Comparison of different rating scales for the use in Delphi studies: different scales lead to different consensus and show different test-retest reliability.

ABSTRACT:

Background

Consensus-orientated Delphi studies are increasingly used in various areas of medical research using a variety of different rating scales and criteria for reaching consensus. We explored the influence of using three different rating scales and different consensus criteria on the results for reaching consensus and assessed the test-retest reliability of these scales within a study aimed at identification of global treatment goals for total knee arthroplasty (TKA).
