UPDATE: Some of our members got together and decided the DLQI used by dermatologists didn't give a good representation of how psoriasis affects our daily life, so we decided to make our own version and this is what we came up with:
https://psoriasisclub.com/psoriasisquali...score.html
This thread is intended to give you some information on the Dermatology Life Quality Index (DLQI) which your dermatologist may use.
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 over 33 different skin conditions in over 33 countries and is available in 85 languages. Its use has been described in over 800 publications including many multinational studies. The DLQI is the most frequently used instrument in studies of randomised controlled trials in dermatology.
Instructions for use
The Dermatology Life Quality Index questionnaire is designed for use in adults, i.e. patients over the age of 16. It is self explanatory and can be simply handed to the patient who is asked to fill it in without the need for detailed explanation. It is usually completed in one to two minutes.
Scoring
The scoring of each question is as follows:
Very much scored 3
A lot scored 2
A little scored 1
Not at all scored 0
Not relevant scored 0
Question unanswered scored 0
Question 7: "prevented work or studying" scored 3
The DLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired. The DLQI can also be expressed as a percentage of the maximum possible score of 30.
**Please Note: That the scores associated with the different answers should not be printed on the DLQI itself, as this might cause bias**
Meaning of DLQI Scores
0-1 = no effect at all on patient's life
2-5 = small effect on patient's life
6-10 = moderate effect on patient's life
11-20 = very large effect on patient's life
21-30 = extremely large effect on patient's life
Detailed analysis of the DLQI
The DLQI can be analysed under six headings as follows:
Symptoms and feelings Questions 1 and 2 Score maximum 6
Daily activities Questions 3 and 4 Score maximum 6
Leisure Questions 5 and 6 Score maximum 6
Work and School Question 7 Score maximum 3
Personal relationships Questions 8 and 9 Score maximum 6
Treatment Question 10 Score maximum 3
The scores for each of these sections can also be expressed as a percentage of either 6 or 3.
Interpretation of incorrectly completed questionnaires
There is a very high success rate of accurate completion of the DLQI. However, sometimes subjects do make mistakes.
1. If one question is left unanswered this is scored 0 and the scores are summed and expressed as usual out of a maximum of 30.
2. If two or more questions are left unanswered the questionnaire is not scored.
3. If question 7 is answered 'yes' this is scored 3. If question 7 is answered 'no' or 'not relevant' but then either 'a lot' or 'a little' is ticked this is then scored 2 or 1.
4. If two or more response options are ticked, the response option with the highest score should be recorded.
5. If there is a response between two tick boxes, the lower of the two score options should be recorded.
6. The DLQI can be analysed by calculating the score for each of its six sub-scales (see above). When using sub-scales, if the answer to one question in a sub-scale is missing, that sub-scale should not be scored.
