We aimed to determine the sensitivity to change of the Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI\u2010s), the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), the Radiographic Ankylosing Spondylitis Spine Score (RASSS), and the PsA Spondylitis Radiology Index (PASRI) in axial PsA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Radiographs of 105 patients with axial PsA were retrieved for 2 time points at least 2 years apart and subsequently anonymized. All radiographs were scored by 3 rheumatologists blinded to name and order of examination using an electronic application that allowed recording of disease manifestations specific to axial PsA and automatically calculated the BASRI\u2010s, mSASSS, RASSS, and PASRI scores. An independent expert determined whether there was true radiographic progression from an overall impression after viewing the radiographs with knowledge of chronologic order. The sensitivity, specificity, and odds ratios for every 1\u2010unit increase in the scores were determined to identify true change.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the patients studied, 25 (24%) showed progression, as determined by the independent expert. The respective sensitivity and specificity values for an increase in score to detect true change were as follows: 0.48 and 0.78 (BASRI\u2010s), 0.52 and 0.84 (mSASSS), 0.44 and 0.84 (RASSS), and 0.52 and 0.74 (PASRI). Logistic regression analyses showed that an increase of 1 point in the respective scores was associated with the following odds ratios for identifying true progression: BASRI\u2010s 3.0, mSASSS 5.27, RASSS 3.70, and PASRI 3.06.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Available scoring systems for quantifying radiographic axial PsA have moderate sensitivity but high specificity for detecting true change.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acr.23189","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T17:58:09Z","timestamp":1484330289000},"page":"1700-1705","source":"Crossref","is-referenced-by-count":17,"title":["Sensitivity and Specificity of Radiographic Scoring Instruments for Detecting Change in Axial Psoriatic Arthritis"],"prefix":"10.1002","volume":"69","author":[{"given":"Ali","family":"Ibrahim","sequence":"first","affiliation":[{"name":"Centre for Prognosis Studies in the Rheumatic Diseases\u2013Toronto Western Hospital, Krembil Research Institute University Health Network Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dafna D.","family":"Gladman","sequence":"additional","affiliation":[{"name":"Centre for Prognosis Studies in the Rheumatic Diseases\u2013Toronto Western Hospital, Krembil Research Institute University Health Network, and University of Toronto Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arane","family":"Thavaneswaran","sequence":"additional","affiliation":[{"name":"Centre for Prognosis Studies in the Rheumatic Diseases\u2013Toronto Western Hospital, Krembil Research Institute University Health Network Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lihi","family":"Eder","sequence":"additional","affiliation":[{"name":"Centre for Prognosis Studies in the Rheumatic Diseases\u2013Toronto Western Hospital, Krembil Research Institute University Health Network, and University of Toronto Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip","family":"Helliwell","sequence":"additional","affiliation":[{"name":"Leeds Institute of Rheumatic and Musculoskeletal Medicine University of Leeds Leeds UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard J.","family":"Cook","sequence":"additional","affiliation":[{"name":"University of Waterloo Waterloo Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vinod","family":"Chandran","sequence":"additional","affiliation":[{"name":"Centre for Prognosis Studies in the Rheumatic Diseases\u2013Toronto Western Hospital, Krembil Research Institute University Health Network, and University of Toronto Toronto Ontario Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,9,21]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.21972"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11926-007-0074-2"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780140302"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.57.3.135"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.61.7.650"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.51.1.73"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.semarthrit.2004.05.001"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.332.7542.639"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2006.066415"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.20446"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/1529-0131(199812)41:12<2263::AID-ART23>3.0.CO;2-I"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1136\/ard.2004.020503"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.24425"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.3899\/jrheum.080491"},{"key":"e_1_2_7_16_1","first-page":"977","article-title":"The radiological assessment of axial involvement in psoriatic arthritis: a validation study of the BASRI total and the modified SASSS scoring methods","volume":"27","author":"Lubrano E","year":"2009","journal-title":"Clin Exp Rheumatol"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.22308"},{"key":"e_1_2_7_18_1","first-page":"198","article-title":"The OMERACT filter for Outcome Measures in Rheumatology","volume":"25","author":"Boers M","year":"1998","journal-title":"J Rheumatol"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780270401"}],"container-title":["Arthritis Care &amp;
