Arabic Version of the Caregiver Contribution to Self-Care of Heart Failure Index v2: A Psychometric Evaluation

Accurate assessment of caregivers' roles in self-care for heart failure (HF) is essential for effectively managing the condition. This evaluation helps identify areas needing additional support, allowing healthcare providers to create tailored and effective patient care strategies.

The objective of this study is to test the validity and reliability of the Arabic version of The Caregiver Contribution to Self-Care of Heart Failure Index Version 2 (CC-SCHFI v2) among the caregivers of patients with HF in Jordan.

A cross-sectional design was used to test the validity and reliability of the Arabic version of CC-SCHFI v2. A translation process and psychometric evaluation were performed. Three hundred caregivers and 300 patients with HF were statistically analyzed.

Caregivers had a mean age of 42 years (females were dominant), whereas patients had a mean age of 66 years. Statistical analysis showed significant results: content validity showed high content validity index (0.92), construct validity showed that Bartlett test ( P  < .001) confirmed factorability, and the Kaiser-Meyer-Olkin index was 0.74. Confirmatory factor analysis indicated a good fit (χ 2  = 150.23, df  = 90, P  < .001; comparative fit index = 0.95, TLI = 0.94, root mean square error of approximation = 0.045), revealing a 3-factor solution that accounted for 75% of the total variance, 50% for self-care maintenance, 15% for symptom perception, and 10% for self-care management. Concurrent validity showed a strong correlation ( r  = 0.68, P  < .001) between the CC-SCHFI v2 and SCHFI scales. Reliability was good internal consistency, with Cronbach α between 0.78 and 0.84, and the test-retest showed intraclass correlation coefficients from 0.85 to 0.90.

This study provides valuable evidence supporting the reliability and validity of the Arabic version of the CC-SCHFI v2 among the caregivers of patients with HF in Jordan.
