Background: The promotion of self-care in patients with heart failure (HF) is a promising strategy for maintaining health and preventing exacerbation of HF and a continuous need for healthcare services. To assess patient self-care, valid and reliable instruments are needed, but there is no psychometrically tested instrument for use in a German HF population.
Aim: The aim of this study was to determine the validity and reliability of the German version of the 9-item European Heart Failure Self-care Behaviour Scale (G9-EHFScBS). Construct validity including factor analysis and discriminant validity, concurrent validity, test–retest reliability and internal consistency were analysed.
Methods and results: The G9-EHFScBS was translated into German, and its validity and reliability were tested with 109 patients. The item-total correlation ranged from 0.09 to 0.63. Internal consistency was fair, with a Cronbach’s alpha of 0.71 (95%CI: 0.63 to 0.77). Test–retest reliability using an intra-class correlation coefficient showed substantial agreement for the entire scale (ICC: 0.69; 95%CI: 0.56 to 0.79). The G9-EHFScBS was able to distinguish patients with and without extra HF education at a statistically significant level (t = 2.105; p = 0.04). A factor analysis did not show the theoretical assumed dimensions of the scale.
Conclusion: The G9-EHFScBS is deemed a valid and reliable instrument to assess HF-specific self-care in a German HF population.
