Research RAT - Refusal avoidance training
Based on Groves/McGonagle (2001) and interviewer manuals of the "Survey Research Center" (Michigan) instructional materials of a German "Refusal Avoidance Training" (RAT) has been developed by our group. The goal of a RAT is reducing refusal rates by teaching interviewers how to deal with doorstep interactions by maintaining interaction with the respondents and tailoring the arguments to them. The RAT-Training was developed for in person teaching of face-to-face interviewers and as a multimedia self-teaching unit for CATI-interviewers.
The RAT-training has been used for interviewer training in two studies in Germany: For training of face-to-face-interviewers in the German-ESS-Wave 2 (n=5883) and for training of telephone interviewers in the new German "Panel Study Labour Market and Social Security" (n = 12000). In both studies quasi experimental designs were used to compare final disposition codes between trained and untrained interviewers. The data indicate that RAT-trained interviewers generate significantly fewer refusals, but a part of this nonresponse reduction is compensated by an increase in other nonresponse categories. Nevertheless, a RAT-Training reduced refusal rates in both studies.
