ABSTRACT

Objective:

to carry out translation, cross-cultural adaptation to Portuguese and assess the reliability of the four versions of the Coronary Revascularization Outcome Questionnaire - adapted.

Methods:

a methodological study of translation and cross-cultural adaptation into Portuguese, as proposed by Beaton et al., and reliability analysis, by calculating Cronbach's alpha coefficient and item-total correlation of the four versions of the Coronary Revascularization Outcome Questionnaire - adapted.

Results:

the adaptations made facilitated the understanding of the items. All domains had Cronbach's alpha above 0.70, except two in the post-percutaneous coronary intervention version and two in the post-myocardial surgical revascularization version. All items had item-total correlation values greater than 0.20, except two in the post-percutaneous coronary intervention version, one in the pre-coronary intervention version and six in the post-myocardial surgical revascularization version.

Conclusion:

the cross-cultural adaptation to Portuguese was considered satisfactory. Pre-procedure versions were considered reliable, while the post-procedures require other psychometric analyses.
