Hello and Welcome to the COPD Assessment Test website.

Chronic obstructive pulmonary disease (COPD) is a disease of the lungs, which makes it very difficult to breathe. The symptoms experienced by people with COPD, such as ongoing cough, shortness of breath, wheezing, and chest tightness, can restrict them from performing simple activities, like washing or getting dressed.

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 very simple to administer, and aims to help clinicians manage a patient's COPD better. You may, for personal use and for research purposes, read, view, print download and copy the material on this website in accordance with the license to copy for personal use conditions stipulated in the legal notices.

Whether you're a healthcare professional, a patient, or a member of the public, you can use this website to find out more about the CAT.

CAT has been translated and validated in many languages. To see more information on CAT in different languages and to take the test please click on the “Take the Test” button.
