The type and frequency of children's exposure to intimate partner violence (IPV) are considered as key variables in understanding children's heightened risk of externalizing symptoms. Notably, children's exposure to IPV has been primarily measured using mothers' reports of their own victimization. However, mothers and children might differently perceive children's exposure to physical IPV. To date, no research has investigated multi-rater reporting discrepancies in child's exposure to physical IPV and whether such discrepancies would be linked to externalizing symptoms. This study aimed to identify patterns of mother-child discrepancies in child's exposure to physical IPV and examine whether those patterns would be associated with children's externalizing symptoms. Participants were mothers who have experienced police-reported male-perpetrated IPV and their children (n = 153; 4-10 years). Latent profile analysis identified three profiles of mother-child discrepancies: a concordant group reporting high IPV exposure; a discordant group with mothers and children reporting high and low child's IPV exposure, respectively; a second discordant group with mothers and children reporting low and moderate IPV exposure, respectively. Profiles of mother-child discrepancies were differentially associated with children's externalizing symptoms. Findings suggest that discrepancies among informants' ratings of children's IPV exposure might have important implications for measurement, assessment, and treatment.

母子报告中儿童遭受亲密伴侣暴力的差异：与外化症状的关联。

儿童遭受亲密伴侣暴力 (IPV) 的类型和频率被认为是了解儿童外化症状风险增加的关键变量。值得注意的是，儿童接触 IPV 的情况主要是根据母亲对自己受害情况的报告来衡量的。然而，母亲和孩子对孩子接触物理 IPV 的看法可能不同。迄今为止，还没有研究调查多评估者报告的儿童接触物理 IPV 的差异，以及这种差异是否与外在症状有关。本研究旨在确定儿童接触物理 IPV 的母子差异模式，并检查这些模式是否与儿童的外化症状相关。参与者是经历过警方报告的男性实施 IPV 的母亲及其孩子（n = 153；4-10 岁）。潜在概况分析确定了母子差异的三个概况：报告高 IPV 暴露的一致组；一个不一致的群体，母亲和儿童分别报告儿童 IPV 暴露量高和低；第二组不一致，母亲和儿童分别报告低度和中度 IPV 暴露。母子差异的概况与儿童的外化症状有不同的相关性。研究结果表明，知情者对儿童 IPV 暴露评级的差异可能对测量、评估和治疗产生重要影响。
