| Abstract |
The aim of this study was to assess the psychometric properties of the five-level (EQ-5D-5L) in comparison with the standard three-level (EQ-5D-3L) classification systems of the EQ-5D in a sample of psoriatic patients. Psoriatic subjects (n = 396) recruited from 16 private practicing centers from various areas of Greece self-completed the two EQ-5D versions and the Dermatology Life Quality Index, while information was also collected on socio-demographics, clinical characteristics and comorbidities. The EQ-5D-5L and EQ-5D-3L were evaluated in terms of agreement, feasibility, ceiling effects, redistribution properties, inconsistency, informativity, and convergent and known-groups validity. Missing values were negligible in both versions. The agreement between the EQ-5D-5L and the EQ-5D-3L was very high (ICC = 0.94), while the largest differences were identified for subjects with moderate health status. Ceiling effects decreased in the EQ-5D-5L system by 14.08% (p < 0.05), with "anxiety/depression" showing the highest relative reduction (-10.31%; p < 0.05). Overall inconsistency was rather low (1.7%) and respondents preferred to report milder problems in the EQ-5D-5L. Absolute informativity improved by 56.42% in the EQ-5D-5L, while relative informativity declined by 9.24%, with only "anxiety/depression" demonstrating a small increase (6.77%). Both instruments demonstrated good convergent and known-groups validity, with evidence of a slightly better convergent performance and discriminatory efficiency of the EQ-5D-5L. In conclusion, both instruments demonstrated consistency, valid redistribution and good construct validity. The EQ-5D-5L system may be preferable to the EQ-5D-3L in psoriatic patients, as it demonstrated a marginally better performance in terms of reduced ceiling effects, increased informativity, and improved convergent and known-groups validity efficiency, particularly in the domain of "anxiety/depression". |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 27 March 2024.
All research outputs
#5,210,996
of 25,641,627 outputs
Outputs from Archives of Dermatological Research
#201
of 1,455 outputs
Outputs of similar age
#82,993
of 325,946 outputs
Outputs of similar age from Archives of Dermatological Research
#3
of 10 outputs
Altmetric has tracked 25,641,627 research outputs across all sources so far. Compared to these this one has done well and is in the 79th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,455 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.0. This one has done well, scoring higher than 86% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 325,946 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 74% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
