Abstract
BackgroundCaregivers 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.MethodsThe 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.ResultsThe 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).ConclusionsThe 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.
Highlights
Caregivers are major contributor to the self-care of patients with heart failure
This includes acknowledging the vital role family members play as informal caregivers of patients with heart failure in Thailand [7], a rapidly rising elderly population, and the burden imposed on caregivers [8, 9]
Similar to a previous study [26], we evaluated the following fit indices and criteria [33,34,35,36,37,38,39]: the comparative fit index (CFI), goodness of fit index (GFI), adjusted goodness of fit index (AGFI), incremental fit index (IFI); normed fit index (NFI), root mean square error of approximation (RMSEA), root mean square residual (RMSR)
Summary
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. As the burden of heart failure increases in Thailand and other emerging economies, developing culturally appropriate, affordable and acceptable models is necessary [6] This includes acknowledging the vital role family members play as informal caregivers of patients with heart failure in Thailand [7], a rapidly rising elderly population, and the burden imposed on caregivers [8, 9]. Such models are likely to be characterized by a systematic, coordinated and integrated approach to individual (patient/caregiver) assessment and intervention, ideally in the home or local community centre, but with access to specialist expertise at the local hospital or clinic. Important is health care organized and delivered by competent, credentialed professionals with access to evidence-based guidelines and treatments [6, 10]
