The formation of intense emotional attachments to objects, difficulty parting with possessions, and the extreme accumulation of clutter are key features of Hoarding Disorder (HD). Although substantial literature implicates processes such as dysfunctional beliefs and maladaptive emotional cycles in HD, little is known about the vulnerability factors that lead to their development and hoarding symptomatology. The current review sought to systematically collate and integrate findings from studies investigating the relationship between hoarding symptoms and three proposed vulnerability factors: i) interpersonal attachment, ii) early family environment, and iii) traumatic or adverse life events. A comprehensive search of the databases PsycInfo, PubMed, and Scopus identified a total of 39 studies for inclusion. The results presented a complex pattern that supported the presence of relationships between insecure attachment, cold and controlling family experiences, and exposure to adverse life events with increased hoarding severity. However, the specificity of these factors to HD over other clinical groups remains unclear and findings are limited by the heterogenous and small number of studies. We conclude by discussing the clinical implications and limitations of these findings and propose new directions for future research.

对物体形成强烈的情感依恋、难以与财产分开以及极度堆积杂物是囤积症 (HD) 的主要特征。尽管大量文献涉及 HD 中功能失调的信念和适应不良的情绪循环等过程，但对导致其发展和囤积症状的脆弱性因素知之甚少。目前的审查试图系统地整理和整合调查囤积症状与三个拟议脆弱性因素之间关系的研究结果：i) 人际关系，ii) 早期家庭环境，以及 iii) 创伤性或不利的生活事件。对数据库 PsycInfo、PubMed 和 Scopus 的全面搜索确定了总共 39 项研究纳入。结果提出了一个复杂的模式，支持不安全的依恋、寒冷和控制性的家庭经历，以及暴露于囤积严重程度增加的不良生活事件之间存在关系。然而，与其他临床组相比，这些因素对 HD 的特异性仍不清楚，并且研究结果受到异质性和少量研究的限制。我们最后讨论了这些发现的临床意义和局限性，并为未来的研究提出了新的方向。与其他临床组相比，这些因素对 HD 的特异性仍不清楚，并且研究结果受到异质性和少数研究的限制。我们最后讨论了这些发现的临床意义和局限性，并为未来的研究提出了新的方向。与其他临床组相比，这些因素对 HD 的特异性仍不清楚，并且研究结果受到异质性和少数研究的限制。我们最后讨论了这些发现的临床意义和局限性，并为未来的研究提出了新的方向。
