Official title

The Share Health Study: Teens Social Connections and Health (Phase 2)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to determine whether delivery of SpeakOut, a behavioral intervention to increase social communication about long-acting reversible contraceptive (LARC) methods among adolescents, is associated with increased contraceptive use among the social contacts of SpeakOut recipients. The investigators will conduct a cluster randomized controlled trial of SpeakOut with adolescent LARC users and their female peers. Over three years, SpeakOut will be implemented in eight partner clinics. IUD and implant users aged 15 to 19 will be recruited online and invited to enroll in the evaluation study as "primary" participants and receive either SpeakOut or a control intervention about alcohol use called PartyWise. The social contacts of primary participants will be asked to enroll in the study as "secondary" participants. The study's primary outcome will be the proportion of sexually-active secondary participants who are using any contraceptive method at 9-month follow-up.
