.2 scales (CFI from 0.94 to 0.95; RMSEA from 0.05 to 0.07). Internal consistency reliability estimated with Cronbach's α and composite reliability ranged between .73 and .88; test-retest reliability ranged between 0.73 and 0.92. Construct validity was supported with significant correlations between the SCHFI v.7.2 scale scores and quality of life, brain natriuretic peptide levels and NYHA class. This study further supports the psychometric characteristics of the SCHFI v.7.2, illustrating that it can be used in clinical practice and research also in an Italian population.

“…67 Clinical outcomes are HF events (ie, number of HF hospitalisations due to decompensation; number of deaths occurring during the 3 months study period); and length of stay in case of HF hospitalisation. Informal caregiverreported outcomes are caregivers' contribution to HF self-care measured with the CC-SCHFI 2 68 and caregivers' burden measured with the Zarit Burden Interview. 69 Both CC-SCHFI 2, SCHFI V.7.2 and HFSPS V.3 have been translated from English to French and German (for Switzerland) according to state-of the art recommendations for linguistic validation of PROs.…”

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

IntroductionSymptom 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 analysisA 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 disseminationThe 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.Trial registration numberISRCTN18151041.
