Mixed-Mode Contacts In Web Surveys: Paper is Not Necessarily Better

This paper investigates the impact of paper and email contactson web survey response rates. We use six combinations of paperand email prenotifications and reminders to test the impactof mixed-mode contacts. In addition, we use two survey samplesthat differ in their relationship with the sponsoring institutionto test if the impact of contact mode is conditional on relationshipbetween respondents and the survey researchers. Contrary toprevious research, we find little differences in response ratesacross experimental groups.
