Research output: Chapter in Book/Report/Conference proceedingChapter


The validity of a PRO measure encompasses the evaluative judgement of the degree to which empirical evidence and theoretical rationales support the trustworthiness of interpretations and actions based on scale scores (Messick 1988). Such score inferences might be specific to a particular context of use. Although a distinction is often made between content validity, criterion validity and construct validity, these are interdependent and generally reflect different forms of evidence supportive of the credibility, accuracy and dependability of a measure—embodying a holistic concept of construct validity (Streiner and Norman 2008).
