Psychometrics of patient reported outcomes

Frank Doyle, Psychology. Keywords: population health, patient reported outcomes, item response theory, psychometrics.

Patient reported outcomes are a vital part of modern healthcare. However, commonly used measures do not always demonstrate sound psychometric qualities, and could be enhanced by omitting non-performing items. In other cases, the measures should be abandoned and other, more suitable ones adopted.This project will use large databases to assess the psychometrics of such scales, using modern methods such as item response theory and confirmatory factor analysis.
