| Summary: | Aim. To assess the validity and psychometric properties of the Russian version of the Self-Care of Coronary Heart Disease Inventory (SC-CHDI) in patients with chronic coronary syndromes (CCS).Material and methods. The study was performed on 100 patients with stable coronary artery disease, who were sequentially admitted to the cardiology departments in December 2019. All patients admitted to the clinic underwent standard examination and treatment for patients with CCS. We have also evaluated socio-demographic properties (family status, educational level, profession, disability, income), quality of life (using questionnaires SF-36 and SAQ), levels of anxiety and depression (HADS), type D personality (DS-14 questionnaire), medication adherence (four-item Morisky-Green Medication Adherence Scale), Charlson comorbidity index. Self-care skills were assessed with the Self Care of Coronary Heart Disease Inventory.Results. Test-retest reliability of the questionnaire scales ranged from 0,79 to 0,85, while Cronbach's alpha varied from 0,738 for the entire questionnaire and from 0,649 to 0,716 for each of the scales, which indicates its sufficient reliability. The confirmatory factor analysis confirmed the correspondence of the obtained model to the experimental one. The criterion-related validity revealed correlation between the scales with the SF-36 physical functioning scale (r=-0,212, p<0,05), Charlson comorbidity index (r=0,282, p<0,01), physical activity restriction (r=-0,218, p<0,05) and the frequency of angina episodes (r=-0,340, p<0,05) of the SAQ questionnaire, duration of CCS (r=0,354, p<0,01) and Morisky-Green scale value (r=0,25, p<0,05).Conclusion. The Russian-language version of the Self-Care of Coronary Heart Disease Inventory showed sufficient psychometric properties and is a valid tool for assessing the self-care skills in patients with CCS. |
