Structured PICO
P
Population
659 Italian adults with HF, confirmed by echocardiography and clinical evidence, age >18, medically stable (no acute coronary event in last 3 months). Mean age 72.63, 57.1% male.
I
Intervention
Administration of the Italian version of the Self-Care of Heart Failure Index version 6.2 (SCHFI v.6.2)
O
Outcome
Construct validity (using confirmatory and exploratory factor analysis), contrasting groups validity, internal consistency, and test-retest reliability of the SCHFI v.6.2patient reported
The Italian version of the SCHFI v.6.2 demonstrated excellent construct validity, internal consistency, and test-retest reliability when its three scales were analyzed individually, supporting its use in clinical practice and research.
Limitations
- Completed in a country different from where the SCHFI was originally developed
- Test-retest reliability might have been influenced by the learning effect caused by the first administration
Cite This Study
Vellone et al. (2013) conducted a cross-sectional in Heart failure (n=659). Self-Care of Heart Failure Index Version 6.2 (SCHFI v.6.2) was evaluated on Construct validity (Confirmatory Factor Analysis fit indices). Psychometric testing of the Self-Care of Heart Failure Index Version 6.2 demonstrated excellent construct validity for individual scales when analyzed separately, supporting its clinical use.
