Table 1 Categories for classification of PROMs
Category | Characteristics | Implications |
|---|---|---|
A | Evidence for sufficient content validity (any level) and at least low evidence for sufficient internal consistency | Have potential to be recommended as the most suitable questionnaire for the construct and population of interest |
B | Questionnaire not categorized in A or C | May have the potential to be recommended, but further validation studies are needed |
C | High quality evidence for an insufficient measurement property | Should not be recommended |
