COPD Assessment Test (CAT) / Chronic Airways Assessment Test (CAAT)

The COPD Assessment Test (CAT) is a questionnaire for people with Chronic Obstructive Pulmonary Disease (COPD), designed to assess its impact on a person's life. Subsequently it has been used in ILD and bronchiectasis.

The Chronic Airways Assessment Test (CAAT) is a very small validated modification of the CAT to permit its application to asthma as well as COPD.

Please see below for access to the CAT and CAAT.
