Teen dating violence is a serious public health problem with few effective prevention strategies. This study examines whether the Dating Matters comprehensive prevention model, compared with a standard of care intervention, prevented negative relationship behaviors and promoted positive relationship behaviors.
This longitudinal, cluster-RCT compared the effectiveness of Dating Matters with standard of care across middle school. Standard of care was an evidence-based teen dating violence prevention curriculum (Safe Dates) implemented in eighth grade.
SETTING/PARTICIPANTS: Forty-six middle schools in high-risk urban neighborhoods in four U.S. cities were randomized. Schools lost to follow-up were replaced with new schools, which were independently randomized (71% school retention). Students were surveyed in fall and spring of sixth, seventh, and eighth grades (2012-2016). The analysis sample includes students from schools implementing Dating Matters or standard of care for >2 years who started sixth grade in the fall of 2012 or 2013 and had dated (N=2,349 students, mean age 12 years, 49% female, and 55% black, non-Hispanic, 28% Hispanic, 17% other).
Dating Matters is a comprehensive, multicomponent prevention model including classroom-delivered programs for sixth to eighth graders, training for parents of sixth to eighth graders, educator training, a youth communications program, and local health department activities to assess capacity and track teen dating violence-related policy and data.
Self-reported teen dating violence perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills were examined as outcomes. Imputation and analyses were conducted in 2017.
Latent panel models demonstrated significant program effects for three of four outcomes; Dating Matters students reported 8.43% lower teen dating violence perpetration, 9.78% lower teen dating violence victimization, and 5.52% lower use of negative conflict resolution strategies, on average across time points and cohorts, than standard of care students. There were no significant effects on positive relationship behaviors.
Dating Matters demonstrates comparative effectiveness, through middle school, for reducing unhealthy relationship behaviors, such as teen dating violence and use of negative conflict resolution strategies, relative to the standard of care intervention.

青少年恋爱暴力是一个严重的公共卫生问题，目前几乎没有有效的预防策略。本研究旨在探讨恋爱关系问题综合预防模式（Dating Matters）与常规护理干预相比，是否能预防负面的恋爱关系行为并促进积极的恋爱关系行为。
这是一项纵向、集群随机对照试验，比较了中学阶段恋爱关系问题综合预防模式与常规护理的效果。常规护理是一种基于证据的青少年恋爱暴力预防课程（Safe Dates），在八年级实施。
研究地点/参与者：来自美国四个城市高风险城市社区的 46 所中学被随机分组。失去随访的学校被新学校取代，新学校是独立随机分组的（71%的学校保留率）。学生在六年级、七年级和八年级的秋季和春季进行调查（2012-2016 年）。分析样本包括在 2012 年秋季或 2013 年秋季开始上六年级、接受过恋爱关系问题综合预防模式或常规护理超过 2 年的学生（N=2349 名学生，平均年龄 12 岁，49%为女性，55%为非裔美国人，28%为西班牙裔，17%为其他族裔）。
恋爱关系问题综合预防模式是一个综合性的多组分预防模式，包括针对六年级至八年级学生的课堂教学计划、六年级至八年级学生家长培训、教育者培训、青年沟通计划以及地方卫生部门评估能力和跟踪青少年恋爱暴力相关政策和数据的活动。
自我报告的青少年恋爱暴力实施和受害、使用消极冲突解决策略以及积极的恋爱关系技能被视为结果。在 2017 年进行了插补和分析。
潜在面板模型显示，在四个结果中有三个存在显著的项目效果；与常规护理学生相比，恋爱关系问题综合预防模式的学生报告称，平均而言，在整个时间点和队列中，青少年恋爱暴力实施减少了 8.43%，青少年恋爱暴力受害减少了 9.78%，消极冲突解决策略的使用减少了 5.52%。但对积极的恋爱关系行为没有显著影响。
通过中学阶段，恋爱关系问题综合预防模式相对于常规护理干预，在减少青少年恋爱暴力和使用消极冲突解决策略等不健康的恋爱关系行为方面显示出了比较效果。
