Cardiff Acne Disability Index (CADI)

Background information

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.

Instructions for scoring

The scoring of each answer is as follows:
(a) 3
(b) 2
(c) 1
(d) 0
The CADI score is calculated by summing the score of each question resulting in a possible maximum of 15 and a minimum of 0. The higher the score, the more the quality of life is impaired.

We would recommend that if one item is not answered, that item should be scored zero and the score for that completion would be the sum of the scores of the other four items (not adjusted). If more than one item is not scored, the questionnaire cannot be scored and the entire score should be set to "missing".
