There is no consensus on how to determine appropriate financial compensation for research recruitment. Selecting incentive amounts that are reasonable and respectful, without undue inducement, remains challenging. Previously, we demonstrated that incentive amount significantly impacts participants' willingness to complete various hypothetical research activities. Here we further explore this relationship in a mock decentralized study.
Adult ResearchMatch volunteers were invited to join a prospective study where interested individuals were given an opportunity to view details for a study along with participation requirements, then offered a randomly generated compensation amount between $0 and $50 to enroll and participate. Individuals agreeing to participate were then asked to complete tasks using a remote mobile application (MyCap), for two weeks. Tasks included a weekly survey, a daily gratitude journal and daily phone tapping task.
Willingness to participate was 85% across all incentive levels but not significantly impacted by amount. Task completion appeared to increase as a function of compensation until a plateau at $25. While participants described the study as low burden and reported that compensation was moderately important to their decision to join, only 31% completed all study tasks.
While offering compensation in this study did not have a strong effect on enrollment rate, this work provides insight into participant motivation when joining and participating in studies employing mobile applications.
对于如何确定合理的研究招募经济补偿尚无共识。选择合理且恰当、不存在过度诱导的激励金额仍然具有挑战性。此前，我们证明了激励金额会显著影响参与者完成各种假设性研究活动的意愿。在此，我们在一项模拟去中心化研究中进一步探究这种关系。
邀请成年ResearchMatch志愿者参与一项前瞻性研究，感兴趣的个体有机会查看一项研究的详细信息以及参与要求，然后提供0美元至50美元之间随机生成的补偿金额以招募其参与。同意参与的个体随后被要求使用远程移动应用程序（MyCap）完成任务，为期两周。任务包括每周一次的调查、每日感恩日记和每日电话录音任务。
在所有激励水平下，参与意愿均为85%，但未受到金额的显著影响。任务完成情况似乎随着补偿增加而上升，直到25美元时趋于平稳。虽然参与者将该研究描述为负担较轻，并表示补偿对他们决定参与的影响适中，但只有31%的人完成了所有研究任务。
虽然本研究中提供补偿对招募率没有显著影响，但这项工作为了解使用移动应用程序的研究中参与者的参与动机提供了见解。
