Abstract Data quality in face-to-face interviews might be affected by interviewers' irregular behaviour like intentional deviation from the prescribed interviewing procedures, called cheating or interviewer falsification. As a part of a DFG research project we develop a multivariate statis-tical method - based on the motivation of such cheating behaviour - for ex-post identifica-tion of falsifications in survey data. As a first step in the project we conducted two explorative studies to identify the attributes of questionnaires, which would be useful to identify falsified data. During this step, existing real survey data is compared with “falsified” data which is fabricated by people participating in the explorative study. First results indicate clear differences between falsi-fied and real data. Falsifiers show a higher proportion of denominations of the option “Oth-ers” (in all semi-open questions which offer the option “other”), show less extreme answers in scale questions and they overestimate the political knowledge of real respondents. Fur-ther the falsifiers tend to round their answers to open-ended questions which require a me-tric answer like income or the frequency of a specific behaviour. Also they show higher in-ternal consistencies in item sets which are calculated by means of reliability coefficients. Based on these results we compute for every interviewer some specific “indicators of cheating” which are included in the multivariate analysis. For example we calculate the share of extreme answers in all scale questions or the share of rounded answers in all open-ended questions, and incorporate them in
