The Cardiff Acne Disability Index

This short questionnaire of five questions asks teenagers and young adults to rate the impact that their acne is having on them on a scale of 0–3, the total maximum score being 15. This is a quick and practical tool that can be given to a patient to complete in clinic and then used as a basis for discussion about the impact of the disease as well as being used as a tool to monitor the effectiveness of treatment (Motley & Finlay, 1992).

This tool is available at www.dermatology. org.uk and can be used free of charge in clinical situations.
