How to score it
The Infants' Dermatitis Quality of Life Index 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 severity of eczema is scored separately and can be correlated with the Infants' Dermatitis Quality of Life Index.
This is scored separately from the Life Quality Index.
- Extremely severe = 4
- Severe = 3
- Average = 2
- Fairly good = 1
- None = 0
