Summary

This study tests whether the WhatsOK helpline can help teens aged 14-17 who are worried about their sexual thoughts or behaviors. Participants will be randomly assigned to use the helpline or not, and researchers will track whether they seek other support and whether they engage in harmful sexual behaviors. The goal is to see if a confidential helpline can prevent problems before they start.

What this could mean

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

Active substance
WhatsOK helpline (behavioral intervention)
What this could lead to
If it works, this could provide an effective, confidential helpline that helps teens avoid harmful sexual behaviors and get the right support early.
What could go wrong
This is an early-stage trial with no prior efficacy data. The results depend on teens actually using the helpline and reporting honestly, which may not reflect real-world use.
