Maternal depression and anxiety are potential risk factors to children's language environments and development. Though existing work has examined relations between these constructs, further work is needed accounting for both depression and anxiety and using more direct measures of the home language environment and children's language development. We examined 265 mother-infant dyads (49.6% female, Mage = 17.03 months) from a large city in the Western United States to explore the relations between self-reports of maternal depression and anxiety and observational indices of the home language environment and expressive language as captured by Language Environment Analysis (LENA) and parent-reported language comprehension and production. Results revealed maternal depressive symptoms to be negatively associated with home language environment and expressive language indices. Maternal anxiety symptoms were found to be negatively associated with children's parent-reported language production. These findings provide further evidence that maternal mental health modulates children's home language environments and expressive language.

母亲的抑郁和焦虑是儿童语言环境和发展的潜在危险因素。虽然现有的工作已经检查了这些结构之间的关系，但需要进一步的工作来解释抑郁和焦虑，并使用更直接的家庭语言环境和儿童语言发展的措施。我们检查了 265 对母婴（49.6% 的女性，M年龄= 17.03 个月）从美国西部的一个大城市探索母亲抑郁和焦虑的自我报告与语言环境分析（LENA）和父母报告的家庭语言环境和表达性语言的观察指数之间的关系语言理解和生产。结果显示，母亲的抑郁症状与家庭语言环境和表达性语言指数呈负相关。发现母亲的焦虑症状与孩子的父母报告的语言产生负相关。这些发现提供了进一步的证据，证明母亲的心理健康会调节儿童的家庭语言环境和表达语言。
