Validation of PROMIS Pain Interference Banks in Patients With RA

Both Patient-Reported Outcomes Measurement Information System Pain Interference (PROMIS-PI) and PROMISE-Pain Behavior (PROMISE-PB) demonstrated good psychometric properties in patients with rheumatoid arthritis (RA), a new study found. 2,029 patients with RA completed the full PROMISE-PI and 1,554 patients the full PROMIS-PB. Researchers found:

  • The PROMIS-PI and PROMIS-PB banks were sufficiently unidimensional, had negligible local dependence, good monotonicity, and a good Graded Response Model (GRM) fit.
  • Both item-banks showed good cross-cultural validity, measurement invariance, good construct validity, high reliability, and absence of floor and ceiling effects.
  • Both PROMISE-PI and PROMIS-PB can be used in research and clinical practice.
