abstract = {The implementation of a Refusal Avoidance Training (RAT) within wave
2 of the German part of the European Social Survey (ESS) successful
reduced the amount of reported refusal by nearly 7%. The effect of
the reduction was compensated by a nearly equal increase in the proportion
of non-contacted designated respondents. This effect may be due to
non-random allocation of trained interviewers. Further randomized
experiments are neccessary to separate the effects of RAT on response
rates.},
