Psychometric Validation of the Spanish Version of the Caregiver Contribution to Self-Care of Heart Failure Index ( CC-SCHFI)

Type of funding sources: None.

The Caregiver Contribution to Self-Care of Heart Failure Index (CC-SCHFI) is a theoretically driven instrument to measure the extent to which caregivers support Heart Failure ( HF) patients to perform self-care. The CC-SCHFI measures caregivers' contribution to the self-care maintenance and self-care management and caregiver confidence in contributing to heart failure patients, self-care. To date, the CC-SCHFI was never tested in Spanish speaking populations.

To translate the CC-SCHFI from English into Spanish and to test its psychometric characteristics.

CC-SCHFI translation and back-translation was performed according to the Beaton el al. Methodology. Data from a cross-sectional study conducted in an outpatient clinic in Spain were used for the analysis. Psychometric analysis was performed with Exploratory factor analysis (EFA) with oblique rotation. Cronbach’s alpha coefficient was used to test CC-SCHFI reliability.

Caregivers had a mean age of 60,5 and the majority was female (85%) Data from 220 caregivers were analyzed. From EFA, using the principal axis factoring method, we extracted two factors in self-care maintenance subscale ("treatment adherence behaviors" and "symptom control and maintenance behaviors" factors) and self-care monitoring subscale ("Illness behaviors" and "Prevention behaviors" factors) and one factor for self-efficacy subscale. The Cronbach’s alpha coefficient was = 0.838)
