Cross-Cultural Adaption and Psychometric Evaluation of Chinese Version of the Caregiver Contribution to Self-Care of Heart Failure Index.

To translate and adapt the English version of the Caregiver Contributions to Self-Care of Heart Failure Index (CC-SCHFI) to Chinese, and further to investigate the psychometric properties of the Chinese version of CC-SCHFI in a cohort of caregivers of people with heart failure. CC-SCHFI translation and cross-cultural adaption were performed. 240 caregivers were recruited to complete the instrument. The internal construct reliability was evaluated by Cronbach's α and item-to-total correlations. The concurrent validity was tested by using the CACHS which also measures caregivers' contribution to HF self-care. Psychometric analysis was performed with confirmatory factor analysis (CFA). We evaluated 4-factor structure for caregiver contribution to self-care maintenance scale, 1-factor structure for caregiver contribution to self-care management scale and 2-factor structure for confidence in contributing to self-care scale. All the subjects successfully completed the interviews in an average of 12.3 ± 3.2 min. The internal consistency reliability analysis of the CC-SCHFI showed Cronbach α of 0.83. All items showed adequate discrimination, with the item-total correlation coefficient of greater than 0.4. The scores of CC-SCHFI scales were significantly correlated with the CACHS scale scores. The correlation coefficients ranged from 0.341 to 0.765, indicating acceptable concurrent validity. For CFA, all factor loadings were significant at > 0.30 and generally medium to high. The simplified Chinese version of CC-SCHFI is a psychometrically reliable instrument with empirically supported validity, which can be applied to clinical evaluation of the contribution of caregivers to HF self-care. Compared with CACHS, CC-SCHFI can be more easily completed and simultaneously maintains acceptable concurrent validity. Further studies are warranted to investigate the combined use of these two instruments among other populations.

A psychometric evaluation of the Caregiver Contribution to Self-Care of Heart Failure Index in a Thai population.

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. 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. 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). 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.
