Research supports a strong relationship between childhood maltreatment and internalizing psychopathology (e.g., anxiety and depression), and features of personality are assumed to explain some of this relationship. In this study, we proposed a model in which maladaptive traits mediate the effect of childhood trauma history on internalizing symptoms in adult individuals. A mixed sample (N = 462) composed of 142 psychiatric patients and 320 community-dwelling individuals completed the Childhood Trauma Questionnaire (CTQ), the Personality Inventory for DSM-5 (PID-5), and the Symptom Checklist (SCL-27) for internalizing psychopathology. The effect of childhood traumas explained 34% of the variance in internalizing symptoms while controlling for the influence of age and gender. The traits accounted for 78% of this effect, which was predominantly exerted through the domains of Negative Affectivity, Detachment, and Psychoticism, and specifically through the facets of Depressivity, Suspiciousness, Anxiousness, Perceptual Dysregulation, and Distractibility. This finding provides preliminary support for the proposed model indicating that the aforementioned maladaptive trait domains potentially function as mediating links by which childhood traumas are translated into internalizing symptoms in adulthood. However, these findings must be interpreted with caution due to the cross-sectional and retrospective mono-method design of this study. Clinical implications are discussed in relation to transdiagnostic treatment and the potential value of specifying trait domain specifiers in ICD-11 and DSM-5 models of personality disorders.
研究支持儿童期虐待与内化性精神病理学（例如焦虑和抑郁）之间存在强烈关系，并且假定人格特征可以解释这种关系的某些部分。在这项研究中，我们提出了一个模型，其中适应不良特征可以调节童年创伤史对成年个体内化症状的影响。一个混合样本（N=462）由 142 名精神病患者和 320 名社区居民组成，他们完成了童年创伤问卷（CTQ）、DSM-5 人格量表（PID-5）和内化性精神病理学症状检查表（SCL-27）。在控制年龄和性别影响的情况下，童年创伤对内化症状的变异解释了 34%。这些特征占此影响的 78%，主要通过消极情感、分离和精神病性的领域发挥作用，特别是通过沮丧、多疑、焦虑、知觉失调和注意力分散的方面发挥作用。这一发现为所提出的模型提供了初步支持，表明上述适应不良特征领域可能作为中介环节，将童年创伤转化为成年后的内化症状。然而，由于这项研究的横截面和回顾性单方法设计，必须谨慎解释这些发现。讨论了临床意义，涉及到跨诊断治疗以及在 ICD-11 和 DSM-5 人格障碍模型中指定特征领域指定符的潜在价值。
