Abstract

OBJECTIVES

To test the effects of the Safer Sex Intervention (SSI) on female adolescents' sexual behavior and possible antecedents of behavior such as sexual health attitudes, knowledge, motivation, intentions, and skills.

METHODS

A randomized controlled trial compared SSI (n = 1196) with no intervention (n = 613) among female adolescents aged 13 to 20 years at 3 sites across the United States from 2012 to 2015. Intent-to-treat impacts were estimated at 9 months after baseline, overall, and for key subgroups.

RESULTS

Compared with control participants, SSI participants were less likely to have sexual intercourse without birth control, more likely to report positive attitudes toward protection and intention to use condoms, and more confident of their ability to refuse sex. SSI did not affect sexual risk knowledge or motivation to delay childbearing. Positive impacts on sexual behavior and sexual risk were observed among key subgroups of youths who were aged 18 years or older, Hispanic, not sexually experienced at baseline, and enrolled at the Minnesota site.

CONCLUSIONS

SSI produced meaningful changes in sexual behavior and sexual risk and successfully addressed some potential antecedents of sexual risk behavior.

摘要

目的

测试安全性行为干预（SSI）对女性青少年性行为以及性行为可能的前因，如性健康态度、知识、动机、意图和技能的影响。

方法

2012年至2015年期间，在美国3个地点对13至20岁的女性青少年进行了一项随机对照试验，将SSI组（n = 1196）与无干预组（n = 613）进行比较。在基线后9个月对总体及关键亚组进行意向性治疗影响评估。

结果

与对照组参与者相比，SSI组参与者在未采取避孕措施的情况下进行性交的可能性较小，更有可能报告对保护措施持积极态度并打算使用避孕套，并且对自己拒绝性行为的能力更有信心。SSI对性风险知识或延迟生育的动机没有影响。在18岁及以上、西班牙裔、基线时无性行为经历且在明尼苏达地点入组的青少年关键亚组中，观察到对性行为和性风险有积极影响。
