Reliability and construct validity of PROMIS® measures for patients with heart failure who undergo heart transplant.

ABSTRACT:

Purpose

To evaluate the reliability and construct validity of measures from the Patient-Reported Outcomes Measurement Information System(®) (PROMIS(®)) for patients with heart failure before and after heart transplantation.

Methods

We assessed reliability of the PROMIS short forms using Cronbach's alpha and the average marginal reliability. To assess the construct validity of PROMIS computerized adaptive tests and short-form measures, we calculated Pearson product moment correlations between PROMIS measures of physical function, fatigue, depression, and social function and existing PRO measures of similar domains (i.e., convergent validity) as well as different domains (i.e., discriminate validity) in patients with heart failure awaiting heart transplant. We evaluated the re
