Currently available tools to monitor patients with chronic prurigo over time focus on pruritus and quality of life parameters, while no instrument objectively assessing the pruriginous lesions is yet available.
The objective of this study was to develop a physician-assessed Prurigo Activity Score (PAS), a new tool to monitor the distribution and activity of chronic prurigo lesions and to evaluate its reliability and validity.
The 7-item PAS questionnaire as well as validated pruritus intensity scales (VAS, NRS) and a skin-related quality of life score (DLQI) were completed for 264 patients (172 females, age 61 years) at least twice over a period of 2 years. In addition, a 60-min test-retest reliability test was performed by four experts for a random sample of 12 patients.
The PAS showed good test-retest reliability (Cohens κ > 0.61; Cronbach-alpha > 0.76), ordinal or metric items showed high inter-rater reliability (Kendalls > 0.61) and items recording the number of lesions correlated significantly to each other (P < 0.001). The highest correlation to external constructs was achieved with DLQI. The feasibility test conducted by four raters indicated the suitability of PAS for tracking chronic prurigo in the clinical setting.
The PAS is a useful tool to objectively monitor pruriginous lesions in chronic prurigo patients over time. The sensitivity of change in the PAS score should be analysed in future studies.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 4. 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 22 January 2026.
All research outputs
#11,905,711
of 34,376,207 outputs
Outputs from Journal of the European Academy of Dermatology & Venereology
#2,654
of 5,862 outputs
Outputs of similar age
#149,697
of 373,812 outputs
Outputs of similar age from Journal of the European Academy of Dermatology & Venereology
#49
of 93 outputs
Altmetric has tracked 34,376,207 research outputs across all sources so far. This one has received more attention than most of these and is in the 64th percentile.
So far Altmetric has tracked 5,862 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.7. This one has gotten more attention than average, scoring higher than 53% 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 373,812 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 58% of its contemporaries.
We're also able to compare this research output to 93 others from the same source and published within six weeks on either side of this one. This one is in the 46th percentile – i.e., 46% of its contemporaries scored the same or lower than it.
