Background: Development of simple instruments for determination of self-care levels in heart failure (HF) patients is a subject of ongoing research. One such instrument, gaining growing popularity worldwide, is the European Heart Failure Self-care Behavior Scale (EHFScBS). The aim of this study was to adapt and to test reliability of the Polish version of EHFScBS.
Method: A standard guideline was used for translation and cultural adaptation of the English version of EHFScBS into Polish. The study included 100 Polish HF patients aged between 24 and 91 years, among them 67 men and 33 women. Cronbach’s alpha was used for analysis of the internal consistency of EHFScBS.
Results: Mean total self-care score in the study group was 34.2±8.1 points. Good or satisfactory level of self-care were documented in four out of 12 analyzed EHFScBS domains. Cronbach’s alpha for the entire questionnaire was 0.64. The value of Cronbach’s alpha after deletion of specific items ranged from 0.55 to 0.65.
Conclusion: Polish HF patients present significant deficits of self-care, which are to a large extent associated with inefficacy of the public health care system. Apart from cultural characteristics, the socioeconomic context of the target population should be considered during language adaptation of EHFScBS, as well as during interpretation of data obtained with this instrument. A number of self-care–related behaviors may be optimized as a result of appropriate educational activities, also those offered by nursing personnel.
