Abstract

"This report documents a specific case of interviewer falsification in the IAB job survey, the subsequent revision of the data and the new data quality concept. In the specific case, two interviewers with falsified interviews were identified in the period lasting from Q1 2020 to Q2 2021. All interviews of the falsifying interviewers were retrospectively deleted from the microdata. Publications on the aggregated number of vacancies that are scheduled 44 days after the end of the quarter were revised. In light of the discovered falsification of interviews, additional measures were introduced to detect and prevent such falsifications at an early stage. These measures include limiting the maximum number of interviews per interviewers, improved training and supervision of interviewers, more intensive evaluation of interviewers' audio files, and most importantly, the introduction of a paradata-based dashboard for more systematic and regular monitoring of interviewers."
