《精神疾病诊断和统计手册》第五版(DSM-5)承认了人格病理学的发展视角，因为它建议将人格病理学概念化为适应不良人格特征。以前的研究发现，DSM-5适应不良特质和标准人格特质的五因素模型(FFM)具有共同的潜在维度。尽管DSM-5通常认为DSM-5特征是FFM特征的极端版本，但在青少年中经验证据很少。因此，本研究通过使用项目反应理论(IRT)对青少年样本(n=353)的DSM-5(PID-5)和BFI-2(BFI-2)人格问卷进行了比较。结果表明，除了FFM开放性和精神病性外，所有领域对都有潜在的维度。与一般假设一致，IRT结果表明，在潜在维度的较高水平上，PID-5量表通常比BFI-2量表提供更多的信息。BFI-2量表在较低级别提供了更多的信息。然而，对于FFM的尽责和去抑制，BFI-2量表提供了几乎整个潜在维度的更多信息。研究结果表明成人和青少年在人格病理学的DSM-5概念化方面有相似之处，同时也发现了需要考虑的重要差异。
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) recognizes a developmental perspective on personality pathology due to its proposal to conceptualize personality pathology in terms of maladaptive personality traits. Previous research has found that the DSM-5 maladaptive traits and the Five Factor Model (FFM) for normative personality traits share common underlying dimensions. Although the DSM-5 generally assumes DSM-5 traits to be extreme versions of FFM traits, empirical evidence is scarce in adolescents. The present study therefore extended prior studies by comparing the Personality Inventory for DSM-5 (PID-5) and the Big Five Inventory-2 (BFI-2) in an adolescent sample (n = 353), using Item Response Theory (IRT). Results indicated an underlying dimension for all domain pairs except for FFM Openness and Psychoticism. Consistent with the general assumption, IRT results demonstrated that PID-5 scales generally provided more information than the BFI-2 scales at the upper levels of the latent dimension. The BFI-2 scales provided more information at the lower levels. For FFM Conscientiousness and Disinhibition, however, the BFI-2 scale provided more information for almost the entire range of the latent dimension. The findings indicate similarities in the DSM-5 conceptualization of personality pathology between adults and adolescents, while at the same time identify important differences that need to be considered.
