This study used longitudinal data to examine the transactional associations between mothers’ spanking and mother–child relationship quality with children’s externalizing behaviors in the context of intimate partner violence (IPV). Data came from a sample of 1,152 low-income mothers with children age 10–14 years. Results showed that past-year IPV triggered transactional associations by increasing children’s externalizing behaviors which, in turn, increased spanking and subsequently more externalizing behaviors. Transactional associations were also found for relationship quality. All outcomes used were mothers-reported except relationship quality. Implications for practice include the importance of the mother–child dyad and their reciprocal processes in assessment and treatment.

本研究使用纵向数据来检验母亲打屁股和母子关系质量与儿童在亲密伴侣暴力（IPV）背景下的外化行为之间的交易关联。数据来自 1,152 名有 10-14 岁儿童的低收入母亲的样本。结果表明，过去一年的 IPV 通过增加儿童的外化行为触发了交易关联，这反过来又增加了打屁股和随后的外化行为。还发现了关系质量的交易关联。除关系质量外，所有使用的结果都是母亲报告的。实践的意义包括母子二人组的重要性及其在评估和治疗中的相互过程。
