Comparison of Patient‐Reported Outcomes Measurement Information System Computerized Adaptive Testing Versus Fixed Short Forms in Juvenile Myositis
Authors' conclusion
PROMIS CAT appears to be feasible and correlated with FSFs. CAT had less pronounced floor/ceiling effects, allowing detection of individual differences in less symptomatic patients.
Study context
- Population
- Patients with juvenile myositis 8–17 years of age (self-report and parent proxy) and parents of patients 5–7 years of age (parent proxy only)patient-parent dyads analysed
- Participants
- 67 patients
- Exposure
- Patient-Reported Outcomes Measurement Information System (PROMIS) computerized adaptive testing vs fixed short forms
- Outcome
- PROMIS fatigue, pain interference, upper extremity function, mobility, anxiety and depressive symptoms: CAT vs FSF mean scores
