Translation, Cross-Cultural Adaptation, and Psychometric Validation of the Russian Coronary Artery Disease Education Questionnaire II (CADE-Q II) in chronic coronary syndrome patients

Aim . This study sought to translate, cross-culturally adapt, and psychometrically validate the Coronary Artery Disease Education Questionnaire II (CADE-Q II) in Russian. Material and methods . Independent translations and back-translations of the CADE-Q II were conducted by bilingual health professionals and certified translators, respectively. Experts met to consider cultural relevance of the items to Russian patients. The finalized version was then pilot tested in a group of patients to assess understanding and time to complete the tool. Following these steps, 303 patients with a diagnosis of stable coronary artery disease treated in the Outpatient Cardiology Department between April and November 2021 completed the CADE-Q II. The following psychometric properties were evaluated: confirmatory factor analysis, internal consistency (assessed by Cronbach's alpha), test-retest reliability (ICC), and criterion validity (assessed through the association with CADE-Q II and The Self Care of Coronary Heart Disease Inventory and SF-36 scores, among other characteristics from the participants including educational level). Results . After items were translated, revised, culturally adapted and finalized, 30 patients took 30 minutes to complete the CADE-Q II during pilot test and questionnaire was considered understandable by all.
