Background
The long-term success of cardiac rehabilitation programs rests in part on the patient’s ability to maintain health behaviors, which is influence by the patient education received. Therefore, a short and reliable tool to assess patients' knowledge is warranted. The aim of this study was to translate, culturally-adapt and psychometrically validate the French-Canadian version of the Coronary Artery Disease Education Questionnaire Short Version (CADE-Q SV).
Methods
The French CADE-Q SV – translated and culturally-adapted - was reviewed by 3 bilingual experts in cardiovascular disease. This version was then psychometrically tested in 115 CR patients in two Canadian provinces (Québec and New Brunswick). The questionnaire was completed at patients’ first CR session and in the end of their 6-month program to assess interpretability. The internal consistency was assessed using Kuder-Richardson-20 (KR-20) and Cronbach's alpha, factor structure using confirmatory factor analysis, and criterion validity regarding level of education and family income.
Results
KR-20 was 0.72. Factor analysis revealed 5 factors, all internally consistent. Criterion validity was supported by significant differences in total scores by educational level and family income (p < 0.05). Results showed that increases in knowledge can moderately increase mean steps per day and peakVO2, with an MCID of 3.00. The overall mean was 15.7 ± 2.0. The area with the highest knowledge was risk factors and the lowest was psychosocial risk.
Conclusion
The French-Canadian CADE-SV was demonstrated to have good validity and reliability.
