Background Recruiting a hidden population, such as the population of women at risk for alcohol-exposed pregnancy (AEP) who binge drink and are at risk of an unintended pregnancy, is challenging as this population is not typically seeking help or part of an identifiable group. We sought to identify affordable and efficient methods of recruitment for hidden populations. Methods Several popular online social media and advertising sites were identified. Cities with high rates of binge drinking among women were targeted. We placed advertisements and study notices using Facebook, Twitter, Craigslist, University postings, and ClinicalTrials.gov. Results For this study, 75 women at risk for AEP were recruited from across the U.S. within 7 months. Online advertising for study participants on Craigslist resulted in enrollment of the majority 51 (68%) of the study participants. While Craigslist advertising could be tailored to specific locations with high rates of binge drinking among women, there were challenges to using Craigslist. These included automated deletion due to repeated postings and mention of sexual behavior or drinking, requiring increased efforts and resources by the study team. Several strategies were developed to optimize advertising on Craigslist. Approximately 100 h of staff time valued at $2500 was needed over the 7-month recruitment period. Discussion Despite challenges, the target sample of women at risk for AEP was recruited in the 7 month recruitment period using online advertising methods. We recommend that researchers consider online classified advertisements when recruiting from non-help seeking populations. By taking advantage of national data to target specific risk factors, and by tailoring advertising efforts, it is possible to efficiently and affordably recruit a non-treatment seeking sample.

在线招募非求助样本进行互联网干预:在酒精暴露怀孕风险降低研究中的经验教训。

背景 招募隐藏的人群,例如酗酒和有意外怀孕风险的酒精暴露怀孕 (AEP) 风险的女性人群,具有挑战性,因为该人群通常不寻求帮助或属于可识别的群体. 我们试图为隐藏人群确定负担得起且有效的招募方法。方法 确定了几个流行的在线社交媒体和广告网站。女性酗酒率高的城市成为目标。我们使用 Facebook、Twitter、Craigslist、大学帖子和 ClinicalTrials.gov 发布广告和研究通知。结果 本研究在 7 个月内从美国各地招募了 75 名有 AEP 风险的女性。Craigslist 上针对研究参与者的在线广告导致大多数 51 (68%) 的研究参与者注册。虽然 Craigslist 广告可以针对女性酗酒率较高的特定地点进行定制,但使用 Craigslist 存在挑战。其中包括由于重复发布和提及性行为或饮酒而自动删除,这需要研究团队增加努力和资源。制定了几种策略来优化 Craigslist 上的广告。在 7 个月的招聘期间,大约需要 100 小时的员工时间,价值 2500 美元。讨论 尽管存在挑战,但在 7 个月的招募期内,使用在线广告方法招募了有 AEP 风险的女性目标样本。我们建议研究人员在从非求助人群中招募时考虑在线分类广告。通过利用国家数据来针对特定的风险因素,并通过定制广告工作,可以有效且经济地招募非寻求治疗的样本。
