Test for Respiratory and Asthma Control in Kids (TRACK): validation of the Portuguese version

ConclusionWe have demonstrated that the Portuguese version of the TRACK questionnaire has satisfactory reliability (internal consistency), adequate criterion validity (compared against GINA levels of control) and constructive validity (compared against respiratory symptoms and medical opinion), showing that it can be a useful tool to discriminate among children with different levels of respiratory symptom control.Trial registrationClinicalTrials.gov:NCT03290222.
