TL;DR
Three strategies to increase response rates to mailed physician surveys are assessed: including a $10 versus a $5 cash incentive in the initial mailing, including a mint candy or not, and using a large versus small outgoing envelope.
Abstract
Investigators may increase response rates by including more money in the initial questionnaire packet, but there may be diminishing returns to serial increments in incentives greater than 5 dollars. Including smaller incentives in more questionnaires may maximize total responses.

Although several mail survey techniques are associated with higher response rates, response rates to published mail surveys tend to be moderate, and investigators, journal editors, and readers should devote more attention to assessments of bias, and less to specific response rate thresholds.

It is becoming increasingly difficult to obtain high response rates in physicians' mail surveys, and a handwritten thank you note at the bottom of the letter accompanying the questionnaire and a more personalized mailout package increased response rates.

A $5 bill incentive yielded a higher response rate among the physicians in this study than did a $2 bill incentive, which suggests that resources in a fixed survey budget are allocated more efficiently to increasing the initial incentive rather than to providing a third wave to nonresponders.

Efforts to increase response rates to a mailed physician survey were assessed and whether, as a result, nonresponse bias was reduced and this may not be the case for other studies.

It is found that paper stamps, especially large commemorative stamps, on return envelopes increased the response rate and reduced the response time, as compared with other mailing strategies.

It is concluded that the packaging of a mail survey can influence the response rate and that academic physicians' response rates depend on the envelope used to mail the survey.
