Validity and Reliability of the Turkish Version of the European Heart Failure Self-Care Behaviour Scale (Ehfscb-9).

To adapt the 9-Item European Heart Failure Self-Care Behaviour Scale to Turkish. A methodological design was used in this study. The study population consists of 120 patients that accepted to participate in this study and who had a heart failure. Firstly, the language validity of the scale was addressed. In the following step, for content validity, experts' views were obtained and the scale was revised accordingly. The construct validity was evaluated through factor analysis. As for reliability, it was determined using "test-retest reliability", "cronbach alpha method", "item total score correlation technique" and "scale alpha if item deleted". The 9-Item European Heart Failure Self-Care Behaviour Scale was translated into Turkish for language validity. For content validity, Kendall Goodness-of-fit Correlation Test was performed (W=0.29; p>0.05). The factor analysis revealed that the scale items were gathered under two factors, which explained 50.39% of the total variance, and the factor loadings ranged between 0.21-0.92. Test-retest reliability showed significant agreement for the total score (ICC: 0.84, 95%CI: 0.67-0.92). The item total correlation ranged from 0.10 to 0.80. Internal consistency was satisfactory with a Cronbach's alpha coefficient of 0.80. The 9-Item European Heart Failure Self-Care Behaviour Scale is deemed a valid and reliable scale in holistically assessing heart failure-specific selfcare in Turkish patients.
