Since 2016, Child Trends has collaborated with Healthy Teen Network to evaluate Pulse, a web-based mobile health app designed for Black and Latinx women ages 18–20. Through culturally responsive and engaging content, Pulse provides its audience with information on birth control, healthy relationships, sexual health and physiology, pregnancy, and utilization of clinical services. The content is designed to help women who do not want to become pregnant choose effective birth control, seek reproductive health services, and, ultimately, prevent unplanned pregnancies.
- Online recruitment is an innovative and cost-effective way to reach potential participants for research studies. Through social media advertisements, researchers can recruit from a large and diverse population. However, without the face-to-face interactions and personal follow-ups that traditional recruitment methods employ, online recruitment efforts may have difficulty building the trust and credibility needed to get sufficient numbers of eligible potential study participants to complete the enrollment process. This blog offers tips for researchers on how to recruit their desired sample size using online enrollment.
- This research brief highlights the characteristics of women who participated in the Pulse program, their differing levels of engagement with the mobile app, and the characteristics of the participants who engaged with the app versus those who had little or no engagement. Results provide important lessons about the types of young women who can be effectively reached through a solely tech-based pregnancy prevention program.
- Many existing health programs and interventions reach only a portion of the population in need. As a result, practitioners increasingly use tech-based interventions to deliver services to hard-to-reach populations. Because mobile devices are becoming universal, innovative service delivery methods can use mobile apps and text messaging to effectively reach some of these historically hard-to-reach groups—particularly older teens and young adults. This blog discusses the importance of continuously improving user experience with these types of interventions.
Blog – Identifying scammers in online studies
- AEA 365 blog. Health interventions have increasingly incorporated technology components, sometimes even using technology to recruit participants. Identifying suspicious accounts can be a difficult, time-consuming process for online interventions—but it’s also a necessary one. Study teams involved in similar online interventions are encouraged to consider the tips presented in this blog when developing study procedures.
- Healthy Teen Network blog. This blog post builds on the content in the AEA 365 blog, diving deeper into avoiding scammers in online studies. Such studies present unique advantages, including the needs to be cost-efficient, provide researchers with a large recruitment pool, and allow participants to remain anonymous. However, ensuring that participants are who they claim to be represents a challenge that accompanies this form of recruitment. This blog addresses the issue by presenting tips from an evaluation of a strictly technology-based intervention.
- This resource introduces the Pulse intervention and describes Child Trends’ unique approach to evaluating Pulse’s impact on pregnancy among older teens. For this intervention, Child Trends recruited a sample of more than 2,300 young women completely online. The study team was able to retain most of these women for the duration of the intervention and post-test survey administration by using both the app and pre-programmed, automatically delivered text messages.
