Improving Health Measurement in Rheumatology

Session Type: ARHP Concurrent Sessions
Tuesday, November 8, 2011: 4:30 PM-6:00 PM
W474b (McCormick Place West)
Clinical and Research  SessionSelect

Session Overview:
The current generation of clinical measures (such as the DAS28) and patient-reported outcomes (such as the HAQ) in rheumatology have been developed using classical test theory methods. Although these measures have served researchers and clinicians well, they are not without their limitations. New analysis and measurement techniques, such as item response theory methods and computerized adaptive testing, have become available and can overcome many of the limitations of current measures and are likely to result in shorter, yet more robust and precise, new measures. However, the vast majority of researchers in rheumatology are not very familiar and skilled in the basic principles of these measurement techniques. The advantages of modern measurement techniques by providing practical and state-of-the-art examples of modern measurement of both patient-reported and clinical measures in rheumatology will be demonstrated.

Upon completion of this session, participants should be able to:

  • discuss the differences between classical and modern test theory methods for health measurement            
  • contrast advantages of modern versus classical measurement methods for clinical and patient-reported measures in rheumatology
  • describe recent developments and current projects relevant to rheumatology
