Comparing Novel and Legacy Health Assessment Questionnaire Scoring Methods: A Scleroderma Patient-centered Intervention Network Cohort Study

J RheumatolPublished 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.
