This score compares the score of the test-taker to those in the NIHToolbox nationally representative normative sample within the same age band, where a score of 50indicates performance that was at the national average for the test-taking participants age. PRO scale scores have a mean of 50 and an SD of 10 (commonly known as T-Scores). This higher score indicates that a participant reports more of the concept being measured; however,whether this represents overall better or worse functioning depends on the specific measure andwhether it is a positively or negatively worded concept (e.g., general life satisfaction vs. hostility).Therefore, it is important to read each PRO measure scoring description below.
