Cross-cultural reproducibility of the Brazilian Portuguese version of the role checklist for persons with chronic obstructive pulmonary disease

Abstract

OBJECTIVE. This article presents the results of a cross-cultural reproducibility and test–retest reliability study of a Brazilian version of the Role Checklist, in a population with chronic obstructive pulmonary disease (COPD). METHODS. The English version was translated and culturally adapted into Brazilian Portuguese, then administered twice at a 2-week interval to a group of 25 clinically stable individuals with COPD. RESULTS. Cross-cultural adaptation led to adjustments in some terms used in the checklist. Values obtained for kappa suggested moderate-to-substantial agreement for Part I and Part II. No statistically significant correlations were found between agreement and variables of gender, occupation, marital status, level of education, level of depression, or severity of bronchial obstruction. CONCLUSION. The Brazilian Portuguese version of the Role Checklist was found content valid and reliable for persons with COPD and probably for the Brazilian population in general.
