Although there are scoring systems available for disease severity, there is as yet no scale to evaluate the impact of this condition upon the patients\u2019 quality of life.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Objectives\u2002<\/jats:bold>\n                    This study aims to develop and validate a quality of life scale specifically for nail psoriasis.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods\u2002<\/jats:bold>\n                    A questionnaire was developed during a study conducted in France between 2004 and 2005. With the cooperation of l\u2019Association Pour la Lutte Contre le Psoriasis, the questionnaire was sent to a random sample of 4000 of its 17\u00a0000 members.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results\u2002<\/jats:bold>\n                    The response rate was 33%. Of the 1309 questionnaires returned, 795 showed the presence of nail psoriasis and these were eligible. The scale score is obtained by adding together the responses to the 10 questionnaire items and the result is expressed as a percentage. The value of the score obtained is proportional to the functional difficulty experienced. The determination of Cronbach's \u03b1 coefficient and a Principal Component Factor Analysis show, respectively, very good internal consistency and the unidimensional nature of the scale. Test\u2013retest results on 15 patients showed good reproducibility. Results were validated with reference to the Dermatology Life Quality Index.\n                  <\/jats:p>\n                  <jats:p>In this study, the NPQ10 score is significantly influenced by gender (women have a higher score) and by the duration of psoriasis (recent onset implies greater functional difficulty). Finally, the score is much higher when the nail psoriasis affects both the hands and the feet.<\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusion\u2002<\/jats:bold>\n                    This study confirms a change in the quality of life of patients who have nail psoriasis. The NPQ10 scale, specific to this condition, is simple to use and has the attributes needed in a quality of life scale. The scale must now be tested in longitudinal studies (such as clinical trials) to confirm its ability to measure a change in status.\n                  <\/jats:p>","DOI":"10.1111\/j.1468-3083.2009.03344.x","type":"journal-article","created":{"date-parts":[[2009,7,3]],"date-time":"2009-07-03T03:19:36Z","timestamp":1246591176000},"page":"22-27","source":"Crossref","is-referenced-by-count":76,"title":["Development and validation of nail psoriasis quality of life scale (NPQ10)"],"prefix":"10.1111","volume":"24","author":[{"given":"JP","family":"Ortonne","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R","family":"Baran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Corvest","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Schmitt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JJ","family":"Voisard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Taieb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,12,7]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2133.1963.tb13535.x"},{"key":"e_1_2_7_3_2","first-page":"201","volume-title":"Psoriasis","author":"Tosti A","year":"1994"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000246274"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10227-002-0143-0"},{"key":"e_1_2_7_6_2","first-page":"482","article-title":"Clinical observations on nail changes in psoriasis","volume":"17","author":"Tham SN","year":"1988","journal-title":"Ann Acad Med Singapore"},{"key":"e_1_2_7_7_2","first-page":"113","article-title":"The nails in psoriatic arthritis.","volume":"186","author":"Lavaroni G","year":"1994","journal-title":"Acta Derm Venereol Suppl (Stockh)"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/9780470694947"},{"key":"e_1_2_7_9_2","first-page":"56","volume-title":"Samman's Nails in Disease","author":"Samman PD","year":"1995"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)67566-6"},{"key":"e_1_2_7_11_2","first-page":"265","article-title":"La question du mois","volume":"120","author":"Baran R.","year":"1993","journal-title":"Ann Dermatol Venereol"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2230.2000.00663.x"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.3109\/09546639909056030"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02310555"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2230.1994.tb01167.x"},{"key":"e_1_2_7_16_2","unstructured":"Medical Outcomes Trust Scientific Advisory Committee.Instrument review criteria.Med Outcomes Trust Bull1995; September I\u2013IV."},{"key":"e_1_2_7_17_2","first-page":"4","volume-title":"Textbook of Psoriasis","author":"Zachariae H.","year":"1986"}],"container-title":["Journal of the European Academy of Dermatology and Venereology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1468-3083.2009.03344.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1468-3083.2009.03344.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T08:50:34Z","timestamp":1698915034000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1468-3083.2009.03344.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,12,7]]},"references-count":16,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2010,1]]}},"alternative-id":["10.1111\/j.1468-3083.2009.03344.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1468-3083.2009.03344.x","archive":["Portico"],"relation":{"has-review":[{"id-type":"doi","id":"10.3410\/f.3559958.3266056","asserted-by":"object"}]},"ISSN":["0926-9959","1468-3083"],"issn-type":[{"value":"0926-9959","type":"print"},{"value":"1468-3083","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,12,7]]}}}
