为探究流动儿童亲子依恋与同伴依恋和内化问题的关系,采用修订后的父母与同伴依恋问卷、自我调节量表中的情绪调节分量表、儿童拒绝敏感性问卷和儿童长处与困难问卷对230名流动儿童进行调查。结果发现,亲子与同伴依恋对流动儿童的拒绝敏感性和内化问题均具有显著负向预测作用,对情绪调节能力均具有显著正向预测作用。情绪调节能力分别在亲子和同伴依恋与内化问题之间起到部分中介作用。拒绝敏感性和情绪调节能力在同伴依恋与内化问题之间起到链式中介作用。To explore the relationship between parental and peer attachment and internalizing problems in migrant children, a survey was conducted with 230 migrant children using the revised Inventory of Parent and Peer Attachment (IPPA), the Emotion Regulation subscale of the Self-Regulation Scale, the Children’s Rejection Sensitivity Questionnaire, and the Strengths and Difficulties Questionnaire (SDQ). The results showed that both parental and peer attachment significantly negatively predicted rejection sensitivity and internalizing problems, while positively predicting emotion regulation ability. Emotion regulation ability partially mediated the relationship between both types of attachment and internalizing problems. Additionally, rejection sensitivity and emotion regulation ability jointly acted as a chain mediation mechanism between peer attachment and internalizing problems.
