The five-factor model of personality disorder (FFMPD) hypothesizes that the traditionally adaptive five-factor model (FFM) poles (e.g., agreeableness) include maladaptive variants. However, "bloated specific factors" (BSFs), which are artifactual factors that emerge when a specific facet of a broader construct is over-represented, complicate research on the maladaptive variants. Twenty-five sets of factor analyses are completed herein demonstrating that items from maladaptive trait facet scales form BSFs when over-represented in factor analyses with other FFM indicators, separating from the higher-order domains in which they were originally located. These results held in 23 of 25 cases. Ensuring balanced collections of scales representing constructs would help researchers avoid BSFs. The implications of BSFs for future research on personality structure are discussed.
人格障碍五因素模型（FFMPD）假设，传统上具有适应性的五因素模型（FFM）两极（如宜人性）包含适应不良的变体。然而，“膨胀的特定因素”（BSFs）是当一个更广泛结构的特定方面被过度代表时出现的人为因素，这使对适应不良变体的研究变得复杂。本文完成了25组因素分析，结果表明，当适应不良特质层面量表的项目在与其他FFM指标的因素分析中被过度代表时，会形成BSFs，并与它们最初所属的高阶领域分离。25个案例中有23个案例的结果都是如此。确保代表结构的量表收集保持平衡，将有助于研究人员避免出现BSFs。本文还讨论了BSFs对未来人格结构研究的影响。
