Randomized trial of use of a monetary incentive and a reminder card to increase the response rate to a mailed health survey.
Insufficient response rates are a frequent problem in mailed epidemiologic health surveys.
As part of a health survey of 1,235 young adults conducted from November 1992 through January 1993 in Geneva, Switzerland, a randomized factorial trial was carried out to assess the contributions of two tactics to increase response rates.
The first incentive was the promise of sending 10 Swiss francs (7 US dollars) to respondents; the second was a red postcard, mailed 2 days after the questionnaire, which reminded potential participants to complete the questionnaire.
The most effective strategy according to interim analysis was to be selected for follow-up mailings.
