尽管关于囤积症的分类和诊断状况存在争议，但囤积症的分类学研究仍然缺乏，这可能会为分类争论提供信息。本调查在三个大的独立样本中检验了囤积的潜在结构。对三种经过验证的囤积措施的数据进行了分类，包括最大特征值、平均高于减去低于切割和潜在模式因子。分析了两种症状测量，其中一种密切反映了囤积障碍的诊断标准，以及囤积信念的测量。样本1 （n= 2501）代表一般德国人，而样本2 （n= 1149）和样本3 （n=500）由未选择的本科生组成。所有三个样本和分类程序的发现提供了趋同的证据，表明囤积最好被概念化为一种维度结构，在所有个体中都不同程度地存在。研究结果具有跨研究和治疗领域的意义，特别是在评估方法、治疗反应确定和政策决定方面。这些发现强调了对囤积的疾病分类学进行进一步调查的必要性，以帮助我们在研究和治疗工作中进一步验证这一结构，以及将囤积障碍纳入《精神疾病诊断与统计手册》（第5版；DSM-5；美国精神病学协会，2012）的可能性。
Despite controversy regarding the classification and diagnostic status of hoarding disorder, there remains a paucity of research on the nosology of hoarding that is likely to inform the classification debate. The present investigation examined the latent structure of hoarding in three, large independent samples. Data for three well-validated measures of hoarding were subjected to taxometric procedures, including MAXimum EIGenvalue, Mean Above Minus Below A Cut, and Latent-Mode factor. Two symptom measures, one of which closely mirrors the proposed diagnostic criteria for hoarding disorder, and a measure of hoarding beliefs were analyzed. Sample 1 (n=2,501) was representative of the general German population, while Samples 2 (n=1,149) and 3 (n=500) consisted of unselected undergraduate students. Findings across all three samples and taxometric procedures provided converging evidence that hoarding is best conceptualized as a dimensional construct, present in varying degrees in all individuals. Results have implications across research and treatment domains, particularly with respect to assessment approaches, treatment response determination, and policy decisions. These findings underscore the need for further investigations on the nosology of hoarding, to help validate this construct as we move forward with respect to our research and treatment efforts, as well as the potential inclusion of hoarding disorder in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2012).
