Mother–child emotion-related conversations, as a practice of parental socialization of emotion, can help children with autism spectrum disorder (ASD) develop socio-emotional skills. This study intends to explore relationships between mother–child conversations about emotions and socio-emotional skills of children with ASD by accounting for the moderating role of children personality traits and mothers’ emotional openness. Mothers of children with ASD (n = 49) responded to five questionnaires describing their conversations about emotions, emotional openness as well as their child’s socio-emotional skills and personality. We conducted hierarchical regression and moderation analyses. Our findings indicate that frequent mother–child conversations about emotions significantly predict higher emotional regulation and Theory of Mind (ToM) abilities in children with ASD (p < 0.05). Moreover, children’s consciousness and openness to experience, along with mothers’ emotional openness significantly moderate the relation between mother–child conversations about emotions and children’s ToM skills (p < 0.05). Mother–child conversations about emotions, as a practice of parental socialization of emotion, could be beneficial for children with ASD. Children’s personality traits and mothers’ openness to emotion may act as a protective factor of ToM skills in children with ASD.

母子情感对话作为父母情感社会化的一种实践，可以帮助自闭症谱系障碍（ASD）儿童发展社会情感技能。本研究旨在通过考虑儿童人格特征和母亲情绪开放性的调节作用，探讨自闭症儿童关于情绪和社会情绪技能的母子对话之间的关系。ASD 儿童的母亲 (n = 49) 对五份问卷进行了回复，问卷描述了他们关于情绪、情绪开放性以及孩子的社会情绪技能和个性的对话。我们进行了分层回归和适度分析。p  < 0.05)。此外，儿童的意识和经验开放度以及母亲的情感开放度显着调节了母子关于情感的对话与儿童的 ToM 技能之间的关系（p  < 0.05）。作为父母情感社会化的一种实践，关于情绪的母子对话可能对患有 ASD 的儿童有益。儿童的性格特征和母亲对情绪的开放性可能是 ASD 儿童 ToM 技能的保护因素。
