title: Translation, adaptation and validation of the Coronary Revascularization Outcome Questionnaire into Greek.
abstract: OBJECTIVE
  Evaluating the impact of coronary revascularization on patients' health related quality of life with a patient-based and disease-specific tool is important for drawing conclusions about treatment and outcomes. This study reports on the translation, adaptation and psychometric evaluation of a Greek version of the Coronary Revascularization Outcome Questionnaire (CROQ-Gr).
  
  
  METHODS
  A total of 609 (81.7% male) patients who had undergone coronary revascularization (percutaneous coronary intervention or coronary artery bypass grafting) were recruited from four hospitals in Athens. After translating the CROQ into Greek, a preliminary qualitative study and a pilot quantitative study were conducted. A full psychometric evaluation was carried out on the main study's data.
  
  
  RESULTS
  The psychometric evaluation demonstrated that the CROQ-Gr is acceptable to patients (high response rate, low missing data) and has a good level of reliability (internal consistency >0.70, test-retest reliability >0.90) and validity (both content and construct validity).
  
  
  CONCLUSIONS
  The results of this study show the CROQ-Gr to be a psychometrically rigorous patient-based measure of outcomes of coronary revascularization. It would be appropriate for use in evaluative research as well as a routine clinical tool to aid cardiologists in monitoring the outcomes of care.
