- PROMIS = Patient Reported Outcomes Measurement Information System (reported as T-scores); SF-36 = Medical Outcomes Short Form-36, MCS = Mental Component Summary, PCS = Physical Component Summary, BP = Bodily Pain; WOMAC = Western Ontario and McMaster Universities Arthritic Index; PSS = Perceived Stress Scale; BDI-II = Beck Depression Index II
- aHigher scores indicate better health-related outcomes (for other measures, higher scores indicates worse health-related outcomes)
