Family Dermatology Life Quality Index

The Family Dermatology Life Quality Index (FDLQI) is a questionnaire designed for adult (more than 16 years of age) family members or partners of patients (of any age) 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.

The questionnaire is designed to be used alone or as an additional outcome measure in conjunction with any patient-completed questionnaire, such as the Dermatology Life Quality Index (DLQI).

This questionnaire can be used in a range of settings by clinicians, pharmaceutical companies, with-profit organisations, students or researchers.

Depending on who you are and what you're using the questionnaire for, you may need to apply for licence and pay a fee.

How to score it

The scoring of each question is:

  • Not at all/Not relevant = 0
  • A little = 1
  • Quite a lot = 2
  • Very much = 3
  • Not relevant = 0
  • Question unanswered = 0

The 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 questionnaire can also be expressed as a percentage of the maximum possible score of 30.

Interpreting incorrectly completed questionnaires

There is a very high success rate of accurate completion of the questionnaire. However, sometimes subjects do make mistakes. 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.

If two or more questions are left unanswered, the questionnaire is not scored. If two or more response options are ticked, the response option with the highest score should be recorded. If there is a response between two tick boxes, the lower of the two score options should be recorded.
