DOI: 10.5935/abc.20180258 In the last ten to fifteen years, we are seen more and more concern with patients ́ awareness about their diseases.1-3 Campaigns have been brought to the public to teach them about symptoms and signs that might bring concern and make them ask for help and go to an emergency room or, in the United States to call 911. This is true especially for patients with coronary artery disease (CAD), given the possibility of better quality of life and in some cases even a better prognosis of the disease in respect to morbidity and mortality. Beside this kind of campaigns, recently others started to aware people already with a diagnosis of CAD to the symptoms that may alert them of a problem and the consciousness about all medicines that modify the course of the disease and ways of life that are proved to contribute to this amelioration, as is physical activity.4-8 In this issue, dos Santos et al.9 did validate a questionnaire to evaluate patients with CAD and on cardiovascular rehabilitation (rehab) programs in order to assess their knowledge about their own disease. Interestingly they first validate a previous (CADE-Q) questionnaire in Portuguese, then validated an English translated version. After that, they do construct a CAD-Q II questionnaire, but in English. The motivation to do this second version was that some questions should be better structured to the understanding of the patients and a psychosocial approach might be a part of it. After publishing it in the English language then they decide to translate to the Portuguese language. It is really a different approach going from one language to another and coming back to the first one, what is not usually done. The need for implementing the CADE-Q with other components was based on cardiac rehabilitation programs focused on patients with CAD. The objective of this paper is to validate the English version of CAD-Q II. The job was done according to the available tests used to validate questionnaires from one language to other, using Cronbach's alpha test. What they found called attention, although already known from other studies with questionnaires.
