Objective: To develop, pilot test and psychometrically validate a shorter version of the coronary artery disease education questionnaire (CADE-Q), called CADE-Q SV. Methods: Based on previous versions of the CADE-Q, cardiac rehabilitation (CR) experts developed 20 items divided into 5 knowledge domains to comprise the first version of the CADE-Q SV. To establish content validity, they were reviewed by an expert panel (N = 12). Refined items were pilot-tested in 20 patients, in which clarity was provided. A final version was generated and psychometrically-tested in 132CR patients. Test-retest reliability was assessed via the intraclass correlation coefficient (ICC), the internal consistency using Cronbach's alpha, and criterion validity with regard to patients' education and duration in CR. Results: All ICC coefficients meet the minimum recommended standard. All domains were considered internally consistent (alpha > 0.7). Criterion validity was supported by significant differences in mean scores by educational level (p < 0.01) and duration in CR (p < 0.05). Knowledge about exercise and nutrition was higher than knowledge about medical condition. Conclusion: The CADE-Q SV was demonstrated to have good reliability and validity. Practice Implications: This is a short, quick and appropriate tool for application in clinical and research settings, assessing patients' knowledge during CR and as part of education programming.
