Research aimed at evaluating Angina Pectoris (AP) symptoms in patients with Coronary Heart Disease (CHD) requires a comprehensive assessment tool applicable to this population. Because no single existing measure assessed the full range of symptom characteristics important to our study, we combined two measures (the modified Rose Questionnaire (MRQ), and the Short Form-McGill Pain Questionnaire (SF-MPQ) and added one item to examine specific aspects of AP symptoms (Accompanying Symptom Checklist). The purposes of this study are: (i) to describe the process of translating the SF-MPQ, MRQ and accompanying symptom checklist from English to the Farsi language; and (ii) to evaluate substantial psychometric works (content and construct validity) for the entire instrument and each part of it (SF-MPQ, MRQ and accompanying symptom checklist). A cross-cultural adaptation of the instrument was carried out before developing the final version of it. To these ends, one hundred and 10 CHD patients with AP were assessed by this hybrid measure in an initial study. An analysis of the results indicated that a content valid instrument had been developed. There was a significantly high correlation between scores in the SF-MPQ and there were associations between items in the MRQ. The Iranian version of AP characteristics questionnaire is valid; it is capable of describing characteristics of AP symptoms. However, the reliability of the instrument needs to be assessed through further research.
