Score Cut Point Methods

Cut points are used to interpret a score at a single point in time (e.g., Fatigue T-score = 65). Empirically established cut points or thresholds can be derived that communicate the severity level or clinical meaningfulness of a score. Learn more>>  


Meaningful Change Methods

Meaningful change estimates are used to interpret the difference in a score between two points in time (e.g., Change of 6 points on the T-score metric between time of diagnosis and 3 months after initiating a new treatment). Defining the magnitude of change that corresponds to “important” change is necessary for applications such as comparative effectiveness research. There are many terms for these levels of change (e.g., clinically important change, minimally important difference, minimally perceptible change) and many methods for estimating them.

G-code Severity Modifier Methods

Scores from select PROMIS® and Neuro-QoLTM measures can be mapped directly to G-code severity modifiers required by the Centers for Medicare and Medicaid. Learn more>>  


Linking Measures

The PROsetta Stone® project developed mathematical links between legacy measures and PROMIS, Neuro-QoL, and NIH Toolbox® scores. This puts different measures on the same metric. Learn more>>
