There are eight items in the CAT.
Patients read the two statements for each item, which describe the best and worst scenario, and decide where on the scale (0-5) they fit. This system was chosen because it is reliable and simple to use. Scores for each of the 8 items are summed to give single, final score (minimum 0, maximum 40) – this is a measure of the overall impact of a patient’s condition on their life1,2.
Scores for the individual items within the questionnaire will provide insight into the relative influence that the different components of COPD have on its overall impact on a patient’s life – thus, they will highlight problematic areas, which can be explored further during consultation and ultimately addressed through intervention1,2.
