The Cardiff Acne Disability Index (CADI) is a simple questionnaire for assessing the disability caused by acne. It consists of 5 questions dealing with interference in life functions or psychosocial adjustment caused by acne, which are graded from 3 (greatly) to 0 (none). It can be used over time to evaluate disease activity and response to therapeutic interventions.
The instrument consists of 5 questions asking about the impact of acne over the past month.
