Alexithymia is a personality trait with its primary characteristic being a deficiency in handling emotions. Previous literature has found inconsistent findings on the relationship between insecure attachment and alexithymia. Therefore, this study adopted a three-level random-effect meta-analysis approach with the goal of understanding the underlying mechanism between insecure attachment and alexithymia based on the 415 effects from 67 studies. As shown in our findings, insecure attachment was significantly and positively correlated to alexithymia (r = 0.306; 95% CI: 0.286, 0.325; p < 0.0001). Furthermore, the moderator analysis demonstrated that category of insecure attachment (F _{(4, 399)} = 5.896; p < 0.001), measurement of insecure attachment (F _{(13, 397)} = 2.074; p = 0.015), and facet of alexithymia (F _{(4, 406)} = 26.218; p < 0.001) showed significant moderating effects. In terms of different categories of attachment, individuals with anxious attachment could show more severe alexithymia than those with preoccupied attachment. As for diverse measurements of attachment, the moderating effect of the Experiences in Close Relationship (ECR) on the relationship between insecure attachment and alexithymia is the most significant, followed by the Attachment Style Questionnaire (ASQ), then the Relationship Style Questionnaire (RSQ), with the Relationship Questionnaire (RQ) being the least. Regarding various facets of alexithymia, the significance of their moderating effect is, in descending order, externally oriented thinking, general alexithymia, and difficulty describing feelings. Overall, this review confirms the aggravating effect of insecure attachment on alexithymia, providing a feasible gateway to prevent emotional management impairments, that is, reducing the likelihood of high-level alexithymia by averting individuals from developing insecure attachment.

述情障碍是一种人格特质，其主要特征是缺乏处理情绪的能力。以前的文献发现不安全依恋与述情障碍之间关系的研究结果不一致。因此，本研究采用三水平随机效应荟萃分析方法，目的是基于 67 项研究的 415 种效应，了解不安全依恋与述情障碍之间的潜在机制。正如我们的研究结果所示，不安全依恋与述情障碍显着正相关（r = 0.306；95% CI：0.286、0.325；p  < 0.0001）。此外，调节分析表明不安全依恋类别 ( F _{(4, 399)}  = 5.896; p  < 0.001)，不安全依恋的测量 (F _{(13, 397)}  = 2.074; p  = 0.015)，以及述情障碍的方面 ( F _{(4, 406)}  = 26.218; p < 0.001) 显示出显着的调节作用。就不同类型的依恋而言，焦虑型依恋的个体比专注型依恋的个体表现出更严重的述情障碍。在不同的依恋测量中，亲密关系经历（ECR）对不安全依恋与述情障碍之间关系的调节作用最显着，其次是依恋风格问卷（ASQ），然后是关系风格问卷（RSQ） ，其中关系问卷（RQ）最少。关于述情障碍的各个方面，其调节作用的重要性按降序排列为外向性思维、一般性述情障碍和难以描述感受。全面的，
