Description of the Studies in General
Categories: Research Methods & Study Design
A structured overview of the characteristics of all studies included in a measurement property review. Completed before developing measurement property summary tables, this description provides the interpretive context needed to understand and compare the evidence across studies. It captures key features of the study design, patient population, setting, instrument versions, follow-up periods, and comparator measures used within the body of evidence. This contextual information helps working groups determine whether study findings are applicable and sufficiently aligned with the intended OMERACT target population and context of use.

In a review evaluating the measurement properties of a PROMIS Fatigue instrument in rheumatoid arthritis, the working group documents that included studies consisted of longitudinal cohort studies and randomized controlled trials conducted in North America and Europe, primarily involving adults with moderate-to-severe disease activity. The summary notes sample sizes, follow-up intervals, use of PROMIS CAT versus short forms, and comparator instruments such as the FACIT-Fatigue scale. This information helps determine whether the evidence is relevant and comparable for OMERACT instrument evaluation.
