Summary

This trial tests whether a mobile app called Girls helps adolescent girls feel more confident talking about sexual health with their partners. Researchers will compare girls who use the app to those who do not, measuring communication confidence and other sexual health outcomes. The study includes 245 girls aged 15 to 24 who use smartphones. The goal is to see if a simple app can make a real difference in how young women approach these important conversations.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A mobile application called Girls designed to support sexual communication
What this could lead to
If the app works, it could give adolescent girls a practical tool to feel more confident discussing sexual health with partners, potentially improving their sexual health outcomes.
What could go wrong
This is a single study with a specific group of girls, so results may not apply to everyone. The app's effect may be limited or not lasting beyond the study period.
