Background and Aim: The quality of life is a major goal in the context of preventive and therapeutic cardiology. Up to now, there wasn’t any validated instrument for patient based outcome measurement, before and after CABG and PTCA procedures, in Iran. In this study, we have translated and evaluated the reliability of the Persian version of coronary revascularization outcome questionnaire (CROQ). The reliability of the Persian version of coronary revascularization outcome questionnaire was not known. We therefore aimed to assess the test-retest reliability and scale internal consistency of the instrument in two groups of patients undergoing CABG and PTCA procedures.
Method: This is a methodological study, and was conducted for the aim of: the Psychometric study of the Persian version of coronary revascularization outcome questionnaire (CROQ). The study's population was 60 patients (30 CABG and 30 PTCA). This instrument has 4 versions (2 versions for CABG and 2 versions for PTCA). It has pre and post operation versions for each group of patients. The patients were assessed 3 months after operation, by the post operation version. For testing the instrument's reliability, the assessment was repeated 1-2 weeks later.
Results: Psychometric tests confirmed the reliability, internal consistency, construct validity and responsiveness of the Persian version of CROQ.
Conclusion: For clinical trials evaluation, we need to compare quality of life before and after interventions, by an instrument. Disease specific measures are more responsive in detecting treatment effects than general measurements, so for this group of patients, disease specific measurement is necessary. With concern for the Psychometric test results, we encourage the use of CROQ in patients undergoing CABG and PTCA procedures.
