Mail Surveys Using Dillman's TDM in a Southern European Country: Spain
The Department of Sociology of the Public University of Navarra.
Dillman's Total Design Method (TDM), applied in mail surveys, has produced excellent results in several countries around the world, but as far as we can gather it has never been used in any southern European country. The results obtained from mail surveys in the United States, and some of the studies done by disciples of Dillman in several European countries, encouraged us to carry out the first investigation in Spain using the TDM for mail surveys. The scant use of mail surveys in Spain and the experience of various marketing firms made us expect that (1) a mail survey in Spain would not yield a response rate above 40 percent, and (2) that the use of TDM should notably increase the response rate, reaching a level similar to other countries. A mail survey in Navarra achived a response rate much higher than the expected 40 percent, and TDM did indeed increase response.
