Comparison of information content between 6 instruments. The most precise instruments have curves that are below and broader than the less-reliable instruments. Reliability at the “floor” is represented by the left side of the curves and reliability at the “ceiling” is represented by the right side of the curves. The 10-item PROMIS CAT covers 6.4 population SD and has much greater precision in normal populations (less ceiling effect). Reprinted from Fries, et al. J Rheumatol 2009;36:2061–6.
