Short Form-36 psychometric properties in idiopathic inflammatory myopathies: reliability, validity and responsiveness
Authors' conclusion
SF-36 demonstrates good reliability, validity and responsiveness in IIM
Study context
- Population
- IIM patients fulfilling the EULAR/ACR classification criteria or with myositis-specific antibodies (44% DM, 30% ASyS, 18% PM, 8% necrotizing myopathy; mean age 52.3 years, 64% females, 85% White)
- Participants
- 105 patients
- Outcome
- Psychometric properties of SF-36 as an HRQoL measure in IIM: test-retest reliability, validity and responsiveness
Methodological detailspooled data from two clinical trials and one prospective observational study, Data collection at 0, 3 and 6 months, including all myositis core set measures (incl. MMT-8) and SF-36 summary scores and all eight subdomains

Performance
As reported in the abstract
SF-36 reliability, validity and responsiveness
- All SF-36 components: good test-retest reliability at 1 month
