    • Abstract:
      Background: According to evidence-based guidelines, adherence to blood pressure--lowering medication and lifestyle modifications is a crucial part of hypertension management. Self-care is an effective method for secondary prevention. However, patients continue to exhibit major deficits in terms of adherence, self-control, and self-care. Standardized instruments for the effective monitoring of patients' self-care abilities are still lacking. Objective: The objectives of this study were to produce a translation and cross-cultural adaptation of the Self-care of Hypertension Inventory (SC-HI) and to evaluate the psychometric properties of its Polish version. Methods: The scale underwent translation and psychometric assessment using the standard methodology (forward-backward translation, review, psychometric analysis, criterion validity). The study included 250 patients, with a mean age of 61.23 ± 14.34 years, treated in a hypertension clinic. Results: Mean self-care levels were evaluated in 3 domains: self-care maintenance (56.73 ± 18.57), self-care management (64.17 ± 21.18), and self-care confidence (62.47 ± 24.39). The Cronbach α for each domain showed satisfactory parameters: 0.755 for maintenance, 0.746 for management, and 0.892 for confidence. In the Polish version, the 3-factor structure of the SC-HI was not directly confirmed. Therefore, so-called modification indices were applied to obtain a standardized root mean square residual value less than 0.09 and a root mean square error of approximation value less than 0.06. Conclusions: The SC-HI has been successfully translated and adapted for Polish settings, and is suitable for application among patients with hypertension. [ABSTRACT FROM AUTHOR]
