Quality of Life

Dermatology Life Quality Index (DLQI)

The Dermatology Life Quality Index or DLQI, developed in 1994, was the first dermatology-specific Quality of Life instrument. It is a simple 10-question validated questionnaire which has been used in 33 different skin conditions in 32 countries and is available in 55 languages. Its use has been described in over 500 publications including 30 multinational studies. At present the DLQI is the most frequently used instrument in studies of randomised controlled trials in dermatology.
