The Infant's Dermatitis Quality of Life Index questionnaire is designed for use in infants with atopic dermatitis below the age of 4 years. It is self-explanatory and should be completed by the child's parent (s) or regular carer. It can usually be completed within 2 or 3 minutes.

The scoring of each question is as follows:
