The Experiences in Close Relationships (Brennan et al, Attachment theory and close relationships, 1998) questionnaire is one of the most widely used measures of adult romantic attachment. Despite the advantages of the ECR, the length of this measure may discourage its use in clinical and research contexts. Consequently, the goal of this study was to develop a brief Spanish version of the ECR questionnaire and to examine its psychometric properties when administered to six different Spanish-speaking samples from Chile. Confirmatory factor analyses replicated the two-dimensional structure of the ECR and its invariance across gender. Results also supported the reliability and concurrent validity of our brief Spanish version of the ECR (i.e., Spanish ECR-12), by its association with measures of emotion regulation, dyadic empathy, psychological distress and well-being, and relationship satisfaction. The Spanish ECR-12 can be used by researchers and clinical professionals as an abridged measure of adult attachment.

衡量成人的浪漫依恋：简短的西班牙语版本的亲密经历的心理测量特性。

亲密关系的经历（Brennan等人，依恋理论和亲密关系，1998年）问卷是成人浪漫依恋中使用最广泛的量度之一。尽管ECR有很多优点，但该措施的持续时间可能会阻止其在临床和研究环境中的使用。因此，这项研究的目的是开发一份简短的西班牙语版的ECR调查表，并检查当对来自智利的六个不同的西班牙语样本进行管理时的心理测量特性。验证性因素分析复制了ECR的二维结构及其在性别之间的不变性。结果还与我们的西班牙文版ECR（即西班牙文ECR-12）的可靠性和同时有效性相结合，因为它与情绪调节，二元同理心，心理困扰和幸福感，以及关系满意度。研究人员和临床专业人员可以使用西班牙的ECR-12，作为对成人依恋的一种简化措施。
