It  has eight items (questions), which encompass physical, psychological and social aspects of daily life.  Each item has three response levels.The patients complete this questionnaire themselves, which has a recall period of a week.  


The CATQoL instrument was developed using “bottom-up” methods, and patient data was used at every stage in the instrument design.  The instrument has been shown to have good content and face validity.  The psychometric properties of the CAT-QoL instrument have been assessed following a multi-centre United Kingdom (UK) validation study.  A Rasch scoring conversion chart is available.
