From: Satisfaction and experience with colorectal cancer screening: a systematic review of validated patient reported outcome measures

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
