The Evaluation of Pulse: A Mobile Health App and Teen Pregnancy Prevention Program
NCT04043130 · View on ClinicalTrials.gov ↗
Study Summary
This study used a randomized controlled design to evaluate the efficacy of a new mobile app, Pulse, in reducing the incidence of unprotected sex among young women. Pulse is a web-based mobile health application that can be accessed through mobile smartphones and computers. Pulse was designed to increase highly effective birth control use and reproductive and sexual health care utilization, and ultimately decrease teen pregnancy. The sample was comprised of 2,317 women aged 18-20 who, at enrollment, were not pregnant or trying to become pregnant, had daily access to a smartphone, were currently living in the United States or a U.S. territory, and spoke English. Most of the sample (86%) identified as Black and/or Latinx. The evaluation team enrolled participants over a two and a half year enrollment period using social media, including Facebook and Instagram. Users accessed Pulse autonomously, on their own terms, and in their own time and place. The app consists of 6 sections and includes 3 hours of unique content. It does not require the user to follow a specific sequence of content viewed; however, all users received a monetary incentive after registering with the app. Young women randomized to the intervention condition were given access to Pulse indefinitely and received daily text messages related to sexual health for 6 weeks. Control participants were directed to a free general health/fitness web-based mobile application, also called Pulse, and received text messages related to general health for 6 weeks. The control and treatment apps look and feel similar aesthetically but contain different content. Participants in both the intervention and comparison groups received a baseline survey, a 6-week follow-up survey, and a 6-month follow-up survey (the 6-month follow-up survey was only administered to participants recruited between November 2018 and March 2019). Participants also received incentives for completing the baseline and post-intervention surveys. Both s

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04043130
The ClinicalTrials.gov registry entry for NCT04043130 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 2,317 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Child Trends, which has 7 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Contraceptive Usage appearing as the primary indexed condition, and to 1 intervention — of which Pulse is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04043130 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
