Adaptive tests choose each question based on your previous answer, reaching research-grade precision in about 4–7 items instead of a fixed long form. They score on the PROMIS T-metric: US adult average 50, higher is better for function, lower is better for pain and distress.
The item-selection engine and IRT parameters for PROMIS CATs are licensed by HealthMeasures (Northwestern University) rather than published, so this page runs against a secure engine instead of scoring in the browser. Until one is connected, it demonstrates the flow with clearly labeled placeholder items and produces no score. Three routes to live, in order of institutional simplicity:
Privacy stance is unchanged: in live mode, only anonymous item responses transit the relay — no name, no identifiers, nothing stored by this page. Results print exactly like the main portal summary.
