Electronic dating violence is a form of violence perpetrated through electronics between dating partners and is associated with worse mental health, greater risk of substance use, and increased risk of in-person forms of dating violence. Though prevalent and seeming to increase in occurrence across adolescence, little is known about trajectories of electronic dating violence throughout adolescence and both risk and protective factors predicting a given trajectory. Latent growth models were used to evaluate change over time in three specific domains of electronic dating violence: harassment, coercion, and monitoring. Data are drawn from two cohorts who were surveyed annually for four years (2013–2017) from age 12 to 15 (n = 543; 48.3% female) and 15 to 18 (n = 597, 46.6% female), respectively. For all three domains of electronic dating violence, a quadratic model fit best. In general, electronic dating violence increased from early adolescence until a peak around age 16 or 17, and then leveled off. Threat-based adverse childhood experiences (i.e., exposure to physical child abuse, parental intimate partner violence, etc.) and earlier engagement in dating behaviors increased long-term risk for both age cohorts. Protective factors such as parental monitoring decreased risk but seemed to only have protective influence at developmentally-specific periods (i.e., during the developmental period of early adolescence). A better understanding of the risk and protective factors that affect the increase of electronic dating violence during adolescence is necessary to develop effective age-appropriate prevention and intervention strategies for youth.

电子约会暴力是约会对象之间通过电子设备实施的一种暴力形式，与更差的心理健康、更大的物质使用风险以及增加面对面形式的约会暴力的风险有关。尽管在整个青春期普遍存在并且似乎在增加，但人们对电子约会暴力在整个青春期的轨迹以及预测给定轨迹的风险和保护因素知之甚少。潜在增长模型用于评估电子约会暴力的三个特定领域随时间的变化：骚扰、胁迫和监控。数据来自两个队列，他们每年接受为期四年（2013-2017）的调查，年龄从 12 岁到 15 岁（n  = 543；48.3% 是女性）和 15 到 18 岁（n = 597，女性占 46.6%）。对于电子约会暴力的所有三个领域，二次模型最适合。一般来说，电子约会暴力从青春期早期开始增加，直到 16 或 17 岁左右达到顶峰，然后趋于平稳。基于威胁的不良童年经历（即儿童遭受身体虐待、父母亲密伴侣暴力等）和早期参与约会行为增加了两个年龄段的长期风险。父母监护等保护性因素降低了风险，但似乎仅在发育特定时期（即青春期早期的发育期）具有保护性影响。
