The Modified British Medical Research Council Questionnaire is considered an adequate and simple measure of breathlessness in chronic obstructive pulmonary disease. It is widely used in clinical practice in Portugal, but it still lacks confirmatory evaluation for the Portuguese setting. The aim of this study was to perform a cultural adaptation and validation of the Modified British Medical Research Council Questionnaire so that its most suitable version can be made available to researchers and clinicians in Portugal.
