This paper describes the conversion from PAPI to CAPI of a subsample of the German Socio-economic Panel (SOEP) and examines the implication of the move to CAPI for data quality. A representative gross-sample E contains 2000 German households and is split into two additional subsamples E1 and E2 with the same structure using twin – sample points. Each of the 125 sample point contains 16 addresses (8 for E1 and 8 for E2) and had to be realized in the first wave alternately with PAPI and CAPI mode per interviewer. In the subsequent waves the PAPI mode is partly replaced by CAPI. With this experimental longitudinal design we are able to control for possible interviewer effects in the analysis of mode effects. The paper assesses whether any mode effects are apparent within the response rate and within the data, we examines monetary amounts like gross income, item and unit nonresponse rates, satisfaction items and the consistency of some key measures. We could find some minor effects but our main results show that we have made the shift without introducing strong mode effects.
