Resumen

Objective: To validate the Spanish Coronary Artery Disease Education Questionnaire Short Version(CADE-QSV). Background: Knowledge assessment can tailor patient education strategies in CR. Methods: Ten CR experts culturally-adapted the translated tool and 249 CR patients in three countries participated in the psychometrically validation. The internal consistency was assessed using KR-20 and Cronbach's alpha. Distribution- and anchor-based methods were used to estimate the MCID for interpretability analysis. Factor structure, acceptability, floor and ceiling effects and discriminant validity were also assessed. Results: KR-20 was 0.75.Factor analysis revealed 5 factors, all internally consistent. Discriminant validity was supported by significant differences in educational level and family income at post-CR. Results showed that increases in knowledge can moderately increase mean steps per day, with MCID=3.00. Items were completed by 98% of participants. No evidence for ceiling/floor effects on total score. The area with the highest knowledge was nutrition and the lowest was medical condition. Conclusion: The Spanish CADE-QSV demonstrated preliminary validity and reliability.
