Industrial mail surveys - A methodological update

This study reports on the experimental studies investigating methods of improving industrial mail survey rates since a 1986 review. These later studies confirm the effectiveness of monetary incentives, the use of return stamps, and the granting of anonymity when sensitive information is requested. The also provide insights into new effects such as the use of telephone prenotification, express mail, using university letter-heading and telephone reminders. The period is also notable for the growth in experimental findings from cross-national industrial mail surveys. These results are also reported. (C) 1998 Elsevier Science Inc.
