Reliability and validity of the Turkish version of the fibromyalgia rapidscreening tool (FiRST)

摘要

[Purpose] An easy-to-use, psychometrically validated screening tool for fibromyalgia is needed. This study aims to evaluate the reliability and validity of the Turkish version of the Fibromyalgia Rapid Screening Tool by correlating it with 2013 American College of Rheumatology alternative diagnostic criteria and the Hospital Anxiety and Depression Scale. [Subjects and Methods] Subjects were 269 Physical Medicine and Rehabilitation clinic outpatients. Patients completed a questionnaire including the Fibromyalgia Rapid Screening Tool (twice), 2013 American College of Rheumatology alternative diagnostic criteria, and the Hospital Anxiety and Depression Scale. Scale reliability was examined by test-retest. The 2013 American College of Rheumatology alternative diagnostic criteria was used for comparison to determine criterion validity. The sensitivity, specificity, and positive and negative likelihood ratios were calculated according to 2013 American College of Rheumatology alternative diagnostic criteria. Logistic regression analysis was conducted to find the confounding effect of the Hospital Anxiety and Depression Scale on Fibromyalgia Rapid Screening Tool to distinguish patients with fibromyalgia syndrome. [Results] The Fibromyalgia Rapid Screening Tool was similar to the 2013 American College of Rheumatology alternative diagnostic criteria in defining patients with fibromyalgia syndrome. Fibromyalgia Rapid Screening Tool score was correlated with 2013 AmericanCollege of Rheumatology alternative diagnostic criteria subscores. Each point increase inFibromyalgia Rapid Screening Tool global score meant 10 times greater odds of experiencingfibromyalgia syndrome. [Conclusion] The Turkish version of the Fibromyalgia RapidScreening Tool is reliable for identifying patients with fibromyalgia.
