Systemic sclerosis & Raynaud's
Comparing Novel and Legacy Health Assessment Questionnaire Scoring Methods: A Scleroderma Patient-centered Intervention Network Cohort Study
Authors' conclusion
Its association with external measures, however, did not differ from the standard HAQ-DI.
Study context
- Population
- SPIN Cohort participants with systemic sclerosis (SSc) completing the Health Assessment Questionnaire (HAQ) (20 items, 8 domains) at enrollment
- Exposure
- Item response tree (IRTree)-based HAQ scoring vs HAQ-Disability Index (HAQ-DI), HAQ-Alternative Disability Index (HAQ-ADI), modified HAQ (mHAQ) and summed scores
- Outcome
- Convergent validity with physical function, pain interference and hand function (Pearson correlations)
- Follow-up
- Enrollment
Methodological detailsmeasurement comparison, Pearson correlations
- Measurement comparison
- Pearson correlations
Main finding
As reported in the abstract
Convergent validity (Pearson correlations)
IRTree-based scores correlated with other scoring procedures
r 0.90-0.95
IRTree-based scores correlated with all external measures (moderate-to-strong)
r 0.68-0.80
Observational data: associations, not effects.
