The objective of this meta-analysis was to assess incentive effectiveness on response to electronic health surveys.
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.
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).
These findings indicate that health researchers using electronic surveys can improve the quality of their research by offering incentives to potential participants.
本荟萃分析旨在评估激励措施对电子健康调查响应的效果。
从 1970 年至 2013 年 3 月，对 PubMed、Web of Science、CINAHL、EMBASE 和 Cochrane 图书馆进行了系统的文献检索。两位作者独立选择试验、评估方法学质量并提取数据。对于缺失的信息，联系了原始作者。
搜索策略产生了 9 项试验（共纳入 29463 名参与者），符合入选标准。由于存在显著的异质性，对于每种检查的激励策略，均采用随机效应模型，汇总结果为汇总优势比（OR）。与无激励相比，提供激励对响应有有益的影响（OR，1.48；95%CI：1.29，1.71）。具体而言，当使用金钱激励时，响应的几率增加了一倍以上（OR，2.43；95%CI：1.60，3.69），当使用非金钱激励时，响应的几率增加（OR，1.33；95%CI：1.17，1.51）。
这些发现表明，使用电子调查的健康研究人员可以通过向潜在参与者提供激励来提高其研究的质量。
