Validity and utility of a single-item patient-reported measure of treatment-related bother in rheumatoid arthritis: A cross-sectional OMERACT study

Semin Arthritis RheumPublished Cross-sectional study

Authors' conclusion

Our results may indicate that individuals have diverse experiences of side effects, allowing the global index to capture these variations, even when they differ across patients.

Study context

Population
Patients with rheumatoid arthritis (RA) reporting symptomatic side effects of RA medications
Participants
560 patients
Outcome
Construct validity of the single-item bother measure (Functional Assessment of Chronic Illness Therapy (FACIT) GP5) vs current symptomatic side effects (Patient-Reported Outcomes of the Common Terminology Criteria for Adverse Events (PROCTCAE))
Methodological detailsweb-based survey, multiple correspondence analysis
  • Web-based survey
  • Multiple correspondence analysis

Main finding

As reported in the abstract

Dimensions of 80 symptomatic side effects (multiple correspondence analysis (MCA))
  • Clear elbow point after the first dimension; one dimension captured the most meaningful information
  • Overall side effect burden score reflected a broad concept influenced by a variety of symptomatic side effects, each with only a negligible to weak impact

Observational data: associations, not effects.
