Smartphone photographs were evaluated by a physician-assessing erythema, induration, and scaling on a scale from 0 to 4 based on Psoriasis Area Severity Index (PASI). Self-assessment was done on a scale from 0 to 10 and converted to 0\u20134 scale (0 converted to 0; 1\u20133 to 1; 4\u20136 to 2; 7\u20138 to 3; and 9\u201310 to 4). Intraclass correlation coefficients with 95% confidence intervals (CIs) were calculated. <b><i>Results:<\/i><\/b> In total, 187 patients (63% women) with mean age of 38 years were included. Self-assessment scores were higher than physicians\u2019 assessment scores for all groups, and scaling was closest to the physicians\u2019 assessment, while erythema and induration had a greater distance between the physicians\u2019 and patients\u2019 assessment. The correlation between self-assessed and physician-assessed psoriasis severity for all patients was 0.23 (95% CI: 0.0\u20130.92); 0.34 (95% CI: 0.0\u20130.95) for chronic patients; and 0.09 (\u22120.01 to 0.82) for non-chronic patients. The agreement was better for men (0.53 [\u22120.02 to 0.98]) than for women (0.12 [\u22120.01 to 0.84]). <b><i>Conclusion:<\/i><\/b> There was weak agreement between self-assessed psoriasis severity and photographically assessed severity by the physician. Consumer-driven RWD should be interpreted with caution. <\/jats:p>","DOI":"10.1159\/000536175","type":"journal-article","created":{"date-parts":[[2024,1,10]],"date-time":"2024-01-10T22:00:27Z","timestamp":1704924027000},"page":"362-368","source":"Crossref","is-referenced-by-count":1,"title":["The Agreement between Consumer-Driven Self-Assessment of Psoriasis Severity and Physician-Assessed Severity Based on Patient-Taken Photographs Is Weak: A Cross-Sectional Study"],"prefix":"10.1159","volume":"240","author":[{"given":"Zarqa","family":"Ali","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Al-Mousawi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ben\u00f3n\u00fd \u00de\u00f3r","family":"Bj\u00f6rnsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Egeberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Riemer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon Francis","family":"Thomsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2024,1,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms20061475"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.4103\/picr.picr_62_21"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159\/000516178"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdin.2023.02.004"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.12106"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s11136-013-0384-y"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcm.2016.02.012"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.det.2014.09.005"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2004.04.012"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1111\/1523-1747.ep12329912"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159\/000530045"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.2196\/34204"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1002\/hsr2.1219"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1111\/srt.13226"}],"container-title":["Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/drm\/article-pdf\/240\/3\/362\/4240478\/000536175.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/drm\/article-pdf\/240\/3\/362\/4240478\/000536175.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:04:59Z","timestamp":1745424299000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000536175"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024]]},"references-count":14,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2024,6,11]]},"published-print":{"date-parts":[[2024,6,12]]}},"URL":"https:\/\/doi.org\/10.1159\/000536175","archive":["Portico"],"relation":{},"ISSN":["1018-8665","1421-9832"],"issn-type":[{"value":"1018-8665","type":"print"},{"value":"1421-9832","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024]]}}}
