Validation of the Brazilian-Portuguese version of the European Community Respiratory Health Survey in asthma patients.
BACKGROUND
The European Community Respiratory Health Survey (ECRHS) questionnaire was planned to answer questions about the distribution of asthma. Our objective was to determine the cultural equivalence of the ECRHS into the Brazilian-Portuguese language.


METHODS
We translated the ECRHS according to international criteria.


RESULTS
Small cultural adaptations were necessary. Among the 80 participating patients, the Cronbach indices were higher (0.98-1.00) and the Kappa indices varied from 0.77 to 1.00.


CONCLUSIONS
The study suggests that the Brazilian version of the ECRHS is conceptually equivalent to the original and similarly reliable and may be used in international studies involving Portuguese-speaking respiratory patients.
