Research DEFECT I - Design effects in complex surveys

Goal of the project was the empirical estimation of factual standard errors in a complex survey of the general population in Germany. We tried to separate the effects of  inverviewers, field organizations [house effects], sampling points [PSUs] and data collection mode by an interpenetrated sample design of five national surveys with 160 PSUs in a fear of crime survey. More details on the design can be found in Schnell/Kreuter (2002, in German) and Schnell/Kreuter (2005) in English.
