Aims. To evaluate internal consistency and test–retest reliability of the Iranian version of the Angina Pectoris characteristics questionnaire.
Background. To evaluate symptoms in patients with Angina Pectoris, the Iranian version of the Angina Pectoris characteristics questionnaire was created by combining items from Modified Rose Questionnaire, Short Form-McGill Questionnaire and the Accompanying Symptom Checklist. The Angina Pectoris characteristics questionnaire has been developed and validated recently although it required assessment of its reliability.
Design. Reliability study using test and retest.
Method. One hundred and ten coronary heart disease patients with Angina Pectoris were included. The test–retest reliability of the instrument was estimated for measurement after 15 days.
Result. The analysis of the result indicated that internal consistency was found adequate at both assessments (Cronbach’s alpha = 0·65) for test and retest. There was no significant difference between test and retest. The intra-class correlation coefficient ranged from 0·76–0·98.
Conclusion. The Angina Pectoris characteristics questionnaire is a reliable instrument for the assessment of Angina Pectoris characteristics in a Persian population.
Relevance to clinical practice. The Angina Pectoris characteristics questionnaire can be used with confidence in Iranian coronary heart disease patients for Assessing Angina Pectoris symptom.
