Prime Time: Health Promotion for Multiple Risk Behaviors

描述（由申请人提供）：黄金时间：促进多种危险行为的健康是一项为期五年的干预研究（2005-2009），其总体目标是在早孕高风险的少女中设计、实施和评估一项多成分干预措施，以减少少女怀孕的多种前兆，包括性冒险、暴力参与和辍学。Prime Time的目标是在明尼阿波利斯/圣保罗上学和社区诊所符合特定风险标准的13-17岁女孩（n=250）。采用实验设计，一半的研究参与者被随机分配到干预条件；一半被分配到控制条件。干预参与者将参与黄金时段干预18个月，而对照组参与者将继续接受常规的诊所服务。将在研究基线和研究入组后6、12、18、24和30个月收集所有研究参与者的自我报告数据（通过A-CASI调查）。为了解决与性风险行为、暴力参与和与学校脱节相关的核心风险和保护因素，黄金时间干预采用了一种创新的组合，包括一对一的案例管理、同伴教育（及时）和服务学习（It's Our Time）经验。这种多组分干预措施在Prime Time试点研究中得到了开发和现场测试。采用多波数据评估干预对参与者性风险承担和避孕行为的影响；学校联系、学校不当行为和学校表现；暴力参与和同伴攻击。我们还测试了干预对结果行为的影响在多大程度上是由黄金时段干预的假设风险和保护因素介导的。如果干预措施在预防危险行为方面取得成功，我们将积极参与宣传工作，影响为少女服务的初级保健诊所的最佳做法。

DESCRIPTION (provided by applicant): Prime Time: Health Promotion for Multiple Risk Behaviors is a five-year intervention research study (2005-2009) with an overall goal to design, implement and evaluate a multi-component intervention among adolescent girls at high risk for early pregnancy that reduces multiple precursors of teen pregnancy including sexual risk taking, violence involvement, and school disconnection. Prime Time targets 13-17 year old girls (n=250) attending school and community clinics in Minneapolis/St Paul who meet specified risk criteria. Using an experimental design, half of study participants are randomly assigned to the intervention condition; half are assigned to the control condition. Intervention participants will be involved with the Prime Time intervention for an 18-month period, while control participants will continue to receive usual clinic services. Self-report data will be collected (via A-CASI surveys) from all study participants at study baseline and at 6, 12, 18, 24, and 30 months following study enrollment. To address core risk and protective factors related to sexual risk behaviors, violence involvement, and school disconnection, the Prime Time intervention employs an innovative combination of previously-tested approaches including one-on-one case management, peer education (Just In Time) and service learning (It's Our Time) experiences. This multi-component intervention was developed and field-tested in the Prime Time pilot study. Using multi-wave data, we evaluate intervention impacts on participants' sexual risk taking and contraceptive behaviors; school connectedness, school misbehavior and school performance; violence involvement and peer-related aggression. We also test the extent to which intervention effects on outcome behaviors are mediated by hypothesized risk and protective factors targeted for change by the Prime Time intervention. If the intervention demonstrates success in preventing risk behaviors, we will actively engage in dissemination efforts to affect best practices in primary care clinics serving adolescent girls.
