Sponsor's own description
The objective of this research study is to evaluate a culturally tailored sexual and reproductive health intervention among American Indian (AI) youth. Specifically, the investigators aim to evaluate the impact of "Respecting the Circle of Life: Mind, Body and Spirit" on knowledge, attitude and behavioral outcomes associated with risk for unprotected sex, sexually transmitted infection (STI) and unintended pregnancy through a randomized controlled trial on the White Mountain Apache (WMA) reservation. The investigators will examine whether the RCL intervention effectively reduces risky sexual behavior among AI adolescents (11-19 years old), with long term goals of reducing teen pregnancy and incidence/prevalence of STIs. The evaluation will focus on well-established intermediate outcomes/risky sexual behaviors that predict long-term impact on teen pregnancy and STI incidence.
