The Cardiff Acne Disability Index (CADI) (Motley and Finlay, 1992) is a short 5 item questionnaire derived from the longer Acne Disability Index (Motley and Finlay, 1989).
The Cardiff Acne Disability Index is designed for use in teenagers and young adults with acne. It is self explanatory and can be simply handed to the patient who is asked to complete it without the need for detailed explanation. It is usually completed in one minute.
