Patient Perceptions of CT Imaging in a Diverse Patient Sample

Survey Research in Radiology: “Strongly Agree”

“…Here, the sampling method is simple: ask them all, and try to get 100% to participate. In other cases, the potential population is much broader, as in Lind et al's inquiry into patient opinions of CT at an outpatient imaging center [3]. Because the authors had particular interest in the opinions of members of underrepresented minority groups, they anticipated the need to oversample members of these groups to achieve a match between their final sample and their population of interest.…”

“…Ideally, formal pretesting and evaluation for internal reliability should be performed when new items are generated, as Yin and colleagues described in detail in their investigation of physician opinions on optimal reporting of multipart imaging examinations [14]. Lind et al also used a hybrid approach incorporating both validated and new items and then performed statistical validation of their entire survey [3]. However, we analyzed recent survey research in radiology and noted that less than half of such publications in 2017 to 2018 either used a validated instrument or reported rigorous pretesting [15], suggesting the need for improvement.…”
