To determine the impact of Positive Prevention PLUS, a school-based adolescent pregnancy prevention program on delaying sexual intercourse, birth control use, and pregnancy.
I randomly assigned a diverse sample of ninth grade students in 21 suburban public high schools in California into treatment (n = 2483) and control (n = 1784) groups that participated in a clustered randomized controlled trial. Between October 2013 and May 2014, participants completed baseline and 6-month follow-up surveys regarding sexual behavior and pregnancy. Participants in the treatment group were offered Positive Prevention PLUS, an 11-lesson adolescent pregnancy prevention program.
The program had statistically significant impacts on delaying sexual intercourse and increasing the use of birth control. However, I detected no program effect on pregnancy rates at 6-month follow-up.
The Positive Prevention PLUS program demonstrated positive impacts on adolescent sexual behavior. This suggests that programs that focus on having students practice risk reduction skills may delay sexual activity and increase birth control use.
确定“积极预防加强版”（一项以学校为基础的青少年怀孕预防项目）对推迟首次性行为、使用节育措施和怀孕的影响。
我将加利福尼亚州21所郊区公立高中的九年级学生的多样化样本随机分为治疗组（n = 2483）和对照组（n = 1784），两组参与了一项整群随机对照试验。在2013年10月至2014年5月期间，参与者完成了关于性行为和怀孕的基线调查以及6个月的随访调查。治疗组的参与者接受了“积极预防加强版”，这是一个包含11节课的青少年怀孕预防项目。
该项目在推迟首次性行为和增加节育措施使用方面具有统计学上的显著影响。然而，在6个月的随访中，我未发现该项目对怀孕率有影响。
“积极预防加强版”项目对青少年性行为产生了积极影响。这表明专注于让学生实践降低风险技能的项目可能会推迟性活动并增加节育措施的使用。
