Current dimensional measures of early personality pathology (e.g., the Dimensional Personality Symptom Item Pool, DIPSI; De Clercq, De Fruyt, Van Leeuwen, & Mervielde, 2006) describe personality difficulties within a 4-dimensional framework. The present study corroborates recent evidence on the relevance of including a 5th Oddity-related domain for a more comprehensive description of personality pathology, and presents the construction of an empirically based taxonomy of early Oddity features. Psychometric and factor analytic procedures were conducted on self- and maternal ratings of adolescents (N = 434), resulting in 4 internally consistent facets that empirically collapse in 1 higher-order "Oddity" factor. From a structural perspective, this Oddity factor emerged as a clear 5th factor beyond the earlier proposed 4-dimensional structure of child and adolescent personality pathology. Significant associations of Oddity with both general and maladaptive trait equivalents support the construct validity of this 5th factor, and challenge current hypotheses on the applicability of the continuity hypothesis on general and maladaptive trait variance within the openness field. The results further suggest that Oddity traits are meaningfully associated with general psychopathology at a young age. These findings are discussed in terms of the importance of including a 5th Oddity-related factor in dimensional models of developmental personality pathology in order to acquire a more comprehensive description of the building blocks that underlie early personality difficulties.
早期人格病理学的当前维度测量方法（例如，维度人格症状项目库，DIPSI；De Clercq、De Fruyt、Van Leeuwen和Mervielde，2006）在一个四维框架内描述人格困难。本研究证实了最近的证据，即纳入与怪异相关的第五个领域对于更全面地描述人格病理学具有相关性，并提出了基于实证的早期怪异特征分类法的构建。对青少年的自我评定和母亲评定进行了心理测量和因素分析程序（N = 434），得出了4个内部一致的方面，这些方面在实证上合并为1个高阶“怪异”因素。从结构角度来看，这个怪异因素作为一个明确的第五个因素出现，超越了先前提出的儿童和青少年人格病理学的四维结构。怪异与一般和适应不良特质等价物的显著关联支持了这个第五个因素的结构效度，并挑战了当前关于开放性领域内一般和适应不良特质方差连续性假设适用性的假设。结果进一步表明，怪异特质在年轻时与一般精神病理学有意义地相关。本文讨论了这些发现，涉及在发展性人格病理学的维度模型中纳入与怪异相关的第五个因素的重要性，以便更全面地描述早期人格困难背后的构成要素。
