Objectives: The objective of this meta-analysis was to assess incentive effectiveness on response to electronic health surveys.
Study Design and Setting: A systematic literature search of PubMed, Web of Science, CINAHL, EMBASE, and the Cochrane Library was performed from 1970 to March 2013. Two authors independently selected the trials, assessed methodological quality, and extracted data. Original authors were contacted for the missing information.
Results: The search strategy yielded nine trials (including 29,463 participants in total) that met eligibility criteria. For each of the incentive strategies examined, a random-effects model was used because of significant heterogeneity, and results were summarized as pooled odds ratios (ORs). Compared with no incentive, the offer of an incentive was seen to have a beneficial effect on response (OR, 1.48; 95% CI: 1.29, 1.71). Specifically, the odds of response were more than doubled when a monetary incentive was used (OR, 2.43; 95% CI: 1.60, 3.69) and increased when nonmonetary incentives were used (OR, 1.33; 95% CI: 1.17, 1.51).
Conclusion: These findings indicate that health researchers using electronic surveys can improve the quality of their research by offering incentives to potential participants.
