Although conscious aspects of attachment representations can be effectively assessed in middle childhood, the few available self-reports are based on different operationalizations of attachment and do not always show adequate psychometric properties. The current study aimed to develop and evaluate the psychometric properties of the Attachment in Middle Childhood Questionnaire (AMCQ). Using three independent samples of Italian children (M_age = 10 years, 52% = girls), in three interrelated studies we (1) selected a pool of items from existing questionnaires, adapted them to the same response format, and subjected them to exploratory factor analysis; (2) performed confirmatory factor analyses on the retained items; and (3) used structural equation modeling to assess the factor structure, external validity, and invariance across gender and age groups. The final 15-item questionnaire comprised two dimensions (anxiety and avoidance) and a supplementary scale (security). Overall, results supported the reliability and validity of the AMCQ for Italian children.

尽管依恋表征的意识方面可以在童年中期进行有效评估，但少数可用的自我报告是基于依恋的不同操作化，并且并不总是表现出足够的心理测量特性。当前的研究旨在开发和评估童年中期依恋问卷（AMCQ）的心理测量特性。使用意大利儿童的三个独立样本（ M_年龄= 10 岁，52% = 女孩），在三项相互关联的研究中，我们 (1) 从现有调查问卷中选择了一组项目，将其调整为相同的回答格式，并对它们进行探索性研究因素分析； （2）对保留项目进行验证性因素分析； (3) 使用结构方程模型来评估因子结构、外部效度以及跨性别和年龄组的不变性。最终的 15 项调查问卷包括两个维度（焦虑和回避）和一个补充量表（安全感）。总体而言，结果支持 AMCQ 对意大利儿童的可靠性和有效性。
