Finley, A.Y. Abstract on the Dermatology Life Quality Index (DLQI)
Statement #1 – The Dermatology Life Quality Index (DLQI) is a simple practical questionnaire technique for routine clinical use.
Comment: Some might say that the DLQI is “too simple ” and that the challenges of treating PRP should not be considered “routine clinical use”.
Statement #2 – One hundred and twenty patients with different skin diseases were asked about the impact of their disease and its treatment on their lives; a questionnaire, the DLQI, was developed based on their answers.
Comment : Considering the fact that there are over 3,000 skin disorders and nearly 600 “rare” skin disorders, a cohort of 120 seems woefully inadequate for a DLQI appropriate for pityriasis rubra pilaris.
Statement #3 – The DLQI was then completed by 200 consecutive new”patients attending a dermatology clinic. This study confirmed that a topic eczema, psoriasis and generalized pruritus have a greater impact on quality of life than acne, basal cell carcinomas and viral warts.
Comment : A case could be made that patients diagnosed with PRP would have a greater impact on quality of life than eczema, psoriasis, generalized pruritus , acne, basal cell carcinomas and viral warts.
Statement #4 – The DLQI was also completed by 100 healthy volunteers; their mean score was very low (1.6%, s.d. 3.5) compared with the mean score for the dermatology patients (24.2%, s.d. 20.9).
Comment : A case could be made that patients diagnosed with PRP would have a greater impact on quality of life than eczema, psoriasis, generalized pruritus , acne, basal cell carcinomas and viral warts.
Statement #5 – The reliability of the DLQI was examined in 53 patients using a 1 week test”retest method and reliability was found to be high (γs=0.99).
Comment : A case could be made that patients diagnosed with PRP would have a greater impact on quality of life than eczema, psoriasis, generalized pruritus , acne, basal cell carcinomas and viral warts.

Abstract
A simple practical questionnaire technique for routine clinical use, the Dermatology Life Quality Index (DLQI) is described. One hundred and twenty patients with different skin diseases were asked about the impact of their disease and its treatment on their lives; a questionnaire, the DLQI, was developed based on their answers. The DLQI was then completed by 200 consecutive new patients attending a dermatology clinic. This study confirmed that atopic eczema, psoriasis and generalized pruritus have a greater impact on quality of life than acne, basal cell carcinomas and viral warts. The DLQI was also completed by 100 healthy volunteers; their mean score was very low (1.6%, s.d. 3.5) compared with the mean score for the dermatology patients (24.2%, s.d. 20.9). The reliability of the DLQI was examined in 53 patients using a 1 week test-retest method and reliability was found to be high (gamma s = 0.99).
The aim of this questionnaire is to measure how much your skin problem has affected your life OVER THE LAST WEEK. Please tick ( ̧) one box for each question.
The aim of this questionnaire is to measure how much your skin problem has affected your life OVER THE LAST WEEK. Please tick ( ̧) one box for each question.
(1) Over the last week, how itchy, sore, painful or stinging has your skin been?
(2) Over the last week, how embarrassed or self conscious have you been because of your skin?
(3) Over the last week, how much has your skin interfered with you going shopping or looking after your home or garden?
(4) Over the last week, how much has your skin influenced the clothes you wear?
(5) Over the last week, how much has your skin affected any social or leisure activities? (
6) Over the last week, how much has your skin made it difficult for you to do any sport?
(7) Over the last week, has your skin prevented you from working or studying? If “No”, over the last week how much has your skin been a problem at work or studying?
(8) Over the last week, how much has your skin created problems with your partner or any of your close friends or relatives?
(9) Over the last week, how much has your skin caused any sexual difficulties?
(10) Over the last week, how much of a problem has the treatment for your skin been, for example by making your home messy, or by taking up time?
