About this trial
This study is a 2-arm cluster randomized controlled trial with approximately 1,200 youth aged 14-19 years to assess the effectiveness of Yes and Know, a sexual health education program. To be eligible, participants must be 14-19 years old and English-speaking. Those in the treatment arm will receive Yes and Know, a synchronous virtual program delivered over multiple sessions totaling nine hours, along with asynchronous online activities and resources. Those in the control arm will receive a similarly structured program focused on nutrition education. Participants will complete brief online surveys at baseline and at 3 and 12 months after the synchronous sessions. The study will assess the program's effectiveness in reducing the prevalence of unprotected sex among youth and improving short-term outcomes, such as knowledge of reproductive health and healthy relationships, self-efficacy, and the use of reproductive health services.
