Postcards are frequently used in mail surveys to increase response rates. Postcards are valuable in that they remind respondents to return their completed questionnaire; notify that a questionnaire had been sent if it was received by a different household member; and can introduce an alternative response option such as a link to a web survey. Reminder postcards are generally followed by a recontact attempt such as a second mailing of the questionnaire packet or a follow-up telephone call. This presentation evaluates the impact of a postcard on a multi-mode survey of rental units in Charleston, SC and Fort Wayne, IN. The survey response options include mail, web, and telephone. This research study is designed to measure the overall increase in survey response due to the postcard and whether the increase in response varies across recontact mode. The results are based on a two factor experimental design with each address assigned to a postcard condition and a recontact condition. The addresses were equally assigned to one of three postcard conditions: no postcard sent, postcard sent with an option to conduct the survey on the web, postcard sent with no mention of the web survey. Independent of the postcard assignment, addresses were assigned to the recontact condition, which included a second mail packet or telephone follow-up.
