Short Form 36 (SF-36) health survey questionnaire in health-related quality of life assessment in patients with inflammatory myopathies
Authors' conclusion
SF-36 demonstrated adequate discriminant and construct validity and responsiveness for health-related QoL assessment in patients with IIM.
Study context
- Population
- Adults with idiopathic inflammatory myopathies (IIM) in FORWARD, a US-based databank of biannual patient-reported data on rheumatic diseases77.3% female
- Participants
- 168 adults
- Outcome
- Measurement properties of SF-36 (PCS and MCS, 0-100, higher = better quality of life (QoL)): discriminant and construct validity and responsiveness
Methodological detailsregistry-based (FORWARD databank), longitudinal
- Registry-based (FORWARD databank)
- Longitudinal
Performance
As reported in the abstract
SF-36 measurement properties
- Mean SF-36 PCS
- 36.5 (±11.2)
- Mean SF-36 MCS
- 47.0 (±12.0)
- PCS differed between low vs high physical function, disease activity, fatigue and pain; MCS differed with vs without depression and anxiety, and low vs high fatigue and pain
- p<0.0001
