PROMIS Instruments Correlate Better with Legacy Measures in Knee Cartilage Patients at Post-operative than at Pre-operative Assessment
PURPOSE: To define the psychometric properties of the PROMIS Physical Function (PF), Pain Interference (PI) and Depression Computer Adaptive Test (CAT) in patients undergoing knee cartilage surgeries.
METHODS: The PROMIS PF, PI and Depression CAT were administered preoperatively and at 6 months alongside legacy knee patient-reported outcome measures in patients undergoing knee cartilage surgeries. Statistical analysis consisted of time-to-completion, psychometric analysis for correlative strengths, absolute and relative floor and ceiling effects, and Cohen's effect size.
