Does PROMIS CAT show better validity and reliability compared to SF-12 in patients with advanced chronic kidney disease?
PROMIS CATs demonstrate sufficient validity and superior reliability compared to SF-12 for measuring patient-reported outcomes in advanced chronic kidney disease.
PROMIS CATs showed sufficient construct validity and test-retest reliability in patients with advanced chronic kidney disease. PROMIS CATs required more items but showed better reliability than the SF-12. Future research is needed to investigate the feasibility of PROMIS CATs for routine nephrology care.
