Background

The Dermatology Quality of Life Index (DLQI) is the most commonly used quality of life questionnaire in dermatology.

Objectives

The aim of this study was to compare the DLQI to measures of wellbeing and general quality of life in patients with chronic inflammatory skin diseases.

Materials & Methods

A cross-sectional study among patients with psoriasis and atopic dermatitis was conducted at a hospital in Munich, Germany (12/2017-04/2019). Participants filled in validated scales measuring happiness, quality of life, and DLQI.

Results

In 102 patients with chronic inflammatory skin diseases, the DLQI was associated only with physical quality of life and negative emotions, and not psychological quality of life or positive affect. The DLQI alone accounted for 26% of variance in general quality of life. Combining DLQI and happiness accounted for a total of 73% of variance, with both variables contributing to the model.

Conclusion

The DLQI alone only partially reflected well-being. Assessing happiness in addition to the widely used DLQI can contribute to a more comprehensive evaluation of well-being.
