Welcome to the COPD Assessment Test website for healthcare professionals/researchers.
The COPD Assessment Test (CAT) is a questionnaire for people with COPD. It is designed to measure the impact of COPD on a person's life, and how this changes over time. The CAT is simple to administer, and aims to help clinicians, with their patients, better manage COPD.
If you are using the CAT in clinical practice please visit the Clinical Practice area to access more information on the use of the CAT. The CAT has been translated and validated for use in more than 50 languages other than English. Only approved translations of the CAT may be used.
