Dating violence is often perpetrated among adolescents, which increases the efforts to better understand individual risk factors for preventive efforts. Although multiple forms (i.e., physical and psychological) often coexist, few studies have studied the chronicity and developmental classes of physical teen dating violence and examined whether subtypes of trait anger predict teen dating perpetration over time. Thus, the purpose of the current study is to investigate: (a) the developmental group-based patterns of physical teen dating violence; and (b) whether subtypes of trait anger expression predict association in these classes using the Bullying, Sexual, and Dating Violence Trajectories from Early to Late Adolescence in the Midwestern United States, 2007 to 2013 dataset. Group-based trajectory modeling results identified four classes of teen dating violence perpetration (e.g., Accelerating, Abstaining, Desisting, and High Chronic). Multinomial logistic regression results indicated that expressing anger outwardly was positively associated with Desisting and High Chronic patterns, but not Accelerating patterns. These results suggest that there are four classes of teen dating violence perpetration and underscore the effects of expression of trait anger as a risk factor of teen dating violence perpetration. Practical and theoretical implications are discussed.

青少年身体约会实施和特质愤怒表达的纵向轨迹：基于群体的轨迹方法


约会暴力经常发生在青少年中，这需要更好地了解个人风险因素以采取预防措施。尽管多种形式（即身体和心理）经常并存，但很少有研究研究青少年约会暴力的长期性和发展类别，并研究特质愤怒的亚型是否可以预测青少年约会行为随着时间的推移。因此，本研究的目的是调查：（a）基于群体的青少年身体约会暴力的发展模式； (b) 使用 2007 年至 2013 年美国中西部青春期早期到晚期的欺凌、性和约会暴力轨迹数据集，特质愤怒表达的亚型是否可以预测这些类别中的关联。基于群体的轨迹建模结果确定了青少年约会暴力行为的四类（例如，加速、放弃、停止和高度慢性）。多项逻辑回归结果表明，向外表达愤怒与停止和高度慢性模式呈正相关，但与加速模式无关。这些结果表明，青少年约会暴力行为分为四类，并强调了特质愤怒表达作为青少年约会暴力行为风险因素的影响。讨论了实践和理论意义。
