This study used multinomial logistic regression to examine relationships between child-care experience (in the context of overall family functioning) and preschool attachment. Attachment behavior was assessed at 36 months with the Strange Situation, and A, B, C, and D attachment classifications were assigned using the MacArthur coding system. Maternal sensitivity was the strongest predictor of preschool attachment classification. With respect to child-care effects, as at 15 months, no child-care factors (quantity, quality, or type) predicted. in and of themselves, attachment security at 36 months. However, 1 of 3 interactions involving child care that were detected at 15 months reemerged at 36 months: When maternal sensitivity was low, more hours per week in care somewhat increased the risk of the insecure-ambivalent (C) classification. There was significant but modest stability of attachment classifications from 15 to 36 months, especially for children with A and C classifications.
本研究采用多项逻辑回归分析，以检验儿童保育经历（在整体家庭功能背景下）与学前依恋之间的关系。在36个月时通过陌生情境法评估依恋行为，并使用麦克阿瑟编码系统对A、B、C和D依恋类型进行分类。母亲的敏感性是学前依恋类型最强的预测因素。关于儿童保育的影响，与15个月时的情况一样，没有任何儿童保育因素（数量、质量或类型）本身能够预测36个月时的依恋安全性。然而，在15个月时检测到的涉及儿童保育的3种相互作用中有1种在36个月时再次出现：当母亲的敏感性较低时，每周较长的保育时长会略微增加不安全矛盾型（C型）依恋的风险。从15个月到36个月，依恋类型具有显著但适度的稳定性，尤其是对于A类和C类儿童。
