Childhood trauma can lead to lifelong detrimental outcomes. Intergenerational trauma should be considered when supporting healthy parent–child relationships. Research is needed on intergenerational trauma in relation to children’s negative life event exposure, which could compound intergenerational trauma. We examined the prevalence of and relations between mother and child traumas in a sample of 88 biological mothers and their preschool-aged children. We coded child negative life events to examine those related to intergenerational trauma. Results showed that mother traumas and child negative life events were positively associated; subtypes of mothers’ traumas (abuse, neglect) and high trauma levels were associated with higher numbers of child negative life events, including those tied to parent trauma. It is necessary to consider how childhood trauma in adults and children is measured, and what analyses can reveal about the intergenerational context, especially considering compounding current, stressful world events.

童年创伤可能导致终生的不利后果。在支持健康的亲子关系时，应考虑代际创伤。需要研究代际创伤与儿童负面生活事件暴露之间的关系，这可能会加剧代际创伤。我们以 88 名亲生母亲及其学龄前儿童为样本，调查了母子创伤的发生率及其之间的关系。我们对儿童负面生活事件进行编码，以检查与代际创伤相关的事件。结果表明，母亲的创伤和孩子的负面生活事件呈正相关；母亲创伤的亚型（虐待、忽视）和高创伤水平与更多的儿童负面生活事件有关，包括那些与父母创伤有关的事件。
