The Family Dermatology Life Quality Index is a questionnaire designed for adult (more than 16 years of age) family members or partners of patients with any skin disease. It is self explanatory and can be simply handed to the patient's family member/partner who is asked to fill it in without the need for detailed explanation. It is usually completed in two to three minutes.
The FDLQI is designed to be used as an additional outcome measure in conjunction with the DLQI or any other patient-completed questionnaire. It can be used by researchers carrying out evaluation research or by clinicians in order to assist the clinical consultation, evaluation and clinical decision making process. There is no need to seek specific permission for clinical use and there is no charge for the use of the FDLQI in this context. However it is a requirement that every copy of the FDLQI, in whatever language, should always reprint the copyright statement at the end of the FDLQI.
The above permission does not affect the requirement for seeking of permission and of possible payment when the FDLQI is used for research purposes.
The FDLQI is copyright world-wide and can only be reprinted with permission from the authors (except for routine clinical purposes; see above).

Link to the Translation guidelines (PDF Version)The scoring of each question is as follows:
Not at all/Not relevant | scored 0 |
A little | scored 1 |
Quite a lot | scored 2 |
Very much | scored 3 |
Not relevant | scored 0 |
Question unanswered | scored 0 |
The FDLQI total score 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 FDLQI can also be expressed as a percentage of the maximum possible score of 30.
Interpretation of incorrectly completed questionnaires
There is a very high success rate of accurate completion of the FDLQI. 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 two or more response options are ticked, the response option with the highest score should be recorded.
4. If there is a response between two tick boxes, the lower of the two score options should be recorded.
There is a small charge for the use of the FDLQI (Except where the FDLQI is used for routine clinical purposes). This charge is based upon the total number of subjects to whom the Index is administered. It is not based upon the frequency with which the questionnaires are administered to each individual.
These charges are always waived by the copyright holders for non-funded 'academic' studies and they are mainly applied to pharmaceutical companies using these Indexes in Phase II and Phase III studies. Please contact the authors concerning this. The charge per subject is as follows: UK: £5
USA and rest of world: $9.50 (Plus exchange rate at the time of invoicing)
Payment should be made after receipt of an invoice from the Cardiff University School of Medicine.
