PROMIS, Patient-Reported Outcomes Measurement Information System; VSI, Visceral Sensitivity Index.
By design, all PROMIS scales are normed to a score of 50 and s.d. of 10 in the general population using a T-metric.
a
Higher score denotes more gastrointestinal (GI) symptoms.
b
Higher score denotes better health-related quality of life (HRQoL).
c
Higher score denotes more GI-associated visceral sensitivity.
