The American Medical Association has specific recommendations for its authors about questionnaire response rates included in the JAMA Instructions for Authors. One of the guidelines is that survey studies should have sufficient response rates (generally at least 60%) and appropriate characterization of nonresponders to ensure that nonresponse bias does not threaten the validity of the findings. However, response rates to questionnaires have been declining over the past 20 years, as reported by the Pew Research Center in The Problem of Declining Response Rates. Fortunately, suggestions about increasing questionnaire response rates are available in two recent AEA365 blog posts that are open access:
- Jessica Foster on Maximizing Survey Response Rates: make the questionnaire matter and personalize your communications to the members of your sample;
- Steve Young on Making Evaluation Surveys More Appealing: make responding more fun by using meaningful graphics and new rating tools such as graphic sliders.
Additional useful advice, such as making questionnaires short, personalizing your mailings, and sending full reminder packs to nonrespondents, is included in this open access article: Sahlqvist S, et al., “Effect of questionnaire length, personalisation and reminder type on response rate to a complex postal survey: randomised controlled trial.” BMC Medical Research Methodology 2011, 11:62.
