It complements existing approaches to assessing COPD, such as FEV 1 measurement. It was initially designed, using a rigorous scientific development process, to provide a simple and reliable measure of health status in COPD to aid assessment of patients and promote communication between patients and clinicians.  \nValidation studies conducted during the development of CAT and in the years since it was launched in 2009 have shown that it has properties very similar to much more complex health status questionnaires such as the St George’s Respiratory Questionnaire (SGRQ) 1. A recent systematic review2 confirmed that the CAT provides reliable measurement of health status and is responsive to change with treatment and exacerbations. Since 2013 it has been incorporated as the preferred measure of symptomatic impact of COPD into clinical assessment schemes and is also included in the COPD Foundation guide 17.  \nAlthough it was developed in English , nearly one hundred validated translations have been made and local validation studies have been conducted in countries that include China, Arabic-speaking countries, Brazil, Greece, Japan, South Korea , Turkey and Thailand. All have shown that the CAT is reliable in those setting and that both patients and researchers find it easy to use.  \nSince the launch of CAT, guidance has been provided for health care professionals on how to use and interpret CAT scores in the form of a user manual available through the website ([www.CATestonline.org](www.CATestonline.org)) . As it is increasingly used in research this update to the user manual has been expanded to include information and advice to researchers, based upon our current knowledge of the CAT and its measurement properties.  \nThe information in this guide is accompanied by some frequently asked questions in order to make it accessible and applicable to both practice and research.  \nWe look forward to hearing and reading about your experiences using the CAT in the near future!  \nProfessor Mike Polkey Independent Chair  \nProfessor Claus Vogelmeier  \nGOLD Science Committee Chair  \nProfessor Mark Dransfield  \nCOPD Foundation Consortium Working Group Chair  \nOn behalf of the CAT Governance Board , May 2022  \nThe COPD Assessment Test (CAT)– the basics  \nWhat is the CAT?  \nThe CAT is a validated, short (8-item) and simple patient completed questionnaire , with good discriminant properties, developed for use in routine clinical practice to measure the health status of patients with COPD 1. Despite the small number of component items, it covers a broad range of effects of COPD on patients’ health. Studies have shown that it is responsive to change and to treatment.2,3,4  \nWhy has the CAT been developed?  \nCOPD represents a major burden on patients and healthcare systems. Despite the fact that it is projected to become the third leading cause of death by 20305 , communicating the impact of COPD can be difficult and this can contribute to under-management of COPD in a significant proportion of people who may suffer increased disability and reduced quality of life as a result.  \nThe care of COPD patients can only be optimised if there is a reliable , standardised measure of the overall effect of disease on each patient’s health. Unfortunately, commonly used lung function measurements such as FEV1 percent predicted do not reflect the full impact of COPD.  \nCAT was developed to address the need for a simple-to-use tool which can measure the effect of COPD on the patient’s health and enhance understanding between patients and physicians of the disease’s impact , in order to manage patients optimally and reduce the burden of disease as much as possible.  \nDevelopment ","cbCaieLwOjlCdxtz","https://ap.wps.com/l/cbCaieLwOjlCdxtz","pdf",247332,16,"English","# The CAT– the basics\n## What is the CAT?\n## Why has the CAT been developed?\n# Development and Governance of the COPD Assessment Test (CAT)\n## How was the CAT developed?\n## Who developed the CAT?\n## How is the CAT governed?","[{\"question\":\"What is the CAT and what does it measure?\",\"answer\":\"The CAT is a validated, short (8-item) patient-completed questionnaire that measures the health status impact of COPD across a broad range of effects.
