Abstract

Increasing cost pressure has resulted in fewer population surveys being conducted with interviewer-administered survey modes (CAPI, CATI) and increasingly in cheaper self-administered survey modes (PAPI/CAWI). But also changes in the coverage of individual collection modes may suggest a mode change. Especially with existing panels, however, a mode change is potentially problematic, since mode-specific effects on response behavior and data quality are possible. However, in order to identify and quantify the effects of a mode change, an experimental design is necessary which, among other things, allows the type and extent of error sources (non-response, measurement error) to be analyzed. Such an experimental design is planned for the fourth wave of the Linked Personnel Panel (LPP). This study could identify potential savings if the findings show that a mode change from interviewer-administered mode CATI to the less expensive self-administered mode of CAWI can be carried out without significant quality losses.
