Quizplus · Accepted Answer

Offering an incentive has been shown to increase response rates in mail interviews. This can include a small gift or monetary compensation for completing the survey. Pre-notification and first-class mail can also have a positive impact, but offering an incentive is typically the most effective method. Using colored questionnaires is not likely to have a significant effect on response rates.
