Recruiting older adults (OA) into research is challenging.
To assess the feasibility of using two crowdsourcing platforms, Amazon's Mechanical Turk (MTurk) and Prolific Academic (ProA), as efficient and low-cost venues for recruiting survey participants aged 65 and older.
We developed an online survey to investigate and compare the demographics, technology use, and motivations for research participation of OA on MTurk and ProA. Qualitative responses, response time, word count, and recruitment costs were analyzed.
We recruited 97 OA survey participants on both MTurk and ProA. Participants were similar in terms ofdemographics, technology usage, and motivations for participation (topic interest and payment).
Both crowdsourcing platforms are useful for rapid and low-cost recruitment of OA. The OA recruitment process was more efficient with ProA. Crowdsourcing platforms are potential sources of OA research participants; however, the pool is limited to generally healthy, technologically active, and well-educated older adults.
招募老年人（OA）参与研究具有挑战性。
评估两种众包平台（亚马逊的 Mechanical Turk（MTurk）和 Prolific Academic（ProA））作为招募 65 岁及以上调查参与者的高效且低成本场所的可行性。
我们开发了一项在线调查，以调查和比较 MTurk 和 ProA 上的 OA 的人口统计学、技术使用情况和参与研究的动机。分析了定性回复、回复时间、字数和招募成本。
我们在 MTurk 和 ProA 上都招募了 97 名 OA 调查参与者。参与者在人口统计学、技术使用和参与动机（主题兴趣和报酬）方面相似。
两种众包平台都可用于快速且低成本地招募 OA。ProA 的 OA 招募过程更高效。众包平台是 OA 研究参与者的潜在来源；然而，参与者群体仅限于一般健康、技术活跃和受过良好教育的老年人。
