This study examined whether maternal disrupted communication, which is associated with disorganized infant attachment, also characterizes mothers of ambivalent infants. The study, conducted in Israel, included a Jewish sample (N = 163; 68 Girls) from diverse socioeconomic status, collected between 1991 and 1993 in an earlier study. The sample over-represented ambivalent and disorganized attachments. Attachment was assessed in the Strange Situation Procedure (SSP) at 12 months and disrupted communication was coded from the SSP using the Atypical Maternal Behavior Instrument for Assessment and Classification (AMBIANCE; Lyons-Ruth et al., 1999). Mothers of ambivalent infants showed higher disrupted communication than mothers of secure, avoidant, and disorganized infants. The findings shed further light on the correlates of ambivalent attachment and call for research regarding maternal and infant characteristics that differentiate ambivalent versus disorganized attachment.

情感交流中断是婴儿母亲的特征，他们的依恋杂乱无章，但也有矛盾的依恋：以色列的一项研究

这项研究检查了母亲是否破坏了与婴儿依恋紊乱相关的沟通障碍，这也是矛盾婴儿母亲的特征。该研究在以色列进行，包括一个犹太人样本（N = 163; 68 名女孩）来自不同社会经济地位，收集于 1991 年至 1993 年间的一项早期研究。样本过度代表了矛盾和杂乱无章的依恋。依恋在 12 个月时在陌生情况程序 (SSP) 中进行评估，并使用用于评估和分类的非典型母体行为工具 (AMBIANCE; Lyons-Ruth 等人，1999) 从 SSP 中对中断的交流进行编码。矛盾型婴儿的母亲比安全型、回避型和杂乱无章婴儿的母亲表现出更高的沟通障碍。这些发现进一步阐明了矛盾依恋的相关性，并呼吁研究区分矛盾依恋与无组织依恋的母婴特征。
