Children exposed to maltreatment are at risk of experiencing intimate partner violence (IPV) and behavioral problems. This study examined different forms of family violence that co-occur and their relationship to children’s externalizing behaviors across developmental stages (early childhood, middle childhood, adolescence). Longitudinal data (N = 1,987) at baseline and 18 months and 36 months post-baseline from the NSCAW II were used. Mixture modeling was employed in which latent class models estimated subgroups of children who experienced co-occurring forms of family violence; regression models estimated which subgroups of children were at risk of externalizing behaviors. Three latent classes were identified across developmental stages: high family violence, low family violence, and child physical abuse and psychological aggression. For children in early childhood, a fourth class was identified: partner and child physical abuse and child psychological aggression. Results from regression models revealed differences in externalizing scores by class membership across developmental age groups and over time. That distinct classes of child maltreatment and IPV co-occur and differentially impact children’s behavior suggests a need for strong prevention and intervention responses to address children’s dual maltreatment and IPV exposure.

遭受虐待的儿童有遭受亲密伴侣暴力 (IPV) 和行为问题的风险。本研究调查了同时发生的不同形式的家庭暴力及其与儿童在各个发展阶段（幼儿期、幼儿期、青春期）外化行为的关系。纵向数据 ( N= 1,987) 在基线和基线后 18 个月和 36 个月使用 NSCAW II。使用混合模型，其中潜在类别模型估计经历过共同发生的家庭暴力形式的儿童亚组；回归模型估计哪些儿童亚组有外化行为的风险。在各个发展阶段确定了三个潜在类别：高家庭暴力、低家庭暴力以及儿童身体虐待和心理攻击。对于幼儿期的儿童，确定了第四类：伴侣和儿童的身体虐待以及儿童的心理攻击。回归模型的结果揭示了不同发育年龄组和随着时间的推移，班级成员的外化分数存在差异。
