This included the PROMIS Global Health SF V.1.1, PROMIS Physical Function SF 8b V.1.2, PROMIS Pain Interference SF 8a V.1.0, PROMIS Applied Cognition Abilities SF 8a V.1.0, and PROMIS Sleep Disturbance SF 4A V.1.0, respectively. Scores from each assessment were converted to a T-score for analysis with a mean of 50 and a standard deviation of 10, with lower scores on the PROMIS Pain Interference SF and PROMIS Sleep Disturbance SF considered better, whereas higher scores on all other assessments were considered better.
