Dual site, university-based outpatient clinics.<\/jats:p>\n                  <jats:p>Subjects. Women aged 20 to 67 years diagnosed with fibromyalgia.<\/jats:p>\n                  <jats:p>Methods. Participants completed the Revised Fibromyalgia Impact Questionnaire (FIQR) and 10 PROMIS static SF instruments. Internal consistency was calculated using Cronbach alpha. Convergent validity was examined against the FIQR using Pearson correlation and multiple regression analysis.<\/jats:p>\n                  <jats:p>Results. PROMIS static SF instruments had fair to high internal consistency (Cronbach \u03b1\u2009=\u20090.58 to 0.94, P\u2009&amp;lt;\u20090.05). PROMIS \u2018physical function\u2019 domain score was highly correlated with FIQR \u2018function\u2019 score (r\u2009=\u2009\u22120.73). The PROMIS \u2018total\u2019 score was highly correlated with the FIQR total score (r\u2009=\u2009\u22120.72). Correlations with FIQR total score of each of the three PROMIS domain scores were r\u2009=\u2009\u22120.65 for \u2018physical function,\u2019 r\u2009=\u2009\u22120.63 for \u2018global,\u2019 and r\u2009=\u2009\u22120.57 for \u2018symptom\u2019 domain. PROMIS \u2018physical function,\u2019 \u2018global,\u2019 and \u2018symptom\u2019 scores explained 58% of the FIQR total score variance.<\/jats:p>\n                  <jats:p>Conclusions. Select PROMIS static SF instruments demonstrate convergent validity with the FIQR, a legacy measure of fibromyalgia disease severity. These results highlight the potential utility of select PROMIS static SFs for assessment and tracking of patient-reported outcomes in fibromyalgia.<\/jats:p>","DOI":"10.1093\/pm\/pnw187","type":"journal-article","created":{"date-parts":[[2016,8,25]],"date-time":"2016-08-25T20:39:22Z","timestamp":1472157562000},"page":"1485-1495","source":"Crossref","is-referenced-by-count":18,"title":["Reliability
