Measurement properties of the EQ-5D-5L compared to the EQ-5D-3L in psoriasis patients

Abstract

The EQ-5D-5L seems to improve measurement properties by reducing ceiling effects, strengthening correlations with PASI and improving informativity. Follow-up studies are needed to test responsiveness and reliability in psoriasis.

Validity of the EQ ‐5D in patients with pemphigus vulgaris and pemphigus foliaceus

“…Analysis of the relationship between continuous variables was accomplished by calculating Spearman's correlation coefficients (very weak correlation: r s < 0·2, weak 0·20–0·4, moderate 0·4–0·6 and strong 0·6–1). The EQ‐5D‐5L and EQ VAS results were compared with responses from a group of Hungarian patients with psoriasis obtained in a previous study by our research group ( n = 238, mean age 47·4 ± 15·2 years, proportion with moderate‐to‐severe psoriasis 81%) . For all the statistical tests a two‐sided P ‐value < 0·05 was considered statistically significant.…”

A detailed analysis of ‘not relevant’ responses on the DLQI in psoriasis: potential biases in treatment decisions

“…Data from two cross‐sectional questionnaire surveys among psoriasis patients aged 18 or above were combined. Detailed methodology of the studies has been published elsewhere . Both surveys have been performed in a paper‐based fashion at academic dermatology clinics in Hungary.…”

“…A description of the DLQI and its scoring is provided in the Introduction. General health status and HRQoL were measured by the Hungarian version of the EQ‐5D‐3L (hereinafter referred as EQ‐5D) questionnaire, which showed a good validity and responsiveness in psoriasis . It consists of two measures, the EQ‐5D descriptive system and the EQ visual analogue scale (EQ VAS).…”

“…Detailed methodology of the studies has been published elsewhere. [39][40][41][42][43] Both surveys have been performed in a paper-based fashion at academic dermatology clinics in Hungary. The first study was carried out between September 2012 and May 2013 at two clinics: Semmelweis University, Department of Dermatology, Venereology and Dermatooncology (hereinafter referred as clinic #1) and University of Debrecen, Department of Dermatology (hereinafter referred as clinic #2).…”

“…General health status and HRQoL were measured by the Hungarian version of the EQ-5D-3L (hereinafter referred as EQ-5D) questionnaire, which showed a good validity and responsiveness in psoriasis. [43][44][45][46] It consists of two measures, the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system is based on the following five dimensions of HRQoL: mobility, self-care, usual activities, pain/ discomfort and anxiety/depression.…”
