These patients were randomly split into a training set (n\u00a0=\u00a0231) and a testing set (n\u00a0=\u00a056). Correlation analyses were performed to assess the relationship between DLQI (total score and item score) and EQ-5D utility index score. Twelve predictive models were developed using three statistical model approaches (ordinary least squares model, Tobit model and generalized linear model), incorporating various combinations of DLQI scores and patient characteristics (age, sex, education and comorbidities). Models were evaluated using root mean square error and mean absolute error (MAE).\n            <jats:bold>Results:<\/jats:bold>\n            A strong and significant correlation was found between DLQI total score and EQ-5D utility index score (r\u00a0=\u00a0-0.645, p\u00a0&lt;\u00a00.001). The best-performing model, (ordinary least squares model using DLQI total score, had the lowest root mean square error (0.122) and MAE (0.076). Validation of this model in the testing set yielded a predicted utility score with an MAE of 0.072, and an MAE-to-utility ratio of 0.084, below the validation threshold of 0.1.\n            <jats:bold>Conclusion:<\/jats:bold>\n            DLQI scores can reliably predict health utility values, offering a useful tool for clinical decision-making and health economic evaluations. The model shows strong predictive accuracy and has potential applications in the management of msPsO in China.\n          <\/jats:p>","DOI":"10.57264\/cer-2025-0039","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T13:48:08Z","timestamp":1752846488000},"source":"Crossref","is-referenced-by-count":2,"title":["Mapping Dermatology Life Quality Index with EQ-5D health utility index score in Chinese patients with moderate to severe psoriasis"],"prefix":"10.57264","volume":"14","author":[{"given":"Lu","family":"Jian","sequence":"first","affiliation":[{"name":"Xiangya Hospital of Central South University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingzhi","family":"Wang","sequence":"additional","affiliation":[{"name":"Bristol-Myers Squibb, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kun","family":"Hu","sequence":"additional","affiliation":[{"name":"Xiangya Hospital of Central South University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongfang","family":"Duan","sequence":"additional","affiliation":[{"name":"Xiangya Hospital of Central South University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xiangya Hospital of Central South University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Li","sequence":"additional","affiliation":[{"name":"International Research Center for Medical Administration Peking University, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pei","family":"Wang","sequence":"additional","affiliation":[{"name":"Fudan University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Tan","sequence":"additional","affiliation":[{"name":"Changsha Normin Health Technology Ltd, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9517-4745","authenticated-orcid":false,"given":"Wendong","family":"Chen","sequence":"additional","affiliation":[{"name":"Changsha Normin Health Technology Ltd, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tingyin","family":"Chen","sequence":"additional","affiliation":[{"name":"Xiangya Hospital of Central South University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Li","sequence":"additional","affiliation":[{"name":"Haidian District Meteral &amp; health care hosptial, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yehong","family":"Kuang","sequence":"additional","affiliation":[{"name":"Xiangya Hospital of Central South University, Changsha, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"36897","reference":[{"key":"e_1_3_9_3_2","doi-asserted-by":"crossref","first-page":"170","DOI":"10.7861\/clinmed.2021-0257","article-title":"Psoriasis: a brief overview","volume":"21","author":"Raharja A","year":"2021","unstructured":"Raharja A, Mahil SK, Barker JN.
