Adverse childhood experiences negatively impact future violence, victimization, perpetration, health, and lifelong development. The aim of the present study was to systematically review the scientific evidence of empirical studies on the association between maternal childhood adversity in a familial context, including maltreatment, household challenges, and later maternal negative parenting. A search was performed in the PubMed, PsycINFO, Web of Science, SciELO, and LILACS databases, using the combination of the following keywords: (neglect OR abuse OR maltreatment OR harsh parenting OR punishment OR discipline OR negative parenting practices) AND (adverse childhood experiences OR early adversity OR cycle of violence OR cycle of maltreatment OR history of maltreatment) AND (mother OR maternal). The results of 29 studies showed predominantly significant direct associations between maternal childhood adversities and negative parenting with their children (83%). Parental stress was also significantly associated with a maternal history of childhood adversities. Focusing on the type of maltreatment practices, there were similar intergenerational transmission types: homotypic and heterotypic. Few studies have examined the protective factors that could buffer the negative impact of a maternal childhood history of adversities on later negative parenting.

不良的童年经历会对未来的暴力、受害、犯罪、健康和终身发展产生负面影响。本研究的目的是系统地回顾关于家庭背景下母亲童年逆境（包括虐待、家庭挑战和后来的母亲消极养育）之间关联的实证研究的科学证据。使用以下关键字的组合在 PubMed、PsycINFO、Web of Science、SciELO 和 LILACS 数据库中进行了搜索：（忽视或虐待或虐待或严厉的养育或惩罚或纪律或消极的养育做法）和（不良童年经历或早期逆境或暴力循环或虐待循环或虐待史）和（母亲或母亲）。29 项研究的结果表明，母亲的童年逆境与对孩子的消极养育之间存在显着的直接关联 (83%)。父母压力也与母亲的童年逆境史显着相关。从虐待行为的类型来看，存在相似的代际传播类型：同型和异型。很少有研究考察可以缓冲母亲童年逆境史对后来消极养育的负面影响的保护性因素。有相似的代际传播类型：同型和异型。很少有研究考察可以缓冲母亲童年逆境史对后来消极养育的负面影响的保护性因素。有相似的代际传播类型：同型和异型。很少有研究考察可以缓冲母亲童年逆境史对后来消极养育的负面影响的保护性因素。
