PRP skin involvement can cause functional impairments and emotional distress leading to decreased quality of life. There is no clinical tool explicitly developed for PRP. The Individual Pityriasis Rubra Pilaris Area and Severity Index (iPRPASI) was developed as a patient-reported outcomes measure to capture the more nuanced features of PRP, such as the high prevalence of palmoplantar keratoderma. An assessment of the validity, reliability, and responsiveness of the iPRPASI is conducted in this study. 000041875 540__ $$fCC BY 000041875 542__ $$fIn copyright - joint owners 000041875 650__ $$aQuality of Life$$025032 000041875 650__ $$aPityriasis Rubra Pilaris$$024206 000041875 650__ $$aPatient Acuity$$040012 000041875 650__ $$aPatient Reported Outcome Measures$$011677 000041875 650__ $$aDermatology$$017631 000041875 650__ $$aRare Diseases$$034662 000041875 650__ $$aSkin Diseases, Papulosquamous$$029973 000041875 650__ $$aSeverity of Illness Index$$025910 000041875 650__ $$aKeratoderma, Palmoplantar$$021163 000041875 6531_ $$aPRP 000041875 6531_ $$aclinical tools 000041875 691__ $$aSchool of Medicine$$041369 000041875 692__ $$aDepartment of Dermatology$$041406 000041875 7001_ $$aShao, Connie$$uOregon Health and Science University$$041354 000041875 7001_ $$aVelasco, Rose$$uOregon Health and Science University$$041354 000041875 7001_ $$aGreiling, T.M.$$uOregon Health and Science University$$041354 000041875 711__ $$aResearch Week$$uOregon Health and Science University$$d2023 000041875 8564_ $$9a9734f03-73ff-4a17-bcf8-0f13808d45fc$$s267864$$uhttps://digitalcollections.ohsu.edu/record/41875/files/ResearchWeek.2023.Shao.Connie.pdf 000041875 980__ $$aResearch Week 000041875 981__ $$aPublished$$b2023-09-08
