Evaluation of the Dermatology Life Quality Index scoring modification, the DLQI‐R score, in two independent populations

Abstract

The 10‐item Dermatology Life Quality Index (DLQI) is an easily administered health‐related quality of life instrument often utilized in dermatologic studies, including clinical trials for psoriasis. However, there have been questions regarding how best to score 'not relevant' responses (NRRs) on the DLQI since these can be common and could lead to underestimation of the impact on quality of life. Recently, Rencz and colleagues proposed a scoring modification for the DLQI, the DLQI‐R score, in which the traditional DLQI score is multiplied by a conversion factor that increases with the number of NRRs. In their reanalysis of 242 patients involved in two cross‐sectional surveys conducted in Hungary, they found that the DLQI‐R displayed moderate correlation with Psoriasis Area Severity Index (PASI) scores and EQ‐5D‐3L index values, with higher correlation coefficients than the traditional DLQI score.
